Polluted Water from Thailand Floods a Threat to Marine Life

Posted on 11/15/11 No Comments The Nation has an interesting story, Polluted water a threat to Gulf sea-life, that discusses how the salinity of the sea in the Gulf of Thailand has changed due to the flooding in Thailand. Experts expect a number of western coast the areas in the Gulf of Thailand to be effected by the pollution, Samut Songkhram's Don Hoi Lot, Phetchaburi, Prachuap Khiri Khan and Chumphon. Gulf of Thailand marine life such as Bruda whales and Irrawaddy dolphins may be indirectly affected due to changes in the food chain as sea catfish and squid are expected to occur. Map of the Gulf of Thailand In the Pattaya area, salinity level of the "upper sea" in Chon Buri's Koh Khangkao and Koh Sichang was down to 4 parts per thousand while the lower sea was at 23 parts per thousand. The salinity of the sea the distribution of plants and animals that live in the ocean. In addition, marine salinity affects other seawater properties such as water density and the amount of dissolved oxygen. As a point of reference, the average salinity of the world’s oceans is 35 parts per thousand. Freshwater has a salinity of less than 1 parts per thousand. Brackish inshore waters have salinity values between 1 - 25 parts per thousand; and waters with salinity greater than 40 parts per thousand are called hypersaline. Globally marine pollution in not limited to land-based flooding and includes a wide range of threats oil spills, untreated sewage, heavy siltation, eutrophication (nutrient enrichment), invasive marine species, persistent organic pollutants, heavy metals, acidification, radioactive substances, marine litter, overfishing and destruction of coastal and marine habitats.
