A cross-over study was conducted among 42 healthy adults during the summer of 2010 in Ottawa, Canada. Participants cycled for 1 hour along high and low traffic routes and ultrafine particles (UFPs) 0.1um in aerodynamic diameter, particulate matter (PM2.5) 2.5 µm in aerodynamic diameter, and black...

Radionuclides are elements that release energy called radiation. Radionuclides originate from both natural (e.g. soil and rock) and artificial (e.g. certain industrial, military and medical applications) sources...

A cross-over study was conducted among 42 healthy adults during summer 2010 in Ottawa, Canada. Participants cycled for 1-hour along high and low-traffic routes and volatile organic compound (VOC) exposures were determined along each route.

Survey of long-term measurements of radon concentrations in volunteer homes from 2009 – 2011. National survey conducted by the National Radon Program covering all Health Regions.

The determination of the trace element concentrations in food is important for consumer safety. Trace elements are metals that are present in low concentrations in air, water and soil. Thirty-four trace elements are commonly measured in TDS food sample composites. Although mercury and fluoride...

Polychlorinated biphenyls (PCBs) are a class of industrial chemicals that were used in a wide variety of applications including transformer oils, paints, and lubricants. PCBs are lipophilic compounds and accumulate in the tissues of biological organisms and bioconcentrate through the food chain....
