The main industrial solvent described in superfund sites in the south bay is TCE (trichloroethelyine), which does not bioaccumulate. The fruit won't contain it

The main industrial solvent described in superfund sites in the south bay is TCE (trichloroethelyine), which does not bioaccumulate. The fruit won't contain it, even if you live right on the superfund site.
I'm not aware of a major soil contaminant around here that does bioaccumulate. I guess lead from the old leaded gasoline, which we stopped using in the 1970s. (Areas around roads that were active prior to the 1970s will have higher soil lead levels). But that's the same as any place in the US.

- derekp7 9y agoI think mid to mid-late 70's was when most cars could no longer take leaded gasoline (the pump nozzle wouldn't fit, and catalytic converters would get plugged). Leaded gas was still available, but as older cars died not much leaded gas was pumped (cars back then didn't have as long of a life cycle, so probably by 85 or so more cars than not were on unleaded).
- inferiorhuman 9y agoYou started to see smog equipment in '75 but initially not everyone used catalytic converters. Some, like BMW and Mazda, used thermal reactors. Leaded fuel was common enough that part of the smog check was to ensure that a leaded nozzle couldn't fit.
