A 150-foot-high garbage dump in Colombia, South America, may have new life as a public park. Researchers at the University of Illinois have demonstrated that bacteria found in the dump can be used to neutralize the contaminants in the soil. Jerry Sims, a U of I associate professor of crop sciences and USDA-Agricultural Research Service research leader and Andres Gomez, a graduate student from Medellín, Colombia, have been working on a landfill called “El Morro” in...

A green technique for capping and cleansing old urban landfill sites and mine dumps has been successfully trialled in South Australia. Known as ℠phytocapping´, it uses green plants to reduce rainwater flow into old dumps that could release pollution into nearby groundwater and streams or greenhouse gases into the atmosphere. The plants can later be harvested to produce clean energy. The CRC for Contamination Assessment and Remediation of the Environment and technology firm...

Japanese royal fern tops list for formaldehyde removal effectiveness Formaldehyde is a major contaminant of indoor air, originating from particle board, carpet, window coverings, paper products, tobacco smoke, and other sources. Indoor volatile organic compounds (VOCs) such as formaldehyde can contribute to allergies, asthma, headaches, and a condition known as ''sick building syndrome". The concern is widespread; a 2002 report from the World Health Organization estimated that undesirable...

Study Examines the plant-soil relationship and the uptake of Contaminants in Ryegrass The environmental concern is great when considering the role of toxic contaminants in the plant-soil relationship. Understanding plant's absorption and accumulation of these contaminants from the soil would be incredibly beneficial. One highly carcinogenic contaminant commonly found in soil is called polycyclic aromatic hydrocarbons. They are the byproduct of the incomplete combustion of coal, oil, gas, and...

A team of Australian and Chinese scientists has pioneered a new way to make clean energy from land so contaminated with toxic waste that it is good for little else. A collaboration between researchers from Australia's CRC for Contamination Assessment and Remediation of the Environment (CRC CARE) and its offshore partners HLM Asia Group and Shaoguan University has delivered proof of concept for a new system for cleaning up badly polluted land that produces greenhouse-friendly energy for homes...

When conditions become complicated, there is no choice but to adapt to them. Plants have to do the same. Some of them growing in mining areas have unusual strengths, accustomed as they are to living in a toxic environment and knowing how to deal with this. Based on this capacity to adapt, researcher Ms Lur Epelde used these plants as medicinal herbs for contaminated soils. The current level of contamination in the soil, caused by human intervention - is highly worrying. Nevertheless, more...

5 super ornamentals identified for cleaner indoor air Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time indoors. Surprisingly, indoor air has been reported to be as much as 12 times more polluted than outdoor air in some areas. Indoor air pollutants emanate from paints, varnishes, adhesives, furnishings, clothing, solvents, building materials, and even tap water. A...

Researchers at North Carolina State University are working to demonstrate that trees can be used to degrade or capture fuels that leak into soil and ground water. Through a process called phytoremediation "“ literally a "green" technology "“ plants and trees remove pollutants from the environment or render them harmless. Through a partnership with state and federal government agencies, the military and industry, Dr. Elizabeth Nichols, environmental technology professor in NC...
