beskrivelse:
Lead in trees' bark , and in air in South-Africa
Now with the ban or reduction of lead in motor fuels in most countries, the level of lead in air has decreased significantly. But it may remain trapped in the wood of trees, and then poison the insects or birds or bats insectivorous. Cook food on wood that drove near a major thoroughfare is a possible source of food contamination by lead (barbecue grills ...). The smoke from the firewood will be another possible source of air pollution
