Hi Everyone, SOCAAR is pleased to announced our first In-Person (also available online) Seminar in 2.5 years!! Please see the below information for our First Speaker in our 2022-2023 Series. Prof. Meredith Franklin Associate Professor Department of Statistical Sciences School of the Environment University of Toronto Title: Non-tailpipe particles: sampling, exposure models, and health effects Abstract: Traffic-derived air pollution comprises of a mixture of gaseous pollutants and particulate matter (PM) from exhaust (tailpipe) as well as non-exhaust (non-tailpipe) emissions. Non-tailpipe emissions mainly arise from mechanical abrasion of brakes and tires, erosion of road surfaces and resuspension of a mixture of dust that accumulates on road surfaces. Most epidemiological and experimental research into traffic-related pollution focuses on tailpipe exposures, with far less attention paid to non-tailpipe exposures despite the fact that it is an important source of toxic metals in urban atmospheres. We present results of the Intra-Community Variability study, a spatially intensive sampling campaign of PM concentrations at multiple size fractions (quasi-ultrafine, accumulation mode and coarse) collected and analyzed for chemical speciation at over 220 locations across Southern California. With a focus on non-tailpipe metal tracers, we further developed spatiotemporal land use regression models to generate exposures with which we conducted a health effects study of the association of children's lung function. ________________________________________________________________________________ Microsoft Teams meeting Join on your computer, mobile app or room device Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3ameeting_OWJjYTA0OTEtMTc5ZS00NGY4LTgwODgtYWI0YTM5NjM2YWIx%40thread.v2/0?context=%7b%22Tid%22%3a%2278aac226-2f03-4b4d-9037-b46d56c55210%22%2c%22Oid%22%3a%2276a2f469-c5cc-446a-8132-c4bf6f5856ed%22%7d> Meeting ID: 237 702 617 152 Passcode: G84QEb Download Teams<https://www.microsoft.com/en-us/microsoft-teams/download-app> | Join on the web<https://www.microsoft.com/microsoft-teams/join-a-meeting> Or call in (audio only) +1 647-794-1609,,409051224#<tel:+16477941609,,409051224#> Canada, Toronto Phone Conference ID: 409 051 224# Find a local number<https://dialin.teams.microsoft.com/d82c5eb5-d575-428c-bac3-869ecf09d547?id=409051224> | Reset PIN<https://dialin.teams.microsoft.com/usp/pstnconferencing> Learn More<https://aka.ms/JoinTeamsMeeting> | Meeting options<https://teams.microsoft.com/meetingOptions/?organizerId=76a2f469-c5cc-446a-8132-c4bf6f5856ed&tenantId=78aac226-2f03-4b4d-9037-b46d56c55210&[log in to unmask]&messageId=0&language=en-US> ________________________________________________________________________________
