Environmental pollution consists of different types of pollutants in air, soil, and water. Due to the fact that plants can respond to environmental pollution, they can be used as bio-indicators for environmental monitoring. Air pollution in areas with oil and gas refineries nearby is an important problem. This study aims to survey the effects of gas refinery air pollutants on Conocarpus erectus...

background: this study aimed to compare the cytochrome p450 1a1 (cyp1a1) gene expression in the cord blood of infants born from mothers living in low- and high-air polluted areas. materials and methods: te study was conducted in spring 2012 in isfahan, the second large and air-polluted city in iran. the study comprised 60 neonates, consisting of 30 infants born from mothers residing in areas wi...

in this research, the effect of air pollution on proline concentration, soluble sugar, anatomical and morphological features was studied in two plant species malva parviflora and hordeum glaucum in 2009. the area of the stand steel factory of khuzestan was considered as the polluted site and shush region was considered as the control site, and sampling was carried out from the two sites, accide...

Recent air pollution incidents in Chinese cities prompted this study, which makes use of air particulate monitoring information being submitted by volunteer-owned equipment to a public website. As an indicator of severe air pollution spikes, such as those seen in February 2014, the daily average readings for all monitoring locations were mapped and animated as a time series. Figure 1: China air...

The correlation between air pollution and health effects in large Japanese cities presents a great challenge owing to the limited availability of data on the exposure to pollution, health effects and the uncertainty of mixed causes. A methodology for quantitative relationships (between the emission volume and air quality, and the air quality and health effects) is analysed with a statistical me...
