Farmworkers can be exposed to a wide variety of cholinesterase inhibiting pesticides. Routine screening for cholinesterase inhibition is not required in many states in the United States, or may be required for workers that apply or handle pesticides, but not those doing routine work in the fields.

Water supplies in many regions of the world are contaminated with arsenic, which is known to cause several diseases including cancer and skin lesions. Less is known about effects of arsenic on the nervous system, especially following developmental exposure. Wang et al.

There has been increased interest in the possible impact of climate change on human health, particularly as it relates to the transmission of environmentally sensitive diseases such as malaria. Parham and Michael investigated the role that process-based mathematical models can play in providing strategic insights on the effects of climate change on malaria transmission.

One challenge in assessing the health effects of human exposure to air pollution in epidemiologic studies is the lack of widespread historical air pollutant monitoring data to characterize past exposure levels. Davis et al. (p.

Urban air pollution is reportedly responsible for nearly 1 million annual deaths worldwide. The burden of disease from air pollutant exposure may be greatest in growing urban populations in the developing world, but risk assessment is often impeded by lack of exposure information at the local level in many urban settings. Dionisio et al. (p.

Early-life exposure to environmental pollutants such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) or diets high in fat has been associated with an increased risk of cancer. La Merrill et al. (p. 596) investigated how developmental exposure to TCDD and a high-fat diet (HFD) might interact to alter breast cancer susceptibility in a laboratory animal model.

The state of Maine experimented with drugs last year. The state had already tested several methods?for collecting unused pharmaceuticals, with varying degrees of success.

Imagine the most sophisticated engineering feat you can think of, and you might not consider a living cell. And yet cells are fabulously sophisticated, able to produce all the proteins, tissues, and biological circuits that give rise to life. Scientists have spent hundreds of years just trying to understand cells and to work with them as they were created by nature.

Inhaled asbestos fibers may contribute to three-fourths of malignant mesotheliomas diagnosed in men and almost 40% of cases diagnosed in women.
