Nanotechnology: A Review of Exposure, Health Risks and Recent Regulatory Developments

Nanotechnology is the creation of materials, devices, and systems by controlling matter at the nanometer scale (1-100 billionths of a meter). Potential exposures to engineered nanoparticles (ENPs) through contact with consumer products or air, water, and food sources are an emerging potential threat to human health. ENPs have unique properties and characteristics in addition to size, such as a...

Impact of Home Preparation and Cooking Methods on Levels of Dioxin and Dioxin-Like Compounds in Foods

Human exposure to dioxins and dioxin-like compounds (DLCs) is primarily from ingestion of fish, meat, and dairy products. Based on studies where populations were exposed to much higher levels of DLCs than the general population would encounter, some DLCs have been classified as carcinogens/ probable carcinogens.  However, uncertainty remains about the possible adverse health effects from low-...

Does Eating Organic Food Reduce Pesticide Exposures and Health Risks?

Diet is an important source of pesticide exposure, particularly for children, but data are lacking on the amount of pesticides consumed in the diet relative to exposures from other sources. Available data suggest that organically-grown food contains fewer synthetic pesticide residues than conventionally-grown food, and that eating an organic diet can result in lower exposures to some pesticides...

Pepper Spray in the Indoor Environment and in the Vicinity of Food Products and Preparation Surfaces

Pepper spray is discharged during an attempted robbery of a jewellery store in a large urban mall.  The robbery site is located next to the mall’s food court.  For several days, mall patrons continue to report uncomfortable symptoms (e.g., burning sensation in their eyes and throat) when they enter the food court.  Public Health Inspectors (PHIs) are asked to respond to concerns about...
