“…These findings and those of our study are also consistent with the lack of published clinical case reports of dermatitis from contact with steel slag. Based on these findings for BOF slag (Reis da Silva et al, 2007), the findings of our study evaluating EAF slag, and the previous environmental and occupational health risk assessment for steel slag (Proctor et al, 2002), dermal contact with steel slag does not pose a dermal hazard.…”

“…Notably, the results for EAF slag as reported in this study are also consistent with that of basic oxygen furnace (BOF) steel slags from Brazil. In Reis da Silva et al (2007), fine-ground BOF slag and crushed stones from Brazil were used to dose the skin of three New Zealand albino rabbits based on OECD 404 guidelines (Reis da Silva et al, 2007). No irritation and corrosion effects in rabbits were observed from dermal exposure, and it was concluded that BOF slags from Brazil do not need to be classified as corrosive or irritant (Reis da Silva et al, 2007).…”

Electric arc furnace (EAF) steel slag is alkaline (pH of ~11-12) and contains metals, most notably chromium and nickel, and thus has potential to cause dermal irritation and sensitization at sufficient dose. Dermal contact with EAF slag occurs in many occupational and environmental settings because it is used widely in construction and other industrial sectors for various applications including asphaltic paving, road bases, construction fill, and as feed for cement kilns construction. However, no published study has characterized the potential for dermal effects associated with EAF slag. To assess dermal irritation, corrosion and sensitizing potential of EAF slag, in vitro and in vivo dermal toxicity assays were conducted based on the Organisation for Economic Co-operation and Development (OECD) guidelines. In vitro dermal corrosion and irritation testing (OECD 431 and 439) of EAF slag was conducted using the reconstructed human epidermal (RHE) tissue model. In vivo dermal toxicity and delayed contact sensitization testing (OECD 404 and 406) were conducted in rabbits and guinea pigs, respectively. EAF slag was not corrosive and not irritating in any tests. The results of the delayed contact dermal sensitization test indicate that EAF slag is not a dermal sensitizer. These findings are supported by the observation that metals in EAF slag occur as oxides of low solubility with leachates that are well below toxicity characteristic leaching procedure (TCLP) limits. Based on these results and in accordance to the OECD guidelines, EAF slag is not considered a dermal sensitizer, corrosive or irritant.

“…In addition, the performance of slag in construction is rather encouraging. However, there is still consideration on long-term volume stability of the slag in construction and the risk to environment and human health (Ferreira et al 2016;Reis da Silva et al 2007). Work on improving the volume stability of iron-and steelmaking slag is greatly required in order to promote the application of slag-obtained sand in construction.…”

Along with iron and steel production, large amount of slag is generated. Proper management on the iron-and steelmaking slag is highly demanded due to the high cost of direct disposal of the slag to landfill, which is the most adopted management approach. In this article, the potential application of iron-and steelmaking slag has been reviewed, which included the slag utilization in construction as cement and sand, in water, soil, and gas treatment, as well as in value material recovery. In addition, the challenge and required effort to be made in iron-and steelmaking slag management have been discussed.
