Adaptation technologies and legal instruments to address climate change impacts to coastal and marine resources in Tanzania
The increase in greenhouse gases in the atmosphere and the consequent pressures related to climate change are having significant impacts on the coastal and marine resources on which much of Tanzania’s coastal population depends for its livelihood. A decline in mangrove cover, coral bleaching and mortality and the destruction of seagrass beds are some of these impacts. Coastal erosion also poses threats...

Remediation of anthracene in mycorrhizospheric soil using ryegrass
Rhizosphere bioremediation has become an effective technique that uses green plants to enhance biodegradation of persistent organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), pesticides and radionuclides. Polycyclic aromatic hydrocarbons, due to their hydrophobic nature were found to be retained in the soil. Plants could be grown at the PAH contaminated sites to stimulate the biodegradation...

Effect of electroplating industrial waste on “available phosphorus†of soil in relation to other physico-chemical properties
Unorganized land disposal of industrial wastes contaminates land and ground water. The Wazirpur Industrial area of Delhi, a metropolitan city, generates highly acidic (pH 2 - 3.8) and toxic waste, and disposal remains a perpetual problem. This waste contains a high quantity of macronutrients as well as heavy metals because major industries are involved in metals finishing. Wastes of these industries were...

Occurrence of elevated nitrate in groundwaters of Krishna delta, India
Nitrate concentrations were measured in the groundwater samples of Krishna delta, India. The results indicate a large variation of nitrate from 10 - 135 mg/l. In 79 groundwater samples, about 39% shows high nitrate contents (>50 mg/l), which is more than the permissible limits in drinking water. In north Krishna delta 49% and in south Krishna delta 26% water samples were found to exceed the permissible...
