Ở đây, chúng tôi xem xét độc tính của hợp chất cyanide thuỷ sản phụ thuộc động vật hoang dã tiếp xúc thông qua nước uống và thực phẩm. Tập trung của chúng tôi là đánh giá bioavailability1 của cyanide từ khác nhau con đường tiếp xúc và mức độ độc tính thay đổi khi các hợp chất khác nhau xyanua truyền từ đường ruột vào máu. Cụ thể hơn, mục đích của tổng quan này là đánh giá các câu hỏi sau đây:. | 15 Toxicity of Cyanide to Aquatic-Dependent Wildlife Jeremy M. Clark Rick D. Cardwell and Robert W.

Environmental Protection Agency s USEPA ambient water quality criteria AWQC for cyanide were developed in 1984 1 and have been used extensively to develop local water quality standards for protection of aquatic life. New knowledge on the relative toxicity of bioavailable cyanide species and the measurement of cyanide species 2 have prompted a reevaluation of the aquatic toxicity data that serve as the basis of the current national criteria 3 see also Chapter 14 . However AWQC for protection of aquatic life do not necessarily represent concentrations that would be protective of the entire aquatic ecosystem. Consideration also should be given to the sensitivity of wildlife species whose primary habitats are aquatic or are dependent on aquatic life as a food source. Aquatic-dependent wildlife is comprised of waterfowl shorebirds . sandpipers and aquatic mammals . otter beaver . 285 2006 by Taylor Francis Group LLC 286 Cyanide in Water and Soil Here we review the toxicity of cyanide compounds to .
