External report - Pre-assessment of environmental impact of zinc and copper used in animal nutrition

Copper and zinc are routinely used as additives in feed for livestock and aquaculture farming. During their use as feed additives, it is inevitable that Cu and Zn will be released to the environment. Under Regulation (EC) 1831/3003 (EC, 2003), in order to protect human health, animal health and the environment, feed additives should undergo a safety assessment through a Community procedure before being placed on the market, used or processed within the Community. This project therefore assessed the environmental impact of Cu and Zn arising from use as additives in feed for livestock and aquaculture animals.
