Effluents from five major textile industries in Kaduna (Nigeria) were characterized for a proposed central effluent treatment plant. Seven of the measured parameters exceeded limit set by Federal Ministry Environment. Colour intensity it all samples (Mills 1 – 5) about 350 folds on average while COD, TSS, NH3, BOD5, and S2- 24, 13, 8, 7 3 respectively. TDS was detected with only Mill 2. Nitrate, oil grease Mills 2 within limit. Al, Mn, Zn 80% Fe 60 %. Cu 80 % average. The present study is...

The increasing rate of unregulated emissions particulate matters from different sources in Nigeria is great concern. This study therefore focused on monitoring (PM2.5 and PM10) level some municipal areas Nigeria. also simulated the dispersion pattern assessed health risk matter exposure. PM2.5 PM10 selected were quantified for 8 months using Centre Atmospheric Research (CAR) satellite-based sensors. Hybrid single-particle Lagrangian integrated trajectory (HYSPLIT) model was used to simulate...

This study estimates the contribution from open burning of municipal wastes in some Nigeria's major cities to atmospheric levels air pollutants. Information obtained on emission factors and solid waste (MSW) generation was combined estimate annual pollutants MSW. Per capita distributions were calculated basis cities' populations. The inorganic emissions across studied 913.73 81,600 tons per year (TPY) particulate matter; 4,797 428,400 TPY oxides nitrogen; 342.65 30,600; 57 5,100 sulfur...

Adsorbents from chicken eggshells were synthesized by a simple method and used as novel effective adsorbent for the removal of carbon monoxide (CO) an ambient environment. The adsorbents characterized X-ray fluorescence (XRF), Atomic absorption spectroscopy (AAS), Fourier transform infrared (FTIR), Proximate, ultimate analysis adsorption isotherms. characterization results showed that presence Ca, CaO, SiO2, CO, O-H, O-Si-O stretching vibration bonding contributed to capacity adsorbents....

The data in this article were obtained from a research designed to investigate the effects of choice solvent, mixing speed, temperature and solvent oil ratio on treatment process used lubricating oils using extraction adsorption method. Various performance three solvents chosen studied compared based certain parameters are presented discussed. From results obtained, it was observed that MEK (Methyl Ethyl Ketone) had best because gave highest sludge removal closest properties fresh base...

The increase in price of the available refined petroleum products for local consumption Nigeria had led to emergence indigenous technology refining some parts Niger Delta region. This study, therefore characterized and quantified artisanal refineries' gaseous emissions possible air pollutants based on various unit operations involved evaluated their impacts. It measured directly from source using E8500 Portable Combustion Analyzer. also categorized oven sizes/processing capacity refineries...

In this work level of Polycyclic Aromatic Hydrocarbon (PAHs) from indoor Environment Tobacco Smoke (ETS) pubic bars in Nigeria was investigated. Indoor air samples were obtained different public using Polyurethane foam (PUF) passive samplers. Analysis PAHs carried out GC-MS operated selected ion monitoring mode. Result showed the average concentration range 2.71–9.69 ng/m3 while ∑ 16 43.43 to 155.11 ng/m3. The incremental lifetime cancer risk (ILCR) values inhalation these ranged...

The study investigated the annual atmospheric loadings of particulate matter (PM) from open burning sawdust in southwestern Nigeria using emission factor approach. estimated loading PM states ranged between 1.18–8.29 ton/annum while 23.4 was obtained for entire Nigeria. maximum per capita and land distribution were to be 0.844 g/capita 304.592 g/km2 these Ondo Lagos States, respectively. dominant elemental emissions potassium sodium with 10.4 10.1 ton/annum, Heavy metals such as lead mercury...

High emission factor of identified air pollutants from the artisanal petroleum refineries in Niger Delta region may be key to degrading quality region. This study determined for local refining technology The operational sites these are inaccessible due security and proximity raw material, making evaluation management impossible. However, Emission Factors one best ways quantify an activity-related pollution especially difficult terrain like those refineries. In this regard, emissions...

Abstract The study identified sources and established the levels of industrial noise in Okomu National Park with aim determining impact pollution on wildlife Park. It also modelled propagation ambient associated as well determined impacts obtained from activities Locations including relative to were digital maps locations was generated. Ambient for populations around selected locations. Noise assignment done at each hotspots activity that had been detected using EXTEC sensors. average then...

Purpose The aim of this paper is to better understand the impact petroleum production facilities on ambient air quality host airshed. Design/methodology/approach Field measurements were taken daily for four consecutive months around in Niger Delta area, Nigeria, one world's important producing areas. Statistical analysis tool and analytical known as index (AQI) applied field data obtained. Findings mean measured concentrations both carbon monoxide (CO) nitrogen dioxide (NO 2 ) between...

This study examined the ambient levels of criteria air pollutants in indoor and outdoor environment a typical hospital facility. Ambient concentration was monitored at nine sampling locations using ToxiRAE gas monitors both rainy dry seasons. The results showed that overall 24-h concentrations for CO NH3 were 0.18 ± 0.19 0.11 0.13 ppm, respectively, season. During wet season, extrapolated ranged 0.09–1.09 ppm CO, 0.04 0.08 while NO NO2 had 0.03–0.21 0–0.06 respectively. result shows 0.44...

Abstract An assessment of potential biomass resources in Nigeria for the production methane and power generation is presented this paper. Nigeria, as an underdeveloped populous country, needs uninterrupted source energy. The country's energy problems have crippled large sectors economy. percentage people connected to national grid 40%. These 40% experience electricity supply failure on average 10–12 hours daily. Energy from municipal solid waste (MSW) effective MSW management strategy....
