We have known for years that outbreak pollution was one of the main reasons for the decrease in the quality of some of our greatest fresh water resources. Thank God , Certain legislation and a friend of the environment All over the world began to turn the tide.
A A recent study The American Chemical Society has claimed that it reveals the most influential pollutants that contributed to the low levels of biological diversity in freshwater.
A team of researchers from UK Center for Environment and Hydrology He mentioned that zinc and copper greatly influenced the diversity of invertebrates in fresh water for years. The team collected data throughout 1989 to 2018 from 1457 invertebrate monitoring sites in England. Then they used what they call “41 chemical, physical and geographical and geographical variables to run their analysis.
The study concluded that it did not find any other variables that were “more consistent and strongly linked” with the number of items – or the unit of the classification of living organisms – than zinc and copper. With the decrease in zinc and copper quantities in fresh water sites, the levels of biological diversity increased.
Andrew Johnson, an environmental research scientist at UKCEH and co -author, believes that the general screaming has strongly contributed to reducing zinc and copper. However, there is one slight difficulty in developing new policies.
Johnson spoke to Phys.org Regarding the data from the study: “There is a widespread desire by the public to improve water quality and biological diversity in our rivers, but the problem of policy makers is likely to achieve the steps.
“Our study provides strong evidence that zinc and copper concentrations have the greatest influence on the richness of invertebrate species, so it is unlikely that the fruits of biological diversity in fresh water without other discounts in these minerals will come.”
According to the study, Directing urban wastewater treatment for the European Union It is likely that it plays a pivotal role in reducing pollution in fresh water sources. However, the researchers say that “the discounts are in Infection in the atmosphere Associated with the end of coal burning “may also be a major factor.
The biological diversity of freshwater is vital for Sustainability From our food chain. Many ecosystems of fresh water affect water cleaning and excessive nutrient filtering, pathogens, and pollutants.
Johnson Duplicate To data from long -term studies that enables “wildlife itself to speak directly to us.
