Anthropogenic sulphur inputs

Sulphur-containing petroleum components such as benzothiophene, DBT, and naphthobenzothiophene were obtained from seawater extracts (Warner, 1975) and were related to an oil spill. The detection of diphenyl sulphone and bis-(p-chlorphenyl) sulphone in ng amounts in the Mediterranean, as well as in oxic and anoxic Baltic waters, suggests anthropogenic input (Bouchertall, 1979) — the former compound is used as wood preserving agent and ovicide.
