The conditions like high illiteracy rate (49.5%), poverty (PCI less than Rs 100 per month, 52.2%), poor housing (mud houses, 66.7%) unsafe water supply (78.6%) were prevailing in the surveyed population. The high respiratory morbidity may be attributed to high prevalence of smoking andprolonged inhalation of organic dusts during farming operation associated with illiteracyand poor socio-economic status. Gastrointestinal disorders were related to poor hygienic conditions, smoking and consumption of contaminated water. The symptoms pertaining to CNS, skin and eyes were found to be associated with exposure to pesticides展开更多

Depending on the quality of its source, water will almost certainly have to be treated to make it safe to drink. All water supplies for human consumption must be well stored, free from micro-organisms, parasites and any substances that endanger public health if found in sufficient numbers or concentrations, in the same time. In our continued effort for a better result in our study of qualitative aspects, by physicochemical and bacteriological analysis, the authors focus in two crucial questions： a） is the water quality of Sidi-bel-Abbes good or bad ,and well stored？ b） is the people of Sidi-bel-Abbes are aware of the importance of water and knowledgeable about how to use this vital？ This study is the first to use data from I real work based upon a developed method and a good investigation to know exactly if water of Sidi-Bel-Abbes is safely treated, well stored and consumed in resemble way. In first, the authors plotted the method in analysing the qualitative aspect of water using developed material for a precise result starting by the distribution connection （condition and management） and the verification of water tank storage and finishing by analyzing the all the aspect of water （physicochemical and bacteriological analysis）. In second, the authors focus on the way that people of Sidi Bel Abbes used and consumption water by introducing a targeted method （questionnaires） which help us a lot to know precisely the way, time and the real quantity of water consumed daily. In final step of our study of qualitative aspects, by physico-chemical and bacteriological, and environmental analyses, investigation processed by PCA （principal component analysis） of the drinking water supplied to Sidi Bel Abbes city （Algeria north-west） concluded by an encouraging result, that despite the various constraints faced by the departments concerned, they ensure the supply of safe drinking water in households almost daily.展开更多

To do this, the mapping of the different work areas made it possible to identify all the activities within the framework of the farm. Based on the mapping, environmental measurements made including noise level, brightness, electric and magnetic fields, total particles, PM10, PM2.5, PM1 showed the work areas with the exposure limit values exceeded. The inventories of the waste produced show eighteen (18) types of waste, 67% of which are special industrial waste (SIW), 28% are ordinary industrial waste (OIW) and 5% are inert industrial waste (IIW). The identification and assessment of environmental aspects and impacts made it possible to determine sixteen (16) positive and negative significant environmental aspects (ESAs). The positive AES must be maintained, and for the negative ones, mitigation and mitigation measures must be put in place in order to manage them effectively. This will ultimately improve environmental management in the operation of hydroelectric structures and facilities.展开更多

Rice is one of the most important agricultural products and it is cultivated in almost all countries in the world. Its production requires usually large flooded areas. Under these conditions, many greenhouse gases are generated, such as carbon dioxide, methane, nitrogen oxides and its derivatives. Cultivation of rice is responsible by the release of relevant amounts of these gases and contributes decisively to global warming. In this sense, the major points described here are general environmental aspects, the mechanisms of production of greenhouse gases, bioremediation, mitigation using other techniques and possible improvements of the cultivation by fertilizers and chemicals.展开更多

ISO 14040 recommends use of the technique in numerous areas of environmental management such as in designing for the environment, eco-labelling, environmental communications and the assessment of the effects of environmental activities. Despite being theoretically feasible, certain applications of the ecological assessment of a life cycle such as the possibility of identification and evaluation of environmental aspects with the use of LCA are, in practice, still new to many environmental managers. With its strong points, the technique seems to be a valuable tool, especially in the context of apparent concepts of Product-Oriented Environmental Management Systems (POEMS). In order to verify the hypothesis, the author decided to verify the level of use of LCA in the area of identification and assessment of environmental aspects in selected organizations. Therefore, questionnaire interviews were conducted with representatives of selected Polish and Swedish enterprises who, at the time of the interview, had certified environmental management systems. The organizations were analyzed with respect to applied methods and techniques used for identification and assessment of environmental aspects as well as the degree of use of LCA both in this respect and in other areas of environmental management. This paper will present the results of this research and conclusions.展开更多

This is the case in particular where knowledge of the true health consequences of environmental exposure to given risk factors are incomplete or its action is within the range of values where we do not anticipate the measurable biological effect. This applies not only in the case of the indoor environment related complaints but also to that of non-ionizing electromagnetic radiation and electroionic microclimate, among many others. A serious consequence found in the syndrome of mass hysteria is the fact that due to differently motivated information and disinformation, part of the population can suffer from psychosomatic symptoms and deterioration quality of life for those affected.展开更多
