Remember the victory scored this week by the Obama Administration on mercury emissions?
This "very big deal" just got bigger.
The EPA's official analysis of the impact of mercury on kids' brains is limited to the impact on wages of children born to families that catch freshwater fish for their own consumption. The impact they find is, not surprisingly, pretty small since most families don't each much self-caught freshwater fish. But the entire analysis simply skips the impact of mercury toxins ingested through commercial fishing which, obviously, is the vast majority of the fish that people eat.
They did it this way because it's extremely difficult to trace oceanic mercury to specific power plants and because the rule (easily) passes cost-benefit scrutiny for separate reasons so there was no need for the EPA to produce a guesstimate about it. But a 2005 study that attempted to quantify this estimated $8.7 billion per year in lost wages wages due to mercury-related IQ loss. There is huge potential low-hanging fruit here to build an entire better next generation of Americans, but this entire subject was completely excluded from the EPA's analysis which is overwhelmingly focused on the respiratory impact of particulate inhalation. That's a big deal. It means less asthma, thousands fewer premature deaths from older people, etc. But the main channel through which mercury does neurological damage to infants and fetuses is basically neglected for technical reasons.
To be clear -- the new rules will invariable affect all fish, but the EPA's benefit analysis only calculated for fish caught in freshwater environments because it's nearly impossible to trace the mercury found in commercially-caught fish to any specific source. Meaning the benefits of the new rules have been vastly underestimated.
