Abstract : A literature search was conducted to identify research relating physical and chemical changes associated with navigation traffic to potential biological impacts. It was found that, although some information on physical and chemical changes was available, documentation to demonstrate biological impacts was generally lacking. Where possible impacts were identified, they were observed at the organism level, rather than population, community, or ecosystem level. A particular problem was encountered in attempting to separate impacts of navigation from those caused by natural and/or anthropogenic perturbations. It was concluded that biological impact analysis beyond the organism level may not be within existing state-of-the-art technology. (Author)
