V 1988 max. povolená hodnota denního přídělu rtuti snížena na 6 mikrogramů/den

Scientists have debated the health effects of low levels of mercury for years. The U.S. Environmental Protection Agency (U.S. EPA) has proposed slashing the amount of mercury it considers safe to ingest from 30 micrograms ([[micro]gram]) per day - the limit recommended by the World Health Organization and the federal Agency for Toxic Substances and Disease Registry - to just 6 [[micro]gram] per day. To follow the new guidelines, FDA would have to take off the market a significant proportion of the fish now available, especially large predatory fish like swordfish, shark, and red snapper. The guideline could even affect tuna.
