Abstract Background Currently, plastic is at the top of international agenda for waste management. Recent meetings Conferences Parties to Basel and Stockholm Conventions have expressed concerns over impact waste, marine litter, microplastics, emphasised importance reducing consumption ensuring environmentally sound management plastics. This study presents first continental historical analysis mass importation different polymers plastics (primary secondary forms, respectively) in Africa...

The quantity and generation rate of solid wastes in Nigeria have increased at an alarming over the years with lack efficient modern technology for management wastes. rate, collection disposal are functions several factors which if well considered appropriated could bring desired solution to waste problems Nigeria. cities Nigeria, influencing generation, types categories, collection, disposal, reuse recycling, environmental were investigated this study. results indicated large high without a...

Pollution has taken on a global dimension, and the effects are most obvious in developing countries. The take toll human health, animals, vegetation, as well soil, air, water quality. objective of this article is to discuss current relationships among pollution, environmental quality, health within frame anthropogenic activities In addition personal observations, we review relevant literature conditions throughout world case studies Nigeria. Key findings show significant, adverse...

Background.Plastic is a waste stream with recycling and recovery potential. However, the rates for plastic in African countries are low. Furthermore, use production of virgin plastics increasing. Therefore, high proportion being disposed landfills dumpsites. Plastic serves as fuel open burning at landfills/dumpsites associated releases constitutes large fraction marine litter, making it major growing global pollution concern.Objectives.This study aims to develop an initial inventory Nigeria...

Solid waste is of serious concern in developing countries because its high rate generation and the low-end quality management. Inefficient handling solid wastes may result deterioration environmental quality, but it can also loss potential resources. This study reviews current management Nigeria need for an effective collection, recovery, recycling policy. Our review based on literature searches personal field surveys. Observations showed that uncontrolled electronic (e-waste),...

Contamination of rivers with persistent organic pollutants (POPs) is an issue current global concern. Polychlorinated biphenyls (PCBs) are POPs origin from commercial, incineration and industrial sources. Hence, there a need for monitoring their occurrence distribution in the environment. This study assessed occurrence, composition profiles PCBs River Niger, Nigeria. Surface bottom water samples were collected consecutive quarters period 2 years, covering beginning end rainy seasons dry...

Potash alkali and metal contents of ashes obtained from peels six varieties Nigeria Musa species were investigated. The – paradisiaca (plantain), ‘Gross Michel’ (Igbo banana), M.sapientum L. (paranta), ‘Wild Banana’ (omini), ‘Red’ (sweet ‘Fugamo’ (somupeke), moisture, dry matter, ash contents; concentration metals in the extracted with water ashes; ratio potassium to other corresponding extracts determined. Moisture ranged 80.9 86.7%; matter content, 13.3 19.1%; 6.3 12.0%; 69.0 81.9% 4.7...

Short-chain and medium-chain chlorinated paraffins (SCCPs/MCCPs) are of concern due to their persistence, bioaccumulation, toxicity. SCCPs were listed in 2017 as persistent organic pollutants (POPs) the Stockholm Convention Rotterdam for Prior Informed Consent (PIC) procedure. MCCPs evaluated POPs Reviewing Committee listing. Studies Africa demonstrate high SCCP/MCCP levels house dust human milk. Therefore, this study undertook an initial assessment production import situation Nigeria. The...

Anthropogenic polychlorinated biphenyls (PCBs) in aquatic environments poses human and ecological health risks Nigeria.This study determined the concentrations of PCBs brackish water fish River Niger to assess contamination status consumed by local population.The sampled species included Drepane africana, Mochokus niloticus, Chrysichthys nigrodigitatus, Pristipoma jubelini, Vomer septapinis, Pseudotolithus senegalensis, Mugil cephalus, elongatus, Sphyraena piscatorum Lutjanus goreensis,...

Investigation of the levels organochlorine pesticides (OCPs) in fish samples was carried out to assess contamination status Niger River. Ten different brackish water species (6 for each, making a total 60) were purchased from landing sites at Delta area These Drapane africana, Mochokus niloticus, Chrysichthys nigrodigitatus, Pristipoma jubelini, Vomer septapinis, Pseudotolithus senegalensis, Mugil cephalus, elongatus, Sphyraena piscatorum , and Lutjanus goreensis . OCPs determined using...

Pollution in aquatic ecosystems is a serious environmental concern. There great need for constant assessment and monitoring of hazardous substances, particularly environments developing countries, as rivers are media with easy trans-boundary transport chemical substances.The present study assessed the occurrence distribution organochlorine pesticides (OCPs) sediments Niger River, Nigeria.A total 120 samples sediment were collected from 15 locations along river using Van Veen grab. The...

This study assessed combustion and potash production as options for management of wood waste. The percentage reduction in volume by generation potential waste from ninedifferent common species obtained a factory Ibadan were evaluated. Potash the ashes was extracted with distilled water through system filtration. amount ash, kilogram per cubic metre saw dust, potash, ash dust determined. sawdust reduced 95% after combustion. generated ranged between 1.42 – 15.18 Kg/m3; yield 4.74 53.76 Kg/m3...
