The feasibility of producing activated carbon (AC) from real Household Mixed Plastic Waste (HMPW) comprising LDPE, HDPE, PP, PS, and PET for capture via direct carbonisation followed by microwave-assisted or conventional thermally assisted chemical activation was investigated. A procedure adopted to assess the impact on CO2 capacity resulting AC using both a lower temperature (400 °C vs. 700 °C) shorter duration (5 120 mins) than that required activation. results obtained showed yield 71 78%...

The slaughtering of animals and processing meats for human consumption generates enormous wastes which are not properly managed in most developing nations including Nigeria. Majority people Akwa Ibom state southern Nigeria depend on meat as their major source protein, abattoir applied farms organic manure by some farmers. This study examined the role abattoir-related waste products physicochemical properties, total metal, metal speciation soil. data obtained were also subjected to treatments...

Microwave (MW) heating is proposed as a method to transform polyethylene terephthalate (PET) into porous adsorbents. The yield, textural properties, and CO2 uptake of the PET-derived adsorbents irradiated at different durations (3 – 35 min) 400 °C were assessed. MW activation time influenced both physical properties capacities resulting yield decreased with time, but surface area, total pore volume, micropore all increased before declining. optimal sample (produced 5 min time) showed...

Vegetable oils obtained from different oil plants are mainly used as a source of food and in the production cosmetics, lubricants, paints, pharmaceuticals, biodiesel, among others. Nowadays, plant –based contain variety phytochemicals largely preferred to animal fat because its low or complete absence cholesterol, presence unsaturated free fatty acids, complex carbohydrates fat-soluble vitamins like A, D, E, K. This study aimed determine physicochemical properties Dialiumguineense (African...

Total concentration, speciation, sources and potential health problems of Pb, Cd, Cu, Fe Ni in a dumpsite soil within Calabar Municipality were evaluated this work. The influence organic matter pH the studied on metal availability was also assessed. Results obtained indicated that; mean concentration all metals higher than Control their recommended limits for Nigerian as well. Metal speciation revealed that, Pb existed mainly reducible form; Cd occurred acid extractable fraction, Cu...

This research assessed the level, source and associated health risks of trace metals in waste-impacted soils within Nigeria. Results reported revealed that mean concentrations for all studied were higher than their levels control. The except Ni also recommended limits Nigerian soil by Federal Environmental Protection Agency. Pollution assessment these different locations indicated Pb Cd with very high contamination status. obtained Fe mainly from natural geological processes while Pb, Cu...

The intensive application of manures for the improvement plant yield is a global practice by farmers notwithstanding associated negative effects. probability health risk, bioaccumulation, and speciation arsenic (As), cadmium (Cd), nickel (Ni), lead (Pb) in soils vegetables (Talinum triangulare Telfairia occidentalis) impacted untreated wastes from animal farms inorganic fertilizers used as oil producing section Nigeria were investigated. total metal was determined using spectrophotometric...

Health risks of toxic metals and polycyclic aromatic hydrocarbons (PAHs) associated with the consumption Telfairia occidentalis Talinum triangulare impacted by wastewater from water treatment plants within Uyo Metropolis, Southern Nigeria, were investigated using standard methods. The level PAHs was higher in vegetables food processing industries than other sources. levels cadmium (Cd), lead (Pb), arsenic (As), chromium (Cr) exceeded their recommended limits Food Agriculture Organization...

The impact of indiscriminate disposal waste materials on the quality Aba River was examined in this research. Levels Cd, Pb, Cu, Ni, Fe, Zn, Cr, and Mn were determined water sediments from River. Modified BCR sequential extraction procedure employed for fractionation metals sediments. toxic (Cd, Cr) higher than their recommended limits potable water. However, mean levels all except Fe within safe sediment. also significantly at p < 0.05. Results showed that Cr existed mostly non-residual...

Influence of abattoir wastes on physicochemical and microbiological properties soil samples obtained from Akwa Ibom State, Southern Nigeria were investigated using standard analytical methods. Studied abattoirs the control soils in sandy-clay-loamy category with varied quantities sand, silt clay. Bulk density, pH , electrical conductivities, salinity, moisture content, total organic carbon cation exchange capacities, petroleum hydrocarbon, nitrogen phosphorus contents studied higher than...

A number of local butchers in Uyo metropolis usually make use used scrap car tyres (USCT) and condemned plastics (CPS) as close substitutes for firewood to singe slaughtered ruminants. This study evaluated the effect singeing materials on distribution some metals (Cd, Cr, Ni, Pb, Cu, Zn Fe) liver kidney samples Capra aegagrus hircus (goat) Village Road Abattoir Niger Delta Region Nigeria using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). Carcinogenic non-carcinogenic...

Sludge samples were collected from a wastewater treatment plant in Nigeria for characterization and evaluation agricultural applications. Conventional Molecular techniques adopted the isolation identification of indigenous microorganisms resulting isolates characterized identified by consulting Bergey’s manual determinative bacteriology subjected to further screenings assess their biofertilizer potential using standard microbiological techniques. The viable cells obtained enumerated found be...

Four common biochemical constituents of some vegetable leaves sourced from abattoir waste – impacted soils and a Control within Uyo Metropolis in Niger Delta Region Nigeria were assessed for their air pollution tolerance capacities using standard analytical protocols. Results indicated varied amounts studied with respect to the different showing direct relationship another. Biochemical analyzed higher soil than except relative water content. Tolerance levels based on Thakar’s Padmavathi’s...
