High levels of ground-level ozone have been found to severely impact the growth of ozone-sensitive crops on Long Island, including spinach, grapes, pumpkins, watermelons, and tomatoes. This research highlights the urgent need for attention to be paid to ambient ozone levels in agricultural areas.
Ground-level ozone levels are high enough to reduce growth and yield of sensitive plants on Long Island, where important agriculture is located. White clover has been particularly affected, with a 24-27% reduction in growth rate.
Researchers create molecular-level studies of pollutant-catalyst interactions using X-ray diffraction and neutron scattering techniques. Their findings may lead to improved pollution traps by optimizing catalyst design and surface area.
A recent study published in Science reveals that urban and industrial air pollution can suppress rainfall and snowfall by creating clouds with abnormally small water droplets. This phenomenon occurs when pollution particles act as 'seeding' sites, preventing cloud moisture from condensing into raindrops and ice crystals.
The US Environmental Protection Agency has awarded $8.2 million to the University of Washington for a research center studying air pollution and its effects on human health. The Northwest Research Center will examine fine particles, particulate matter under 2.5 microns in size, and their association with daily health outcomes.
Researchers have found detectable levels of tributyltin in Gulf oysters, which can be toxic to crustaceans. Additionally, the Mississippi River has shown improvement in water quality, with a decrease in volatile organic compounds detected since 20 years ago.
Engineers at Purdue University have developed a training program that instructs workers on techniques to minimize styrene emissions. The program resulted in a 42.4% decrease in emissions, with an additional 19% reduction in the quantity of styrene needed for the job.
A USGS study published in Atmospheric Environment reveals that air in Washington's Mount Rainier National Park contains higher concentrations of ozone than nearby urban areas. This poses a threat to park visitors and the beautiful forests, wetlands, and alpine meadows within the park.
Researchers at University at Buffalo discovered that aerosol clusters can amplify chemical reactions, creating carcinogenic by-products from benign reagents. The study may provide a better understanding of how air pollution forms and inform regulation strategies.
Robert W. Pitz is using advanced laser diagnostics to study gasoline burning characteristics in direct injection engines, aiming to reduce pollutants while maintaining efficiency. His research may lead to the development of next-generation engines with improved fuel economy and reduced emissions.
Researchers at Purdue University have developed a method to measure pollutants produced by combustion, using laser-induced fluorescence. This technique has the potential to significantly reduce nitric oxide production in next-generation jet engines, designed for lean direct injection.
The report highlights the problems caused by nonpoint source pollution, including eutrophication, which can lead to fish kills, coral reef destruction, and shellfish poisoning. The report provides solutions, such as reducing fertilizer applications, improving sewer systems, and restoring wetlands.
An international team of scientists conducted a study on air pollution in Mexico City's basin, where inversions trap pollutants and fine particles pose significant health risks. The study provides insights into particle concentrations, transport patterns, and implications for U.S. cities.
The UW smogmobile generates no emissions and can actually remove pollutants from the air as its fuel is produced. Its efficiency is currently around 20% due to a less-than-ideal motor design, but further development aims to increase range to match gas-powered vehicles.
