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

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
