Three German motorways were selected (A4, A555, and A61), where runoff and deposits were analyzed to determine pollutant load moving into the roadside soil or into the drainage system.
Nevertheless, because most of the sediment-bound pollutants move with the finer sediments, this is not a modeling limitation.
This study suggests that the groundwater in the Umm Al-Aish basin has been significantly affected by hydrocarbon pollutants and it is predicted that these pollutants would move towards the Al-Raudhatain bore field if no preventive and/or remedial measures are taken in the near future.
The positive association between IL-6 and each pollutant declined with moving averages longer than 6 days.
For each pollutant, we calculated moving averages of 1, 2, 3, 5, 7, and 14 days preceding the day of CESD-R assessment as the metric for short-term exposure to ambient air pollution.
In our sensitivity analysis, we compared single- and two-pollutant models using moving average lag 2 days for pollutants.
Urban sediment can act as a transport mechanism for a variety of pollutants to move towards a receiving water body.
It has been predicted that these pollutants would move towards the Al-Raudhatain freshwater lens if no preventive and/or remedial measures were taken in the near future (KISR 2009).
With further adjustment for DNA methylation levels as potential mediators, associations between lung function and air pollutants (28-day moving average) stayed in the same direction; p-values were slightly larger and sometimes became nonsignificant for some genes such as OGG1 (data not shown).
Estimated associations between air pollution and perceived stress are given per interquartile range of the pollutant for the specific moving average.
