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...

Decisions about water pollution control and management in river systems are increasingly based on predictions made with water quality models. Many uncertainties are associated with the development and calibration of such models and thus affect the model predictions. Therefore it often is necessary to perform a model reliability analysis prior to or as a supplement to model application to water ...

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...

Berenyok river is one of the water sources in Tanjung Karang, Mataram city, categorised as Class 2 for its designation. Thus, preserving quality crucial. This study aims to determine quality, calculate Pollution Index (PI), and set control strategies river. The uses quantitative methods such laboratory analysis PI calculation using a formula based on Decree Minister Environment No.115/2003 dete...

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...

fifty percent of world argricultural production is destroyed by insects each year. therefore, enormous quantities of insecticides are consumed to control these pests. as an example, france is using 35000 metric tons insecticide every year. some of the methods used for spraying and applying insecticides tend to increase the pollution of natural waters . in this article different factors causing ...
