In Lake Baiyangdian, the largest lake in the North China Plain, a team of researchers found a potentially dangerous levels of mercury and arsenic. This is a surprising finding, because this place is a source of both food and drinking water for the people who live around it.
After studied three separate locations in this lake, researchers found concentrations of arsenic and mercury in fish were above the threshold considered by the U.S. Environmental Protection Agency (EPA) to pose a risk to humans and wildlife.
Of course this research associated to Chinese people along this lake. Scientist still learn how these two toxic environmental metals moved through the food web in a freshwater ecosystem. Then the researchers found that more nutrient-rich environments supported larger algal blooms, which resulted in lower concentrations of mercury and arsenic in the water due to uptake by the algae. When there is a lot of algae present, mercury and arsenic are biodiluted, or more dispersed, so zooplankton that eat the algae are exposed to lower levels of the metals and transfer less to fish.
