Bioremediation uses various microorganisms to detoxify or degrade various harmful substances in the nature, particularly soil and water. In the proposed work, five species of micro-organisms were used to analyse their impact on various physico-chemical parameters of water. In the first attempt the actual physico chemical parameters of the collected sample water were noted down (Fresh sample par...

In the present study the effect of sewage water and canal water irrigation were compared by their physicochemical properties and heavy metals concentration in soil. The mean values of different physico-chemical parameters and heavy metals were : Bulk density (gm/cm) 1.26, Water holding capacity(%)-53.60, Temperature(oC)-16.33, Electrical conductivity (dsm-1)0.122, pH-7.5, Organic carbon (%)-1.9...

Ground water is considered as a valuable resource for drinking, agricultural, and industrial uses. As human activities are known to affect water quality, studies of this source are necessary to maintain quality standards. Despite heavy agricultural and industrial activity in the Lenjanat region (Isfahan), there has been no evaluation of ground water quality in this area.In this research project...

Diverse industrial wastes have aggravated the problem of water pollution. This problem becomes complex because of the non-degradability of inorganic pollutants like heavy metals. Metals have received particular attention among other non-degradable toxic chemicals because of their adverse effects on aquatic life forms. To control water pollution, the immediate problems have to be solved by adopt...

An approach is presented to study the functioning of a karstic massif and assess the adverse effects of the anthropogenic pressure by monitoring some water chemical and physical parameters of its main springs. The approach has been applied to the Sette Comuni Plateau (Veneto Region, Italy) hosting a well developed karstic system, whose aquifer presents high vulnerability and undergoes a relevan...

In general, the history of environmental research is not known very well. Our study contributes to filling this gap by focusing on the history of the methods that were used during the 20th century to study the state of the urban sea area in Helsinki, Finland. From the beginning of the past century, the methodological basis of municipal water pollution studies in Helsinki was broad, involving th...
