Barnes and Dourson (1988) described EPAs approach and rationale to assessing noncarcinogenic health risks from chronic chemical exposure. EPA approach follows the general format as set forth by the NRC (NRC 1983). The conceptual difference between safety and uncertainty is discussed within the context of the terms SF versus UF and ADI versus RfD. The authors state that SF suggests the notion of absolute safety and that the ADI is generally and erroneously interpreted as a strict demarcation between what is acceptable and what is safe in terms of chronic exposure. Rather, the ADI represents an estimate of a xenobiotic exposure or daily dose where the probability of adverse effects is low but a level where the complete absence of all risk to all people under all conditions of exposure cannot be assured. Consequently, the RfD and UF terminology was developed and adopted by EPA. EPA considers the RfD to be an estimate (with uncertainty spanning perhaps an order of magnitude of a daily exposure to a human population, including susceptible subpopulations) that is likely to be without an appreciable risk of deleterious effects during a lifetime

The distribution of intracellular zinc, predominantly regulated through zinc transporters and zinc binding proteins, is required to support an efficient immune response. Epigenetic mechanisms such as DNA methylation are involved in the expression of these genes. In demethylation experiments using 5-Aza-2'-deoxycytidine (AZA) increased intracellular (after 24 and 48h) and total cellular zinc levels (after 48h) were observed in the myeloid cell line HL-60. To uncover the mechanisms that cause the disturbed zinc homeostasis after DNA demethylation, the expression of human zinc transporters and zinc binding proteins were investigated. Real time PCR analyses of 14 ZIP (solute-linked carrier (SLC) SLC39A; Zrt/IRT-like protein), and 9 ZnT (SLC30A) zinc transporters revealed significantly enhanced mRNA expression of the zinc importer ZIP1 after AZA treatment. Because ZIP1 protein was also enhanced after AZA treatment, ZIP1 up-regulation might be the mediator of enhanced intracellular zinc levels. The mRNA expression of ZIP14 was decreased, whereas zinc exporter ZnT3 mRNA was also significantly increased; which might be a cellular reaction to compensate elevated zinc levels. An enhanced but not significant chromatin accessibility of ZIP1 promoter region I was detected by chromatin accessibility by real-time PCR (CHART) assays after demethylation. Additionally, DNA demethylation resulted in increased mRNA accumulation of zinc binding proteins metallothionein (MT) and S100A8/S100A9 after 48h. MT mRNA was significantly enhanced after 24h of AZA treatment also suggesting a reaction of the cell to restore zinc homeostasis. These data indicate that DNA methylation is an important epigenetic mechanism affecting zinc binding proteins and transporters, and, therefore, regulating zinc homeostasis in myeloid cells.

In recent years, the technique of alkaline cyanide dissolution has been highly developed. It is especially suitable for processing low-grade gold and silver ore (e.g. less than 5 ppm gold), but its use is not limited to such ores. This extraction method involves many environmental hazards, largely due to the high acute toxicity of the involved cyanide compounds

The efficient use of coke and anthracite in producing iron was accelerated by the use of steam-driven equipment, the invention of equipment to preheat air entering the blast furnace and the design of the tuyeres and the tuyere composition (Wakelin, 1999). The evolution of both coke and anthracite ironmaking paralleled each other in the United States during the 1800s, and by 1856 there were 121 anthracite furnaces in operation. With coke being the strongest and most available fuel, the evolution of 100% coke furnaces continued with major steps being made in the Pittsburgh, Pennsylvania area between 1872 and 1913. The Carnegie Steel Company and its predecessor firms developed technological process improvements at its Monongahela Valley ironmaking furnaces that ultimately made it possible for the United States to take over worldwide leadership in iron production. This is not true today, however, as much of the steel production has shifted overseas beginning in the 1960s and early 1970s
