Chonburi, July 30- The Department of Marine and Coastal Resources hastened to inspect the sea water quality around Koh Lan. Chonburi Province that turns green was found to be caused by the phenomenon “Plankton Bloom” is a major cause of wastewater discharge into the sea. Iterates rapidly growing phytoplankton now. Does not create toxins but will continue to monitor the water situation
Mr. Apichai Ekwanakul, Deputy Director-General of the Department of Marine and Coastal Resources Acting Director General of the Department of Marine and Coastal Resources said Instructed the Marine and Coastal Resources Research Center in the Eastern Gulf of Thailand (SVAT) to speed up the inspection of sea water quality in the area of Koh Lan. Chonburi Province As soon as you know that sea water changes color The results of the investigation found that the sea water changed color and smelled bad in 5 areas, namely the maritime route between Koh Lan - South Pattaya, Koh Sak, and in the area of Koh Lan, namely Na Ban Beach, Ta Waen Beach and Thian Beach.
From the initial water quality measurement Their values were temperature 30.1-31.2 °C, salinity 30.9-31.8 ppt (ppm), acidity and alkali 8.16-8.31, and dissolved oxygen 4.20-7.69 mg/l. Which is in the sea water quality standard type 4 for recreation without affecting aquatic animals
Mr. Apichai said that this changing sea water phenomenon is called "Plankton bloom" or "whale excrement" is a natural phenomenon that occurs 2-3 days in a year, which is not harmful to aquatic animals and people who swim in the sea. The main cause of the phenomenon is the release of wastewater into the sea. often occurs during the rainy season If the rain continues and there are waves and strong winds for several days will wash the nutrients in the ground along the coast into the sea Until causing plankton to get nutrients and grow rapidly From the classification of plankton that bloom in the sea water is Phytoplankton in the family of dinoflagellates, Noctiluca scintillans, which do not produce toxins.
When the oxygen in seawater is depleted The plankton will die until the sea water turns into different colors such as brown, red, green or black.
At the same time, I would like to give a message to the people. tourist and the fishermen said Do not release or dump waste into the river.
