Augmented Air Sampling - Dundalk, Ontario Summer 2016
During the summer of 2016, ambient air sampling for formaldehyde was conducted in the town of Dundalk as a joint project of the Grey Bruce Health Unit (GBHU) and the local Ministry of Environment and Climate Change (MOECC) office, with technical support from Public Health Ontario (PHO).
2015 Grey Bruce Air Quality Study
A study confirms air quality at the Tiverton air monitoring station reflects the larger picture of air quality across Grey Bruce. In a four-month period in the summer of 2015, a mobile air quality monitoring unit, call an Airpointer, was set up in three locations in Grey Bruce (Owen Sound, Hanover and Northern Bruce Peninsula). Measurements were taken of ambient concentrations of three common pollutants; ozone, nitrogen dioxide and fine particulate matter. The data collected at the three sites matched the data collected at the same time at the Tiverton station. The findings confirm the Tiverton Air Quality Health Index can be considered representative of measurements of common pollutants across Grey Bruce.
Grey Bruce State of the Environment Report
An Ecohealth perspective was applied to a State of the Environment report for Grey Bruce Health Unit and summarized environmental and health data relevant for public health practice. We aimed for comprehensiveness in our data compilation, including: standard media categories (e.g., air, water, land); and ecological indicators (e.g., vectors, forests, wetlands)
What is Tritium?
Tritium is a radioactive form, or “isotope", of hydrogen. Like all radioactive isotopes, tritium decays. As it decays it gives off beta radiation.
One of the more common uses of tritium involves glow-in-the-dark lighting and signs. Tritium gas is combined with phosphor to create luminescence. The light source does not require electricity or electrical wiring, making it ideal for exit signs, emergency lighting in commercial buildings and airplanes and for airport runway lights. Tritium is also used as a tracer in biomedical and academic research.

Regulation of Tritium
The Canadian Nuclear Safety Commission (CNSC) regulates releases of tritium by nuclear reactors and tritium processing facilities to ensure the health and safety of workers and the public, and the protection of the environment. The link below brings you to the specific results of the CNSC monitoring program for the various nuclear facilities in Canada. This includes information on the levels of radiation detected, along with a comparison to health guidelines or reference levels
