High levels of pollution found in many of the world’s major cities are having negative effects on plants and insects, according to new research from the University of Sheffield.

Geographers from the National University of Singapore (NUS) have found that coastal vegetation such as mangroves, seagrasses, and salt marshes may be the most effective habitats to mitigate carbon emissions.

Outdoor air pollution is a major health threat worldwide. New CHHS research found that exposure to certain air pollutants is linked to increased emergency department (ED) visits for respiratory and cardiovascular diseases.

A warmer, drier climate is expected is increase the likelihood of larger-scale forest disturbances such as wildfires, insect outbreaks, disease and drought, according to a new study co-authored by a Portland State University professor.

Sixty-nine pharmaceutical compounds have been detected in stream insects, some at concentrations that may threaten animals that feed on them, such as trout and platypus. When these insects emerge as flying adults, they can pass drugs to spiders, birds, bats, and other streamside foragers. These findings by an international team of researchers were published today in Nature Communications.

Some of the most useful and versatile materials today are the metal-organic frameworks (MOFs). MOFs are a class of materials demonstrating structural versatility, high porosity, fascinating optical and electronic properties, all of which makes them promising candidates for a variety of applications, including gas capture and separation, sensors, and photocatalysis.

Yale researchers have found that a type of air pollution is much more complicated than previous studies indicated.

Mercury is an incredibly stubborn toxin. Once it is emitted from the smokestacks of coal-fired power plants, among other sources, the gas can drift through the atmosphere for up to a year before settling into oceans and lakes. It can then accumulate in fish as toxic methylmercury, and eventually harm the people who consume the fish.

A new study of the Deepwater Horizon response showed that massive quantities of chemically engineered dispersants injected at the wellhead—roughly 1,500 meters (4,921 feet) beneath the surface—were unrelated to the formation of the massive Deepwater oil plume.

During the record-breaking 2018 fire season, the typically clear waters of Cameron Falls in Waterton Lakes National Park in southern Alberta flowed black.
