Lack of observed impacts of gas production of Bongkot field, Thailand on marine biota

The impact of metal releases, associated with gas production, on biota in the Lower Gulf of Thailand was evaluated based on metal concentrations in finfish and on the composition of sediment fauna. Results indicate that metal concentrations, particularly Hg, in species of snapper and grouper collected near the gas production platform were not significantly different from those of the same species of fish caught from the regional, presumably non-impacted, fishery. Also, there were no significant differenc- es in faunal communities in sediments collected near petroleum production activities from those in sediments collected at remote sites.
