ARSENIC III TOLERANCE POTENTIAL OF FUNGI ISOLATED FROM POLLUTED AND NON-POLLUTED SOILS OF PAKISTAN
...acity. In present study, arsenic (As) tolerance of indigenous filamentous fungi was explored. Fungal strains were isolated from peri-urban soils of Multan and Gujranwala irrigated with untreated industrial or municipal effluent. Some fungal strains were also isolated from non-polluted soils of Islamabad area. Arsenic (III) tolerance potential of 18 fungal isolates was tested by growing them on Potato Dextrose Agar (PDA) medi...

agent. Present research work is focused on the teratogenic impacts of sodium
arsenate given to gravid mice (Mus musculus). Different doses of sodium arsenate
18.25, 37.5 and 75mg/kg B.W. were administered orally at day 6 of gestation

Alcaligenes spp. N27 and Lysinibacillus spp. P17 showed strong activity against all the three ATCC strains. The study concludes that the bacteria isolated from the rocks having substantial resistance to heavy metals are also showing good antibacterial activity...

...us issue now a days. For arsenic removal batch studies were conducted using low cost adsorbent (raw date seeds husk and lemon juice microwave activated date seeds husk) by taking 25ppm/50ml initial concentration of NaAsO2. Best removal (90%) was achieved for Lemon juice microwave activated date seed husk LMDS (time= 30mins, agitation speed= 150 rpm, pH= 5, adsorbent dose= 0.1 g). While 85% removal efficiency was observed for Raw date seed husk RDS (time= 4...

Overall, the average levels of Cd, As and Ni (31, 20, and 37 ng/m3) were lower indoors as compared to outdoors (39, 21, and 51 ng/m3) except Pb. The high indoor levels of Pb (113 ng/m3) as compared to outdoors (85 ng/m...

AN INVESTIGATION OF HEAVY AND TRACE ELEMENTS IN COAL DEPOSITS OF MAKARWAL PAKISTAN AND THEIR POSSIBLE IMPACTS ON SURROUNDING WATER-CASE STUDY
...these coalfields contain arsenic (As) ranging from 3.0–16.34mg/kg, cadmium (Cd) 2.23–4.61 mg/ kg, Co 22.1–29.3 mg/kg, Cr 113.1–288.2 mg/kg, Cu 8.53–23.2 mg/kg, Fe 1133–10813 mg/kg, Ni 44.35–148.8 mg/kg, Pb 18.49–46.25 mg/kg and Zn 25–242 mg/kg. Moreover, the Mk-D coal samples had the high concentration of Ni, Cr, As, and Cd. However, the coal samples from Mk-C had higher contents of Cu and Pb. Whereas,...

Twenty Wistar rats were used for this study; one group was normal control (NC), second group was exposed to ATO only while the other two groups received metformin (MF) and RSV separately along with ATO. We measured serum levels of glycemic index biomarkers and carbohydrate metabolizing enzy...
Heavy metals (HMs) are harmful and lethal at negligible levels and non-biodegradable in the typical ecosystem and constitutes animal, human and environmental hazards. They are divided into toxic metals like Lead, Cadmium, Arsenic, etc. and essential elements like copper, zinc, manganese, iron, nickel and chromium. Additionally, could be categorized into two groups based on the natural and anthropogenic sources releasing origins. Population and industrial expansion led to food contamination with HMs. Poisonous metals can be transferred from irrigation water to agricultural soils, agricultural operations, air pollution, animal feed, and packaging materials. Toxic metals are non-biodegradable, non-thermos degradable, and exceedingly stable in the ecosystem; as a result, they quickly build in various foods. Metal pollution of many foods, including agricultural commodities, and animal protein sources such as fish, milk, meat, and eggs, poses a hazard to food safety and security. Toxic metal pollution of irrigation water, agricultural soils, plants, and animals result in their integration into the food chain, posing a health hazard to humans. Most metals are harmful to animals and humans and accumulate in several organs like the skeleton, hepatic tissue, spleen, and renal tissues. Metals have a deleterious impact on the production of plants and animals. As a result, several remediation strategies have become necessary to limit the hazardous HMs pathway into the food chain and the human body. Metal nanoparticles are employed in beneficial applications, although they are associated with specific hazards.
