The pollution loads have been calculated and compared by considering usage of the Compressed Natural Gas (CNG) in place of conventional diesel buses. In this study, the Karnataka State Road Transport Corporation was considered and collected the required information such as the total number of buses, daily kilometres operated by the KSRTC buses. These buses run on diesel fuel and are responsible for largest amount of lead emissions and various other pollutants. The pollution loads calculated on the basis of information collected from the Central Pollution Control Board (CPCB), Environment Protection Agency and previous studies carried out in this regard by various important agencies. The use of CNG shows tremendous reduction in various pollutants in gm/km. By the use of CNG we can find 84% reduction in CO, 58% reduction in NOx and 97% reduction in PM.","PeriodicalId":13706,"journal":{"name":"International Conference on Green technology and environmental Conservation (GTEC-2011)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90973015","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}

But the textile dyeing industries has been condemned as being one of the world's most offenders in terms of pollution. Bangladesh has now become a significant supplier of Readymade Garments to both North America and Europe. More than 50% of Bangladeshi garment exports go to European Union and 44% to the USA. There are many dyeing industries in our country which are mainly located at Gazipur and Narayanganj industrial area. This study was aimed at the dyeing industries in Bangladesh to assess the present situation of environmental impacts arises from such activities and propose several mitigation measures. This was done by analyzing numerous data obtained from different laboratory test concerning a range of water quality parameters of Bangladesh. Important water quality parameters like pH, turbidity, TSS (total suspended solids), BOD, COD and presence of metals like copper, cadmium, mercury, arsenic, etc. were measured by testing samples. The samples were collected from effluent water of a renowned and international buyer (like GAP, PUMA, and LEVI's) recognized industry named UNIQUE Washing and Dyeing industry Limited at Gazipur, Dhaka. The results show that all the water quality parameters are within the permissible limits. Though the water test report shows no vulnerable change in water quality for this particular industry, but the overall EIA report shows the highest negative impact on physico-ecological environment. The human interest related factors make the total EIV positive.","PeriodicalId":13706,"journal":{"name":"International Conference on Green technology and environmental Conservation (GTEC-2011)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87205541","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}

Their occurrence in the environments leads to different allergenic diseases viz., allergic asthma, bronchitis, rhinitis, and hay fever in the atopic human beings. The present study is an attempt to record the incidence and seasonal periodicity of airborne fungal spores in indoors and outdoors of an industrial city house, Hosur, Tamilnadu by Petri-plate settlement method from October 2009 to September 2010. In qualitative and quantitative way, fungal spores considerably varied from indoors to outdoors as well as from season to season. Outdoor air harbored maximum fungal spores (54%) in comparison to indoor air (48%). Incidence of fungal species was predominated with more number of propagules during mid winter (December) and early rainy (July) periods in comparison to other months. Qualitatively, Aspergillus was found with the highest frequency and had eleven members i.e., A. awamori, A. fumigatus, A. niger, A. flavus, A. flavipes, A. nidulans, A. ochraceous, A. japonicus, A. terreus, A. versicolor and A. wentii, but quantitatively, Penicillium was isolated highest in its contribution to total CFUs followed by Aspergillus. Out of the 32 isolated fungal taxa, Aspergillus fumigatus, A. awamori, A. niger, Rhizopus stolonifer and Alternaria alternata were the predominant aeroallergens, which cause different types of respiratory/lung diseases in atopic human beings. In seasonal periodicity, winter contributedthe maximum spore load followed by rainy and summer was found with the least in harboring the spore mass in the indoors and outdoors. Alternaria alternata, which is accounted as a human allergen for sporosis inducer and an agent for hay fever and other pathologies, was also intermittently recorded. A few plant pathogenic, saprophytic, field and storage fungi were also recorded during the study period. Effect of meteorological parameters on the fungal spores in the dwelling atmosphere was significantly assessed by Pearson's correlation coefficient analysis.","PeriodicalId":13706,"journal":{"name":"International Conference on Green technology and environmental Conservation (GTEC-2011)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73834752","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}

Rajan","doi":"10.1109/GTEC.2011.6167642","DOIUrl":"https://doi.org/10.1109/GTEC.2011.6167642","url":null,"abstract":"So, it is clearly evident from the above discussions, the researcher came to understand that the stipulation of both environmental standards and the development of energy saving culture in the spinning industry was depended on the availability of necessary pollution control strategies in the industry, installation of cleaner and energy efficient technology, implementation of extended supply chain practices, management and handling of modern technology which were used in controlling pollution and utilization of energy resources. Apart from these, the pollution control enforcement agency should monitor the pollution emitting industries and should prescribe the environmental standards exclusively for spinning industries. Since the TSPCB has not yet prescribed any separate environmental standards for the spinning industry, it is difficult to assess the optimal environmental standards to the selected spinning industries. Among these, there is no any uniformity in the available infrastructure facilities and technology used for energy saving and pollution control techniques. It was also found that the techniques used by the industries differ from each other. From the broad and extensive research work conducted by experts, the researcher understand that there were many energy saving and pollution control techniques like compressed air leakage- detecting techniques and humidity control mechanism etc. Which were used in the spinning industries located in other countries like China, Pakistan and Zimbabwe were absent in the selected industries. Therefore, the selected spinning sectors should try to introduce the latest technologies in controlling the liquid and air pollution and energy saving techniques. Since, the selected industries were medium level industries, they could not install or introduce any modern, sophisticated energy saving and pollution control technology. In this regard, these selected industries have to depend on the State and the Central Government's assistance to replace all the present outdated technology and introduce a new and innovative energy saving technology for pollution controlling plants. With these approaches and strategies, spinning sector can substantially contributing to the sustainable environmental and industrial development in Tiruppur and Virudhunagar regions.","PeriodicalId":13706,"journal":{"name":"International Conference on Green technology and environmental Conservation (GTEC-2011)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86721246","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}
