The findings of an HIA may be used to inform recommendations on whether to...

Using a Hierarchy of Evidence to Assess Chemical Health Risks of Artificial Turf

Over the past 40 years, artificial turf has become common in public and private settings. Compared to natural turf, artificial turf is easier to maintain, requires less water and no fertilizer, and provides a year-round access to playing surfaces. This is presumed to have important public health benefits by promoting physical activity and access to recreational space, although detailed research...

Cleanup Instructions for Small Mercury Spills - revised

Exposure to the small amount of mercury found in common household devices, such as fever thermometers, thermostats, or fluorescent light bulbs, is not likely to cause serious health problems. Humans are frequently exposed to greater quantities of mercury, much of it methylmercury, through diet. Nevertheless, all mercury spills, regardless of quantity, should be treated seriously and cleaned up ...
