Abstract

Abstract

MiniVol Tactical Air Samplers were placed in three locations to collect samples from January 30 – February 29, 2020. Two sampling locations resided on the Kamloops Indian Band reserve, one residential area in Sun Rivers and one industrial location on Athabasca Way; one remained at the TRU Weather Station to collect background. The PM2.5 matter collected on membrane filter papers over an average period of 24 hours. Concentrations of metals—lead, arsenic, cadmium, chromium, copper, zinc and iron—were determined spectroscopically. Filter papers were prepared for metal analysis by microwave digestion (Anton Paar Multiwave GO) with Aqua Regia and relative amounts were determined using a Varian Flame Atomic Absorption Spectrometer (F-AAS). Small, but detectable levels of metals were found. The relative amounts of metal varied by location, with higher concentrations corresponding to the sampler in the industrial location. This project was carried out with the permission of the Tk’emlúps te Secwepemc Band council, who provided the air-samplers.
