  • Pesticide impact: comparing lab, field-scale results

    Assessing the environmental risk of pesticide use is an important, complex task that requires knowledge of the equilibrium sorption parameter. This helps researchers assess the risk of pesticides leaching into groundwater. For cost-effective assessments, this is usually determined through batch experiments that find the amount of pesticide in test soils as a function of concentration at a ...

  • Finding alternatives to mercury in small-scale gold mining

    Artisanal small-scale gold mining (ASM), largely practised in Asia, South America and Africa, contributes significantly to mercury emissions, both in the developing world and globally. A recent study investigates an alternative to using mercury in ASM. The EU Mercury Strategy1 recognises the need for global action to reduce mercury in the environment. This includes actions to help other countries ...

  • Ground-penetrating radar used to prepare for archaeological dig at Amherst Historical Museum

    A high-altitude Peruvian rock shelter, Mayan ruins and caves in France are among the sites around the world where a three-wheeled device resembling an oversized tricycle has revealed what lurks below the ground’s surface. While the lawn of the Amherst Historical Museum on Amity Street may not be the most unusual place that Peter Leach has brought his ground-penetrating radar, ...

  • Is biochar the answer for ag?

    Scientists demonstrate that biochar, a type charcoal applied to soils in order to capture and store carbon, can reduce emissions of nitrous oxide, a potent greenhouse gas, and inorganic nitrogen runoff from agriculture settings. The finding will help develop strategies and technologies to reduce soil nitrous oxide emissions and reduce agriculture’s influence on climate change. A research ...

  • Ruining the world’s water supply

    Agricultural run-offs containing fertilizers, animal wastes and pesticides are infecting rivers and water courses with blue-green algal blooms and toxic chemicals. While the problem is particularly evident in developing countries - Canada, Australia and the United States contain some of the world’s most polluted rivers, and poor agricultural practices are the root cause. Almost one-fifth ...

  • Cleaning up the effects of stormwater with biofilters

    Stormwater in urban areas can have negative effects on both the quantity and quality of surface- and ground-waters. Biofiltration systems are a popular form of water treatment, but information on their performance with stormwater is limited to laboratory studies. This research is the first to evaluate three biofiltration systems in practice. Biofiltration systems (otherwise known as biofilters, ...
