\description{
Interval-valued dataset of heavy metal concentrations in organs and tissues
of 12 freshwater fish species, grouped into 4 feeding categories (Carnivores,
Omnivores, Detritivores, Herbivores). Contains 13 interval-valued variables
measuring metal concentrations in organs and organ-to-muscle ratios.
