Enormous number of contaminants and waste materials containing heavy metals are disposed into the biosphere. Remediation of heavy metal contaminated sites using chemical or physical techniques is the most challenging task. Phytoremediation can be used as an alternative remediation and cleaning up techniques. The aim of our research was to identify some interesting accumulators which may associate an important biomass production with an effective absorption and translocation of heavy metals. Among the analyzed heavy metals, Cr had the highest concentrations in all the sampling sites, while Cd had the lowest concentrations. Sediment concentrations in the industrial area are characterized by the high values of Cr and Ni. For phytoremediation purpose Datura inoxia and Lantana camera were studied for in vitro culture and there parameters were compared. The present paper describes a prime and easy-to-use protocol for large scale production of plantlets through shoot tip culture of Datura inoxia, the plant having phytoremediation potential and the method is useful for the ex-situ conservation of other phytoremediational important species.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"58 1","pages":"40-55"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73084586","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}

Results obtained for the control experiment indicated biodeterioration of the crude oil sample. This was evident from the variation in the values of BOD, THC, TMC and pH indicating the presence of microbial activity. Results obtained also showed that biodeterioration was mitigated when antimicrobial agents were introduced to the crude oil samples as seen in the stability in the values of BOD, THC, TMC and pH.

The chemical substances transferred in soil profiles is a major environmental concern because even slow transport through the soil may eventually lead to deterioration of groundwater quality. The study reveals the physico-chemical characterisation of soil horizon of agricultural field which was regularly irrigated with distillery effluent for the observation of leaching effect of distillery effluent in soil horizons and ground water quality. The result showed that all the physico-chemical properties of soil horizons have high content of effluent irrigated soil compared to fresh water irrigated soils. It may be concluded that the higher value and indiscriminate use of distillery effluent on land affects the composition of the soil and groundwater quality due to leaching. The soil horizon showed higher value in surface soil while the values were less in lower soil horizons as compared to unaffected soil.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"85 1","pages":"63-73"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83487502","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}

The design of proper system to meet specific requirements relays on selection of different filtration components. Components are available in a wide range of designs to meet various requirements of air filtration level, quantity, and characteristics of the contaminants to be removed. An expert system package for the selection of dust collectors' components is developed. The developed package utilizes database as well as knowledge base to aid the selection process based on practice and past experience. Industrial case studies are demonstrated to test the developed package and compare its results against the current systems design. The developed package in one case study estimated a minimum air flow rate of 60000 m 3 /hr, which is 30% higher than the existing value and a static pressure drop due to ducts of about 1900 Pa which is 30 % lower than the current value leading to improved air quality. In another case study the package results indicated the need to minimize the value of air flow to be 2300 m 3 /hr, which is 50% lower than the current value and increase the external static pressure to 1700 Pa which is 70% higher than the existing design value leading to better filtration efficiency.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"1 1","pages":"14-28"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79467948","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}

The Markov-cellular automata model is an important and powerful tool in simulation. In this article a new Markov-CA model was developed based on built-in multi-regression model and multi-criteria evaluation approach to improve the representation of Markov-CA transition rules. Utilised data relate to the environmental and socio-economic are produce criteria layers and weights in order to output the suitability maps via a ranking method for periods 1984, 1990, 2000 and 2010, which have become conditional for the next step of Markov-CA generation. The suitability maps are compared in order to determine the best fit maps based on the values of the root equation (R 2 ). This comparison helpful to the stakeholders make better decisions and the best maps indicated best transition rules, which is represent the core of Markov-CA model. Thus, the resultant of best suitability maps derives a predefined transition rule for the end of Markov-CA model step. The approach used in the present study a mechanism for monitoring the land-use and land-cover changes in Kirkuk depend on Markov-CA is implemented and evaluated thru the different decision maker. The results assert that the model bears a high applicability and flexibility degree in land-use and land-cover changes.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"76 1","pages":"29-42"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80520347","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}
