Blood lead and zinc concentrations of four small carnivore species native to Taiwan include small Indian civet (Viverricula indica), masked palm civet (Paguma larvata), ferret badger (Melogale moschata), and crab-eating mongoose (Herpestes urva) from urban and rural areas (Yangmingshan National Park, Xiuguluan River bank, and Da-an River bank). To assess the threat of lead and zinc contamination in the environment and within native wildlife, animals were captured between 2012 and 2018 to compare blood zinc and lead concentrations in 1) animals from the same habitat but different ecological niches and 2) animals from different habitats that represent different levels and types of human activity. The P values refer to the significance of differences within each species in different areas and among different species within the same area.^a
