Chemicals 400 times as mutagenic as known carcinogens found
from Environment News Service
From Jan. 9:
Newly identified compounds produced by chemical reactions in vehicle exhaust or by grilling meat are hundreds of times more mutagenic than their cancer-causing parent compounds, according to scientists at Oregon State and three other universities. These compounds were not previously known to exist, and they raise concerns about the health impacts of heavily-polluted urban air and dietary exposure, the researchers said. It is not yet clear in what amounts the compounds might be present, and no health standards now exist for them.
