A geochemical survey of the northwestern part of the Thailand Gulf (Inner Gulf) was carried out in order to define concentrations and distribution patterns of selected heavy metals (V, Cr, Co, Ni, Cu, Zn, and U) in the coastal system and estuarine area of the Mae Klong river. The results indicate the presence of two different sources of heavy metals in the studied environment and allowed us to identify a lithogenic component that significantly influences the composition of coastal waters and suspended particulate matter (SPM). Comparison of the normalized heavy metals concentrations both in the studied samples and in those reported for the Sn-W ores present in the surrounding areas suggests an important anthropogenic contribution to the chemistry of the seafloor sediments. Vanadium and nickel enrichment factors (EF) calculated for coastal waters indicate that contamination by hydrocarbons discharge took place in the investigated area.
为了确定泰国湾西北部（内湾）沿海系统和湄公河河口地区选定重金属（钒、铬、钴、镍、铜、锌和铀）的浓度及分布模式，开展了一项地球化学调查。结果表明，研究环境中存在两种不同的重金属来源，这使我们能够识别出一种对沿海水域和悬浮颗粒物（SPM）成分有重大影响的岩成组分。将研究样本中的重金属浓度与周边地区锡钨矿报告中的浓度进行归一化比较，结果表明人为因素对海底沉积物的化学性质有重要影响。为沿海水域计算的钒和镍富集因子（EF）表明，研究区域存在烃类排放污染。
