太湖水体微囊藻毒素变化及其与理化因子的关系
Variation of Microcystins in Water Body of Taihu Lake and Its Relationship with Physicochemical Factors
摘要
Abstract
Water samples were collected at three sampling sites in the Taihu Lake from May to October in 2009, and the physico-chemical factors and microcystin ( MC) content were determined. In the whole sampling period, the extracellular MC content varied from ND ( not detected, < 0. 02 μg/L) to 0. 67 μg/L at three sites, and only MC - RR and MC - LR were detected in extracellular MC. Intracellular MC content varied from ND to 53. 34 (μg/L at three sites, and MC - RR and MC - LR were the predominant MC species. As many as six MC species in the water body at the site No. 2 were detected in October, 2009. The CODMn and chlorophyll - a content had significantly positive correlations with intracellular MC content at three sampling sites. The correlations of extracellular and intracellular MC contents with the physicochemical parameters were not consistent among different sampling sites. Different assessments of environmental influence should be made on extracellular and intracellular MC contents according to different districts of the Tailu Lake.关键词
