“…Furthermore, mining processing of earth metals that is carried during the manufacturing of electronic devices and its waste generation are additional contributors to the CO 2 footprint [27]. Mining and processing of raw resources do not only contribute to global warming but also produce huge amounts of waste that impact environmental and human health [28]. Overall, acid mine drainage, metal deposition, sedimentation, the impact on biodiversity, and waste generation are the main categories of environmental effects of mining and mineral processing for the electronics industry [26].…”

Electronic waste (e-waste) is the fastest-growing class of waste because of the remarkable demand for various electronic gadgets such as mobiles and laptops. Moreover, its improper disposal is life-threatening because it includes hundreds of different substances, many of which are toxic elements and pollutants that can leach to soil and surface and groundwater or be emitted into the air, causing a major negative impact on the environment and public health. As a result, studies on the sustainable management of e-waste have gained increasing attention from researchers globally in the last decade to explore practical strategies to reduce or utilize this special waste. This review aims to provide an in-depth understanding of the major aspects of e-waste, including its definition, composition, and the impact of its end-of-life disposal on human health and the environment, while also focusing on some practical sustainable solutions and strategies toward effective e-waste management. It will also discuss the production of electronics; global demand and the mining boom; and the pollution caused by mining. It will also highlight the importance of effective governmental regulations, with which electronics producers, e-waste generators, and recycling facilities should comply. The research perspectives and orientations highlighted within this review can help in providing guidelines for future research studies and in exploring opportunities for more effective management of e-waste toward a circular economy and sustainable development.

“…Consumption of metal-rich fish is of concern because chronic exposure to metals can cause health problems. Metals are transported to fish via the bloodstream, and ions are usually bound to proteins [5,6]. The metal comes into contact with the fish's organs and tissues and as a result, it molds into different fish organs and tissues to varying degrees.…”

A serious problem that arose with the evolution of modern industry is generation of electrical and electronic equipment waste. In the last decades, the generation of electronic waste has increased a lot and it is estimated that in 2030, almost 74 tons of electronic waste will be generated, which will represent a significant threat to the environment. The purpose of this article is to track the potential impacts on the environment, to highlight the importance of waste management strategies and to provide the latest information in the field. A presentation of the countermeasures that must be taken at the national and international level to address the sensitive problem of waste management is also realized.

“…Future biomonitoring and epidemiological studies are critically needed to assess such health parameters in residents and workers at the e-waste dumpsite examined in this study. In a report by Sweta [47], regular aquatic risk assessment was recommended for water bodies in close proximity to e-waste processing plants to evaluate and identify potential risks posed by exposure to e-waste contaminants. Moreover, goals should be set to achieve a comprehensive and successful e-waste management program that encompasses all stakeholders, including unskilled ewaste recyclers, recycling companies, traders, general public, and regulatory authorities, for which risk communication skills are a must [48].…”

The Chemistry and Health Outcomes of Electronic Waste (E-Waste) Leachate: Exposure to E-Waste Is Toxic to Atlantic Killifish (Fundulus heteroclitus) Embryos

Although there is rising global concern over the environmental, ecological, and human health risks associated with the discharge of leachates from e-waste dumpsites into the aquatic ecosystems, little is known in this research area. Thus, for this study, we first defined the chemistry of the test leachate, followed by assessment of the leachate on the development of a model aquatic organism (Fundulus heteroclitus) used extensively as a bioassay organism in pollution studies. Chemical analyses revealed that levels of phosphate (20.03 mg/L), cadmium (Cd) (0.4 mg/L), lead (Pb) (0.2 mg/L), and chromium (Cr) (0.4 mg/L) were higher than the 2009 US EPA and the 2009 National Environmental Standards and Regulations Enforcement Agency (NESREA) permissible limits. Polycyclic aromatic hydrocarbon (PAH) burdens were dominated mainly by the high molecular weight congeners, specifically the ∑4rings (73 µg/L). Total polychlorinated biphenyls (PCB) levels ranged from 0.00 to 0.40 µg/L with the ∑deca PCBs reaching the highest concentration. For the biological studies, F. heteroclitus embryos (48-h post-fertilization) were divided randomly into groups and exposed to one of six e-waste leachate concentrations (10, 1, 0.1, 0.01, 0.001, 0.0001%). Significant differences (p ≤ 0.05) between treated and control groups were observed in standard and total length, and head size. Further analysis using Duncan’s post-hoc test of multiple comparison also revealed specific differences within and between specific treatment groups. We conclude that e-waste leachate arising from indiscriminate dumping into aquatic ecosystems in Nigeria contains mixtures of toxic constituents that can threaten ecosystem and public health.
