Guest guest Posted September 1, 2012 Report Share Posted September 1, 2012 KILLING and INJURING But its all in a GOOD CAUSE Various snippets on aluminium sulphate and its lethal potential Note that WITHOUT the Camelford poisoning incident our knowledge would be largely limited to that of the immense suffering by dialysis cases only. The harm from Camelford has been ignored so our knowledge from this is sparse and disputed. Pyschiatrists of international repute (Simon Wesseley and trainer of Fombomme?) DENY aluminium harm and most lessons we could have learned from Camelford are now LOST (but not burnt or stolen). The INCHEM document contrasts with the first document on safety which tells us nothing except dont worry. The INCHEM document may not have been read by vaccine makers as the toxicity for babies (they certainly didn't read of mercury harm in vaccines for 30 years) by injection and as shown to dialysis patients is a very real, powerful and immensely dangerous toxin at levels that make the aluminium in our vaccines look like a marvellous candidate for administering the death penalty in place of sea salt injections as at present. Harm shown from 60 parts per billion and less from current knowledge. But some vaccines for infants contain 625 000 parts per billion with this dose repeated time after time after time to infants in the first two years. Potential for harm without any need for synergy is quite quite remarkable. WHO recommend a max of 200 parts per billion in water already above levels of harm shown by researchers at 60 parts per billion. Obviously they think drinking the stuff is less hazardous than injecting it and they may well be correct. Well they can't get it wrong all the time. Consider: 'Dialysis dementia' involves the accumulation of aluminium, mainly in the brain, in patients on haemodialysis So we know that injections of any aluminium will have the potential to enter the brain of those with established blood brain barriers so what is the potential in infants with no blood brain barrier. Life just gets easier or should that be DEATH. This from 60ppb or less for adults but babies take 625 000 ppb on the chin and in their arms legs and mouths without blinking an eyelid but often crying and crying and crying until exhausted. Still its good to be « protected ». But who is protected by sending baby to an early death (Harry ) or a life on the ASD spectrum? Note also the total abandonment of aluminium in perspirants not because its toxic but because it doesnt work? Now how have these manufacturers in Big Pharma been so easily fooled for generations? If they are this stupid lets hops they won't take to injecting toxic levels of mercury and alumumium in babies before they are even born. OOOPS! Of course they wouldnt then add phosphorus, fluoride or lemon juice to enhance the toxicity WOULD THEY? OOOPS! OOOPS! and OOPS! Of course we do have the protection of vaccine regulators and legal laws so perhaps the unchangeable nature of chemical reactions is controlled by these regulators and laws, so we have nothing to worry about. I mean these experts have 100's of peer reviewed papers, have written the last three volumes of vaccine science so perhaps there expertise takes precedence over simple schoolboy chemistry. And of course if all else fails we have the protection of the vaccine courts to gets fair and due compensation as per Mrs Sally who got double life for two lost boys after vaccines and a corrupt autopsy that left her body to rot and ferment for weeks so they could find enough alcohol to make a couple of bottles of whisky. (grapes or almost anything left for a few weeks produces alcohol at the rate of millions of molecules per second). Or better Mrs Fletcher who started a vaccine group and after merely 18 years obtained compensation at about 40 per cent of prices 20 years ago and not enough to pay for her time and effort. At an average workmans slary for this time she could have earned this amount many times over. Protection by money to pay for harm is ZERO. And protection by safe vaccines is less than ZERO. Read any small print and count the dead bodies from vaccine trials which were ok'd as safe for mass injections into anybody except them. 2ppb mercury toxic but 25 000ppb in vaccines just fine. And in 2010 60ppb aluminium is toxic but 625 000 in vaccines for baby just great. FEEL the protection of experts, vaccine makers and those regulators at CDC that we rely on for safety. OMG I feel ill. Of course my maths needs checking and it may be that the 625 000 is the amount before harm and the 600 is what they put in our childs vaccines but I wouldn- bet on it. But I would bet that there are many bloggers out there who will tell you that if 600 is toxic then 625 000 will be just fine for baby because us chemists aren' really