“…This could be attributed to the evolution of hydrogen, oxygen gas, chromic acid mists, and nickel fumes during the electroplating operation. The current study results agreed with that of Jeyamala et al 21 who found an increased prevalence of allergic bronchitis (17%), nasal irritation (35%), and allergic reactions of the skin (4.2%) among workers exposed to chromium and nickel in electroplating industries located in Madurai city, South India. A study by Were et al 22 found an increased incidence of wheezing, shortness of breath, and sneezing attacks among workers exposed to chromium and nickel in welding and leather tanning industry, in Kenya.…”

Using chromium and nickel for electroplating is important in many industries. This process induces variable adverse health effects among exposed workers. The aim of this study is to detect the genotoxic effects of combined exposure to chromium and nickel among electroplating workers. This study was conducted on 41 male workers occupationally exposed to chromium and nickel in the electroplating section of a factory compared to 41 male nonexposed individuals, where full history and clinical examination were performed. Laboratory investigations included measurement of serum chromium, nickel, 8-hydroxydeoxyguanosine (8-OHdG), and micronuclei were measured in buccal cells. In exposed workers, serum chromium ranged from 0.09 to 7.20 µg/L, serum nickel ranged from 1.20 to 28.00 µg/L, serum 8-OHdG ranged from 1.09 to12.60 ng/mL, and these results were statistically significantly increased compared to nonexposed group ( P < 0.001). Electroplaters showed higher frequencies of micronuclei in buccal cells when compared to nonexposed (ranged from 20.00 to 130.00 N/1,000 versus 2.00 to 28.00 N/1,000; P < 0.001). Linear regression models were done to detect independent predictors of 8-OHdG and micronucleus test by comparing exposed and nonexposed groups. The model found that exposure to chromium and nickel increases serum 8-OHdG by 4.754 (95% confidence interval [CI]: 3.54-5.96). The model found that exposure to chromium and nickel increases micronucleus by 35.927 (95% CI: 28.517-43.337). Serum 8-OHdG and micronucleus test in buccal cells were increased with combined exposure to chromium and nickel. The current research concluded that workers exposed to nickel and chromium in electroplating industry are at risk of significant cytogenetic damage.

“…Electroplating industries are known as a considerable heavy metal discharger to the environment. [5,6] Heavy-metal-contaminated environment has a potential danger for all the organisms living there. The electroplating workers are commonly exposed to the danger of poisoning caused by nickel and the other heavy metals such as chromium, cadmium, vanadium, etc.…”

“…Before the discharge of the electroplating solutions to environment at the end of electroplating process, Cr(VI) is reduced to Cr(III) by addition of sodium metabisulfite to convert more hazardous species of chromium to less hazardous one. [5,[10][11][12] Nickel is exposed to same operation together with hexavalent chromium. But nickel cannot be reduced to another oxidizing step due to its chemical nature.…”

“…Heavy metals, especially nickel, chromium, lead, and cadmium, affect the human metabolism and cause serious health problems and sickness, which can range from cardiovascular problems to many different type of cancer. [5,[7][8][9] Electroplating process is generally applied for coating the metal or non-metal tools and flashlight batteries. Electroplating sludge can occur as a waste of electroplating industries.…”

The study was conducted to investigate synergistic extraction of nickel from simulated spent Cr-Ni electroplating bath solutions by emulsion liquid membrane (ELM) process using 5,8-diethyl-7-hydroxydodecan-6-one oxime (LIX 63) and 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (PC88A) as carriers. The importance of ELM composition and the properties of simulated spent electroplating bath solution have been optimized to synergistically extract nickel. The important parameters affecting the nickel extraction efficiency and ELM stability, such as acid concentration, stripping solution type and concentration, extractant concentration, surfactant concentration, and phase ratio, were experimentally studied. Along with obtained 1309 Downloaded by [New York University] at 18:44 15 May 2015 results, higher than 99% of nickel was selectively extracted within 30 minutes from simulated electroplating bath solutions that their metal concentrations was in the range of 100-500 mg/L. in the optimum conditions. The higher separation factor value of nickel over chromium (b Ni/Cr ) was obtained as 898. As a result, the nickel extraction kinetic was found to depend on PC88A, since extraction mechanism of PC88A is slower than that of LIX63. So, the combined use of LIX63 and PC88A improved the selective extraction of nickel in that process.

“…Cr(III) is also an essential nutrient element for mammal metabolism. Cr(VI) has also been classified as a carcinogenic, mutagenic and oxidative substance that its uses and discharge limits have to be strictly constrained by governmental authorities, according to the report of the IARC (International Agency for Research on Cancer) . In today, unhazardous chromium species can even turn to hazardous anionic forms of chromium in dilute and concentrated acidic aquatic medium as

This study is to perform the comprehensive investigation of PVC based ionic plasticized membrane (IPM) production by using room temperature ionic liquid (RTIL)‐based additives and the membrane application of selective Cr(VI) removal. Some significant parameters related to membrane structures that are membrane thickness, plasticizer rate, and type, RTILs rate, and type, the average molecular weight of PVC were studied to define the excellent polymeric membrane film composition. After that, the PVC based polymeric film used in the Cr(VI) transport and initial mass transfer coefficient (Jo) were about 3.57 × 10−7 mol s−1 m−2 by decyl substituted RTIL as an additive. Also, optimized membrane transport process has been considered as selective enough for Cr(VI) in the presence of the other heavy metal ions. Surface characterizations of the membranes have been performed to clarify the structural and the morphological assessment of IPMs at initial and end of Cr(VI) transport by SEM‐EDX, AFM, contact angle measurement and found a good relationship between the molecular structure of RTIL additive and membrane morphology. As we know that lots of researchers are still trying to find environmentally friendly, inexpensive and straightforward processes to remove toxic substances from industrial effluents or natural sources. At that point, our results can open a gate for cheap, novel and environmentally friendly Cr(VI) removal by PVC based membrane. J. VINYL ADDIT.
