Reducing chlorine disinfection can make swimming pools safer ANI | Updated: Feb 17, 2021 23:12 IST
Washington [US], February 17 (ANI): A new study by the American Chemical Society, has found that using complementary forms of disinfection, like copper-silver ionization (CSI), can decrease disinfection byproducts and cell toxicity of chlorinated swimming pool water.
Swimming in indoor or outdoor pools is a healthy form of exercise and recreation for many people. However, the findings published in ACS Environmental Science & Technology have linked compounds that arise from chlorine disinfection of the pools to respiratory problems, including asthma, in avid swimmers.
Disinfecting swimming pool water is necessary to inactivate harmful pathogens. Although an effective disinfectant, chlorine can react with organic matter and compounds introduced by swimmers, such as those in sweat, urine, sunscreens, and cosmetics, to produce disinfection byprodu

UNIVERSITY PARK, Pa. The economic value of insect pollinators was $34 billion in the U.S. in 2012, much higher than previously thought, according to researchers at the University of Pittsburgh and Penn State. The team also found that areas that are economically most reliant on insect pollinators are the same areas where pollinator habitat and forage quality are poor.

“Pollinators like bees play an extremely important role in agriculture,” explained senior author Vikas Khanna, Wellington C. Carl Faculty Fellow and associate professor of civil and environmental engineering at Pitt’s Swanson School of Engineering. “The insects that pollinate farmers’ crops underpin our ecosystem biodiversity and function, human nutrition, and even economic welfare.”

Urban agriculture in Chicago does not allow consumers to rely solely on local food
Environmental Science & Technology
Environmentally conscious consumers try to “buy local” when food shopping. Now, a study of food raised around Chicago has shown that buying local can’t provide all necessary nutrients for area residents, though it could fulfill their needs if some nutrients were supplied as supplements. The researchers report in ACS’ Environmental Science & Technology that urban agriculture made little difference in reducing overall land area, and thus distance, required to supply all nutritional needs.
As the U.S. population continues to flow to urban regions, consumers are moving farther from farms and croplands. This limits nutrient recycling and drives up emissions associated with transporting food. In addition, urban centers can develop “food deserts” where residents can’t purchase nutritious food close to home. One potential solution is urban agricult
