| 英文摘要 | Mercury contamination in aquatic environments is of worldwide concern because of its high biomagnification factor in food chains and long-range transport. The rivers, estuary and the bay along the northwestern Bohai Sea coast, northeastern China have been heavily contaminated by Hg due to long-term Zn smelting and chlor-alkali production. This work investigated the distributions of total Hg (THg) and smonomethylmercury (MMHg) in the water, sediment and hydrophytes from this area. Concentrations of THg in sediment (0.5-64 mg kg(-1)) and water (39-2700 ng L-1) were elevated by 1-3 orders of magnitude compared to background concentrations, which induced high concentrations of MMHg in these media. The highest concentration of MMHg in sediment reached 35 mu g kg-1. which was comparable to that in the Hg mining area, Wanshan, China, and the highest MMHg concentration of 3.0 ng L-1 in the water sample exceeded the MMHg Chinese drinking water guideline of 1.0 ng L-1. Concentrations of THg in a sediment profile from Jinzhou Bay were found to be consistent with annual Hg emission flux from a local Zn smelter (r = 0.74, p < 0.01), indicating that Hg contamination was mainly caused by Zn smelting locally. For some freshwater hydrophytes, concentrations of THg and MMHg ranged from 5.2 to 100 mu g kg(-1) and 0.15 to 12 mu g kg(-1), respectively. Compared to sediment, concentrations of THg in hydrophytes were 2-3 orders of magnitude lower but MMHg was comparable or higher, indicating that the bioaccumulation in plants was distinct for the two Hg species studied. The data suggest that a significant load of Hg has been released into the northwestern coastal region of the Bohai Sea. (C) 2009 Elsevier Ltd. All rights reserved. |
