Pollution from Asia is causing ozone levels to rise above the western United States, an increase that could make it more difficult for the U.S. to meet Clean Air Act standards for ozone pollution at ground level, according to an international study published on Wednesday. The study, published in the journal Nature, analyzed large sets of ozone data captured since 1984. It focused primarily on data for ozone in springtime above western North America at an altitude of between two and five...

Researchers in Freiburg have developed a highly-sensitive, miniaturized mobile ozone sensor which can be used not only in air, but also in water and in the vicinity of explosive gases. The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg is developing improved chemical sensors that are not prohibitively expensive. One particularly important area of application involves the regular measurement of ozone content in air and other media. This gas is a powerful oxidizing agent...

Australian scientists have announced the world's first successful large-scale restoration of a coastal wetland being devastated by acid runoff. A dramatic improvement in environmental conditions has been achieved by researchers working on the trial Hills Creek catchment at the East Trinity site near Cairns in Queensland, using a combination of natural tidal action and strategic treatment with lime. Mangrove and wetlands are returning, birdlife is flocking to the area and fish abound in creeks...

Even the snow on Aconcagua Mountain in the Andes is polluted with PCBs. An international team of researchers detected low concentrations of these toxic, carcinogenic chlorine compounds in samples taken from America's highest mountain. The snow samples taken at an altitude of 6200 meters are among the highest traces found anywhere in the world of these substances, which have been banned since 2001. In particular, the samples contained more persistent compounds like hexachlorobiphenyl (PCB 138)...

The bane of every good housekeeper's existence is that relentless, untiring foe known as dust.  Researchers now say they have created a computer model that may help us to understand where it all comes from and why we can never seem to get rid of it. In most homes, scientists say that the majority of dust sneaks in through the air from outdoors and is composed of a variety of offensive ingredients such as dead skin cells, soil and even toxic substances that drift in from contaminated...

Understanding phosphorus cycling is essential for managing modern wetlands Phosphorus is an essential element in production agriculture, however fertilizer runoff and wastewater discharge have led to massive eutrophication problems in water bodies worldwide. Many researchers believe such contamination is at least partly responsible for offshore "dead zones," such as the expansive area found in the Gulf of Mexico. While wetlands often act as filtering or storage systems for nutrients,...

Today's soil contamination is a direct result of man-made chemicals or other changes in nature's soil environment. This contamination most commonly occurs from underground storage tanks bursting, use of pesticides, discarding oil and fuel illegally, leakage of dirty surface water, draining of wastes from landfalls and knowingly dumping industrial wastes into the soil. The most widespread chemicals found are petroleum hydrocarbons, solvents, common pesticides, lead and additional heavy metals....

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
