Congenital limb malformations in the free-ranging macaques of Kowloon.

This paper describes the instances of gross hand and limb malformations in the free-ranging macaques in the forested region of the Kowloon peninsula of Hong Kong. The incidence in this location is compared to that of other macaque groups, most notably the Japanese and rhesus macaques in free-ranging and captive conditions. Etiology is linked to what is known about suspected local teratogenic agents, particularly in pesticides and fuel emissions.
