METRO Vancouver said on Tuesday that while there was an odour present and sulphur dioxide levels did increase on Sunday because of an incident at Parkland Refining in Burnaby, Metro Vancouver’s air quality objectives for those air contaminants were not exceeded at the monitoring stations during the event.

It said that these air contaminants are continuously measured at its monitoring stations and data are available at airmap.ca, along with current air quality information. Metro Vancouver received very few odour complaints related to the refinery on Monday.

The Sunday incident resulted in a strong chemical odour being reported in some areas of the region. Consequently, Metro Vancouver received more than 100 odour complaints from people in Vancouver and Burnaby.

Metro Vancouver said it will continue to monitor air quality and work with the health authorities.
