Water Pollution Index
Opis:: This paper deals with the problem of environmental impact of metallurgical enterprises on ecological state and water quality of the Kalchyk and Kalmius rivers and the coastal zone of the Sea of Azov (Ukraine). These metallurgical enterprises Azovstal Iron & Steel Works and Ilyich Iron and Steel Works are situated in Mariupol city within the catchment area of the examined water bodies.
W artykule przedstawiono analizę wpływu zakładów hutniczych na stan ekologiczny i jakość wody rzek Kalczyk i Kalmius oraz strefy przybrzeżnej Morza Azowskiego. Zakłady hutnicze Azovstal Iron & Steel Works oraz Ilyich Iron and Steel Works znajdują się w Mariupolu i są usytuowane w zlewisku badanych akwenów wodnych.

Opis:: Various activities such as farming, industry, household waste, fish pond, and fishery can possibly affect the estuarine and coastal ecosystem. Demak waters, located to the east of Tanjung Emas Semarang, become an influential element of fishery industry that mostly produces anchovies and shrimps. This research was aimed at (1) analyzing the spatial distribution of heavy metal Pb and Cd in the surface water and sediment; and (2) investigating the abundance of coliform in Demak waters. Moreover, in this research, water pollution index was also analyzed and compared to other polluted water areas. It was found that the Pb content ranged from 0.6037 to 0.6647 mg·1^–1 whereas the Cd content ranged from 0.064 to 0.1707 mg·1^–1. Both lead and cadmium contents had surpassed the water quality standard. The Pb content in sediment ranged from 0.563 to 0.6823 mg·kg^-1 whereas the Cd content reached 0.0047 to 0.0577 mg·kg^-1. It showed that this sediment was not polluted by Pb and Cd. The analysis of water pollution index revealed that the pollution level found in Morosari, Rejo, Tuntang, and Lohbener estuary was low. On the other hand, Wedung and Serang estuary were heavily polluted. Compared to some previous studies, most of Pb and Cd contents in Demak waters were greater. However, lead and cadmium content in sediment was lower.

Opis:: Surface water is subject to strong anthropogenic pressures caused by the development and the extension of the agricultural activities and also by the industrial and domestic activities. Pollution is a major environmental problem due to discharges into rivers and the excessive use of agricultural fertilizers add to that the discharges from urban and industrial sources. The aim of this study is to assess the quality and the state of the organic pollution of surface water in the Kébir wadi east, based on the Water Quality Index (WQI) and the Organic Pollution Index (OPI) during six sampling campaigns carried out between April and September of the year 2011. Seven stations were studied along the Kébir wadi east downstream from the Mexa Dam. The results are visualized by the use of GIS through making thematic maps. They revealed that half of the stations show excellent to good water quality and moderated organic pollution except the stations S3, S6 and S4, that have poor water quality and high pollution at S3 and S6 respectively, and non-potable water with very high organic pollution at S4. The anthropogenic environmental deterioration recorded in the wadi is the result of the use of nitrogen and phosphate agricultural fertilizers and especially, the discharge of untreated domestic and industrial wastewater from neighbouring agglomerations. The seasonal variation remains discrete and reflects a slight tendency to the deterioration of the waters of El Tarf region during the low waters of the summer period.
