Candida Albicans as an indicator of pollution in estuarine waters in Pollution and water resources. Pollution, coastal biology and water resources selected reports.
This book summarizes research on the distribution and causes of arsenic pollution in nature, its impact on health and agriculture, and the encouraging research that offers hope in mitigating this health crisis. The book provides information
on the geographical distribution of arsenic contamination of groundwater and of surface water, the geochemical causes of high arsenic concentrations in aquifers, and the health implications of prolonged arsenic ingestion. Options are highlighted for developing
alternative water sources and methods for arsenic testing and removal. - (HC)

A complex evaluation of the development of water quality in the Berounka River basin during the 1990s. The main influencing factors of pollution are the surface water. The main affluents - Střela, Litavka, Třemošná, Rakovník and Kaznějov creek
, remain even under the heavy influence of intensive pollution of communal and agricultural origin. - (MS)

This paper gives a short overview about the hydrological conditions of Hungary with special attention to water budget and water quality problems. It begins with an overview to what extent Hungary is dependent on water, then the water budget
of the country is described with special reference to the interests of agriculture and reservoir capacities in the various regions. The second half of the paper focuses on the contamination problems of surface and ground water bodies. - (JS)
The protection of karstic water and confined water under pressure is of special importance, because surface waters and near surface groundwater are already polluted in major areas. Sensitivity of pollution is graded by the A. on hydrological

With rapid development of socio-economy and urbanization, many new small towns have occurred in China, and the concerned ecological problems such as waterpollution and soil erosion have been gradually changed into local point source pollution
. The Research Center of Water Problems undertook a research project of comprehensive planning of urban environment of Changli County, Hebei Province. The planning is aimed to protect and to improve the environment with the least cost, to promote the suitable

Field sampling in the Basins of the Yaguez, Cibuco and Guayanés Rivers revealed that their waters are heavily contaminated with coliform bacteria, nitrogenous compounds, heavy metals and semi-volatile organic compounds. The AA. believe this degree
of pollution calls for immediate environmental reform on the island. - (DWG)
