We analyzed two emission scenarios, one considering only the new incinerator, and the other accounting for the potential decrease in pollutant concentrations due to the activation of a district heating network.
The BMP relative sensitivity index revealed that most combinations of targeting methods and priority areas resulted in a proportional decrease in pollutant load from the subbasin level and watershed outlet.
At the end of this period, the laboratory tests' results showed a decrease in pollutant emissions, especially regarding nitrogen oxides and ultrafine particles.
By contrast to Beijing, Shanghai, and Tianjin, other cities in China did not experience a similar decrease in pollutant concentration.
The rapid decrease in pollutant tolerance in the absence of pollutant exposure is generally viewed as an indication that the tolerance has a cost (Sibly and Calow 1989; Van Straalen and Timmermans 2002; Medina et al. 2007; Saro et al. 2012).
Denmark has developed a national strategy for sustainable development for which the main goal is a constant decrease in pollutant levels in products, food, the working environment, traffic and the indoor environment [ 2- 5].
Model projections suggested decreases (~ 10 60%) in pollutant concentrations, mainly attributable to decreases in pollutants from local sources between 2001 and 2010.
To improve reliability of gradients, we used linear functions to represent the decreases in pollutant levels found in the initial portions of the exponential decay curves found in the literature.
For example, PentaBDE levels went down between 2006 and 2011, which may reflect decreasing use or may simply be due to the same factor causing decrease in legacy pollutant concentrations.
We did not evaluate changes in exposure for people who live or work near highways, nor did we assess health effects from decreases in other pollutants (e.g., carbon monoxide, sulfur dioxide) or the synergistic effects of combined changes in O3 and PM2.5.
