    It’s in the rain and every freshwater fish or lake water has it, such that even once per year fish consumption is not recommended. Safe level is 4.4ng per kg body weight/week. 300ng for adult male. Half kilo of fish will be 4800ng. Technically that is 3 fish portions per year, but you will get enough smaller amounts every day to breech limit with freshwater fish.

    You have a point that it may still be needed for some stuff.
