“…This phenomenon of transformation of nonrepairable Cd-induced lesions into repairable ones was shown in the experiments with pretreatment of cells by some antimutagens, in particular garlic extract, which was described in the corresponding section of this review. Similar data were obtained for chrome compounds [74]. In workers occupationally exposed to these compounds, resistance to γ-radiation in vitro (i.e., AR) developed.…”

Systems ensuring protection of human cells against endogenous and exogenous mutagenic factors are considered in terms of genetic polymorphism. Some protection mechanisms are described, including those connected with capturing free radicals, biotransformation of xenobiotics, excision repair of DNA damage (excision of nitrous bases, nucleotides, mismatch repair). A special section is devoted to some issues of using antimutagens in context of genetic polymorphism. The problem of adaptive response is discussed, providing evidence for independence (in some cases) of DNA repair systems and the formation of adaptive response. Some results of the author obtained many years ago but still relevant are presented.

“…However, chromium (VI) electroplating processes produce large volumes of chromium-contaminated toxic waste, air pollution and water contamination which can result in significant induction of cytogenetic damage in electroplating workers [3] and genotoxic effects associated with occupational exposure [4,5] to chromium.…”

Selective area deposition of Tin–Nickel alloy coating – an alternative for decorative chromium plating

Sn-Ni alloy coatings on mild steel substrates produced by selective area deposition process with layer thickness of about 14 lm were investigated with regard to the structural and corrosion properties. X-ray diffraction analysis revealed that the selective area plated Sn-Ni alloy was heterogeneous and composed of NiSn, Ni 3 Sn 2 and Ni 3 Sn 4 phases. Uniform surface coverage of the substrate by granular morphology was observed from SEM and AFM. The alloy composition was determined by X-ray fluorescence (XRF). The corrosion protection performance of Sn-Ni alloy on mild steel was assessed using salt-water immersion and electrochemical corrosion tests. A sharp decrease in I corr and high charge transfer resistance indicated improved corrosion resistant behavior of the selective area deposited Sn-Ni alloy.

“…This was recently shown in a group of workers occupationally exposed to higher doses of chromium compounds, where the 4-month administration of a diet supplementation with a polyvitamin complex reduced the frequency levels of micronuclei in their lymphocytes to basal frequencies [Vaglenov et al, 1999]. In general, the exhaustion of intracellular antioxidants increases the accumulation of the reactive oxygen species; therefore, it is important to supplement with antioxidants [Gate et al, 1999].…”
