That is a LOT! That explains the frequency of red areas on the map. What a shame.
Here in BC it's a similar story with the ocean and dioxins from industrial effluents. You can't harvest shellfish around most of southern Vancouver Island. It seems like everyone has a story of poisoning their own food and water.

Looking closer, the north seems to be mostly mercury pollution (at least inland), and the south seems to be varying sources (chlordane, dieldrin, PCB, DDT).
- steve_adams_86 7y agoAh, okay then. Coincidentally I clicked around and mostly saw mercury and a couple seleniums, so it seemed like mercury was the biggest issue. I wonder what the others are caused by... I'm guessing industrial effluents.
