A study of seven wastewater treatment plants in the Eastern United States points to two treatment methods -- granular activated carbon and ozonation -- as particularly promising. Each technique reduced the concentration of a number of pharmaceuticals, including certain antidepressants and antibiotics, in water by more than 95%, the scientists' analysis found.
Metal particles from the abrasion of brake pads -- up to a fifth of fine particulate matter (PM2.5) air pollution at roadsides -- may cause inflammation and reduce the ability of immune cells to kill bacteria a new study has found, similarly to particles derived from diesel exhaust. The scientists say this suggests that particulate pollution from brake wear could be contributing to increased susceptibility to airway infections and other negative effects on respiratory health.
NASA's Terra satellite provided before and after imagery that showed the extent of the fires that have been ravaging Australia's Kangaroo Island. Kangaroo Island lies off the mainland of South Australia, southwest of Adelaide.
Private well owners should test water quality annually, according to a recent Kansas State University study that revealed nitrate levels in shallow wells above US Environment Protection Act standards.
Children who grow up in areas with heavy air pollution have a higher risk of developing schizophrenia. This is the conclusion of a new study from the Danish psychiatry project, iPSYCH.
The decommissioning of coal-fired power plants in the continental United States has reduced nearby pollution and its negative impacts on human health and crop yields, according to a new University of California San Diego study.
It's no secret that many insects are struggling worldwide. But we could fix these insects' problems, according to more than 70 scientists from 21 countries. Their road map to insect conservation and recovery is published in Nature Ecology & Evolution this week. From urgent 'no-regret' solutions to long-term global comparisons.
A new study estimated the nitrogen deposition in northern China through a combination of remote sensing data and atmospheric chemical transport model simulations.
Field trials in Oregon and Arizona show that poplar trees, which emit trace amounts of the gas isoprene, can be genetically modified not to harm air quality while leaving their growth potential unchanged.
Field trials in the Northwest and Southwest show that poplar trees can be genetically modified to reduce negative impacts on air quality while leaving their growth potential virtually unchanged.
