Chronic effects of lead (Pb) on bone properties in red deer and wild boar: Relationship with vitamins A and D3

► We studied the effects of Pb pollution on bone and vitamins in wild ungulates from a mining area. ► Pb decreased the carbonate content in bone mineral in adult red deer. ► Pb increased the ratio of free retinol:retinyl esters in red deer and wild boar. ► Changes in vitamin A status were associated with changes in the carbonate content in bone mineral. ► Adverse effect of Pb on vitamin A status may be involved with toxic effects of Pb in bone tissue.
