contamination

Purity is usually associated with ideas about cleanliness, sanctity or avoiding contamination – so finding that it is associated with negative views about wealth gives new meaning to the phrase “filthy rich.”

In a new paper, Harvard researchers argue for a stricter lead soil contamination standard in California.

However, the researchers detected infectious H5N1 virus after 120 days of aging at 39 degrees Fahrenheit, suggesting that the standard aging period may not fully eliminate viral contamination.

Similar side effects could result from artificial sulfate releases, including acid rain and soil contamination.

This could have given modern humans a significant evolutionary advantage over Neanderthals, even in the presence of lead contamination.