good chemists andve lost credibility. I had to smile when one of these was an acknowledged expert and knew mercury was just fine and couldnt hurt you. He was so confident of this his family get the full blast of mercury from an emitter 200 yards from his house with no adverse effects to him or his wife. So one day perhaps I will agree that 625 000 is good when 600 is bad but I am still waiting for that cheque to come through in the post. Or for some epidemiologists in comes every day. (dolly boy RIP) http://www.inchem.org/documents/ukpids/ukpids/ukpid34.htm Uses Aluminium sulfate is used in water purification and as a mordant in dyeing and printing textiles. In water purification, it causes impurities to coagulate which are removed as the particulate settles to the bottom of the container or more easily filtered. This process is called coagulation or flocculation. When dissolved in a large amount of neutral or slightly-alkaline water, aluminium sulfate produces a gelatinous precipitate ofaluminium hydroxide, Al(OH)3. In dyeing and printing cloth, the gelatinous precipitate helps the dye adhere to the clothing fibers by rendering the pigment insoluble. Aluminium sulfate is sometimes used to reduce the pH of garden soil, as it hydrolyzes to form the aluminium hydroxideprecipitate and a dilute sulfuric acid solution. An example of what changing the pH level of soil can do to plants is visible when looking at the Hydrangea macrophylla. The gardener can add aluminium sulfate to the soil to reduce the pH level which in turn will result in the flowers of the Hydrangea turning a different color. Aluminium sulfate is the active ingredient of some antiperspirants; however, beginning in 2005 the US Food and Drug Administration no longer recognized it as a wetness reducer. Aluminium sulfate is usually found in baking powder, where there is controversy over its use due to concern regarding the safety of adding aluminium to the diet. In construction industry it is used as waterproofing agent and accelerator in concrete. Another use is a foaming agent in fire fighting foam. It is also used in styptic pencils, and pain relief from stings and bites. It can also be very effective as a molluscicide, killing spanish slugs. Symptoms  irritation skin, respiratory system; skin burns Target Organs  Skin, respiratory system Aluminium sulphate is relatively non toxic. In 1988, contamination of drinking water with aluminium sulphate led to a variety of acute symptoms (Lowermoor Incident Health Advisory Group, 1991) MECHANISM OF TOXICITY There is experimental evidence that aluminium inhibits bone mineralization partly by the deposition of aluminium at the osteoid/calcified-bone boundary thereby directly inhibiting calcium influx, and partly by aluminium accumulation in the parathyroid glands with suppression of parathyroid hormone secretion (Visser and Van de Vyver, 1985; Berland et al, 1988; Firling et al, 1994). Proposed mechanisms of aluminium-induced neurotoxicity include free-radical damage via enhanced lipid peroxidation, impaired glucose metabolism, effects on signal transduction and protein modification and alterations in the axunal transport and phosphorylation state of neurofilaments (Birchall and Chappell, 1988; Exley and Birchall, 1992; Erasmus et al, 1993; Winship 1993; Haug et al, 1994; Joshi et al, 1994; Strong, 1994). TOXICOKINETICS Absorption In a healthy adult only approximately 15 µg of the average daily dietary aluminium intake of 3-5 mg is absorbed (Winship, 1992). The intestinal absorption of aluminium is enhanced by citrate which is found frequently in effervescent drug formulations. Main and Ward (1992) reported a reversible increase in the serum aluminium concentration from 67.5 to 499.5 µg/L in a patient on haemodialysis taking oral aluminium hydroxide when she was also given an effervescent analgesic containing sodium citrate. Conversely the bioavailability of aluminium in aqueous solution is greatly reduced by silica, such that the toxicity of aluminium-containing phosphate binders may be reduced significantly by the co-administration of dissolved silica (Birchall, 1993). In dialysis patients with aluminium overload, endogenous silicon may serve a protective role in limiting tissue aluminium uptake (Fahal et al, 1994). There may also be implications for domestic water supplies if a high silicic acid concentration evades any hazards posed by aluminium sulphate in water (Birchall, 1993). Distribution More than 90 per cent of absorbed aluminium is bound to transferrin which does not cross the blood-brain barrier readily. The remaining ten per cent is associated with low molecular weight complexes, such as citrate, which can accumulate in brain tissue. In the body aluminium is stored mainly in bone and liver. Excretion Aluminium is excreted