A study was carried out to investigate the effects of meteorological conditions on atmospheric pollutant concentrations in a complex area. In general serious pollution episodes in the urban and suburban environment are not directly caused by sudden increases in the emission of pollutants but results from unfavorable meteorological conditions, These unfavorable conditions may reduce the ability ...

Photocatalytic degradation of chemical pollutants in water was investigated using semiconductor oxide catalysts, zinc oxide (ZnO) and titanium dioxide (TiO2) and phenol as the substrate. Influence of various parameters such as characteristics of the catalyst, irradiation time, substrate and catalyst concentrations, pH etc. has been studied and optimum conditions for the complete degradation of ...

Lung tissue slices are model systems for the study of pulmonary metabolism. Because of the speed and simplicity of slice preparation, lung slices have been used in studies of oxygen, amino acid, carbohydrate and lipid utilization and adenine nucleotide metabolism. Dose-response characteristics for toxicants are readily described because multiple lung samples can be studied from the same animal ...

poly aromatic hydrocarbons are hydrophobic organic compound found as major contaminants in soil. soil biological activities are vital for the restoration of soil contaminated with hydrocarbons. successful application of bioremediation technology to contaminated soil requires knowledge of the characteristics of the site and the parameters that affect the microbial biodegradation of pollutants. t...

There has always been a paramount concern over the widespread occurrences of various pollutant types, around the globe. With ever increasing scientific knowledge, socio-economic awareness, human health problems and ecological apprehensions, people are more concerned about the widespread environmental pollutants. Thus, the occurrences of newly identified pollutants so-called ―emerging pollutants...

Obesity and associated metabolic disorders represent a major societal challenge in health and quality of life with large psychological consequences in addition to physical disabilities. They are also one of the leading causes of morbidity and mortality. Although, different etiologic factors including excessive food intake and reduced physical activity have been well identified, they cannot expl...

Although particulate matter (PM), nitrogen dioxide (NO2) and carbon monoxide (CO) typically exist as part of a complex air pollution mixture, the evidence linking these pollutants to health effects is evaluated separately in the scientific and policy reviews of the National Ambient Air Quality Standards (NAAQS). The objective of this analysis was to use meta-regression methods to model effect e...
