This guideline technical document evaluated the available information on fecal indicator organisms in recreational waters with the intent of updating/recommending guideline values. The purpose of this consultation is to solicit comments on the proposed guidelines, on the approach used for their...

There are a number of mitigating measures for vapour releases at gasoline stations based on the Environmental Code of Practice issued by the Canadian Council of Ministers of the Environment (CCME 1991). These measures, which include Stage 1 vapour recovery (Figure 6), were designed to reduce the...

Uncertainties in evaluating the risk to human health: Recent Canadian benzene concentrations based on monitoring data at or near gasoline station operations were not available. Estimates of benzene concentrations emitted from gasoline stations were based on modelled values of total evaporative...

Conclusion: In this report, the short-term benzene releases occurring due to tanker truck unloading of gasoline into storage tanks at gasoline stations and long-term releases of benzene from gasoline station total evaporative losses are estimated. For those living in the vicinity of the gasoline...

Air pollution is a major contributor to the development of disease and premature death. It also represents the largest environmental risk factor to human health (WHO 2016). Exposure to air pollution increases the risk of dying prematurely from heart disease, stroke and lung cancer.

Air pollution is recognized globally as a major contributor to the development of disease and premature death and represents the largest environmental risk factor to human health (WHO 2016). Exposure to air pollution increases the risk of premature mortality from heart disease, stroke and lung...

The purpose of this guidance is to summarize ways to remediate, maintain and improve indoor air quality in office buildings. This guidance provides practical recommendations to address and respond to potential IAQ problems, including guidance for reducing pollutant sources and properly operating...

Indoor air quality refers to the quality of the air in an indoor environment, such as inside a building, particularly as it relates to the health and comfort of occupants. Indoor air quality is the result of the constantly changing complex interactions among building systems, the environment...

Building operators and those responsible for IAQ should be knowledgeable about the ventilation system design and operation, which includes the outdoor air supply, outdoor air quality, filters and filtration efficiency, space planning, equipment maintenance, controlling other contaminant pathways...

Poor indoor air quality can affect your health. The most effective way to improve your indoor air is to identify activities that can contribute to poor indoor air quality and remove or reduce the sources of indoor air pollutants.

Stewardship refers to overseeing and being responsible for the care and maintenance of property. Building operators and the employer are often able to directly and positively impact IAQ through building stewardship. By understanding IAQ and the interaction between products, furnishings,...

Everyone has a role to play in maintaining good IAQ in the workplace, from the employer and building operators, to the health and safety committee and the employees.

The IAQ resolution process will often involve responding to a reported air quality issue. Occupants may report concerns through the supervisor or manager, the health and safety committee or representative, the union, or the employer. As a best practice, it is recommended that the employer have a...

Building operators or employers may need to hire the services of a qualified professional or organization that has the necessary skills, training and equipment to further investigate and remediate the issue.

Indoor air quality professionals may include industrial or occupational hygienists, public health or medical professionals, environmental consultants, or other professionals that have an understanding of IAQ along with the training and equipment to investigate more detailed air quality issues,...

Indoor air quality (IAQ) is a recognized health and safety issue. Indoor air quality issues may occur in buildings when chemical and biological contaminants exist at levels that may pose a health risk to building occupants. It is also important to note that some building occupants may be...

Health-based air quality objectives will identify safe exposure levels of outdoor air pollutants of concern for human health.

Fine Particulate Matter (also known as PM2.5) are particles in the air that measure less than 2.5 micrometers (μm) in diameter, and typically consists of a mix of things like smoke, soot, liquid or solid particles in aerosol, or biological matter like mould, bacteria, pollen and animal dander....