predominantly via the kidneys and therefore will accumulate in patients with renal failure (Alfrey, 1980). Preterm infants also have a limited ability to excrete aluminium and there are reports of accumulation in infants on long-term parenteral nutrition (Sedman et al, 1985). Tsou et al (1991) demonstrated significantly higher plasma aluminium concentrations (mean 37.2 µg/L) in normal infants receiving oral aluminium-containing antacids for a prolonged period compared to controls but this was not associated with adverse clinical effects. Ingestion Acute aluminium sulphate ingestion causes primarily gastrointestinal upset though neuropsychological and musculoskeletal sequelae were also reported in those who drank water to which 20 tonnes of eight per cent aluminium sulphate had accidentally been added in Camelford, Cornwall in 1988 (see below). However, a group reviewing this incident concluded that although " early symptoms, such as gastrointestinal disturbances, rashes and mouth ulcers, could probably be attributed to the toxic effects of the incident....The research reported to us does not provide convincing evidence that harmful accumulation of aluminium has occurred, nor that there is greater prevalence of ill-health due to toxic effects of the water in the exposed population " (Lowermoor Incident Health Advisory Group, 1991). Gastrointestinal toxicity Following the Camelford incident a variety of acute symptoms were reported (Eastwood et al, 1990; Lowermoor Incident Health Advisory Group, 1991), mainly mild gastrointestinal disturbance and mouth ulcers (McMillan et al, 1993b). Water aluminium concentrations recorded at the time ranged from 30 to 620 mg/L (WHO recommended maximum aluminium concentration in drinking water is 200 µg/L) (Eastwood et al, 1990; WHO, 1993). The low pH of the water also led to leaching of other metals, such as copper, from the distribution pipes so that those washing in the water developed green-discoloration of their hair. Substantial ingestion of aluminium sulphate causes burning in the mouth and throat, gingival necrosis, nausea, vomiting, diarrhoea, abdominal pain and, in severe cases, haemorrhagic gastritis with circulatory collapse (Gosselin et al, 1984; Royal Society of Chemistry, 1989; Meditext, 1995). Spira (1933) reported dry mouth and throat, anorexia, nausea and vomiting, glossitis, stomatitis, gingivitis and hiccup (in addition to cutaneous and neurological symptoms) suspected to be caused by the ingestion of elemental aluminium plus " aluminized " tap water. There are, however, no case reports of substantial aluminium sulphate ingestion in the literature over at least the last 30 years. Neuropsychological toxicity McMillan et al (1993b) reported " possible impairment of memory " in those who drank aluminium sulphate-contaminated water in Camelford. Serial neuropsychological assessments of 10 individuals between eight and 26 months after the incident showed mild cognitive impairment but a causal link with aluminium exposure could not be verified and in no patient was there evidence of residual aluminium in bone or plasma McMillan et al, 1993b). Retrospective psychological testing on 39 children from schools in the contaminated area showed no significant differences compared to unexposed children (McMillan et al, 1993a). Muscle twitching, limb paraesthesiae, arthralgia, neuralgia, giddiness, depression and lassitude have been attributed to the ingestion of elemental aluminium and aluminium contaminated tap water (Spira, 1933) but this was speculative. Musculoskeletal toxicity Some individuals who drank the aluminium sulphate-contaminated water in Camelford later complained of joint and muscle pains and fatigue (Anonymous, 1991; McMillan et al, 1993b). Bone toxicity Bone biopsies some six months after the Camelford incident from two individuals who drank the contaminated water showed increased aluminium staining in bone formed at a time compatible with exposure but normal bone aluminium concentrations overall, suggesting increased aluminium absorption and retention following acute ingestion without apparent adverse sequelae (Eastwood et al, 1990). Neuropsychological toxicity Aluminium sulphate is widely used in water purification. This source has in the past contributed to aluminium toxicity in haemodialysis patients (see below) and may be involved in the pathogenesis of Alzheimer's disease via accumulation of aluminium in the brain but this remains a highly contentious issue (Ebrahim, 1989; Petit, 1989; Murray et al, 1991; Crapper McLachlan, 1994; Munoz, 1994). Martyn et al (1989) and Neri and Hewitt (1991) reported a geographical relationship between Alzheimer's disease and the concentration of aluminium in drinking water but Wood et al (1988) found no significant difference in mental test score between