It has been reported that cigarette smoking is a risk factor for bacterial pneumonia and other respiratory infections, and that smokers are more likely to harbor bacterial pathogens in their oral and nasopharyngeal cavities than nonsmokers. Effects of tobacco smoke and its constituents on immune function and mucociliary clearance have …Magnetic susceptibility distribution in the soils of Pune Metropolitan Region: implications to soil magnetometry of anthropogeni
Based on established linkages between ferrimagnetism and heavy metal concentration of anthropogenic particulates, we attempt here to delineate pollutant residing domains and study the role of surface runoff and wind circulations over its redistribution in the Pune Metropolitan Region (PMR) in Maharashtra.Distribution of arsenic and mercury in subtropical coastal beachrock, Gulf of Mannar, India
An assessment of coastal pollution was made on the basis of trace element concentrations (arsenicClearing the air: 30th anniversary of the convention on long-range transboundary air pollution
The UN Economic Commission for Europe (UNECE) has released a brochure titledPotentialities of water resources pollution of the Nile River Delta, Egypt
The population growth, economic development with the consequent anthropogenic activities at the Nile Delta of Egypt addresses the present-day hydro-environmental status and quality deterioration trends of surface Nile River water. The hydrochemical fingerprints of surface waters revealed the effects of points and non-points sources of pollution. The relative low Cl- …Subterranean leak
25 years after the gas leak, another tragedy is unfolding in Bhopal reveals this latest study by Centre for Science & Environment. This study based on CSE's Pollution Monitoring Laboratory tests found that water and soil in & around the Union Carbide factory are loaded with pesticides. To know more …Groundwater slow poison in Bhopal'
Twenty-five years after Union Carbide's accursed chemical plant spewed 42 tonnes of poisonous methyl isocyanate (MIC) gas, killing 8,00010,000 people, and debilitating thousands of others, a study conducted by the Delhi-based Centre for Science and Environment (CSE) has found that toxic waste lying at the plant premises still contaminates the …Effect of source of nutrition on heavy metals in plants and soils
Agricultural practices, which add heavy metals to the soil, include indiscriminate use of fertilizers through chemical farming and plant protection chemicals. However organic farming is a production system to produce chemical free nutritious food of high quality. Organic farming is a production system, which avoids or largely excludes the use …Contamination of soil and water inside and outside the Union Carbide India Limited, Bhopal
25 years after the gas leak, another tragedy is unfolding in Bhopal reveals this study by Centre for Science & Environment.
