“…This is a costly method and may not be suitable for applications in large areas. Dellisanti et al [185] carried out the vitrification of Pb-rich ceramic waste. Wang et al [186] treated fly ash from a municipal solid waste incinerator to radiated heavy metals including Pb.…”

Lead (Pb) toxicity has been a subject of interest for environmental scientists due to its toxic effect on plants, animals, and humans. An increase in several Pb related industrial activities and use of Pb containing products such as agrochemicals, oil and paint, mining, etc. can lead to Pb contamination in the environment and thereby, can enter the food chain. Being one of the most toxic heavy metals, Pb ingestion via the food chain has proven to be a potential health hazard for plants and humans. The current review aims to summarize the research updates on Pb toxicity and its effects on plants, soil, and human health. Relevant literature from the past 20 years encompassing comprehensive details on Pb toxicity has been considered with key issues such as i) Pb bioavailability in soil, ii) Pb biomagnification, and iii) Pb- remediation, which has been addressed in detail through physical, chemical, and biological lenses. In the review, among different Pb-remediation approaches, we have highlighted certain advanced approaches such as microbial assisted phytoremediation which could possibly minimize the Pb load from the resources in a sustainable manner and would be a viable option to ensure a safe food production system.

“…However, dry soil may not provide enough conductance for vitrification. Recently, Dellisanti (2016) carried out an in-field Joule heating vitrification of tons of Zn and Pb rich ceramic waste by heating up to about 1850°C. They reported that the vitrification method was greatly efficient to clean-up tons of heavy metal(loid)s contaminated waste materials and can be applied for cleaning huge volumes of soil.…”

, et al.. A comparison of technologies for remediation of heavy metal contaminated soils. Journal of Geochemical Exploration, Elsevier, 2016Elsevier, , 182, pp.247 -268. 10.1016Elsevier, /j.gexplo.2016 Any correspondence concerning this service should be sent to the repository administrator: staff-oatao@listes-diff.inp-toulouse.fr a b s t r a c tSoil contamination with persistent and potentially (eco)toxic heavy metal(loid)s is ubiquitous around the globe. Concentration of these heavy metal(loid)s in soil has increased drastically over the last three decades, thus posing risk to the environment and human health. Some technologies have long been in use to remediate the hazardous heavy metal(loid)s. Conventional remediation methods for heavy metal(loid)s are generally based on physical, chemical and biological approaches, which may be used in combination with one another to clean-up heavy metal(loid) contaminated soils to an acceptable and safe level. This review summarizes the soil contamination by heavy metal(loid)s at a global scale, accumulation of heavy metal(loid)s in vegetables to toxic levels and their regulatory guidelines in soil. In this review, we also elucidate and compare the pool of available technologies that are currently being applied for remediation of heavy metal(loid) contaminated soils, as well as the economic aspect of soil remediation for different techniques. This review article includes an assessment of the contemporary status of technology deployment and recommendations for future remediation research. Finally, the molecular and genetic basis of heavy metal(loid) (hyper)accumulation and tolerance in microbes and plants is also discussed. It is proposed that for effective and economic remediation of soil, a better understanding of remediation procedures and the various options available at the different stages of remediation is highly necessary.

“…The graphite tube provides a relatively inexpensive cross-section that accelerates the conduction of current into the melt, and also provides a protective layer for the molybdenum inner electrode. When the process is finished, the graphite tube is sacrificed because it is left in the melt, while the more expensive inner electrode can be reused, which provides cost savings [21,22,59,65].…”

Various types of contaminated soil and hazardous waste that have a negative impact on the environment and human health can be treated with the vitrification process. This process is based on thermal treatment of contaminated soil or waste at high temperatures, with the addition of additives, whereby the soil/waste melts and a stable glass is formed. The resulting glass and glass-ceramic products have good mechanical resistance, chemically are resistant and immobilize contaminants, thus preventing their further negative impact on the environment. This paper presents a literature review of the vitrification process of different types of contaminated soil and hazardous waste.
