What part of the Movhave Desert did he grow up in?

There was a lot of toxic and radio-active dumping done in that area and certain areas a still classified as "hot zones"

Dumping on the chromium dump

Nicholson

More than 100 years ago a company in Glasgow, Scotland, dumped 10,000 tons of chromium waste in an old clay pit. There it lies still, with football pitches above it and housing estates all around. But the local authorities, worried by reports that the active ingredient in the dump - chrome 6 - could be carcinogenic, have brought in a chemical clean-up agency from the US called Dames & to advise them.

'Stick horse manure in it!' they were told. In technical terms, the aim is to change the hexavalent chromium to trivalent chromium or chrome 3, which is far less toxic. To do this, one approach was to use a natural non-proprietary reducing agent such as iron sulphate or ammonium sulphate, together with nutrients to help along the process. In the end this should produce hydrogen sulphide, biologically created by bugs, which is a natural reducing agent. "We looked at things like manure and molasses which would have two impacts," said Rowley of Dames & . "They would be a nutrient to the bugs and they make the area anaerobic; so it de facto becomes a reducing environment and the hydrogen sulphide these bugs produce can act as the reducing material. This helped create the environment where the chrome would be reduced to its relatively innocuous and stable form." So now you know.
