“…Metal accumulation in large mammals is tested through both non-destructive samples, such as hair, milk, and blood (Patrashkov et al 2003;Kramarova et al 2005;Rashed and Soltan 2005) and destructive samples such as liver, kidney, and muscle (Cai et al 2009;Miranda et al 2009;Reglero et al 2009). Blood metal concentrations generally reflect more recent exposure and are therefore more useful when the exposure period is short (Wittman and Hu 2002).…”

Heavy metals are released into the environment by both anthropogenic and natural sources. Highly reactive and often toxic at low concentrations, they may enter soils and groundwater, bioaccumulate in food webs, and adversely affect biota. Heavy metals also may remain in the environment for years, posing long-term risks to life well after point sources of heavy metal pollution have been removed. In this review, we compile studies of the community-level effects of heavy metal pollution, including heavy metal transfer from soils to plants, microbes, invertebrates, and to both small and large mammals (including humans). Many factors contribute to heavy metal accumulation in animals including behavior, physiology, and diet. Biotic effects of heavy metals are often quite different for essential and non-essential heavy metals, and vary depending on the specific metal involved. They also differ for adapted organisms, including metallophyte plants and heavy metal-tolerant insects, which occur in naturally high-metal habitats (such as serpentine soils) and have adaptations that allow them to tolerate exposure to relatively high concentrations of some heavy metals. Some metallophyte plants are hyperaccumulators of certain heavy metals and new technologies using them to clean metal-contaminated soil (phytoextraction) may offer economically attractive solutions to some metal pollution challenges. These new technologies provide incentive to catalog and protect the unique biodiversity of habitats that have naturally high levels of heavy metals.

“…Hair is in fact considered a good matrix to be used as a biomarker of exposure to metals, and a good proxy of long term exposures [ 36 , 37 ]. The concentrations of cadmium and lead in hair of cattle with bladder tumors from the present study were below those of normal cattle reared around different industrial/urban areas [ 38 ], and yet the concentrations of lead and chromium were above the levels of those from unpolluted areas [ 39 , 40 ]. Overall, the concentrations of metals found in cases render more investigation on the mechanisms of carcinogenic metals and their role in the development of bladder cancer.…”

BackgroundPrevious studies have provided some evidence of a possible association between cancer and metallothioneins. Whether this relates to an exposure to carcinogenic metals remains unclear.MethodsIn order to examine the association between the expression of metallothioneins and bladder tumors, and to compare the levels of arsenic, cadmium, chromium, lead and nickel in animals with bladder tumors and animals without bladder tumors, 37 cases of bovine bladder tumors and 17 controls were collected. The detection and quantification of metallothioneins in bladder tissue of both cases and controls was performed by immunohistochemistry. And the quantification of metals in tissue and hair was assessed by inductively coupled plasma – mass spectrometry.ResultsIncreased expression of metallothioneins was associated with bladder tumors when compared with non-tumoral bladder tissue (OR = 9.3, 95% CI: 1.0 – 480). The concentrations of cadmium, chromium, lead and nickel in hair of cases were significantly higher than those of controls. However, as for the concentration of metals in bladder tissue, the differences were not significant.ConclusionThough the sample size was small, the present study shows an association between bladder tumors and metallothioneins. Moreover, it shows that concentrations of metals such as cadmium, chromium, lead and nickel in hair may be used as a biomarker of exposure.

Ключевые слова: герефордская порода, тяжелые металлы, печень, быки. Животноводство -важнейшая отрасль сельского хозяйства. Оно занимает ведущее место в народнохозяйственном комплексе России. От уровня его развития во многом зависит способность удовлетворения первоочередных материальных потребностей общества и продуктовая безопасность, так как главная задача животноводства -производство необходимого количества продуктов питания для населения и сырья для промышленности [7-10, 18, 19, 27,36]. Актуальность экомониторинга заключается в том, что поступление значительной части токсикантов в организм человека в основном происходит по системе: почва -растение (корм, рацион) -животное -продукт животноводства -человек [30,31,41].
