The impact of heavy metal toxicity on the shoot and root lengths, total protein, fiber characteristics, moisture content nutrient composition spinach (Spinacia oleracea) was evaluated. Plants were grown in pots containing soil treated with different concentrations (mg/kg) lead (Pb; 300, 400 500), cadmium (Cd; 0.5, 1 1.5) zinc (Zn; 250, 500, 700) as well mixtures Cd Pb (0.5/300, 1/400, 1.5/500), Zn (0.5/250, 1/500, 1.5/700), (300/250, 400/500, 500/700). Soil contaminated by long-term...
The utilization of biochar, derived from agricultural waste, has garnered attention as a valuable material for enhancing soil properties and serving substitute adsorbent the elimination hazardous heavy metals organic contaminants wastewater. In present investigation, amide-modified biochar was synthesized via low-temperature pyrolysis rice husk harnessed removal Cr(VI) resultant treated with 1-[3-(trimethoxysilyl) propyl] urea to incorporate an amide group. characterized by employing Fourier...
A highly efficient low-cost adsorbent was prepared using raw and chemically modified cellulose isolated from sugarcane bagasse for decontamination of Cr(VI) wastewater. First, pulp by subjecting it to acid hydrolysis, alkaline hydrolysis bleaching with sodium chlorate (NaClO
This study investigates the wild plant species for their phytoremediation potential of macro and trace metals (MTM). For this purpose, soil samples were collected along mafic ultramafic terrain in Jijal, Dubair, Alpuri areas Kohistan region, northern Pakistan. These analyzed concentrations MTM (Na, K, Ca, Mg, Fe, Mn, Pb, Zn, Cd, Cu, Cr, Ni, Co) using atomic absorption spectrometer (AAS-PEA-700). Soil showed significant (P < .001) contamination level, while plants had greater variability...
Abstract BACKGROUND The bioremediation versatility of soil indigenous microbial community for the degradation oil contaminated soils has been evidenced previously. In this study, three dominant bacterial strains, Pseudomonas putida (P. putida) and two aeruginosa ) (accession numbers ATCC‐27853, BAA‐427, ATCC‐49128), were isolated from different oil‐contaminated sites to evaluate their potential. Degradation potential was determined against compounds, naphthalene pyrene, polycyclic aromatic...
Particulate matter (PM) is a major air pollutant causing serious health problems. The aim of the present study was to find out concentration PM in ambient and its associated risk Haripur city, Pakistan. Twenty-three samples were taken at various educational institutes, hospitals, recreational areas industries city. Concentration PM2.5 (µg/m3) PM10 measured with Youngteng YT-HPC 3000A portable counter. results revealed that values both above permissible limits (35 µg/m3 for 150 PM10) set by...
We aimed to find the toxicological impacts of Cd, Pb and Zn in single dozes combinations on Purslane (Portulaca oleracea) seedling. The Pursolane seedlings grown pots a green house were treated with different soil treatments spiked (mg/kg) (300, 400 500), Cd (0.5, 1 1.5), (250, 500, 700) alone then specified combinations/concentrations i.e., Cd/Pb (0.5/300, 1/400, 1.5/500), Cd/Zn (0.5/250, 1/500, 1.5/700) Pb/Zn (300/250, 400/500, 500/ 700). results indicated that increasing concentrations...
A study was carried out with maize as the test crop to investigate bioavailability and leachability of heavy metals (HM) from HM-contaminated soils treated composted manure. The application manure increased shoot growth by 32.3% root 30.5% compared fresh concentration HM in varied order lead (Pb) > nickel (Ni) zinc (Zn) chromium (Cr) copper (Cu) cadmium (Cd). Whether for or root, metal concentrations decreased length composting increased, but were higher than shoot. Composting and, hence,...
Salmonella enterica serovar Typhi is Gram negative, rod shaped, facultative anaerobic bacterium, belongs to enterobacteriaceae family that causes typhoid fever in humans. This bacterium has become a super bug due acquisition of multi drug resistance. Bacteria transmitted through food and water contaminated with human feaces. Present study reports the screening Adhatoda vasica, Amaranthus hybridus Aloe barbadensis their evaluation against multi-drug resistant Typhi. Qualitative analysis ten...
Water contamination with potentially toxic elements (PTEs) has become one of the key issues in recent years that threatens human health and ecological systems. The present study is aimed at removing PTEs like cadmium (Cd), chromium (Cr), copper (Cu) lead (Pb) from aqueous solutions industrial wastewater using activated carbon (AC) as an adsorbent through different batch column experiments. Results demonstrated removal was highly pH dependent, except for Cr, maximum (>78%) recorded 6.0....
The adsorptive removal of lead (II) from aqueous medium was carried out by chemically modified silica monolith particles. Porous particles were prepared the sol-gel method and their surface modification using trimethoxy silyl propyl urea (TSPU) to prepare inorganic-organic hybrid adsorbent. resultant adsorbent evaluated for (Pb) medium. effect pH, dose, metal ion concentration adsorption time determined. It found that optimum conditions pH 5, dose 0.4 g/L, Pb(II) ions 500 mg/L 1 h. SM...
Abstract Heavy metals determination in manures provides beneficial information to predict the availability and potential contamination of environment. Therefore, a study was carried out investigate heavy changes livestock manure during co-composting process. The were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate precipitated residual forms by extracting with 0.5M KNO 3 , de-ionized water, NaOH, 0.05M Na 2 EDTA 4M HNO respectively. During extraction process,...
This study was conducted to investigate heavy metal contamination and potential health risk of ground water selected municipal solid waste (MSW) disposal sites Khyber Pakhtunkhwa (KP) Pakistan. For this purpose a total 30 composite samples both surface were collected from dumpsites Abbottabad, Bannu Peshawar. The analyzed for physico-chemical parameters metals by following standard methods. Results indicated that pH values found within the acceptable limits specified national environmental...
Phosphorus (P) is considered one of the most important nutrients for plant growth.It used as a fertilizer either commercially available or in form manure, and also plays key role growth livestock.Animal manure sources P. The concentration P varies with age livestock, diet, bedding type.It depends on livestock species.P found animal exists organic inorganic form.In general, 45-90% nature other supposed to be [1].Composted richer than fresh [2].However, fresh, non-composted has higher nitrogen...
