“…The meat and milk of the animals are one of the major sources of protein to the people. Bioaccumulation of Cu and other trace metals in the liver of cattle has been reported (Nwude et al 2011 However, all the levels obtained were higher than 4.60 mg/kg of Cu obtained at the control site (CS). The high level of Cu obtained at SCP1 compared to the others might be due to the fact that more anthropogenic events such as industrial activities are observed in this area.…”

Anthropogenic activities often result in the introduction of noxious contaminants into the environment with resultant distribution and transfer across the food chain. This study reports on the level of trace metals (Cd, Pb, Cu and Zn) in African foxtail (Cenchrus ciliaris) plant; widely referred to as "common grass" and possible implication across the food chain. Plant samples were collected from stratified study area, processed and analysed using validated acid leaching protocols. Instrumental analysis of the metallic content was by ICP-OES. Quality assurance of the analytical protocol revealed its' applicability to the environmental samples through metallic recoveries (n=3) in the range of 85.6 -91 %. The overall mean concentration of analysed metals in samples ranged from 9.34 mg/kg -38.6 mg/kg; 64.2 mg/kg -105.2 mg/kg; 0.28 mg/kg -0.73 mg/kg and 0.54 mg/kg -16.3 mg/kg for Cu, Zn, Cd and Pb respectively across SCP1-SCP4. Incremental order of analysed trace metals across the SCPs were Cu: SCP1>SCP2>SCP3>SCP4; Zn: SCP1>SCP2>SCP3> SCP4; Cd: SCP1>SCP2>SCP3 = SCP4 and Pb: SCP1>SCP2> SCP3>SCP4. Strong correlation (r > 0.99) was obtained between all the analysed trace metals. Significant difference at (p < 0.05) was found between the analysed metals and SCP 1 while those between the metals and SCPs 2-4 were non-significant. Accumulation of these metals in ruminants and transfer across the food chain is most probable.

“…Las concentraciones hepáticas de metales pesados en ganado bovino también han sido evaluadas por otros investigadores. (31). Las concentraciones de Cu (0.17-177.30 µg/g) reportadas en este estudio en hígado de bovinos, están igualmente en acuerdo con los reportes descritos, destacando las diferencias con el valor registrado por Liu (28).…”

Objetivo. Evaluar la presencia de metales pesados: plomo(Pb), cobre (Cu), cadmio (Cd) y mercurio (Hg) en hígado y músculo pectoral derecho de bovino, procedentes de fincas de la zona del Sinú y San Jorge. Materiales y métodos. Se muestrearon bovinos machos, adultos, de raza cebú mestizo, entre 2 a 7 años los cuales fueron sacrificados para consumo humano durante seis meses. Las muestras se analizaron mediante: espectroscopia de absorción atómica, empleando lámparas de cátodo hueco y un quemador de aire acetileno para determinar Cu; vapor frío para la detección de Hg y polarografía para la detección de Cd y Pb. Resultados. Se observó que Los rangos de Hg, Cu, Cd y Pb estaban por debajo de los parámetros de referencia de la Comisión Europea y la Norma Oficial Mexicana. En el 4% de las muestras se encontraron niveles de Cu no permisibles para consumo humano. Conclusiones. La industria cárnica de la región presenta una gran potencialidad para acceder a mercados internacionales, debido a que el 96% de las reses presentaron niveles de metales por debajo de los límites permisibles de México y Europa. A pesar de que los niveles de mercurio se encuentran en los límites permisibles, la evaluación del riesgo basado en el índice de peligrosidad, sugiere que el consumo diario de 100 gramos de productos cárnicos con niveles de 0.08 ppm, podría incrementar el riesgo de envenenamiento a una persona de 70Kg

“…Серед металів, що відносно рівномірно розподіляються в організмі, зазвичай реєструється найвищий їх вміст в органах, де зосереджені інтенсивні біохімічні процеси: у печінці, залозах внутрішньої секреції, нирках (López- Alonso et al, 2000;Suttle, 2010;Nwude et al, 2011). Дослідники повідомляють (Jarzyńska & Falandysz, 2011), що печінку слід розглядати як потужне джерело таких мікроелементів, як Co, Cr, Cu, Mo, Mn, Se і Zn, які накопичуються в організмі жуйних тварин у межах трофічного ланцюга.…”

“…Автори наголошують, що печінка великої рогатої худоби стає потенційно небезпечним органом для здоров'я людей у разі акумуляції в ньому важких металів. Крім того, науковці зазначають, що виявлення концентрації одного металу може свідчити про рівень накопичення іншого (Nwude et al, 2011). На думку науковців, печінка акумулює максимальну кількість таких мікроелементів як Cu, Mn і Md, тому її використовують як орган-мішень для виявлення цих металів (Oymak et al, 2017).…”

The concentration of chemical ements (Pb, Cd, Cu, As, Zn, Hg, Fe, Co, Mn) in the liver of healthy cattle and those affected by Fasciola hepatica and Dicrocoelium lanceatum in Poltava region (central part of Ukraine) was determined. The research was carried out by the method of atomic and absorption spectrometry carried out at the Regional State Laboratory of Veterinary Medicine in Poltava region. The liver samples (n = 30) from healthy cattle black-and-white breed and those affected by F. hepatica and D. lanceatum were taken at the meat processing plant. The ages of the cattle ranged from 6 to 8 years. The samples were immediately cooled, transported to the laboratory and stored at –20 °C for further analysis. The results of the research determined the average indicators of concentration of some toxic elements in the livers of healthy cattle and those infected by the trematodes. The content of chemical elements in the liver of healthy animals and those affected by fasciola can be represented in the form of a decreasing rank number: Zn > Fe > Cu, and for dicrocoeliosis, respectively, Fe > Zn > Cu. It has been established that Cu and Zn are involved in the metabolic processes of the body of trematodes, which is confirmed by our research. The presence of F. hepatica and D. lanceatum in the body of cattle significantly reduces the level of copper and zinc, with a high inverse correlation dependence on the intensity of infection, thus indicating the possibility of their accumulation by helminths. Concentration of Cu and Zn in the liver of cattle with fasciolosis was 6.82 ± 0.29 and 35.77 ± 1.93 mg/kg, while for animals with dicrocoeliosis it was 3.90 ± 0.25 and 41.91 ± 2.22 mg/kg. The content of cobalt and manganese in the liver of healthy animals was, respectively, 0.05 ± 0.01 and 1.95 ± 0.06 mg/kg. In the case of Fasciola parasitising in the liver tissue, the level of cobalt (0.10 ± 0.02) and manganese (2.55 ± 0.16) significantly increased, positively correlating with the intensity of the infection, indicating no effect on the exchange and bioaccumulation of these elements by helminths.
