摘要: ABSTRACT The role of ambient levels carbon monoxide (CO) in the exacerbation heart problems individuals with both cardiac and other diseases was examined by comparing daily variations CO fluctuations nonaccidental mortality metropolitan Toronto for 15-year period 1980–1994. After adjusting time series day-of-the-week effects, nonparametic smoothed functions day study weather variables, statistically significant positive associations were observed between monoxide, nitrogen dioxide, sulfur coefficient haze, total suspended particulate matter, sulfates, estimated PM2.5 PM10. However, effects this complex mixture air pollutants could be almost completely explained particulates (TSP). Of 40 deaths Toronto, 4.7% (95% confidence interval 3.4%–6.1%) attributable to C...
