ATSDR Toxicological Profile for Vanadium - Succinctly characterizes the toxicologic and adverse health effects information.

Ranking: 32 (total points: 1350.95)

Vanadium toxicity is a challenging problem to human and animal health with no entire understanding of cytotoxic mechanisms. Previous studies in vanadium toxicity showed involvement of oxidative stress in isolated liver hepatocytes and mitochondria via increasing of ROS formation, release of cytochrome c, and ATP depletion after incubation with different concentrations (25-200 uM). Therefore, we aimed to investigate the protective effects of Sesamum indicum seed extract (100-300 ug/mL) against oxidative stress induced by vanadium on isolated rat hepatocytes. Our results showed that quite similar to Alpha-tocopherol (100 uM), different concentrations of extract (100-300 ug/mL) protected the isolated hepatocyte against all oxidative stress/cytotoxicity markers induced by vanadium in including cell lysis, ROS generation, mitochondrial membrane potential decrease and lysosomal membrane damage. Besides, vanadium induced mitochondrial/lysosomal toxic interaction and vanadium reductive activation mediated by glutathione in vanadium toxicity was significantly (p<0.05) ameliorated by Sesamum indicum extracts. These findings suggested a hepato-protective role for extracts against liver injury resulted from vanadium toxicity.

IDENTIFICATION AND USE: Pure vanadium is a bright white metal. Vanadium is used in producing rust-resistant, spring, and high-speed tool steels. It is an important carbide stabilizer in making steels. Vanadium-containing catalysts are used in several oxidation reactions such as the manufacture of phthalic anhydride and sulfuric acid as well as in the production of pesticides and black dyes, inks, and pigments, which are used by the textile, printing, and ceramic industries. An important use of vanadium is as an oxidation catalyst in automobile catalytic converters. Other minor functions of vanadium compounds include their use as color modifiers in mercury-vapor lamps, driers in paints and varnishes, corrosion inhibitors in flue-gas scrubbers, and as components in photographic developers. Future application of vanadium compounds may include an increased number of uses as a catalyst, a potential role in superconductors, thermal or light-activated resistor-conductors, vanadate glasses, elecrooptical switches, and the induction of high magnetic fields. HUMAN EXPOSURE AND TOXICITY: Acute Overdosage: Headache, CNS depression, dry mouth, metallic taste, green tongue, abdominal pain, diarrhea, black stools, ocular irritation, occupational asthma, pulmonary edema, tracheitis, rhinitis, epistaxis, peripheral vasoconstriction of lungs, spleen, kidney, intestine, and dermatitis. Cross-sectional study recruited 533 vanadium exposed workers and 241 non-exposed workers to provide human evidence on serum lipid, lipoprotein profiles and atherogenic indexes changes in relation to vanadium exposure. Among male workers, a significantly negative association existed between low HDL-C level, abnormal atherogenic index and occupational vanadium exposure. This suggests vanadium has beneficial effects on blood levels of HDL-C and apoA-I. However, the other study found evidence of altered neurobehavioral outcomes by occupational exposure to vanadium. ANIMAL STUDIES: Some experimental animal studies reported that vanadium had beneficial effects on blood total cholesterol (TC) and triglyceride (TG). ECOTOXICITY STUDIES: Adult porpoises displayed significant higher concentrations of vanadium in livers compared to juveniles. Trace concentrations of vanadium have several benefits for plant growth, but high concentrations are toxic.

