E-waste environmental contamination and harm to public health in China

Xijin Xu,Xiang Zeng,H. Marike Boezen,Xia Huo

Frontiers of Medicine 2015, Volume 9, Issue 2,   Pages 220-228 doi: 10.1007/s11684-015-0391-1

Abstract:

The adverse effects of electronic waste (e-waste) on the human body have stirred up concern in recent years. China is one of the countries that confront serious pollution and human exposure of e-waste, and the majority of the population is exposed to potentially hazardous substances that are derived from informal e-waste recycling processes. This study reviews recent reports on human exposure to e-waste in China, with particular focus on exposure routes (e.g., inhalation and ingestion) and several toxicities of human (e.g., endocrine system, respiratory system, reproductive system, developmental toxicity, neurotoxicity, and genetic toxicity). Pieces of evidence that associate e-waste exposure with human health effects in China are assessed. The role of toxic heavy metals (e.g., lead, cadmium, chromium, mercury, and nickel) and organic pollutants (e.g., polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyl (PCBs), polycyclic aromatic hydrocarbons (PAHs), polybrominated biphenyls (PBBs), polyhalogenated aromatic hydrocarbons (PHAHs), bisphenol A (BPA)) on human health is also briefly discussed.

Effective remediation of organic-metal co-contaminated soil by enhanced electrokinetic-bioremediation process

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 6, doi: 10.1007/s11783-021-1401-y

Abstract: Abstract • A new EK-BIO technology was developed to decontaminate e-waste contaminated soil. • Adding sodium citrate in electrolyte was a good choice for decontaminating the soil. • The system has good performance with low cost. This work investigates the influence of electrokinetic-bioremediation (EK-BIO) on remediating soil polluted by persistent organic pollutants (POPs) and heavy metals (mainly Cu, Pb and Ni), originated from electronic waste recycling activity. The results demonstrate that most of POPs and metals were removed from the soil. More than 60% of metals and 90% of POPs in the soil were removed after a 30-day EK-BIO remediation assisted by citrate. A citrate sodium concentration of 0.02 g/L was deemed to be suitable because higher citrate did not significantly improve treatment performance whereas increasing dosage consumption. Citrate increased soil electrical current and electroosmotic flow. After remediation, metal residues mainly existed in stable and low-toxic states, which could effectively lower the potential hazard of toxic metals to the surrounding environment and organisms. EK-BIO treatment influenced soil microbial counts, dehydrogenase activity and community structure.

Remediation of soil heavily polluted with polychlorinated biphenyls using a low-temperature plasma technique

Xiuhua LI, Haibo ZHANG, Yongming LUO, Ying TENG

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 2,   Pages 277-283 doi: 10.1007/s11783-013-0562-8

Abstract: Polychlorinated biphenyls PCBs) were removed by low-temperature plasma technique (dielectric barrier discharge) from heavily polluted soil and their intermediate products were analyzed. The removal rate ranged from 40.1 to 84.6% by different treatments, and they were also influenced significantly ( <0.01) by soil particle-size, electric power, gas flow rate and reaction time. The optimal reaction conditions of PCB removal from the soil were obtained experimentally when soil particle-size, electrical power, flow rate and reaction time were 5–10 mm, 21 w, 120 mL· min and 90 min, respectively. However, decreasing electrical power, flow rate and reaction time to 18 w, 60 mL· min and 60 min respectively were also acceptable in view of the cost of remediation. This technique was characterized by the additional advantage of thorough oxidation of PCBs in the soil, with no formation of intermediate products after reaction. The technique therefore shows some promise for application in the remediation of soils contaminated with persistent organic pollutants in brown field sites in urban areas.
