 Untreated wastewater "Regularly released into rivers in the UK" is building microplastic hotspots on riverside beds.That was the conclusion of a Greater Manchester study that revealed that high concentrations of plastics were immediately used in the treatment process.The team behind the research concluded that untreated wastewater is a "significant source" of plastic pollution.The water company that runs the river where the scientists study said it was not "fully accepted" with the findings.But the scientists who published their research in the journal Nature Sustainability A peer-reviewed study said overflowing drains and outflows from treatment plants could release millions of plastic particles in a day.
Professor Jamie Woodward, lead researcher at the University of slotxo เวอร์ชั่นล่าสุด Manchester,that at the most contaminated area in the Tame River, where the study team found there were "More than 130,000 microplastic particles per kilogram of river sediment"Therefore, for every gram of the sludge, there are 130 particles, which are exceptionally high levels of contamination.It is clear that wastewater is the main source of microplastics in our rivers.While water company United Utilities declined to be interviewed, Jo Harrison, the company's environmental director, said in a statement: "We understand that wastewater is a contributing factor to microplastics' pollution. We took part in the study. Two years broader Starting this summer ... to understand the source and consequences of microplastics in the environment.
A spokesman for the Environment Agency, which controls the activities of the water industry, added that the agency was "Helping the water industry research in this area"Water companies are allowed to release untreated wastewater when pipes in their plants are exposed to too much rainwater. But researchers say they measure plastic buildup in the dry summer.To generate high levels of contamination, [they] have to drop wastewater into low-flow areas, so when there is no heavy rain,It almost became a routine for many water companies to do this."A report by the Environment Agency released earlier this year appears to confirm the conclusion, revealing that water companies release 400,000 raw sewage into UK rivers in 2020 and a recent study using artificial intelligence to Detected sewage leak showed that hundreds of other releases were not recorded, not reported.Commenting on the latest study, Professor Andrew Johnson,
from the UK Center for Ecology and Hydrology (CEH) in Wallingford, said wastewater from the sewer was overflowing. But he added "We should not be ignorant of running away from roads and fields adjacent to all kinds of rivers.And the Water UK water industry says "Prevention is better than cure". "People can participate too by not flushing wet wipes and other single-use plastic items in the toilet," the spokesperson said.Microplastics are bound by rivers, the foundation of river ecosystems, so researchers are concerned that the pollution accumulates where it is most likely to be harmful, said Dr Rachel Hurley of the Norwegian Water Research Institute. That the impact of microplastic pollution on rivers is a global concern.A lot of wastewater is untreated around the world," she said, "and we know this wastewater combines many types of microplastics in one place."We need to find out what the real causes of these wastewater discharges are.
