Due to the complexity of pollutants and the difficulty of destruction, conventional treatments could hardly remove organic compounds.

This led to high correlations between the spatiotemporal estimates of these pollutants and thus difficulty in the interpretation of results from these pollutants independently.

Unstable results for the gaseous pollutants highlight the difficulty in determining appropriate methods for controlling for meteorology in air pollution epidemiologic models, particularly when analyzing covarying pollutants that are highly driven by meteorologic processes.

Calculating risk assessment of air pollutants poses particular difficulties.
