Airports’ leaden fallout may taint some kids
People who live below the flight path of piston-engine aircraft — or downwind of airports serving such small planes — are exposed to lead from aviation fuel. A new study now links an airport’s proximity to somewhat elevated blood-lead levels in children from area homes.

Long-term effects of early exposure to hydrocarbons remains unknown.

Young minds at risk from secondhand smoke
Children exposed to secondhand smoke at home are at least twice as likely to develop a neurobehavioral disorder as are kids in smokefree homes, a new study finds. And roughly 6 percent of U.S. children — some 4.8 million — encounter smoke at home.

Metal water bottles may leach BPA
Consumers who switched from polycarbonate-plastic water bottles to metal ones in hopes of avoiding the risk that bisphenol A will leach into their beverages aren’t necessarily any better off, a new study finds. Some metal water bottles leach even more BPA — an estrogen-mimicking pollutant — than do ones made from the now-pariah plastic.

Some comfort about broken CFLs
My night-owl daughter woke me in a panic at around 2 a.m., a couple of weeks back. While swatting at a fly, she’d just broken the compact fluorescent light illuminating her closet. Having heard me warn endlessly of how we should be careful in handling these bulbs — since they contain mercury — she wanted to know what kind of damage control was called for. I only wish I knew then what I do now.
