Hydrocarbons on oil-stained Samet higher than normal


BANGKOK, 25 August 2013 Deputy Dean of the Faculty of Fisheries, Kasetsart University, Dr. Thon Thamrong-nawasawat, points out that hydrocarbon levels in some areas on the oil spill-affected Samet island are higher than a safe limit. Hydrocarbons might result in a lower egg laying rate of marine animals. 

On 24 August 2013, Dr. Thon announced the results of Samet island environmental surveys conducted by the university after the oil spill incident last month. He said the surveys showed that hydrocarbon amounts in some areas were higher than normal levels due to the oil spill. The academic suggested that continuous monitoring of Ao Phrao beach, where the oil spill had directly hit, was necessary.

As for mercury in sediment on the seabed, Dr. Thon said mercury levels at many beaches were within a safe limit. He confirmed seafood from Samet was safe to consume, citing the studies by the Department of Fisheries and Chulalongkorn University as indicating that there was no residue in marine animals.

However, Dr. Thon added that such findings did not mean the oil spill had not caused any problems. High amounts of hydrocarbons might affect offspring of sea animals and their egg production. Further studies were needed at least for the next 6-12 months, the deputy dean said.
