In the law of the European Union,<unk> s, more exactly<unk>  occupational exposure<unk>  values (IOELVs), are human exposure<unk> s to hazardous substances specified by the Council of the European Union based on expert research and advice. They are not binding on member states but must be taken into consideration in setting national occupational exposure<unk> s. Some member states have pre-existing national<unk> s lower than the IOELV and are not required to revise these upwards. In practice, most member states adopt the IOELV but there are some variances upwards and downwards.
