In the mid-2000s a survey was conducted to evaluate fish mercury in lakes across New York State. Approximately 10 years later a second survey examining adult sportfish from 103 lakes and reservoirs was conducted to evaluate the response of fish mercury to recent declines in US mercury emissions. Of those lakes, 43 were part of the earlier survey and were examined to determine if mercury concentrations in four popular sport species, Yellow Perch, Walleye, and Small- and Largemouth Bass, declined in response to decreasing emissions. Water samples were also collected at 35 of these lakes and analyzed for mercury, methylmercury and other analytes. The Adirondack and Catskill regions remain biological mercury hotspots with elevated concentrations in fish. The most widely sampled species, Yellow Perch, showed significant increases in mercury in the Northeast and West regions of New York State over the past decade. The increases in Yellow Perch mercury is not consistent with significant reductions in water concentrations of both total and methylmercury observed corresponding in lake water samples. This discrepancy suggests watershed and in-lake processes beyond mercury emissions, such as recovery from acid deposition, impacts from climate change, or changes in food web structure may be controlling fish mercury concentrations. These results demonstrate a need for a consistent, long-term program to monitor fish mercury to inform the status of mercury contamination in New York State.

在2000年代中期，进行了一项调查，以评估纽约州各湖中鱼的汞含量。大约10年后，进行了第二次调查，调查了103个湖泊和水库中的成年运动鱼，以评估鱼汞对近期美国汞排放量下降的响应。在这些湖泊中，有43个是早先调查的一部分，并进行了检查以确定四种流行的运动物种，即黄鲈，角膜白斑鱼和小口鲈和大口鲈鱼中的汞浓度是否随着排放量的减少而下降。还从这些湖泊中的35个收集了水样，并对其中的汞，甲基汞和其他分析物进行了分析。阿迪朗达克（Adirondack）和卡茨基尔（Catskill）地区仍然是生物汞热点，鱼类中的汞浓度较高。采样最广泛的物种，黄鲈，在过去十年中，纽约州东北和西部地区的汞含量显着增加。Yellow Perch汞的增加与在湖水样品中观察到的总汞和甲基汞的水含量显着降低并不一致。这种差异表明，超出汞排放量的分水岭和湖内过程，例如酸沉降的恢复，气候变化的影响或食物网结构的变化，可能正在控制鱼类的汞浓度。这些结果表明，需要一个一致的长期计划来监测鱼的汞含量，以告知纽约州汞污染的状况。Yellow Perch汞的增加与在湖水样品中观察到的总汞和甲基汞的水含量显着降低并不一致。这种差异表明，超出汞排放范围的分水岭和湖内过程，例如酸沉降的恢复，气候变化的影响或食物网结构的变化，可能正在控制鱼类的汞浓度。这些结果表明，需要一个一致的长期计划来监测鱼的汞含量，以告知纽约州汞污染的状况。Yellow Perch汞的增加与在湖水样品中观察到的总汞和甲基汞的水含量显着降低并不一致。这种差异表明，超出汞排放量的分水岭和湖内过程，例如酸沉降的恢复，气候变化的影响或食物网结构的变化，可能正在控制鱼类的汞浓度。这些结果表明，需要一个一致的长期计划来监测鱼的汞含量，以告知纽约州汞污染的状况。或食物网结构的变化可能正在控制鱼的汞浓度。这些结果表明，需要一个一致的长期计划来监测鱼的汞含量，以告知纽约州汞污染的状况。或食物网结构的变化可能正在控制鱼的汞浓度。这些结果表明，需要一个一致的长期计划来监测鱼的汞含量，以告知纽约州汞污染的状况。
