Information and telecommunications technology (ICT) computer Internet networking has penetrated nearly every aspect of modern life, is positively affecting human life even in the most remote areas developing countries. The rapid growth ICT led to an improvement capacity computers but simultaneously a decrease products lifetime as result which increasingly large quantities waste electrical electronic equipment (e-waste) are generated annually. development countries, particularly Africa,...

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...

This baseline study investigated the physico-chemical and trace elements (including potentially toxic elements, PTEs) contents of ground surface water sources used for domestic purposes in some districts within shale bedrock terrain Southeastern Nigeria. A total 124 samples from 13 natural springs, 24 streams, 80 boreholes 7 hand-dug wells were collected rural urban areas analysed by ICP-OES, GF-AAS CV-AFS 21 elements. The distribution pattern, contamination, health risk (PTEs), together...

Mining/exploitation and commercial applications of the rare-earth elements (REEs: La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) in past 3 decades have raised concerns about their emissions to environment, possible accumulation food webs, occupational/environmental health effects. The occurrence distribution REEs Y Sc fruitbodies

This study investigates the trace metal contents of three wide-grown Nigerian edible mushrooms and their bioaccumulation potentials. Samples mushroom fruiting body (n = 45) Pleurotus tuberregium, Auricularia auricular Lentinus squarrosulus wooden substrates 45), respectively, were collected from forest regions in south-eastern Nigeria. The concentrations Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni Pb using flame AAS after mineralization acid. varied 6.23 to 47.63 for Mg; 2.59 771 Ca; 1.27...

The rapid improvements in the electronics industry, electronic waste (E.waste), including all obsolete products, has becoming fastest growing component solid stream.This phenomenon been a source of hazardous wastes such as personal computers (PCs) and Televisions (TVs), which contain heavy metals organic compounds that pose risk to environment sustainable economic growth.Informal E.waste recycling practices Nigeria open burning recover metals, dumped or stockpiled resulted due lack national...

Abstract BACKGROUND: This paper reports data on bioconcentration potential and baseline mercury concentrations of fruiting bodies dark honey fungus ( Armillaria solidipes ) Peck soil substrate layer (0–10 cm) from 12 spatially distant sites across Poland. Mercury content caps, stipes samples were determined using validated analytical procedure including cold‐vapor atomic absorption spectroscopy after thermal decomposition the sample matrix further amalgamation desorption gold wool. RESULTS:...

Presented in this paper is result of the study bioconcentration potential mercury (Hg) by Suillus luteus mushroom collected from regions within Central, Eastern, and Northern Europe. As determined cold-vapor atomic absorption spectroscopy, Hg content varied 0.13 ± 0.05 to 0.33 mg kg(-1) dry matter for caps 0.038 0.014 0.095 stems. The soil substratum (0-10 cm layer) underneath fruiting bodies showed generally low concentrations that widely ranging 0.0030 0.15 with mean values varying 0.0078...

This paper reports the results of study Hg contents four species Boletus mushroom (Boletus reticulatus Schaeff. 1763, B. pinophilus Pilát & Dermek 1973, impolitus Fr. 1838 and luridus 1774) surface soils (0–10 cm layer, ∼100 g) samples beneath mushrooms from ten forested areas in Poland Belarus by cold-vapour atomic absorption spectroscopy. The ability to bioconcentrate was calculated (as BCF) while intakes consumption these were also estimated. median content caps varied between 0.38 4.7 mg...

Nowadays, desalination has become a very affordable solution to cope with fresh water shortage typically in tropical as well off-shore areas.The core process is based on Reverse Osmosis membrane technology.Reverse (RO) method of obtaining pure from containing salt, [1].It purification technology that uses semi permeable remove ions, molecules and larger particles drinking water.In reverse osmosis, an applied pressure used overcome osmotic pressure, colligative property driven by chemical...

This paper reports the results of study efficiency accumulation and distribution mercury (Hg) in fruiting bodies fungus Suillus bovinus probable dietary intake Hg potential health risk. Fungal soil materials were collected from 13 background areas northern part Poland between 1993 2013. Mercury caps varied 0.10 ± 0.06 to 0.79 0.40 mg kg−1 dry biomass stipes 0.083 0.028 0.51 0.22 biomass. The mean values cap stipe content quotient 1.3 0.2 2.6 0.6. upper 0–10 cm layer substrate 0.015 0.004...
