UK waters are too polluted to swim in, but European countries offer answers
Almost all of the UK's waterways are polluted. In 2022, a House of Commons Committee report on the state of UK rivers concluded that no river in England was free from chemical contamination. Only 14% of UK rivers had a "good" ecological status......»»
Chemical reactions on the early Earth may have formed its ocean
Conditions that favor water may be common in the formation of rocky planets. Enlarge (credit: NASA/NOAA/GSFC/Suomi NPP/VIIRS/Norman Kuring) Water has made the Earth the planet that it is—a planet known for its blue oce.....»»
How groundwater can be efficiently freed from pollutants such as glyphosate
Contaminated drinking water poses a major threat to our health. However, various pollutants such as pesticides, herbicides, hormones, medicines and other chemical compounds cannot be completely removed from groundwater with the methods currently avai.....»»
To fight cancer, EPA wants sterilizer companies to emit less
The Environmental Protection Agency on Tuesday proposed limiting the use of the chemical ethylene oxide after finding a higher than expected cancer risk at facilities that use it to sterilize billions of medical devices each year......»»
