Recent research from the University of Alberta reveals that contrary to current scientific knowledge, there's no atmospheric lead pollution in the province's oil sands region.
Industrial sites and highways could become cleaner in the future thanks to shark-shaped samplers that hunt ‘fugitive’ air pollutants.
Scientists have long known that air pollution caused by cars and trucks, solvent use and even plants, is reduced when broken down by naturally occurring compounds that act like detergents of the atmosphere. What has not been well understood until now are the relative contributions of all the processes producing such compounds.
China's demand for Environmental Pollution Control Equipment has grown at a fast pace in the past decade. In the next decade, both production and demand will continue to grow. The Chinese economy maintains a high speed growth which has been stimulated by the consecutive increases of industrial output, import & export, consumer consumption and capital investment for over two decades.
Anglers across the nation wondering why luck at their favorite fishing spot seems to have dried up may have a surprising culprit: a mine miles away, even in a different state.
Researchers from the UPM have characterized the health risks derived from the usage of mercury in artisanal gold mining in Colombia through probabilistic models.
In recent years, many lakes in the upper Midwest have been experiencing unprecedented algae blooms. These blooms threaten fish and affect recreational activities. A key culprit implicated in overgrowth of algae in lakes is phosphorus (P). Lake Pepin, located on the Minnesota/Wisconsin border, has seen increasing phosphorus concentrations over time. Researchers are now trying to identify upstream factors that could explain this increase.
Prenatal exposure to polycyclic aromatic hydrocarbons, or PAH, a component of air pollution, raises the odds of behavior problems associated with attention deficit hyperactivity disorder, or ADHD, at age 9, according to researchers at the Columbia Center for Children's Environmental Health at the Mailman School of Public Health. Results are published online in the journal PLOS ONE.
Even during summer dry spells, some isolated patches of soil in forested watersheds remain waterlogged. These patches act as hot spots of microbial activity that remove nitrogen from groundwater and return it to the atmosphere, researchers from several institutions, including Virginia Tech, report in a leading scientific journal.
Targeting emissions of non-CO2 gases and air pollutants with climate effects might produce smaller benefits for long-term climate change than previously estimated, according to a new integrated study of the potential of air pollution and carbon dioxide mitigation.
