Sanitation without pollution. 卫生无污染。

{"title":"Sanitation without pollution.","authors":"U Winblad","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The most effective way of protecting drinking water resources from domestic sewage is to use technologies that do not produce sewage. This paper gives an overview of emerging alternatives in the form of ecological sanitation systems for urban and peri-urban areas. A key feature of ecological sanitation is that it regards human excreta as a resource to be recycled rather than as waste to be disposed of. Examples given include ecological sanitation systems based on dehydration and decomposition from Mexico, El Salvador, Sweden, India and Vietnam. These systems need neither water for flushing, nor pipelines for transport, nor treatment plants and arrangements for the disposal of toxic sludge. Large scale application of ecological sanitation would lead to less environmental pollution, reduced water consumption, considerable savings on sewers and treatment plants and increased employment. In addition it would provide valuable resources for food production and wasteland development.</p>","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"269-74"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unused medications are sometimes disposed of in drains. The drugs may enter the aquatic environment and eventually reach drinking water, if they are not biodegraded or eliminated during sewage treatment. Additionally, antibiotics and disinfectants are assumed to disturb the wastewater treatment process and the microbial ecology in surface waters. Furthermore, resistant bacteria may be selected in the aeration tanks of sewage treatment plants by the antibiotic substances present. Since the 1980s, data on the occurrence of pharmaceuticals in natural surface waters and the effluents of sewage treatment plants have been reported. More recently, pharmaceuticals have been detected in ground and drinking water. However, only little is known about the risk imposed on humans by pharmaceuticals and their metabolites in surface and drinking water. An overview of input, occurrence, elimination (e.g. biodegradability) and possible effects of different pharmaceutical groups such as anti-tumour drugs, antibiotics and contrast media as well as AOX resulting from hospitals effluent input into sewage water and surface water is presented.</p>","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"59-71"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the principles of the South African National Sanitation Policy stipulates that sanitation systems which have unacceptable impacts on the environment cannot be considered to be an adequate form of sanitation. The greatest contamination concern with respect to ventilated improved pit toilets is in relation to groundwater resources. To this end the National Sanitation Co-ordination Office (NaSCO) and the Directorate of Geohydrology of the Department of Water Affairs and Forestry have developed \"A Protocol to Manage the Potential of Groundwater Contamination from On-Site Sanitation\". The aim of the protocol is to ensure that reasonable measures are taken to guard against contamination of valuable groundwater resources by inappropriately located or designed sanitation systems. The protocol focuses on dry on-site sanitation systems and provides a brief background to the current understanding of groundwater contamination by on-site sanitation systems. It also presents a procedure to be followed by those involved in implementing new, or upgrading old systems--the procedure allows the field worker to assess whether groundwater resources may be at risk of pollution. The protocol is specifically aimed at engineering and technical staff who are not groundwater specialists.</p>","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"95-8"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diarrhoea and other water related diseases are the major causes of health problems in developing countries. Although the need for water and sanitation interventions for health promotion has been recognised, these are labeled as costly and are often neglected in the primary healthcare programmes. Lack of proper water and sanitation initiatives based on appropriate techniques, technologies, knowledge and/or implementation methods have hindered the expected achievements through water and sanitation interventions. Since water and sanitation initiatives include both availability of provisions and their effective use (which mean behavioral changes), they are technically and socially challenging. Disasters and emerging water quality problems, such as arsenic in groundwater, have further been complicating this situation. After reviewing relevant articles, several research issues are suggested in the context of developing country perspectives.</p>","PeriodicalId":76530,"journal":{"name":"Schriftenreihe des Vereins fur Wasser-, Boden- und Lufthygiene","volume":"105 ","pages":"47-52"},"PeriodicalIF":0.0,"publicationDate":"2000-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21686993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
