    Chlorine harms marine life – and we don’t even need it

    Even in tiny amounts, chlorine is highly toxic to fish and other aquatic life. Trout larvae die at concentrations as low as 0.006 mg/L, and at just 0.1 mg/L, most marine plankton are killed. Once released, chlorine can also react with organic matter in seawater to form trihalomethanes (THMs) – a group of persistent, carcinogenic… Read more
