The case demonstrates how uncertainties in measurement and prediction of pollution runoff shape program design and participant perceptions.
However, there are several key methodological challenges in the estimation of the health effects of low-level exposure to air pollution, such as the shape of the exposure response curve, threshold of air pollution, interactive effects of air pollution and weather conditions, and model uncertainty and potential bias.
Contaminated area datasets with varying shapes should be tested to assess the efficiency of the geo-processing models we designed with other type of pollution coverage (and shapes).
Very few studies have completely assessed the shape of the relationship between air pollution exposure and reproductive outcomes.
Studies have found that perceptions on levels of air pollution are shaped by the presence of suspected sources of pollution such as industries or busy roads [ 8, 14].
The shapes of the SES air pollution curves for family income, wealth index, and individual education were evaluated using categorical analyses (Maclure and Greenland 1992) and were found to be generally linear (data not shown).
Consider physical characteristics of the area, such as size and shape, surrounding land use/land cover, runoff characteristics, point and nonpoint sources of pollution, water depth, and sediment transport characteristics.
The year is 2154, and Earth, thanks to the destructive effects of pollution, overpopulation and related ills, is in horrific shape.
Because of pollution, dams, overuse, and other impacts, freshwater habitats and species are in worse shape than any other ecosystem type.
The framework in Figure 1 suggests how area-level and individual-level stressors and buffers may combine to shape environmental hazard exposures, affect individual allostatic load, and in turn enhance susceptibility to the toxic effects of pollution exposures.
