Abstract
- Biological monitoring of trace element horses is a well-known tool for investigating potential bioaccumulation in urbanized and industrialized geographical areas. Some biomaterials such as hoof are considered as an important indicator of environmental pollution. Hooves can store trace elements for a long time compared to blood and this represents a scientific key to long-term monitoring of exposure to environmental pollutants. In the present study, samples of equine hoof and blood were taken from an experimental group of horses living in an industrialized area of Sicily (Italy) and from a control group of horses housed in a non-industrialized area of Sicily to evaluate the bioaccumulation of different trace elements in different substrates. Hoof and blood mineral concentration of Li- Lithium, Cu- Copper, Zn- Zinc, Sr- Strontium and, Pb- Lead was processed by means of Thermo Scientific iCAP-Q ICP–MS spectrometer. Student T-test was applied to evaluate the differences between groups and substrates. Correlation analysis between substrates and hematological parameters was performed. Statistical analysis showed a significant statistical difference for Li (p < 0.0001) and Pb (p < 0.0001) between blood and hoof in both groups. A statistically significant difference was observed for Li (p < 0.0001), Cu(p < 0.01), Zn (p < 0.0001) and Pb (p < 0.0001) between substrates in the experimental group. The statistical analysis showed a significant difference of blood Zn (p < 0.01) and hoof Pb (p < 0.01) concentration between groups. Our results revealed a statistically higher concentration of minerals in the blood substrate than in the hoof in both groups. Li (p < 0.0001) and Zn (p < 0.001) were positively correlated between control and experimental group in blood substrate. No correlations were found (P >.05) in hoof between groups for other elements. A positive correlation with WBC was observed in Cu concentration for hoof substrate (p < 0.02) in control group and for Zn in experimental group (p < 0.02). A positive correlation with HGB and HCT was observed for Cu hoof concentration (p < 0.02) in experimental group and PLT resulted positively correlated (p < 0.02) with Pb blood substrate in control group. Horses were not overexposed to these elements in the analyzed groups. The study highlights the role of a new bioaccumulation substrate such as the horse hoof identified as an analytical matrix for the monitoring of heavy metal concentrations in domestic animals.
