Hazardous chemicals such as bromine, antimony and lead are finding their way into food-contact items and other everyday products because manufacturers are using recycled electrical equipment as a source of black plastic, according to a new study.

Rising property values in Vancouver have resulted in the demolition of an unprecedented number of single-family homes in recent years, many of which were replaced with the same type of structure.

The annual federal report on toxic material emissions from industrial sites across the country gains widespread media attention and serves as a reminder of the potential environmental impacts of industrial activities.

The main type of “bunker” oil for ships is heavy fuel oil, derived as a residue from crude oil distillation. Crude oil contains sulphur which, following combustion in the engine, ends up in ship emissions. Sulphur oxides (SO_x) are known to be harmful to human health, causing respiratory symptoms and lung disease. In the atmosphere, SO_x can lead to acid rain, which can harm crops, forests and aquatic species, and contributes to the acidification of the oceans.

Limiting SO_x emissions from ships will improve air quality and protects the environment.

A new University of Guelph study has discovered why exposure to pesticides increases some people’s risk of developing Parkinson’s disease.

Smog is a problem. But the knowledge about its constituents – no longer. Researchers from several leading Warsaw scientific institutions have joined forces and developed a new, extremely precise method for the chemical analysis of suspended particulate matter. The method, easily adaptable in many modern laboratories, not only determines the chemical composition of compounds, but even recognizes changes in the spatial distribution of atoms in molecules.

Shuttering coal- and oil-fired power plants lowers the rate of preterm births in neighboring communities and improves fertility, according to two new University of California, Berkeley, studies.

Water pitchers designed to rid water of harmful contaminants are not created equal, new research has found.

Chlorofluorocarbons, or CFCs, were once considered a triumph of modern chemistry. Stable and versatile, these chemicals were used in hundreds of products, from military systems to the ubiquitous can of hairspray.

Ecologists have long known that agricultural and sewage pollution can cause low oxygen conditions and fish kills in rivers. A study published today in Nature Communications reports that hippo waste can have a similar effect in Africa’s Mara River, which passes through the world renowned Maasai Mara National Reserve of Kenya, home to more than 4,000 hippos.
