Heavy metal pollution is of particular concern as they have deleterious effects on biota through mobilization and accumulation in various trophic levels. The present study mainly focused on the water pollution by heavy metals in Cochin estuary and two adjoining rivers. The methods include seasonal collection of surface water from the study area and their subsequent heavy metal analysis. The stu...

The large quantities of slurry and manure that are produced annually in many areas in which cattle are raised could be an important source of organic matter and nutrients for agriculture. However, the benefits of waste recycling may be partially offset by the risk of water pollution associated with runoff from the fields to which slurry or manure has been applied. In this paper, the effects of ...

The prevalence of various pollutants like nitrogenous, sulphurous, phosphorous compounds, heavy metals, and organic compounds has seriously threatened the sustainability of natural ecosystems and is thus interfering with the natural biogeochemical cycling. Chemical pollution of water bodies can cause serious damage to environmental quality because many of these pollutants are extremely toxic an...

We propose a water pollution source mapping system based on ubiquitous sensor networks that fish robots search the source of water pollution autonomously. To verify the effectiveness of a water pollution source mapping system, we made a model water pool in which a fish robot pursues infrared measurements of reflection to various colors at the bottom of the pool. The model of water pollution con...

pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. therefore, the aim of this study is evaluation of citizens’ attitude towards water and soil p...

Effluent from the textile industry contains toxic compounds. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water bo...

Lack of sewage collection systems, percolation of surface waters, and seepage of wells have raised the groundwater table in Shiraz area in the south of Iran. The growing population generates environmental pollution resulting in the degradation of the quality of surface and groundwaters used for agriculture. Inorganic and organic pollutants have been traced in Shiraz water resources. Heavy metal...

Water is a valued natural resource for the existence of all living organisms. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution in the Unity Road stream segment of Asa River in Ilorin, Nigeria. Juvenile samples of Clarias gariepinu...
