According to ecotoxicologist from Far Eastern Federal University (FEFU), from the '90s and during 2000s in the tissues of Russian Far Eastern mussels the concentration of organochlorine pesticides (OCPs) that had been globally used in agriculture in the mid-20th century has increased about 10 times. OCPs pollute and affect badly the ecosystems of the Sea of Japan, the Sea of Okhotsk, and the Bering Sea. A related review was published in Water Research.
If the fatty fish we eat were free of environmental pollutants, it would reduce our risk of developing type 2 diabetes. However, the pollutants in the fish have the opposite effect and appears to eliminate the protective effect from fatty fish intake. This has been shown by researchers at Chalmers University of Technology in Sweden, using innovative methods that could be used to address several questions about food and health in future studies.
A new study from UC San Francisco suggests that a protein found in the common bullfrog may one day be used to detect and neutralize a poisonous compound produced by red tides and other harmful algal blooms. The discovery comes as these waterborne toxic events are becoming increasingly common, a consequence of climate change making the world's oceans more hospitable to the microbes responsible for these formerly infrequent flare-ups.
Combining research-oriented teaching and interdisciplinary collaboration pays off: researchers at the University of Konstanz develop a novel spectroscopic approach to investigate hitherto difficult-to-observe protein structures. On 'campus.kn,' the online magazine of the University of Konstanz, we report on the new approach and its origin at the interface between chemistry and biology.
The common perception that pesticides reduce or eliminate target insect species may not always hold. Jennifer Weathered and Edd Hammill report that the impacts of agricultural pesticides on assemblages of aquatic insects varied resulting in distinct ecological winners and losers within aquatic communities.
New findings of a multi-university research team show the pesticide DDT persists in remote lakes at concerning levels half a century after it was banned, affecting key aquatic species and potentially entire lake food webs.
To control pest outbreaks, airplanes sprayed more than 6,280 tons of dichlorodiphenyltrichloroethane (DDT) onto forests in New Brunswick, Canada, between 1952 and 1968, according to Environment Canada. By 1970, growing awareness of the harmful effects of DDT on wildlife led to curtailed use of the insecticide in the area. However, researchers reporting in ACS' Environmental Science & Technology have shown that DDT lingers in sediments from New Brunswick lakes, where it could alter zooplankton communities.
A new study by Imperial Brands, owners of leading vape brand blu, contributes to the increasing evidence base substantiating vaping's harm reduction potential compared to smoking. The research, presented at the 58th annual meeting of the Society of Toxicology earlier this year, compared the in-vitro toxicological responses of a 3D model of human lung tissue to myblu vapour and cigarette smoke across a range of biological endpoints.
Nitrate pollution of US drinking water may cause up to 12,594 cases of cancer a year, according to a new peer-reviewed study by the Environmental Working Group.
The sea water, beaches and sediments on the Tarragona coast contain quantities of plastic similar to those in a big city like Barcelona. And more than half are clothing fibres from washing machines. This is one of the main findings of a study carried out by researchers from the URV's research group Tecnatox and presented at a congress in Helsinki.
