Silver nanoparticles are increasingly being used in consumer products, such as clothing and personal care products, in the medical and pharmaceutical industry, and in the food industry. That is why their presence is expected to increase in the environment where they can exert harmful effects on organisms. The UPV/EHU's 'Cell Biology in Environmental Toxicology' research group has analysed adult zebrafish to find out the effects that in the long term can be caused by these silver particles present in fresh water.
Air pollution may be linked to a heightened risk of developing dementia, finds a London-based observational study, published in the online journal BMJ Open. The associations found couldn't be explained by factors known to influence the risks of developing the condition, say the researchers.
Ingestion of degrading ocean plastics likely poses a substantial risk to the survival of post-hatchling sea turtles because the particles can lead to blockages and nutritional deficiencies, according to new research.
Inspired by the negative results in the recently published largest-scale analysis of the relation between population density and positions in geographic ranges and environmental niches, a team of US and Mexican scientists identified several issues in the methodology used, able to turn the tables in the ongoing debate. Their findings are published in the innovative open access journal Rethinking Ecology.
Babies exposed to higher levels of organochlorine compounds in the womb go on to have worse lung function in childhood, according to new research presented today (Tuesday) at the European Respiratory Society International Congress. These compounds, which include the pesticide DDT, as well as electrical insulators and other industrial products, are now banned in most parts of the world. However, because they degrade very slowly, they are still present in the environment and in foods.
Since 2010, a tiny moth originating from East Asia has been spreading over eastern North America. Its green larvae, or caterpillars, make narrow tunnels in the leaves of Siberian elms. Sometimes very abundant, they can be seen to descend en masse from the trees when they are done feeding. The moth species was described independently from Russia as Stigmella multispicata in 2014.
Evidence of tiny particles of carbon, typically created by burning fossil fuels, has been found in placentas for the first time, in new research presented today at the European Respiratory Society International Congress.
Soot and dust alters thyroid development in fetuses before they are born in smoggy cities, raising concern about health impacts later in life, new USC research shows. Scientists focused on more than 2,000 kids in smoggy Southern California as part of USC's ongoing Children's Health Study.
The use of coal-based synthetic natural gas, known by the acronym 'SNG,' would increase carbon emissions and water demand, especially in regions in China that already have high per capita carbon emissions and water scarcity, according to a study in Nature Sustainability.
Oysters likely suffered toxic effects from the oil dispersant Corexit® 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill, said Morris Animal Foundation-funded researchers at the University of Connecticut. The team determined this by comparing the low levels of toxicity of oil, the dispersant and a mixture of the two on Eastern oysters. The team published their findings in the journal Aquatic Toxicology.
