The air we breathe and water we drink may be more harmful than we realize according to Carlos Crespo's research teamIs the air we breathe on a daily basis slowly killing us?It may not be that severe, but the air we breathe and water we drink may be more harmful than we realize.Toxic nitro-aromatic pollutants (or nitro-polycyclic aromatic hydrocarbons), both manmade and naturally occurring, continue to be emitted into the air and are present in food, water systems, soils and sediments, says...

Air pollution has both short- and long-term toxic effects that injure the heart and blood vessels, increasing rates of cardiac illness, U.S. researchers say. Dr. Robert A. Kloner of the Heart Institute of the Good Samaritan Hospital and Keck School of Medicine, University of Southern California, both in Los Angeles, said when pollutants are inhaled, they trigger an increase in "reactive oxygen species" -- superoxiding molecules that damage cells, cause inflammation in the lungs and spark...

By Anonymous New evidence that chemical contaminants are finding their way into the deep-sea food web has been found in deep-sea squids and octopods, including the vampire squid. These species are food for many deep-diving toothed whales and other predators. Michael Vecchione of the National Oceanic and Atmospheric Administration's Fisheries National Systematics Laboratory and colleagues reported finding a variety of chemical contaminants in nine species of cephalopods. "It was surprising...

TOKYO _ The Japan Aerospace Exploration Agency is considering building and launching a geostationary satellite to observe, around the clock, air pollution coming to Japan from China and other East Asian countries, The Yomiuri Shimbun learned Monday. The satellite's purpose is to find sources of air pollutants, including exhaust gas, carbon dioxide and carbon monoxide emitted from factories. It will utilize the information it gathers to issue early-stage photochemical smog warnings. The...

A research team of the University of Granada has managed to produce the most useful material to date to eliminate pollutants such as benzene, toluene and xylene, organic solvents widely used in the hydrocarbon industry and generated by road traffic in cities. The world-wide problem of the exposure to aromatic hydrocarbons has mainly focused its attention on benzene, which is considered to be harmful to health, even in low concentrations.This material is a monolithic carbon aerogel with the...

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...
