Yeah gherk, that's the same piece Streets cut and pasted the other day. The author has a definite ax to grind so has slanted the piece to fit his agenda. A more rational assessment of lead danger, and probably what has since contributed to lower levels of lead in humans, would include the paint on one's house. While airborne lead from auto fuel was definitely an issue, atmospheric conditions would "flush" the contaminant, whereas in the house it tended to "stay" more. And even with traffic considerations, folks spend more time in their houses than their cars.
