...f 16 polycyclic aromatic hydrocarbons (PAHs) in the flesh demonstrated that PAHs accumulation in the treated snails was fluctuated with time. The accumulation is due to their biotransformation process during metabolism. The histopathological observations of the gills and mantle of L. carinatus showed pronounced alterations at 24 hours and proliferated at the day 15 but showed a further decline at the day 30 of exposure. These findings seem to be time related a...

Present study is focused on production of biosurfactants from indigenous bacteria, isolated from produced water and produced water contaminated soil samples collected from three selected sites of Eastern Potwar, Punjab, Pakistan. Forty seven bacteria were isolated out of which five (F1, F3, F20, F23 and C16) were selected on the basis of high optical densities of 0.7, 70% oil an...

However, the adverse effects of cigarette smoke on other tissues are largely unknown. We explored the genotoxic effects of tobacco smoke on peripheral lymphocytes of active and passive smokers. Blood samples were isolated from 100 males’ including 25 active-, 25 passive- and 50 non-smokers. Alkaline comet assay was done and classes were ...

...s of polycyclic aromatic hydrocarbons (PAHs) and heavy metals in different types of marinated meat, such as beef, chicken, mutton and fish, and different grilling techniques were applied to see their effectiveness in lowering the levels of these toxicants. Polyaromatic Hydrocarbons and heavy metals refer to a large group of chemicals that may be present in the environment as pollutants and can enter the food chain and might ...

Methyl-(7Z)-7-hexadecenoate, methyl-(9E)-octadecenoate and methyl tetracosanoate were found to be the principal fatty acid esters, while E-pentatriacont-17-ene and 2,4-dimethylpentane were identified as predominant aliphatic hydrocarbon compounds. The propolis extract has exhibited remarkable antimicrobial activity against certain strains of bacteria and yeasts. In general, significant antimicrobial activity was recorded ...

A METHOD OF DATA MINING FOR SUSTAINABLE HYDROCARBON EXPLORATION
...erves. In Pakistan, hydrocarbons are considered to be one of the major sources of energy. The contribution of hydrocarbon to overall development will be considered sustainable only if the hydrocarbon exploration rate will conform to its consumption rate. To ensure sustainable energy development, sustainability indicators had been agreed by world experts in a summit held in South Africa in 2001. These indicators will have different valu...

Selective Capture of CO2 from Mixture of Different Gases using Cellulose Acetate, Polyimide, Polysulfone and some other Polymers based Mixed Matrix Membranes: A Review
...f CO2, methane and other hydrocarbons but mixed matrix membrane based separation is gaining significant importance day by day. A number of different polymers have been employed for the fabrication of mixed matrix membranes for example cellulose acetate, polyimides, polysulfone, pebax, polybenzimidazole, polymer of intrinsic porosity, polyurethane, chitosan and many more. Likewise, along with other fillers, Metal organic frame works have also been tested as add...

During both periods, the goats consumed a diversity of plant species. Milk collected from Kilis had 15.27-16.10% total solids,5.70-6.50% fat and 4.80-5.10% protein. The lactose content did not differ significantly between milk samples from the two locations (3.90-4.20%). Total unsaturated fatty acid levels were s...

Polycyclic aromatic hydrocarbons (PAH) and mono-aromatic hydrocarbons-benzene, toluene, ethylbenzene and xylene (BTEX) are chemicals derived from fossil fuels that easily get into the aquatic environment. These chemicals were investigated in the fish parasite Tenuisentis niloticus, as a reflection of the extent to which these compounds are present in the lagoon. One hundred (100) samples of Heterotis niloticus...

During the experimental study, the biodegradation efficiency of BaA was enhanced from 12.2% in the control to 25.6% at pH 10 and 46.7% at pH 10 and alkyl polyglucosides (APG) reactors. APG and alkaline treatment increased the BaA deposition desorption from the sludge and trans...
