Lead is the most prevalent heavy metal contaminant. [24] As a component of tetraethyl lead, (CH 3 CH 2) 4 Pb, it was used extensively in gasoline during the 1930s–1970s. [25] Lead levels in the aquatic environments of industrialised societies have been estimated to be two to three times those of pre-industrial levels. [26]
