Today we review research into the links between mortality of the adult Dutch population and exposure to NO2 and PM10 that establishes a new basis for that country. Results indicate a higher general mortality association with PM10 than previously estimated and with NO2 for all mortality except circulatory disease.
Key Quotes:
“In this large Dutch nationwide population cohort of > 7 million adults we observed positive significant associations between estimated long-term exposure to air pollution (PM10 and NO2) at the home address and nonaccidental, circulatory disease, respiratory disease, and lung cancer mortality”
“the median PM10 concentration was 29 μg/m3 [5th–95th percentile, 24 μg/m3–32 μg/m3; interquartile range (IQR) = 2.4]; the median NO2 concentration was 31 μg/m3 (5th–95th percentile, 19 μg/m3–44 μg/m3; IQR = 10.0 μg/m3). We estimated HRs per 10-μg/m3 increase in the pollutant concentration..the range (and IQR) in NO2 concentrations is larger than the range in PM10 concentrations, because NO2 is more influenced by local (traffic) emissions than PM10, which is more affected by long-range transport.”
“we found particulate matter to be associated with all outcome measures that we have analyzed. Our relative risk estimate for PM10 on total mortality is higher than the relative risk estimate from a recent published study based on 19 European cohorts”
“For NO2 we found statistically significant associations with all outcomes except for circulatory disease mortality”
“Our estimates for lung cancer mortality for PM10 and NO2 are higher than those published recently in the national cohorts”
