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.

Methane is a climate pollutant that leads to the production of ozone with serious health and environmental impacts

The Taklamakan Desert, one of the major sources of background Asian dust, is situated in the Tarim Basin, with the Tianshan Mountains in the north, Pamir Plateau in the west, and Kunlun Mountains in the south. Dunhuang (40°00？N, 94°30？E; 1146 m above sea level) is located in the east of the Taklamakan Desert, China. The area is significant for studying the initial state of Asian dust particle transportation, which is mainly influenced by westerly winds.

Scientists at Indiana University found high levels of a previously unsuspected pollutant in homes, in an electronic waste recycling facility and in the natural environment. People are likely to be exposed to this pollutant by breathing contaminated dust or through skin contact.

Every day around 93% of the world’s children under the age of 15 years (1.8 billion children) breathe air that is so polluted it puts their health and development at serious risk. Tragically, many of them die: WHO estimates that in 2016, 600,000 children died from acute lower respiratory infections caused by polluted air.

Three Mount Allison University professors and several students will be taking a closer look at microplastics in the Saint John River watershed.

Removing the troublesome impurities of hydrogen sulfide (H2S) and carbon dioxide (CO2) from natural gas could become simpler and more effective using a metal-organic framework (MOF) developed at KAUST.

Cleaning up or replacing coal-fired power plants that lack sulfur pollution controls could help Texans breathe cleaner, healthier air, according to researchers at Rice University.
