The gas is hazardous, being one of the most toxic compound of selenium and far more toxic than its congener hydrogen sulfide. The threshold limit value is 0.*5 ppm. At high concentrations even exposure for less than a minute causes the gas to attack the eyes and mucous membranes causing cold-like symptoms for at least a few days afterwards. In Germany, the limit in drinking water is 0.**8 mg/L, and the US EPA recommends a maximum contamination of 0.*1 mg/L.