hip fracture patients living in high versus low water aluminium areas. Animal studies have demonstrated the ability of aluminium to induce the formation of neurofibrillary tangles (Klatzo et al, 1965), impair the learning ability of rats, and increase brain acetylcholinesterase activity in a similar way to that seen in Alzheimer's disease (Bilkei-Gorzó, 1993). Other workers have shown elevated aluminium concentrations in brain tissue from patients with Alzheimer's disease (Crapper et al, 1973) and laser microprobe studies have demonstrated aluminium accumulation in the neurofibrillary tangles of these patients (Good et al, 1992). Harrington et al (1994) described Alzheimer's-disease-like pathological changes in the brains of renal dialysis patients in association with aluminium accumulation without clinical evidence of dialysis encephalopathy (see below). INJECTION Neuropsychological toxicity 'Dialysis dementia' involves the accumulation of aluminium, mainly in the brain, in patients on haemodialysis where the dialysis water contains significant amounts of aluminium sulphate (McDermott et al, 1978). This should now be avoidable by reverse osmosis or deionization of dialysis water prior to use. Peritoneal dialysis solutions and haemofiltration and plasma exchange substitution fluids also may contain excessive aluminium although the incidence of toxicity from these preparations is small (Mion, 1985; Mousson et al, 1989). Elliott et al (1978a) reported a significant correlation between serum aluminium concentrations and the concentrations of aluminium in the water supply in eight patients on home dialysis with cases of dialysis dementia confined to regions with high water aluminium concentrations (>350 µg/L). A larger study (Registration Committee of the European Dialysis and Transplant Association, 1980) of patients treated in 65 dialysis centres in Europe in 1976 and 1977 identified 150 cases of dialysis dementia with a clear association between the occurrence of dementia and dialysis with water which was not treated by deionization or reverse osmosis. Only 23 of 150 patients were still alive in 1978. Similar findings were reported by on et al (1982). Although the problem of aluminium contamination of dialysates has reduced in recent years, these patients may still accumulate aluminium via oral aluminium hydroxide given as a phosphate binder (Salusky et al, 1991). The contribution this makes to dialysis dementia is likely to be small (McDermott et al, 1978; Registration Committee of the European Dialysis and Transplant Association, 1980). It has been suggested (Hodge et al, 1981) that to ensure no aluminium uptake by dialysis patients, the dialysate aluminium concentration should not exceed 14 µg/L. This corresponds to a maximum aluminium concentration in the water supply of 5 µg/L since aluminium is present in significant quantity in the dialysate concentrate (Hodge et al, 1981). The WHO recommended maximum aluminium concentration in drinking water is 200 µg/L (WHO, 1993). Dialysis dementia is progressive and often fatal (Alfrey et al, 1976; Burks et al, 1976). In a review of 412 dialysis patients admitted to one renal unit since 1972, Garret et al (1988) described 38 cases. The mean time between onset of regular dialysis and development of symptoms was 40 months with speech difficulties, seizures and myoclonus the most common presenting features. Dyspraxia, involuntary movements, poor concentration, loss of short-term memory, confusion, depression and anxiety were also described and only nine patients were still alive at the conclusion of the study (Garret et al, 1988). The neurological consequences of aluminium intoxication may be exacerbated in patients with aluminium bone disease who sustain fractures, probably via increased bone aluminium mobilization (Davenport and Ahmad, 1988). There are reports of impaired cerebral function in haemodialysis patients who have an increased body burden of aluminium but no evidence of " dialysis dementia " (Altmann et al, 1989; Bolla et al, 1992). Altmann et al (1989) found significant abnormalities of psychomotor function in 27 long-term haemodialysis patients who had only mildly raised serum aluminium concentrations (mean 59 ± (SEM) 9 µg/L, normal < 10 µg/L). In another study, 23 haemodialysis patients accidentally exposed to aluminium for up to six months following failure of a reverse osmosis system had a mean serum aluminium concentration of 147.3 ± (SEM) 11.7 µg/L without apparent neuropsychiatric sequelae (Caramelo et al, 1995). Bone toxicity In patients with renal failure aluminium toxicity may contribute to renal osteodystrophy (Goyer et al, 1994). In a survey conducted by the European Dialysis and Transplant Association, 102 of 150 patients with dialysis dementia also had evidence of bone disease (Registration Committee of the European Dialysis and Transplant Association, 1980). Parkinson et al (1979) demonstrated a significant correlation (p = 0.01) between the mean aluminium content of the water supply and the incidence of fracturing dialysis osteodystrophy in 1293 patients undergoing intermittent haemodialysis and Ward et al (1978) reported significantly fewer cases of osteomalacia in patients maintained on regular haemodialysis in Newcastle when the dialysate water was deionised. Another study (Chan et al, 1990) found that the incidence of osteomalacic fractures in dialysis patients could not be explained by the aluminium concentration in dialysate alone and a significant contribution by oral aluminium hydroxide was suggested. Aluminium associated osteomalacic osteodystrophy is progressive and characterized by bone pain, a proximal myopathy and spontaneous fractures. In a review of skeletal surveys of 67 patients with end-stage renal failure Garrett et al (1986) found that moderate or severe fracturing osteodystrophy with greater than five fractures had a diagnostic specificity for aluminium intoxication of 100 per cent, provided trauma could be excluded. Investigations typically show normal or only slightly increased alkaline phosphatase activity, normal serum calcium and normal or slightly high serum phosphate concentrations with reduced circulating parathyroid hormone and increased bone and serum aluminium concentrations (Winship, 1992). It is resistant to treatment with vitamin D but improvement may follow desferrioxamine therapy as discussed below. Cardiovascular toxicity Elliott et al (1978b) proposed aluminium induced cardiotoxity (via inhibition of magnesium and ATP-dependent enzymes) as a contributing factor in the sudden death of five dialysis patients, four with dialysis encephalopathy and one non-encephalopathic patient whose serum aluminium concentration was 600 µg/L. Haemotoxicity Aluminium intoxication may exacerbate the microcytic hypochromic anaemia of chronic renal failure via impaired iron utilization (Caramelo et al, 1995). This effect is at least partly reversible with desferrioxamine therapy as discussed below. Dermal toxicity Brown et al (1992) suggested aluminium overload as the cause of a widespread pruritic nodular rash (prurigo nodularis) in three patients on maintenance haemodialysis. The serum aluminium concentration, measured in two patients, was normal but complete resolution occurred in all cases following weekly treatment for some three months with one gram intravenous desferrioxamine. Injection Most cases of aluminium intoxication following aluminium sulphate exposure occur in renal dialysis patients exposed to either intravenous or intraperitoneal aluminium-containing dialysates. The oral administration of aluminium containing phosphate binders may exacerbate aluminium accumulation in these circumstances. Antidotes There is some evidence that parenteral desferrioxamine therapy slows the rate of cognitive deterioration in patients with Alzheimer's disease (Crapper McLachlan et al, 1991; Crapper McLachlan et al, 1993) but further studies are required. Desferrioxamine and dialysis encephalopathy McCarthy et al (1990) treated 28 dialysis patients suffering from aluminium toxicity with long-term (mean 11.0 months) intravenous desferrioxamine, initially at a mean dose of 41.7 mg/kg body weight once weekly, increasing to a maximum dose of 60 mg/kg as tolerated. After five to seven months of treatment serum aluminium concentrations decreased from a mean of 401 µg/L to 245 µg/L. Four patients, who had advanced dementia before treatment, died during the study period. With desferrioxamine treatment seven of 28 patients showed neurological improvement and 25 patients showed improved or stable muscle strength and overall functional capacity. The authors concluded that whilst long-term desferrioxamine therapy can be important in the treatment of patients with significant aluminium exposure it should be employed only when symptoms demand treatment and when patients can be monitored regularly for desferrioxamine toxicity (McCarthy et al, 1990). In 71 dialysis patients D'Haese et al (1990) demonstrated that a serum aluminium concentration of 60 µg/L or greater identified aluminium-related bone disease with 82 per cent sensitivity and 86 per cent specificity. However, Gilli et al (1983) suggested serum aluminium concentrations were unlikely to reflect total aluminium accumulation in uraemic patients and Seyfert et al (1987) suggested plasma aluminium concentrations were not reliable in the diagnosis of aluminium-related bone disease. This author emphasised the importance of bone biopsy as the definitive investigation for aluminium osteomalacia and advocated the 'desferrioxamine test' as a useful diagnostic tool.
