Low doses of Mercury Changes the Way the Arteries Work

[Guest guest]

"

Data confirm that low doses of mercury have a harmful effect on vascular

function. Mercedes Salaices, one of the other authors of the study,

emphasises that the impact of mercury “could be compared to the impact

produced by other more traditional cardiovascular risk factors such as

hypertension, diabetes or hypercholesterolaemia”. "

The risk of exposure to mercury today

Humans have been exposed to different metal pollutants such as

mercury, although the possible consequences to health are not known in

depth. At the present time, exposure to mercury is due, mainly, to the

consumption of polluted fish, to the administration

of anti-fungal agents and Thimerosal antiseptics in vaccines and to the

inhalation of mercury vapour from some dental re-constructions[

amalgam(mercury) fillings].

Exposure To Low Doses Of Mercury Changes The Way The Arteries

WorkScienceDaily (Oct. 27, 2008) ­ An international team of

researchers has shown that mercury is another important factor in

cardiovascular disease as it changes the way arteries work. One of the

possible sources of exposure of humans to mercury is by eating

contaminated fish.

The main effects of mercury affect the central nervous system and renal

function. Over recent years the scientific community has reported an

increase in cardiovascular risk following exposure to mercury, “although

the mechanisms responsible for this increase are not completely known”,

state the authors of the new study that has been published recently in

the American Journal of Physiology-Heart and Circulatory Physiology

explain.

Ana María Briones is a researcher at the Universidad Autónoma of Madrid

(UAM) and is one of the authors of the study. Briones explains the aim of

the investigation to SINC: “Because the relationship between mercury and

cardiovascular risk has been explained recently, and that cardiovascular

risk is known to be related to changes in vascular function, we intended

to see whether a relationship existed between mercury and changes in

vascular responses”.

The aim of the study was to evaluate whether really low concentrations of

mercury, administered over a prolonged period of time, “could have a

prejudicial effect on vascular response”, that is to say, on the way the

arteries behave.

Data confirm that low doses of mercury have a harmful effect on vascular

function. Mercedes Salaices, one of the other authors of the study,

emphasises that the impact of mercury “could be compared to the impact

produced by other more traditional cardiovascular risk factors such as

hypertension, diabetes or hypercholesterolaemia”.

The researchers analysed whether chronic exposure to mercury causes an

endothelial dysfunction in resistance and conductance arteries. Treatment

with mercury induces an increase in oxidative stress, which is

responsible – at least in part – for the deterioration in vascular

responses. “Arteries contract more and relax less because there is less

nitric oxide”, the vasodilator factor that is attacked by oxidative

stress, underlines Briones.

The risk of exposure to mercury today

The European Environment Agency (EEA) recommended a reference blood

mercury concentration of 5.8 nanograms per milliliter (ng/ml). It is

considered that there are no adverse effects below this level. Data

reveal that the concentration of mercury in the general population is

less than 1 ng/ml, whereas in workers who suffer exposure in polluted

zones, the levels are between 7 and 10. The percentage reaches up to 5.6

ng/ml amongst people who eat fish on a regular basis.
