Major breakthrough could help detoxify pollutants
Scientists at The University of Manchester hope a major breakthrough could lead to more effective methods for detoxifying dangerous pollutants like PCBs and dioxins. The result is a culmination of 15 years of research and has been published in Nature. It details how certain organisms manage to lower the toxicity of pollutants. (2014-10-19)

A new material capable of the adsorption of organic pollutants in water
The results show that the material C18-Mica-4 is capable of eliminating the majority of pollutants that were evaluated in urban waste water, as well as surface water and potable water. The study, also, provides data on the adsorption mechanism and establishes a significant correlation between the physical chemical properties of the selected criteria and emerging pollutants and the adsorption to the material.

Glacial melting may release pollutants in the environment
Those pristine-looking Alpine glaciers now melting as global warming sets in may explain the mysterious increase in persistent organic pollutants in sediment from certain lakes since the 1990s, despite decreased use of those compounds in pesticides, electric equipment, paints and other products. That's the conclusion of a new study, scheduled for the Nov. 1 issue of ACS' Environmental Science & Technology, a semimonthly journal. (2009-10-21)

Asian Industrial Smog: It's Increasingly Blowing In The Wind Across The U.S. West Coast
It seems that Americans are not entirely to blame for the chemical smog that hangs over cities along the U.S. West Coast. A new study indicates that about 10 percent of the ozone and other pollutants are arriving from the industrialized nations of East Asia. After measuring pollutants from a remote Olympic Peninsula research station, a researcher concludes that Asian pollution is affecting much of the U.S.West Coast, with Washington and Oregon affected slightly more because of wind patterns.

Cell death in porpoises caused by environmental pollutants
Environmental pollutants threaten the health of marine mammals. This study established a novel cell-based assay using the fibroblasts of a finless porpoise stranded along the coast of the Seto Inland Sea, Japan, to better understand the cytotoxicity and the impacts of environmental pollutants on the porpoise population. The results revealed that the concentrations of PCBs and DDTs which accumulated in the porpoise are likely to have an adverse effect at the cellular level. (2020-07-20)

Persistent Organic Pollutants, The Danger Is Not Over
Despite substantially reduced emissions of most well known persistent organic pollutants, e.g. PCBs and dioxins, the danger is far from over. The toxic substances are still present in the environment and in our bodies. Moreover, a number of similar pollutants have recently been discovered in the environment, according to the Swedish Environmental Protection Agency. (1998-08-18)

Treaty to limit CO2 should be followed by similar limits on other greenhouse pollutants
While carbon dioxide is the main greenhouse gas and the focus of climate treaties, other pollutants that stay in the atmosphere for only days or months also contribute to global warming. UC Berkeley Ph.D. candidate Stacy Jackson argues in Science that policymakers should plan a summit now to look at these pollutants, which range from soot to ozone and methane, because they will be more complicated to regulate than is the case with carbon dioxide.

More male fish 'feminized' by pollution on the Basque coast
Members of the Cell Biology in Environmental Toxicology group have discovered evidence of 'feminization' of male fish in the estuaries of Gernika, Arriluze, Santurtzi, Plentzia, Ondarroa, Deba and Pasaia. The first cases -- 2007-2008 -- were detected in Urdaibai, and the most recent data confirm that they are also taking place in other estuaries. Pollutants acting as estrogens are responsible for this phenomenon which, among other changes, is causing ovocytes to appear in male fish. (2014-03-28)

Black carbon -- a major climate pollutant -- also linked to cardiovascular health

Organic sunscreens released to natural waters potentially cause negative effects to aquatic organisms or humans after long-term exposure. These pollutants may undergo transformation under sunlight to form unknown compounds. In a paper published recently by Chinese Science Bulletin, the latest research progresses on photochemical transformation kinetics, products, and photoinduced toxicity of widely used organic sunscreens were introduced. The authors aimed to trigger scientific interests and public concerns on organic sunscreen pollutants. (2013-12-17)

Melting snow contains a toxic cocktail of pollutants
With spring finally here and warmer temperatures just around the corner, snow will slowly melt away, releasing us from the clutches of winter. However, that's not the only thing that the melting snow will release. Researchers from McGill University and École de technologie supérieure in Montreal have found that urban snow accumulates a toxic cocktail from car emissions - pollutants that are in turn unleashed into the environment as the weather warms up.

Chicago lake breeze effect could increase asthma risk
Chicago has long been known as one of the nation's worst cities for asthma sufferers. Scientists have confirmed that the familiar lake breeze effect that moves air pollution back and forth between the city and Lake Michigan may expose residents to high concentrations of hazardous substances. Initial city pollutants react with each other over Lake Michigan, generating more toxic compounds that then move back toward the city. (2003-06-01)

Water-treatment plants are not supposed to harm the functioning of river ecosystems
When a river receives waste water from a treatment plant, the plant's efficiency is revealed. A UPV/EHU research group, in collaboration with the ICRA institute of Girona, has observed that the waste water from treatment plants significantly influences the river ecosystem. As the quantity of organic matter is bigger, the activity of the organisms that feed on it increases. Yet other organisms are harmed because this matter contains toxic substances. (2015-10-29)

Experts call for cleaner air to tackle invisible killer
