In recent years, the haze occurs frequently and air pollution is getting worse in Beijing-TianjinHebei Region, China. The particulate matter pollution characteristic researches are playing a significant role especially in the districts where have higher concentration PM and air pollution. In this study, we collected daily particulate matter (PM10, PM2.5) mass concentration data from 7 air pollu...
This study addresses the synergies of mitigation measures to control urban air pollutant and greenhouse gas (GHG) emissions, in developing integrated "co-control" strategies for Mexico City. First, existing studies of emissions reduction measures--PROAIRE (the air quality plan for Mexico City) and separate GHG studies--are used to construct a harmonized database of options. Second, linear progr...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
Conventional approaches to stormwater quality evaluation combine continuous flow rate monitoring and automated sample collection for chemical analysis to derive an event mean concentration for each pollutant of concern. This approach requires expensive flow monitoring and automated sample collection equipment and the costly analysis of high numbers of water samples. Consequently, such monitorin...
Short-term exposures to outdoor air pollutants have been associated with lower lung function, but the results are inconsistence. The effects of different pollutant levels on lung function changes are still unclear. We quantified the effects of outdoor air pollution exposure (NO2, PM10, O3, and PM2.5) on lung function among 1,694 female non-smokers from the Wuhan-Zhuhai Cohort in China by using ...
the outcomes of development of urbanization as pollution of air, water and urban environment are great threats to the health and safety of urban residents. nowadays, urban areas as centers of population and economic activities show high concentrations of pollutants; so that, inconvenient locations of irksome and pollutant jobs in metropolitans such as isfahan city have led to serious threats to...
