ความเข้มข้นของปรอทรวมในเนื้อเยื้อชนิดต่างๆ ของปลาทะเลบางชนิดที่อาศัยอยู่ในบริเวณแท่นผลิตก๊าซธรรมชาติในอ่าวไทย / พิมพร เจริญศรี = Total mercury concentrations in different tissues of marine fishes inhabitated around the natural gas production platforms in the Gulf of Thailand / Pimporn Charoensri
The mercury concentrations in muscle tissues, liver and kidney samples of three marine fishes : snapper (Lutjanus argentimaculatus Forsskal), dusky jack (Caranx sexfasciatus Quoy & Gaimard) and chub (Kyphosus cinerascens Forsskal) inhabitated around the natural gas platforms in the Gulf of Thailand and Pranburi coastal area in Prachuabkhirikhan province were studied during January to April 2001. Mercury analysis was conducted using cold vapor atomic absorption technique. The study showed that type of tissues had some relationships with mercury accumulation. Mercury accumulation in liver and kidney was higher than muscle tissues. The positive correlations between mercury concentrations and types of tissue were found in snappers and dusky jack. Type of fishes were related with mercury accumulaion. Mercury concentrations in dusky jack muscle tissues and liver were significantly higher than those of snapper and chub (p<0.05). Snapper kidney mercury concentrations was significantly higher than dusky jack and chub. (p<0.05). The mercury concentrations in muscle tissues, liver and kidney in snapper and dusky jack inhabitated around the natural gas platforms had a tendency to higher than those inhabitated in Pranburi coastal area, but there was no statistical significant. The positive correlations between mercury concentrations and the length size of these three species inhabitated in both area were found.
