OBJECTIVES The epidemiological evidence for adverse health effects of long-term exposure to air and noise pollution from traffic is not coherent. Further, the relative roles of background versus near traffic pollution concentrations in this process are unclear. We investigated relationships between modelled concentrations of air and noise pollution from traffic and incident cardiorespiratory di...
BACKGROUND Air pollution has been associated with respiratory health effects. There is little direct evidence that reductions in air pollution related to abatement policies lead to actual improvement in respiratory health. We assessed whether a reduction in (traffic policy-related) air pollution concentrations was associated with changes in respiratory health. METHODS Air pollution concentrat...
The Action Plan for Water Pollution Prevention and Control (i.e., the "10-Point Plan") is a regulation formulated by China to prevent control water pollution ensure China's safety. To test policy effect of Plan", we use data from 269 cities period 2012 2017 examine whether implementation plan can help reduce intensity industrial pollution. results show that in Central Western significantly high...
It is widely known that the railroad diesel locomotive engines emit significant amount of air pollutants. However, these engines are not equipped with any air pollutants reducing devices in Korea, resulting in the accumulative air pollution near the railroad. Because the pollutants emission from driving locomotive engines cannot be measured directly, the emission factors based on the amount of ...
The aim of the study was to analyse relationship between PM2.5 and PM10 concentrations, traffic density meteorological factors during week with regular regime first COVID-19 lockdown in Novi Sad, Serbia. During period, which included working days weekends, emission contributions PMs were also determined. Obtained results have shown higher PM, pressure contribution values, lower temperature, rel...
