Marine pollutants in relation to planktonic and benthic organisms were examined at two locations along Karnataka coast, one at Kulai (74 degrees 47.74''E and 12 degrees 55.16''N) receiving huge amount of industrial effluents from fertilizer, petroleum and chemical plants along with the sewage discharges. The other site Padubidri (74 degrees 45''E and 13 degrees 10''N) is located 20 km away, whi...

This study was conducted to assess the effect of the water quality of El-Rahawy drain at El-Rahawy village, Egypt, on the African catfish Clarias gariepinus blood, biochemical parameters and histology of digestive tract, testis and ovaries. In addition to that, samples of water and C. gariepinus fish were collected from the River Nile at Delta Barrage in front of El-Kanater El-Khayria City as r...

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 ...

This study provides an empirical test of two mechanisms (social capital and exposure to air pollution) that are theorized to mediate the effect of neighborhood on health and contribute to racial disparities in health outcomes. To this end, we utilize the Social Capital Benchmark Study, a national survey of individuals nested within communities in the United States, to estimate how multiple dime...

Nature has slow occurring biogeochemical cycles of trace elements and heavy metals and the cycles have significantly controlled environmental fates of these elements. The trace elements and heavy metals cannot be degraded like organic pollutants and they may transform and become stable and persistent contaminants that accumulate in soil and sediments [1–3]. Estuaries play an important role in h...

The purpose of the work was performing Air Quality (AQ) forecast model. The idea has made a prediction of AQ in urban-industrial agglomeration basing on weather forecasts. Mezoscale meteorological forecasting UM model (Unified Model) developed by the UKMO, artificial neural networks and regression method was used. Two-step approaches were used to AQ forecasting. The first step was based on clas...

Introduction Degradation of the world's coral reefs is one of the most vivid examples of the effects of global environmental damage of marine ecosystems. The major stressors responsible for coral reef decline have been attributed to coastal urban and industrial development, agricultural activity, sedimentation, overharvesting, marine pollution, disease and climate change Reef species experienci...

Time location patterns are a significant factor for exposure assessment models of air pollutants. Factors associated with time location patterns in urban populations are typically due to high air pollution levels in urban areas. The objective of this study was to determine the seasonal differences in time location patterns in two urban cities. A Time Use Survey of Korean Statistics (KOSTAT) was...

Surface water is used for a variety of purposes like drinking, washing, bathing, recreation as well as numerous other varied industrial applications. The wholesomeness of these surface waters has become an issue of great concern. Water pollution is a burning issue all over the world. In recent years an increasing awareness has developed on the impact of human activities on the environment becau...

Coal based thermal power generation accounts for 44.7% of the world's electricity and coal alone provides about 80% of the total energy demand in India. Energy-intensive industries deteriorate the air quality of the residential areas due to release of different pollutants, especially a range of deleterious heavy metals like Hg, Cd, Cu, Pb, and Cr. Near about 53.3 percent of the coal produced ev...
