A warming Earth could mean stronger toxins : Nature News
Global warming might change the level of toxicity of current toxins by making them more available in nature reports Richard Lovett from Nature News. Here are some of the pathways involved:
… melting sea ice in the Arctic Ocean exposes more seawater to the atmosphere, which may make it easier for toxic chemicals in arctic waters to escape into the air.
…climate change will cause differences in the movement, quality and distribution of water that could affect stream acidity all over the world […] Drugs are designed so that small changes in acidity alter their bioavailability, helping to route them to the bodily tissues where they are needed.
