Chromium stability in steel slags Verlag Stahleisen Chromium is an essential element in steelmaking industry. Steel slag inevitably contains some chromium and there is a risk of Cr emission from slag to the environment, however, in which form the emission of the element occurs and whether it is a hexavalent Cr is a concern. ToAssessment of Human Health and Ecological Risks Posed by The risk assessment found no significant hazards to human health as a result of the environmental appliions of steelindustry slag. However, sitespecific ecological risk assessment may be required for slag appliions in and around small water bodies with limited dilution volume, because high pH and aluminum were found to leach at levels

Risk Assessments developed during 1998 demonstrate that the three kinds of slag produced by two types of steel making processes pose essentially no threat to human health or the environment when used
3.5 Characteristics of steelmaking slags Global CCS The initial screening process allowed the risk assessment to focus on a limited set of slag constituents (chemicals of interest). In general, the levels of metals in steelmaking slag were lower than expected, and, similarly, leachability was found to be very low.nationalslag.orgindustry slag and for human and ecological health risk assessment of environmental appliions. Introduction Iron and steel slag is produced as the nonmetallic coproduct of iron and steel production. There are three types of steel industry slag, each named for the process from which it is produced: Blast Furnace (BF) iron slag, Basic Oxygen

Steelmaking slag specifically slag generated from EAFs, BOFs, and BFs during the iron/steel making process has many important and environmentally safe uses. In many appliions, due to its unique physical structure, slag outperforms the natural aggregate forPhysical and Chemical Characteristics of Blast Furnace Approximately 21 million tons of steel industry slag are produced each year in the United States, and many productive commercial uses of slag have been developed (e.g., road bed, fill material). However, because slag contains heavy metals at concentrations that are higher than in most soil, questions have been raised regarding the need to evaluate the potential human health and
