Chemical Stabilization Procedures Successfully Recover Brownfield Sites
Posted on October 31, 2007 - Filed Under Air Pollution, Curbing Pollution, Environmental Pollution, General, Global Warming, Land Pollution, Ocean Pollution, Pollution News, Water Pollution
A new way to clean up brownfield sites, which are abandoned industrial or commercial lands contaminated by low concentrations of hazardous waste or pollutants, has been developed. Common contaminants of industrial sites include copper, chromium, and arsenic. Iron-containing blaster sand treatment appeared to produce better long-term effects than treatment with oxygen-scarfing granulate.

The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.

A team of staff and students from University College London are competing in one of the world’s toughest engineering tests — the Panasonic World Solar Challenge. The biennial event sees teams build their own solar-powered cars and then race them over a gruelling 3000km course from Darwin to Adelaide.

Air pollution is becoming one of the biggest dangers for the future of the planet, causing premature deaths of humans and damaging flora and fauna. With their vantage point from space, satellites are the only way to carry out effective global measurements of air-polluting emissions and their transboundary movement.

Almost 90 Canadian communities have experienced a shift in the normal 51:49 ratio of male to female births, so that more girls than boys are being born, according to two new studies. The researcher identified inverted male sex ratios, sometimes as profound as 46:54 in almost all of the communities studied.

Nitrogen oxides, the noxious byproduct of burning fossil fuels that can return to Earth in rain and snow as harmful nitrate, could taint urban water supplies and roadside waterways more than scientists and regulators realize, according to new research in the journal Environmental Science and Technology.

Creating “national parks of the sea” may be the only effective way to reverse trends that have left 76 percent of world fish stocks fully- or over-exploited and marine biodiversity at severe risk, according to the new report, Oceans in Peril: Protecting Marine Biodiversity. The four environmental experts call for a radical change in fisheries management, from a single-species approach to one that is ecosystem based and also includes the use of precautionary measures to tackle pollution and to reduce carbon dioxide emissions that are changing the temperature and chemistry of the oceans.

The University of Maryland Solar Decathlon Team capped its “silver” honors in the U.S. Department of Energy competition by winning the BP Solar People’s Choice Award on Saturday. Competing innovative homes run entirely with solar power. The Maryland LEAFHouse has one of the few technical innovations in the competition — a waterfall that incorporates design and function to reduce moisture and the energy needed for air conditioning, called a liquid desiccant system.

Posted on October 21, 2007 - Filed Under Air Pollution, Curbing Pollution, Environmental Pollution, General, Global Warming, Land Pollution, Ocean Pollution, Pollution News, Water Pollution
The latest Taking Stock report from the Commission for Environmental Cooperation reveals a continued decline in releases of toxic chemicals to the environment — 15 percent for the US and Canada from 1998 to 2004 — driven by a group of industrial facilities that are the largest generators of emissions. The report also, however, reveals a substantial increase in chemical releases and transfers by a much larger group of industrial facilities that report lower emission volumes.

Posted on October 18, 2007 - Filed Under Air Pollution, Curbing Pollution, Environmental Pollution, General, Global Warming, Land Pollution, Ocean Pollution, Pollution News, Water Pollution
The US Environmental Protection Agency must take a more aggressive leadership role in implementing the Clean Water Act if water quality in the Mississippi River and the northern Gulf of Mexico is to improve, says a new report from the National Research Council. EPA has failed to use its authority under the act to adequately coordinate and oversee state activities along the Mississippi and ensure progress toward the act’s goal of ‘fishable and swimmable’ waters, the report says.