Vanadium damages alveolar macrophages by decreasing the macrophage membrane integrity, thus impairing the cell's phagocytotic ability and viability. The pentavalent form of vanadium, vanadate, is a potent inhibitor of the Ca+-ATPase and Na+,K+-ATPase of plasma membranes, which decreases intracellular ATP concentration. Vanadium is also believed to induce the production of reactive oxygen species. This may damage DNA and also cause oxidative stress, which can damage the reproductive system. Vanadium also inhibits protein tyrosine phosphatases, producing insulin-like effects. (L837, A247, A248, A249, A250, A251)

The assessment of vanadium exposure can be accomplished through measurement of vanadium. This test may be useful for assessing /exposure/ to larger than normal amounts of vanadium, but there was no information found in the literature showing a correlation of these levels with environmental levels or onset of clinical effects. Blood Reference Ranges: Normal - less than 1 ug/L; Exposed - not established; Toxic - not established. Serum or Plasma Reference Ranges: Normal - less than 0.24 ug/L; Exposed - not established; Toxic - not established. Urine Reference Ranges: Normal - 0.06 to 0.87 ug/L; Exposed - Workers exposed to average 8 hr air concentrations of 6.0 to 6.4 mg/cu m had urine vanadium levels between 2.6 to 4.6 ug/L in specimens that were collected at the start of the next work day. BAT for vanadium pentoxide (sampling time for long term exposures: after several shifts, measured as vanadium): 70 ug/g creatinine; Toxic - In a study involving controlled human exposure to vanadium pentoxide, where levels caused development of mild respiratory effects, the peak urine vanadium level was 130 ug/L at 3 days after exposure. /Vanadium/

Pulmonary Function Tests: The tests that have been found to be practical for population monitoring include: spirometry and expiratory flow-volume curves; determination of lung volumes; diffusing capacity for carbon monoxide; single-breath nitrogen washout; inhalation challenge tests; serial measurements of peak expiratory flow; exercise testing. /Vanadium/

/SIGNS AND SYMPTOMS/ Signs & Symptoms of Acute Overdosage: Headache, CNS depression, dry mouth, metallic taste, green tongue, abdominal pain, diarrhea, black stools, ocular irritation, occupational asthma, pulmonary edema, tracheitis, rhinitis, epistaxis, peripheral vasoconstriction of lungs, spleen, kidney, intestine, /and/ dermatitis.

/EPIDEMIOLOGY STUDIES/ Vanadium-containing products are manufactured and widely used in the modern industry. Yet the neurobehavioral toxicity due to occupational exposure to vanadium remained elusive. This cross-sectional study was designed to examine the neurotoxic effects of occupational vanadium exposure. A total of 463 vanadium-exposed workers (exposed group) and 251 non-exposed workers (control group) were recruited from a Steel and Iron Group in Sichuan, China. A WHO-recommended neurobehavioral core test battery (NCTB) and event-related auditory evoked potentials test (P300) were used to assess the neurobehavioral functions of all study subjects. A general linear model was used to compare outcome scores between the two groups while controlling for possible confounders. The exposed group showed a statistically significant neurobehavioral alteration more than the control group in the NCTB tests. The exposed workers also exhibited an increased anger-hostility, depression-dejection and fatigue-inertia on the profile of mood states (p<0.05). Performances in the simple reaction time, digit span, benton visual retention, and pursuit aiming were also poorer among exposed workers as compared to unexposed control workers (p<0.05). Some of these poor performances in tests were also significantly related to workers' exposure duration. P300 latencies were longer in the exposed group than in the control (p<0.05). Longer mean reaction times and more counting errors were also found in the exposed workers (p<0.05). Given the findings of our study and the limitations of neurobehavioral workplace testing, we found evidence of altered neurobehavioral outcomes by occupational exposure to vanadium.

