The textile dyeing and washing industry plays an important role in the economical growth as well as the environmental sectors of Bangladesh, contributes significantly to the textile and clothing export trade. 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.

A Yield damage function helps to illustrate by relating yield damage and some independent parameters of soil such as top soil depth and organic matter content. This study was focussed on three tea growing district, Passara and Watawala sub district of Sri Lanka and the Nilgiris of India where considered 208 tea fields from Passara tea growing region, 52 tea fields from Watawala/Ginigathena tea growing region and 96 tea fields from the Nilgiris tea district covering 66 and 30 tea fields from TANTEA Plantations corporation and four private tea plantations respectively. The results of the study show that the Passara region is responsible for higher yield damage due to top soil reduction and the region shows very shallow soil depth and poor ecological condition. If the Nilgiris is in a condition to manage the issue, Passara tea region of Sri Lanka is required immediate actions to control the problem for sustainability of tea industry of the region.

An attempt is made to treat Industrial effluent using concentrated solar distiller with latent heat storage materials. Paraffin wax is used as latent heat storage material in the basin. For further augmentation of the yield by using sponges, pebbles and Mild steel billets are added to the distiller. Daily efficiency and percentage increase in productivity for these modifications are also studied. Industrial effluent water is used as feed. To settle the industrial effluent, a settling tank was also fabricated with five layers namely: tray for raw effluent, pebble layer, coal layer, sand layer and collection tray for settled effluent. Physical and chemical analyses were made for raw effluent, settled effluent and distilled water.

This paper deals with the exhaust emissions emitted by the Diesel buses of Karnataka State Road Transport Corporation and suggestions to reduce the emission levels by the use of an alternative clean fuel CNG. 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.

Microfungi are the main source of aero-biopollution in extra and intramural environment of most of the places worldwide. 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.

The PCs are playing vital role in our day to day life. But also in the same time it emits lots of carbon equivalent in the atmosphere it results in global warming. The major emission of carbons is by E-waste and heat emitted by the servers that are in datacenters normally we all know computer emits lots of heat especially servers. For example, searching servers emit lots of heat per search. In this Research paper we provide a solution from the birth of the pc to degradation including solutions for the heat produced by the servers and this paper gives solution for power consumption. It also provides role of cloud computing in controlling carbon emission and saving of carbon. Due to the power consumption we saved the heat generated from the power stations. Here we providing the solution using fuzzy logic based devices with their working principles and more on of Power consumption Techniques. One more key thing from our proposal is it does not need any huge amount of investment and it is profitable for that concern also.

Banana belongs to the family Musaceae with central East Asia as its centre of origin. India is rich in bio-diversity for these species but hazards of modernization are giving a threat to wild species of banana for their in-situ conservation. These species are good source of resistant genes for biotic and abiotic stress. Because of their female fertility, the seeds cam be made use of in conservation. But the seeds do not show consistent germination which involves lot of factors. Hence in this study an attempt has been made to study the seed germination behaviour and to improve the germination of banana seeds by treating with various hormones. Also embryo culture has been tried under different conditions. GA pretreatment of seeds has given good results under in vitro conditions.

Over exploitation of land, water, air and energy resources, as part of the urbanization and industrialization has forced the imbalance of the natural ecosystem. Millions of tonnes of various industrial wastes accumulated at different sites due to rapid industrialization cause severe damage to environment. Further, demolition wastes from constructed facilities also generate huge amount of wastes which include sand, gravel, concrete, stone, bricks etc, in India. Recycling of aggregate materials from construction and demolition waste and use of industrial wastes for production of useful building materials can fill part of the demand supply gap. This paper focuses the approach of recycle and reuse, wealth out of waste, for appropriate use of waste in the manufacture of building materials and how the industrial wastes like fly ash (from thermal power stations), blast furnace slag (from iron industry) and stone dust (from construction industry), rubber chips (tyre wastes) can be used in a passive way to the construction activity. This paper also presents zero energy approaches like, stabilized mud block for masonry, rammed earth wall, low intensity floor and roofing systems, construction and demolition waste as aggregate in concrete (recycled aggregate) to emphasis the green energy concept that can be adopted in construction industry and to overcome the energy crisis, a country like India is facing presently and forecast in the coming decade.
