The maximum immission doses (MID) for molybdenum are intended to protect livestock raised on pastures or in animal houses. The limits are based on results of feeding experiments with farm animals raised for use. In these experiments the animals received fodder to which sodium or ammonium molybdate was added or whose content of sodium or ammonium molybdate was urally high or was increased by ambient air pollution.
