Correlations between elements in the fur of wild animals

Area of Science:

• Environmental Science
• Zoology
• Analytical Chemistry

Background:

• Limited data exists on the elemental composition of wild animal fur.
• Understanding elemental profiles in wildlife is crucial for assessing environmental health.
• Fur may serve as a non-invasive sampling matrix for toxicological studies.

Purpose of the Study:

• To determine the concentration of various elements in the fur of roe deer, wild boar, and hare.
• To investigate potential correlations between elemental fur content and tissue concentrations.
• To evaluate the utility of wild animal fur as a biomarker for element bioavailability and environmental exposure.

Main Methods:

• Atomic absorption spectrometry was employed to quantify element levels.
• Analysis included calcium, magnesium, zinc, copper, iron, manganese, lead, cadmium, aluminium, chromium, and nickel.
• Correlations were examined between fur, liver, and muscle tissue elemental data.

Main Results:

• Element concentrations in fur ranged from 0.01 μg/g (cadmium) to 1,519 μg/g (calcium).
• Significant correlations were observed for manganese, aluminium, calcium, lead, chromium, and nickel between fur and tissues.
• These findings suggest fur reflects internal elemental burdens.

Conclusions:

• Wild animal fur can provide valuable information on element bioavailability and environmental exposure.
• Fur analysis is a promising, non-invasive method for biomonitoring in wildlife.
• Further research is recommended to fully establish fur as a reliable ecological biomarker.
