A team of University of California, Riverside’s Bourns College of Engineering students created a roof tile coating that when applied to an average-sized residential roof breaks down the same amount of smog-causing nitrogen oxides per year as a car driven 11,000 miles.
During two days of intensive airborne measurements, oil and gas operations in Colorado's Front Range leaked nearly three times as much methane, a greenhouse gas, as predicted based on inventory estimates, and seven times as much benzene, a regulated air toxic.
Rising temperatures in the United States could result in a 70 percent increase in unhealthy summertime ozone levels by the year 2050.

Over four decades ago, acid rain caused by industrial emissions was eradicating fish and dissolving stone monuments in the Eastern US. However, emissions of sulfur dioxide and nitrogen dioxide, both of which cause acid rain, dropped significantly after the passing of the Clean Air Act of 1970.
Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze.
