Which regulation sets limits for VOC concentration in Canada?

The regulation that sets limits for VOC concentration in Canada is indeed the Canadian VOC Concentration Limits. This regulation is specifically designed to address indoor air quality by specifying the acceptable levels of volatile organic compounds (VOCs) in various products such as paints, adhesives, and finishes. By implementing these concentration limits, the regulation aims to reduce health risks and environmental impacts associated with the use of VOCs in buildings and products used in indoor environments.

The other options relate to different contexts or regions. The Hong Kong Air Pollution Regulation pertains to air quality in Hong Kong, while ISO 16000 is a standard focused on indoor air quality measurement but does not set specific VOC limits in Canada. AgBB is a German evaluation scheme for VOC emissions from building products but does not apply to Canada. Thus, the Canadian VOC Concentration Limits are the most relevant and applicable to regulating VOC levels within Canadian jurisdictions.
