Background and Aims: workers in petrochemical industries are exposed to various contaminants and are facing to serious hazards, therefore a comprehensive risk assessment program for identification of hazardous chemicals that affect human health and also determination of hazardous tasks and processes is necessary. Methods : This descriptive cross-sectional study was conducted in three stag...
In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...
Four crop plants Oryza sativa (rice), Solanum melongena (brinjal), Spinacea oleracea (spinach) and Raphanus sativus (radish) were grown to study the impact of secondary treated municipal waste water irrigation. These plants were grown in three plots each of 0.5 ha, and irrigated with secondary treated waste water from a sewage treatment plant. Sludge from the same sewage treatment plant was app...
ABSTRACT (#667537) Monitored natural recovery (MNR) was assessed as a non-invasive method for limiting residual oil exposure in the aquatic environment following contained spills of Cold Lake Blend diluted bitumen (CLB) and conventional heavy crude (CHV) at IISD-Experimental Lakes Area Canada. Oils were applied left place 72h to simulate potential spill cleanup response times. After physical re...
Freshwater prawns, Macrobrachium lamarrei (Crustacea-Decapoda) were subjected to static subacute exposure (0.755 mg/l) of detergent, Linear Alkyl Benzene Sulphonate (LAS) (25% 96h LC50) for 10,20 & 30 days. Hepatopancreas showed pronounced changes like vacuolization, hypertrophy, hyperplasia and degenerative leading almost complete loss histoarchitecture after days exposure. Peculiar cell shedd...
