Atmospheric mercury can be considered a ‘hot topic’. The problem of global mercury pollution is a focus of several international conventions such as the UNEP mercury program and the UN-ECE Long-Range Transport of Atmospheric Pollution Convention Task Force on Hemispheric Transport of Air pollution (HTAP). Major scientific questions are the oxidization processes of elemental mercury, global and ...

VOLUME 114 | NUMBER 5 | May 2006 • Environmental Health Perspectives Pick up any newspaper or magazine these days and there will most likely be a prominent story about the environment and its relation to human health, well-being, or economic security. It seems that environmental sensitivity is moving from the fringe to center stage. No better confirmation can be found for this than the adoption...

The organochlorine insecticide dichlorodiphenyltrichloroethane (DDT) was initially introduced for control of vector-borne discases It was banned in the United States by the Environmental Protection Agency in 1972 because of potential harmful effects on humans, wildlife and the environment. Since it is a potential human carcinogen, the United Nations Environmental Program (UNEP) has recently res...

Introduction Access to agricultural technology is seen as important for increasing food security and promoting development in many low-income countries (Clarke, 1997; Islam, 1995; Mitchell, Ingco, & Duncan, 1997; PinstrupAndersen, Pandya-Lorch, & Rosegrant, 1999). The green revolution provides some evidence to support a technology-led solution to the problem of feeding people (Trewavas, 1999). ...

The composition and distribution of saturated and aromatic hydrocarbons in near shore sediments, river sediments, and coastal peat of Alaskan Beaufort Sea: implications for detecting anthropogenic hydrocarbon i...

When assessing human health or ecosystem impacts of chemicals several calculation steps need to be addressed. Matrix algebra solving techniques are a useful approach to structure and solve the system of mass balance equations assessing chemical fate in environmental multimedia models. We suggest expanding this matrix approach towards a framework which includes the exposure, effect, and damage a...
