摘要: In this study, the Hg distributions in water and sediments from a mangrove creek that receives intensive shrimp farming effluents were determined. The average dissolved particulate concentrations varied 3.1 to 9.2 ng L−1 4.4 9.4 L−1, respectively. However, suspended matter bottom 95.4 115.7 g−1 1.6 10.3 g−1, A Ward quadratic distance cluster analysis based on hydro- geochemical parameters (oxygen, salinity, temperature, pH, organic aluminum content) showed effects of distribution pattern. Furthermore, these results supported by sediment cores. This study emphasizes necessity including as potential pollutant when monitoring environmental impacts farming.