/EPIDEMIOLOGY STUDIES/ Some experimental animal studies reported that vanadium had beneficial effects on blood total cholesterol (TC) and triglyceride (TG). However, the relationship between vanadium exposure and lipid, lipoprotein profiles in human subjects remains uncertain. This study aimed to compare the serum lipid and lipoprotein profiles of occupational vanadium exposed and non-exposed workers, and to provide human evidence on serum lipid, lipoprotein profiles, and atherogenic indexes changes in relation to vanadium exposure. This cross-sectional study recruited 533 vanadium exposed workers and 241 non-exposed workers from a Steel and Iron Group in Sichuan, China. Demographic characteristics and occupational information were collected through questionnaires. Serum lipid and lipoprotein levels were measured for all participants. The ratios of total cholesterol to high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) to HDL-C and apoB to apoA-I were used as atherogenic indexes. A general linear model was applied to compare outcomes of the two groups while controlling possible confounders and multivariate logistic regression was performed to evaluate the relationship between low HDL-C level, abnormal atherogenic index, and vanadium exposure. Higher levels of HDL-C and apoA-I could be observed in the vanadium exposed group compared with the control group (P<0.05). Furthermore, atherogenic indexes (TC/HDL-C, LDL-C/HDL-C, and apoB/apoA-I ratios) were found statistically lower in the vanadium exposed workers (P<0.05). Changes in HDL-C, TC/HDL-C, and LDL-C/HDL-C were more pronounced in male workers than that in female workers. In male workers, after adjusting for potential confounding variables as age, habits of smoking and drinking, occupational vanadium exposure was still associated with lower HDL-C (OR 0.41; 95% CI, 0.27-0.62) and abnormal atherogenic index [odds ratio (OR) 0.38; 95% CI, 0.20-0.70]. Occupational vanadium exposure appears to be associated with increased HDL-C and apoA-I levels and decreased atherogenic indexes. Among male workers, a significantly negative association existed between low HDL-C level, abnormal atherogenic index and occupational vanadium exposure. This suggests vanadium has beneficial effects on blood levels of HDL-C and apoA-I.

Vanadium metal can be prepared either by the reduction of vanadium chloride with hydrogen or magnesium or by the reduction of vanadium oxide with calcium, aluminum, or carbon. The oldest and most commonly used method for producing vanadium metal on a commercial scale is the reduction of V2O5 with calcium. Recently, a two-step process involving the aluminothermic reduction of vanadium oxide combined with electron-beam melting has been developed. This method makes possible the production of a purer grade of vanadium metal, i.e., of the quality required for nuclear reactors.

... Vanadium can be purified by ... iodide refining (van Arkel-deBoer process), electrolytic refining in a fused salt, and electrotransport. Metal of greater than 99.95% purity has been prepared by the iodide refining method. ... An electrolytic process for purifying crude vanadium was developed at the USA Bureau of Mines. ... Metal crystals or flakes of up to 99.995% purity have been obtained by this method. The highest purity vanadium reported has been purified by an electrotransport technique. ... Small amounts of vanadium containing less than 10 ppm of carbon, oxygen, and nitrogen and having a resistance ratio, R300 K:R4.2 K, of greater than 1100 have been prepared by this technique.

(1) Calcium reduction of vanadium pentoxide yields 99.8+% pure ductile vanadium; (2) aluminum, cerium, etc., reduction produces a less pure product; (3) solvent extraction of petroleum ash or ferrophosphorus slag from phosphorus production; (4) electrolytic refining using a molten salt electrolyte containing vanadium chloride.

Vanadium powder can be prepared by substituting V2O3 for the V2O5 as the vanadium source. The heat generated during the reduction of the trioxide is considerably less than for the pentoxide, so that only solid products are obtained. The powder is recovered from the product by leaching the slag with dilute acid.

Vanadium: ACTIVE

The United States dominated world vanadium production for all uses until the late 1960s when several countries, notably the former USSR, expanded production significantly. At about the same time, the United States shifted from being a net exporter to a net importer; this situation continues.

Steels containing various combinations of other alloying elements can be substituted for steels containing vanadium. Certain metals, such as manganese, molybdenum, niobium (columbium), titanium, and tungsten, are to some degree interchangeable with vanadium as alloying elements in steel. Platinum and nickel can replace vanadium compounds as catalysts in some chemical processes. Currently, no acceptable substitute for vanadium is available in aerospace titanium alloys.

Some tool steel scrap was recycled primarily for its vanadium content. Vanadium was also recycled as a minor component of scrap iron and steel alloys, which were used principally for their iron content.

The steel industry accounts for the majority of the world's consumption of vanadium as an additive to steel. It is added in the steelmaking process as a ferrovanadium alloy ...
