The salinity of freshwater ecosystems caused by road de-icing salts, agriculture fertilizers, mining operations and climate change is increasing worldwide and current water quality guidelines don카지노 게임 컬렉션t do enough to address the issue, an international study led by Queen카지노 게임 컬렉션s 카지노게임사이트 and The 카지노게임사이트 of Toledo has found.
The research, conducted in collaboration with dozens of scientists across North America and Europe, shows significant damage is being done to freshwater lakes by salt concentrations that are below ranges government regulators have deemed safe and protective of freshwater organisms.
Using an experimental network of 16 sites in four countries, the research recently published in the Proceedings of the National Academy of Sciences indicates freshwater salinization triggers a massive loss of zooplankton, a major food source for fish, and an increase in algae 카지노 게임 컬렉션 even at the lowest chloride thresholds established in Canada and the U.S. and throughout Europe.
Researchers say the results indicate a major threat to the biodiversity, water quality and functioning of freshwater ecosystems and the urgency for governments to reassess current threshold concentrations to protect lakes from salinization sparked by sodium chloride, one of the most common salt types leading to the salinization of freshwater lakes.
카지노 게임 컬렉션More algae in the water could lead to a reduction in water clarity, which could affect organisms living on the bottom of lakes as well,카지노 게임 컬렉션 said Dr. Shelley Arnott, professor of aquatic ecology at Queen카지노 게임 컬렉션s 카지노게임사이트 and co-leader of the project and paper. 카지노 게임 컬렉션The loss of zooplankton leading to more algae has the potential to alter lake ecosystems in ways that might change the services lakes provide, namely recreational opportunities, drinking water quality and fisheries.카지노 게임 컬렉션
The lowest threshold for chloride concentration in the U.S. established by the Environmental Protection Agency is 230 milligrams of chloride per liter. In Canada, it카지노 게임 컬렉션s 120 milligrams of chloride per liter. Throughout Europe, thresholds are generally higher.
It can take less than a teaspoon to pollute five gallons of water to the point that is harmful for many aquatic organisms.
카지노 게임 컬렉션Salt pollution occurring from human activities such as the use of road de-icing salts is increasing the salinity of freshwater ecosystems to the point that the guidelines designed to protect fresh waters aren카지노 게임 컬렉션t doing their job,카지노 게임 컬렉션 said Dr. Bill Hintz, assistant professor of ecology at The 카지노게임사이트 of Toledo, author of the paper and co-leader of the project. 카지노 게임 컬렉션Our study shows the ecological costs of salinization and illustrates the immediate need to reassess and reduce existing chloride thresholds and to set sound guidelines in countries where they do not exist to protect lakes from salt pollution.카지노 게임 컬렉션
