Concentrations of many trace elements in the environment have been significantly affected by man’s activities. The present study was made to evaluate the potential effects of ambient air pollutants (SO2, NO2, CO and PM10) on Calotropis procera and soil in Helwan city. The study also aimed to evaluate the damaging effect of human activities on soil and some plants, where samples would have collected from industrials, traffic and domestic sources in Helwan city. Sampling and measurements were based on the environmental protection agency (EPA) and the American Standard test methods (ASTM). Evaluation of air pollutants (SO2, NO2, CO and PM10) was measured by Miran Gas Analyzer and Thermo Dust Meter. It was found that all metals were belonging to very high contamination category at all sites near the factories except iron. the internal parts of the leaf and shoot in the Calotropis procera are not affected by concentrations of air pollutants found in Helwan industrial area air or even high concentrations in soil","PeriodicalId":211739,"journal":{"name":"International Journal of Advanced Research in Biological Sciences (IJARBS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125693039","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}

Transgenic technology has been used to increase crop yields and improve their nutrition, reduce the use of pesticide and herbicides by making them tolerant, insect resistant, reduce CO2 emissions, and decrease the cost of crop production. However, since the first GM crop produced, thedebate of using/not using GMO crops is ongoing. A number of concerns like toxicity and allergenicity to animals and humanbeings, potential environmental risks, such as chances of gene flow, adverse effects on non-target organisms, evolution of resistance in weeds and insects etc. have been the major roadblocks in its application. In this review, we present a comprehensiveupdate on the current status of the genetically modified (GMO) crops under cultivation. We also discuss the issues affectingwidespread adoption of transgenic GM crops and comment upon the recent tools and techniques developed to address some of these concerns.
