The use of tetrasul has been banned in Europe since 2003[1].
Tetrasul has a low water solubility (0.03 mg/l) and is very hydrophobic. It therefore is very likely to adsorb to particles and the sediment and to have a high potential towards bioaccumulation.
Tetrasul becomes toxic for fishes at concentrations above 11 mg/l. As a substance witch bioaccumulates and possibly also biomagnifies there may be risk to marine mammals by secondary poisoning. Mammals which consume more than 3,9 g per kilogram of body weight might be affected. Chronic exposure might cause effects at lower dosesCite error: Invalid <ref> tag;
