  • Soil and sediment contamination assessment more accurate, says researcher

    Prolonged exposure of soil and sediment invertebrates to toxic Polycyclic Aromatic Compounds (PACs) has large and unpredictable effects on the life cycle of these species, concludes Dutch researcher Miriam León Paumen. These chronic effects can be very different from the effects of short-term exposure to PACs. Therefore, assessments of soil and sediment contamination are more reliable when they ...

  • `Green Clean:` Researchers determining natural ways to clean contaminated soil

    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 ...

  • Predicting amount of oil in contaminated soils

    Scientists are reporting a new technique for mapping and testing oil-contaminated soils. Traditionally, samples need to be collected from the field and returned to a lab for extensive chemical analysis, costing time and money when neither is readily available during a clean-up operation. The new method can take measurements in the field and accurately predict the total amount of petroleum ...

  • Soil contamination test improved with worms

    A Dutch researcher has discovered that exposing soil and sediment invertebrates like worms and springtails to toxic chemicals can give a more accurate test of soil contamination. Dr Miriam Leon Paumen also found that prolonged exposure can have a significant impact on the lifecycle of these invertebrates. The findings of this research give weight to the theory that gradual effects cannot be ...

  • Better detection of mercury contamination developed by researchers

    Mercury contamination has a negative impact on both the environment and human health. Researchers have developed a simple visual technique that will make detecting mercury pollution much easier. Mercury poses an international threat, as it can be transported through the air and through the food chain, especially via fish. It is mainly used in thermometers, barometers, dental fillings and ...

  • Evaluating risks from contaminated soil: a standardised approach

    Soil plays an important role, as a habitat capable of recycling water, carbon and nutrients and a provider of food and raw materials. Research investigating the risk assessment procedures adopted in different EU member states, suggests that there needs to be greater standardisation in the methods of assessing risks from contaminated soils. In 2005, the European Commission Joint Research Centre ...

  • Shedding a light on contaminants

    Name a current environmental challenge. Global climate change? Loss of endangered species? What about soil contamination? Soil pollution rarely makes headlines, though it is a prevalent global issue. According to the European Environment Agency, 39 member states in Europe had over 2.5 million contaminated soil sites in 2011. Sharon O’Rourke, researcher at University ...

  • Research shows efficiency of Huelva-grown shrub in recovery of polluted soil

    Researchers of the University of Seville and IRNASE (Institute of Natural Resources and Agrobiology), of the Spanish National Research Council (CSIC) have verified in controlled trials the efficiency of Erica andevalensis, or heather from Andévalo -- an endemic shrub from the province of Huelva and the Portuguese area of the Alentejo -- in the recovery of soils contaminated with heavy metals. ...

  • Household compost as good for soil as conventional fertilisers, say EU researchers

    Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

  • Land use affects potential health risks of cadmium and lead soil contaminants

    Exposure to polluted soil can affect human health, but the risk may vary depending on the soil type. A recent study has shown that the differing amounts of cadmium and lead that can be dissolved in the human digestive system can be predicted for contaminated agricultural, urban and woody habitat soils using a model. Its authors suggest this is a useful method for assessing the risks of ...

  • New research into PFAS treatment

    econ has taken on the challenge of finding a sustainable solution for the remediation of a group of contaminants. Yet still little understood but already of growing concern worldwide  – per- and polyfluoroalkyl substances, or short PFAS. Although research into the remediation of PFAS contaminated sites is still in its infancy, it is widely believed that thermal treatment is the only ...

  • Soil management in China and the EU

    Following rapid urbanisation, management of contaminated soil has become a political priority in China. In this study, researchers reviewed the current system in China as compared to Europe and provide recommendations for the sustainable management of soil. China’s rapid economic growth, and the accompanied urbanisation, has come at a considerable cost to the environment. In the late 1990s, ...

  • Protecting valuable urban soil

    Soil provides multiple services, ranging from food production, water-filtering and carbon capture, to green park areas in towns and cities, important for human well-being. However, increased urbanisation is leading to a loss of soil resources. Researchers have developed an online evaluation method that can be used as an aid to urban planning to avoid the loss of precious areas of good quality ...

  • Measuring global soil changes

    Global change is increasingly affecting important terrestrial ecosystem functions such as the filtering and buffering capacity of soils, the supply of clean water, soil fertility, and consequently, the production of food, feed, and fiber. Recent studies and reports from the United Nations indicate that water and soil resources are both heavily under pressure. Worldwide about 2 billion ha of land ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns. Now, Eawag has developed a model that allows vulnerable areas to be pinpointed using existing data on geology and soil ...

  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Does pasture irrigation increase groundwater contamination?

    Concern about microbial contamination of groundwater from foraging dairy cows has increased as spray irrigation practices in New Zealand have increased over the years. Bacteria capable of living in both animals and humans are commonly found in cow manure.
