    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.

    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.
