Concentrations of strontium, barium, cadmium, copper, zinc, manganese, chromium, antimony, selenium and lead in the equine liver and kidneys.

Abstract: The concentrations of specific elements in the equine liver and kidneys are of practical relevance since horses are not only food-producing animals, but also partially serve as an indicator for the environmental pollution, as the basic feed includes plants like grass, grain and fruits. In this study, the concentrations of strontium (Sr), barium (Ba), cadmium (Cd), copper (Cu), zinc (Zn), manganese (Mn), chromium (Cr), antimony (Sb), selenium (Se) and lead (Pb) were measured in the liver, renal cortex and renal medulla of 21 horses (8 male; 13 female; aged between 5 months-28 years), using inductively coupled plasma mass spectrometry. Comparable Cu and Zn concentrations were detected in the liver and renal cortex, while approximately 50% lower concentrations were measured in the renal medulla. The lowest Sr, Cd and Se, but the highest Mn, Sb and Pb concentrations were measured in the liver. The Ba concentrations were comparable in the renal cortex and medulla, but lower in the liver of the horses. Gender-related differences were observed for Cd, Mn and Cr, with higher Cd concentrations in the liver, but lower Mn concentrations in the renal cortex and lower Cr concentrations in the renal medulla of female horses. Age-related differences were detected for most measured elements, however, the animal number per age-group was only low. In conclusion, the present study provides important reference data for the storage of Sr, Ba, Cd, Cu, Zn, Mn, Cr, Sb, Se and Pb in the liver and kidneys of horses, which are of practical relevance for an evaluation of the exposure of horses to these elements, either via feed or the environment.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research article presents findings on the concentration of various elements in horse liver and kidneys. The study not only offers important information for food safety but also contributes to our understanding of environmental pollution.

Objective of the study

  • The study was aimed at investigating the concentrations of select elements—strontium, barium, cadmium, copper, zinc, manganese, chromium, antimony, selenium, and lead—in the liver and kidneys of horses.
  • The importance of the study draws from the dual role of horses—as food producers and partial indicators of environmental pollution. It is believed that horses’ consumption of plants that may retain contaminants from the environment, like grass, grain, and fruits, allows such elements to become detectable in their organ tissues.
  • The findings offer valuable references in the evaluation of horses’ exposure to these elements, whether through feed or the environment.

Methodology

  • The research used the organs of 21 horses—8 males and 13 females—all of different ages (ranging from 5 months to 28 years).
  • The method employed for the measurement of the element concentrations was inductively coupled plasma mass spectrometry—a highly sensitive analytical technique for trace and ultra-trace element analysis.

Findings and Conclusion

  • The study found comparable copper and zinc concentrations in the liver and renal cortex of the horses, while approximately 50% lower concentrations were found in the renal medulla.
  • Results showed the lowest strontium, cadmium, and selenium concentrations in the liver but the highest manganese, antimony, and lead concentrations there.
  • Barium concentration was nearly the same in the renal cortex and renal medulla but lower in the liver.
  • Gender-related differences were reported with higher cadmium concentrations in the liver, lower manganese concentrations in the renal cortex, and lower chromium concentrations in the renal medulla of female horses.
  • The age of the horse had a notable effect on the concentration of most of the elements measured. However, the sample size for each age group was relatively small.
  • The findings of the study present vital data regarding the storage of the ten mentioned elements in horse liver and kidneys, supporting the need for more focused studies for environmental and food safety.
