Sure. Knowing is half the battle, and this is the sort of thing that could be attacked on a local level. That's a really persuasive article. I'll spin it by my biologist and see what he says. Would be good to investigate the research a little. But I like that. It's practical. At a glance the data looks good and clean, and it appears to be reproducible. If it turns out to be true you could, I think, start a testing program by putting out a smattering of collectors around town to sample airborne lead levels at the driest parts of the year. Even as few as a hundred would give you some insight. Once you've identified the worst affected areas go in and make sure you know the sources there and begin a targeted remediation program, yard by yard, block by block, neighborhood by neighborhood. And if for ten years you hit the worst affected neighborhoods every year you'll make a difference. While you're at it introduce some basic incentives for careful window replacement. People might even jump at that and chip in some of their own money, as it will help you save on heating bills. This one need only be an incentive, not a full blown program. Yes, there is hope. Good read.
