North Portland Air Quality Monitoring Project

Portland N Stafford St air toxics monitors​During the 2014 legislative session, DEQ was funded to conduct air toxics monitoring in the Swan Island area of North Portland.

DEQ began monitoring near Swan Island in November 2014 and will continue for one year. A full spectrum air toxics monitor located above Swan Island measures volatile organic compounds, particulate matter (including diesel), polyaromatic hydrocarbons, and metals. A metals only monitor is sited in the St. John’s neighborhood and eight meteorology stations provide information about temperature, wind direction and speed to track weather conditions associated with elevated air pollution.
By collecting and analyzing additional monitoring and meteorology data, DEQ hopes to gain a better understanding of air toxics sources and exposures and risks associated with those exposures. The data can help determine what emission reduction options might be necessary to mitigate risks from exposure to toxic pollutants in the area.
By comparing complaint and industrial facility data to wind speeds and directions, DEQ will be better able to identify air pollution sources and patterns from facilities. This will allow more informed odor investigations and responses under DEQ’s Nuisance Odor Strategy.
