Thirdhand smoke is created when exhaled smoke and smoke emanating from the tip of burning cigarettes settles on surfaces such as clothing, hair, furniture, and cars. A team led by scientists at the University of California, Riverside, has found chemicals in THS get extracted more readily from household fabrics in a humid environment than in a dry one.
Researchers at Duke University have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block. The technique could be a boon for finding and mitigating sources of hazardous aerosols, studying the effects of air pollution on human health, and making better informed, socially just public policy decisions.
Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.
Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from discarded plastics.
The map shows a near-present snapshot of effects from deforestation, mining, expanding road networks, urbanization and increasing agriculture.
University at Buffalo engineers report a new process of 3D printing graphene aerogels that they say overcomes two key hurdles -- scalability and creating a version of the material that's stable enough for repeated use -- for water treatment.
Patients who have preexisting respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD) and live in areas with high levels of air pollution have a greater chance of hospitalization if they contract COVID-19, says a University of Cincinnati researcher.
One consequence of the coronavirus pandemic has been global restrictions on mobility. This, in turn, has had an effect on pollution levels in the atmosphere. Researchers from across the world are using this unique opportunity to take measurements, collect data, and publish studies. An international team led by Forschungszentrum Jülich's Institute of Climate and Energy Research - Troposphere has now published a comprehensive review providing an overview of results up to September 2020.
International scientists from around the world are warning that chemical pollutants in the environment have the potential to alter animal and human behaviour. A scientific forum of 30 experts formed a united agreement of concern about chemical pollutants and set up a roadmap to help protect the environment from behaviour altering chemicals.
Wastewater carries large quantities of organic substances into the rivers and lakes, leading to heavy growth of bacteria and oxygen deficiency. Measurement methods have so far been incapable of measuring this organic pollution precisely. A new method co-developed by experts from the Helmholtz-Zentrum Hereon should provide a clear image of the water conditions in the future. The work has now been published in the scientific journal Science Advances.
