“…Much of the literature regarding heavy metal accumulation in large mammals includes mammals important to the human diet, especially grazers such as cattle (Alonso et al 2003;Cai et al 2009;Miranda et al 2009;Mahajan et al 2012;Roggeman et al 2013), deer (Pokorny and Ribaric-Lasnik 2002;Reglero et al 2008Reglero et al , 2009, and sheep (Phillips and Tudoreanu 2011), as well as omnivores such as wild boar (Sus scrofa; Suidae) (Reglero et al 2009). Exposure to non-essential metals (e.g., Cd, Pb, and As) can cause mutagenesis, carcinogenesis, teratogenesis, immunosuppression, and may inhibit growth, lower fertility and impair reproduction (Swarup and Dwivedi 2002;Alonso et al 2002a;2002b;Mahajan et al 2012).…”

“…The authors suggest that this elevated food intake, combined with a diet of metal-accumulating mushrooms, may explain the seasonal difference in metal accumulation. Again, seasonal variations in large mammal metal concentrations are species-specific and depend on the availability of food, diet compositions, and metal variability within food sources throughout a particular season (Reglero et al 2008;Vermeulen et al 2009;Fritsch et al 2011;Roggeman et al 2013).…”

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.

“…López-Alonso et al [19] pointed out that toxic metal accumulation in animal tissues is directly related to grazing activity, and toxic metal exposure through soil ingestion could be higher than the one through the diet. On the other hand, the choice of food plants may in some cases affect the metal exposure of herbivorous animals more than that reflected by the general contamination level in the area [20,21].…”

Background:Grazing circuits and resources consumed differ strongly throughout the year and within a territory. For this reason, animals' diet composition, as well as their exposure to metals, is variable. No studies have been performed on how habitat use affects the metal concentrations to which sheep and goats reared in serpentine soil areas are exposed. Objective:The aim of the present study was to investigate the metal exposure of grazing animals raised in a serpentine soil area of the north-east of Portugal, taking into account the spatial distribution of metal concentrations in soils and plants. Methods:The habitat use and foraging behaviour of six flocks of sheep and goats were studied. The concentrations of Ca, Mg, Mn, Cr and Ni were determined in the soils and plant species most consumed by those animals. Results:The highest Mg, Mn, Cr and Ni concentrations were found in the soils of the ultramafic complex. Ni concentrations above the recommended threshold for agricultural soils (30 μg/g) were found in some sites. A positive correlation between Ni concentration in soils and plants was found (0.634). Ni concentrations higher than 10 µg/g were found in some samples of the following plant species: Sorghum × drummondii (Steud.) Millsp. & Chase,Quercus rotundifolia Lam., Cytisus multiflorus (L'Hér.) Sweet, Cistus ladanifer L. and Erica scoparia L. Significant differences (p ≤ 0.05) in metal concentrations of the plants most consumed by each flock were observed. Conclusion:Grazing circuits have an important role in the metal exposure of animals raised in this serpentine soil area. 96 The Open Agriculture Journal, 2018, Volume 12 Ramalhosa et al.No studies have been performed on how habitat use affects metal concentrations to which sheep and goats reared in serpentine soil areas are exposed. In order to get knowledge on this subject, in the present work, six herds (three of sheep and three of goats) were followed to find out their grazing circuits and diets. At the same time, soil and vegetation samples were collected, and the metal concentrations (Ca, Mg, Mn, Cr and Ni) in them determined in order to evaluate the animals' metal exposure. In more detail, we want to find out which plant species and grazing circuits are more problematic to animals in terms of heavy metals, namely chromium and nickel. MATERIALS AND METHODS Study Area and Flock DescriptionThe present study was carried out in the Morais region (41° 29' N, 6° 46' W), a serpentinic area in the north-east of Portugal (Fig. 1). The mean annual temperature is 11.9 °C and the mean rainfall is 636 mm [24]. The dry period occurs mainly in July and August. Morais geomorphology is characterized by an undulating plateau (mean altitude 600 m), cut by two rivers, the Azibo and Sabor [25].Extensive livestock farming is one of the main economic activities based on common lands, native pastures and byproducts of agriculture. Subsistence farming is the dominant type of agriculture. Winter cereals (wheat and rye) and spring crops (maize, potatoes or vegetables) are p...

RESUMODentre os estados do Nordeste, a Bahia destaca-se quanto à modernização do processo produtivo agropecuário, sendo a pecuária bovina essencial no agronegócio do Estado. Esta pesquisa objetivou avaliar as concentrações dos elementos químicos Mg, P, Fe, Ca, Mn, Pb e Zn em amostras de diferentes tecidos (músculo, fígado e rim) de bovinos comercializados na cidade de Salvador. Os bovinos tiveram as suas amostras coletadas em frigoríficos soteropolitanos com uma média de 18 exemplares por coleta, seis para cada tecido. Os elementos foram determinados por espectrometria de emissão óptica com plasma indutivamente acoplado (ICP OES). A ordem decrescente de concentração dos elementos em cada tecido foram as seguintes: músculo: P>Mg>Ca>Zn>Fe>Mn>Pb; fígado: P>Mg>Zn>Ca>Fe>Pb>Mn e rim: P>Mg>Ca>Fe>Zn>Pb>Mn. O Pb apresentou valores abaixo do limite de detecção do método (<0,050 mg.kg -1 ) para todos os tecidos de músculos. Entretanto, apresentou concentrações elevadas nos tecidos de fígado (3,71-7,24 mg.kg -1 ) e rim (1,92-3,85 mg.kg -1 ). Os tecidos bovinos podem ser uma boa fonte de elementos químicos essenciais, principalmente, de P, Mg e Fe. As concentrações de elementos que ficaram acima do limite estabelecido pela legislação brasileira foram as de Zn nas amostras de fígado e músculo, e as de Pb nas amostras de fígado e de rim. PALAVRAS-CHAVE: bovinos, composição química, fígado, músculo, rim. ABSTRACTIn the Northeast of Brazil, the modernization of the livestock industry of Bahia stands out. The cattle raising is also an essential part of the agribusiness of the state. This research aimed at evaluating the concentrations chemical elements such as: Mg, P, Fe, Ca, Mn, Zn, Pb in samples of different tissues (muscle, liver and kidney) of cattle marketed in the city of Salvador, Bahia. The cattle had their samples collected in butcher shops of the city of Salvador with an average of 18 copies per collection, six for each tissue. The elements were determined by Optical Emission Spectrometry with Inductively Coupled Plasma (ICP OES). The decreasing order of concentration of elements in each tissue Pb showed values below the method detection limit (<0.050 mg.kg -1 ) for all muscle tissues. However, it presented high concentrations in liver tissue (3.71 to 7.24 mg.kg -1 ) and kidney (1.92 to 3.85 mg.kg -1 ). The bovine tissue can be an excellent source of essential chemical elements, especially, P, Mg and Fe. The concentrations of elements that were above the limit established by Brazilian legislation were Zn in samples of liver and muscle, and Pb in samples of liver and kidney.
