Heavy metal ecotoxicology of vervet monkeys (Chlorocebus pygerythrus) across field sites in South Africa.

Primatologists use ecological models for understanding nonhuman primate (NHP) behavior and biology. Yet few studies have focused on the impacts of naturally occurring and anthropogenically derived toxicants in NHP habitats. For humans and NHPs, toxic levels of heavy metals frequently result in poor health outcomes including improper neurological development, immune system depression, and endocrine disruption.
