Thailand has taken part in the IGOSS Marine Pollution
Monitoring (Petroleum) Programme (MAPMOPP)
since 1976. In 1983, dissolved petroleum
hydrocarbons in seawater, sediments, and certain species
of bivalves and fish were measured, using the
spectrofluorometric method with chrysene as a standard,
following the methodology set out by the Intergovernmental
Oceanographic Commission. The results
are shown in Table 8.
