12.DNuclear power is the world's largest source of clean energy.Nuclear power plants(电厂) produce no controlled air pollutants,such as sulfur or greenhouse gases.The use of nuclear power in place of other energy sources helps to keep the air clean,preserve the earth's climate,and prevent ...
Article Open access 19 April 2022 Decline in bulk deposition of air pollutants in China lags behind reductions in emissions Article 21 February 2022 IntroductionChina and India are the top two consumers of coal in the world1. Coal typically contains a few percent of sulfur by weight, and it...
Using a whole-watershed approach and a combination of historical, contemporary, modeled and paleolimnological datasets, we show that the High Arctic’s largest lake by volume (Lake Hazen) has succumbed to climate warming with only a ~1 °C relative increase in summer air temperatures. This wa...
The Candiota region, located in the extreme south of Brazil, has the largest mineral coal deposit in the country, and this activity is capable of releasing pollutants in which they are associated with the contamination of different matrices (soil, water, and air). The present study aimed to ...
High aerosol amounts include particulate matter (PM2.5 and PM10) among other pollutants as well as sea salt, dust, black and organic carbon. Primary aerosols like dust, soot, or sea salt, come directly from the planet’s surface. They get lifted into the atmosphere by gusty winds, shot hi...
Endogenous nutrients released from sediments are a potential hazardous source in aquatic ecosystems, especially reservoirs. Here, we investigated seasonal and spatial variations of different species of nitrogen and phosphorus and evaluated the pollution levels of nutrients in sediments from one of the world...
The environmental damage has led to serious health problems for residents of the five countries around the Caspian Sea, who ingest pollutants through air, drinking water, food and swimming. According to the Pars Times, Caspian-area Kazakhstan sees four times the rate of blood diseases, tuberculosis...
The continued downstream transport of the mine tailings accumulated along the Rio Doce basin will serve as a long-term source of Mn and other trace metals, and potentially maintain the continued bioaccumulation risks of Mn into the estuary. Therefore, chronic Mn contamination is expected to persist...
Another category of atmospheric pollutants of which you might not be aware is the particulate aerosol emitted into the atmosphere by the progressive wear of vehicle parts, especially synthetic rubber tyres, during their service life. Separately from this, however, there are also heavier pollutants fro...
Wastewaters contain large amounts of nitrogen, phosphorous, and potassium. Using water twice—once for municipal use and once for irrigation use—converts would-be pollutants into valuable fertilizers while protecting rivers and lakes from contamination and providing a local source of water supply. ...
