Soil Pollution - Causes and Effects

Effects of heavy metal pollution on the soil microbial activity

The effects of heavy metals on soil microbial processes were investigated over a period of six weeks. Analytical grade (Sigma) sulphate salts of copper, zinc and nickel were added individually and in combinations to soil samples and incubated in different plastic pots. Samples were taken from the pots forthnightly and the rates of microbial carbon and nitrogen mineralization, microbial biomass ...

Effects of Soil Pollution on Geotechnical Behaviour of Soils

Ground pollution arises from the impact of past and current industrial activity and due to improper disposal of waste generated by society. Geoenvironmental engineering deals with the most important aspects: (a) Soil pollution processes and effect on geotechnical properties, and (b) Waste Management. Soil-pollutants interaction changes soil behaviour and also can lead to various geotechnical pr...

Air pollution and causes of death.

This paper describes a study of the relationship between indices of air pollution and respiratory and other causes of death in the large towns of England and Wales.* Although there are now well over a thousand instruments measuring air pollution in one way or another in England and Wales, grave difficulties are involved in using their results to measure the average exposure to pollution experie...
