EPA Launches Community Engagement Efforts on New Ethylene Oxide Risk Information
The US Environmental Protection Agency (EPA) just announced its plans to engage and inform communities, states, Tribes, Territories, and stakeholders about up-to-date information on the risks posed by air emissions of ethylene oxide (EtO) from commercial sterilizers, as well as EPA’s efforts to address these risks. EPA is releasing new information on specific facilities where lifetime risk levels are the highest to people who live nearby and is encouraging impacted communities to participate in a series of public engagements to learn more. Later this year, EPA expects to propose an air pollution regulation to protect public health by addressing EtO emissions at commercial sterilizers.

Lead and Crime: It's a Brain Thing
When I wrote my big piece last year about the connection between childhood exposure to lead and rates of violent crime later in life, one of the big pushbacks came from folks who are skeptical of econometric studies. Sure, the level of lead exposure over time looks like an inverted U, and so does the national rate of violent crime. But hey: correlation is not causation.
I actually addressed this in my piece—twice, I think—but I always felt like I didn't address it quite clearly enough. The article spent so much time up front explaining the statistical correlations that it made the subsequent points about other evidence seem a bit like hasty bolt-ons, put there mainly to check off a box against  For that reason, I'm pleased to recommend Lauren Wolf's "The Crimes Of Lead," in the current issue of Chemical & Engineering News. It doesn't ignore the statistical evidence, but it focuses primarily on the physiological evidence that implicates lead with higher levels of violent crime: Research has shown that lead exposure does indeed make lab animals—rodents, monkeys, even cats—more prone to aggression. But establishing biological plausibility for the lead-crime argument hasn’t been as clear-cut for molecular-level studies of the brain. Lead wreaks a lot of havoc on the central nervous system. So pinpointing one—or even a few—molecular switches by... |

Evacuation Zone Expanded in NJ Toxic Train Derailment
The US Coast Guard has expanded the evacuation zone in Paulsboro NJ (Gloucester County) following the toxic derailment of a train carrying deadly cancer causing vinyl chloride. Evacuations have been mandatory since last Friday when a movable bridge failed to function and collapsed when a freight train was moving over it.
The National Transportation Safety Administration (NTSB) is co-ordinating an intensive accident investigation. The NTSB reported yesterday that the bridge had problem and that the train engineer contacted a Conrail dispatcher for authorization to cross the bridge even though the bridge signal was red indicating bridge trouble. The NTSB also reported that the bridge was inspected by two Conrail supervisors shortly before the event because of trouble signal being sent by the bridge safety mechanism.
