Pesticide waste leachate toxicity evaluation and hazard quotient derivation by Allium assay
This study was envisaged to explore the impact of pesticide solid waste leachate to Allium cepa (common onion) bulbs. Bulbs exposed to the leachate showed hampered root growth and morphological deformities. At 15% and higher concentrations of leachate after 5 days, gall like swellings were noticed around the mitotic zone (zone of root growth). From the dose response curve, the EC50 values for t...
متن کاملGenotoxicity of pesticide waste contaminated soil and its leachate.
OBJECTIVE Improper land disposal of hazardous waste can result in leaching of hazardous constituents which may contaminate ground and surface water leading to adverse impact on human health and environment consequences. The present study utilized mammalian cell culture for the genotoxicity assessment of waste and its leachate. METHODS Genotoxic potential and chemical analysis of pesticide der...
متن کاملToxicity identification evaluation of landfill leachate taking a multispecies approach
In this study, the first phase of Toxicity Identification Evaluation (TIE) was used to characterise the major toxicants present in a Malaysian landfill leachate, using multispecies bioassay. Freshwater fish (Rasbora sumatrana), freshwater prawn (Macrobrachium lanchesteri) and tomato seeds (Lycopersicon esculentum) were chosen as test species based on local availability, as well as their broad s...
متن کاملAssessment of Municipal Solid Waste Landfill Leachate Treatment Efficiency by Leachate Pollution Index
Leachate pollution index (LPI) value can be used as a tool to assess the leachate pollution potential of landfill sites particularly at places where there is a high risk of leachate migration and pollution of groundwater and thus can help to take necessary decisions as deem fit. In this paper, leachate treatment efficiency was evaluated on the basis of LPI value of leachate before and after tre...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
