| dc.description.abstract | A seven months analysis of pollution levels for particulate matter (PM2.5) in air, toxic metals in snow, as well as noise was undertaken and mapped in the Mission Industrial Area (MIA) and South St. Boniface (SSB) neighbourhood in Winnipeg, Manitoba. Daytime respirable fine particulate matter (PM2.5) was monitored by Dylos DC 1700 PM air quality monitor and A-weighted noise level measurements was taken by Reed Digital Sound Level Meter. Evaluation of toxic metals (lead, chromium, arsenic, nickel, mercury and zinc) in snow were measured and compared to different pollution indices, including: contamination factor (cf), degree of contamination (cd) and pollution load index (PLI) for heavy metals. The PM2.5 Canadian Ambient Air Quality Standard of 28 μg/m3 was sporadically exceeded downwind of the property line of the scrap metal shredder, with 5 out of 35 days averaging between 28.9 μg/m3 to 38.1 μg/m3. During the wildfire in August, the levels were high in the residential area at 21.9 and 25.6 μg/m3 although other monitoring days ambient levels averaged 0.59 μg/m3 to 9.81 μg/m3, indicating satisfactory PM2.5 levels. However, the cf indices were high for lead, zinc, nickel and mercury compared to background levels in MIA and SSB. One-way ANOVA and Spearman rank correlation analysis revealed statistically significant higher levels for PM2.5 and heavy metals concentration in snow MIA and SSB. Mapping showed the highest pollution of PM2.5, contaminant factors (cf), noise were downwind of IM and radiating out, but reducing and remaining significantly above background levels. Also, the noise levels regularly exceeded the city by-law level in the MIA, on the properties adjacent to the scrap metal shredder, with 90% of the sampling time over 200 hours (number of days= 35). The 55 dBA by-law guideline was also exceeded in the residential areas on 4 days out of the 33 monitored. This research shows high particulate matter, toxic heavy metals and noise levels adjacent to the scrap metal shredding operation in IM, which suggests the need for regulatory action to enclose the shredder for pollution control. | en_US |
