Examine the Current State of the Science
Surface water sampling programs across the globe have shown the presence of many different classes of medicines. The potential risks associated with the release of these medicines into the environment have become an increasingly important issue for environmental regulators. Effects of Veterinary Medicines in the Environment examines the current state of the science in evaluating the potential risks of veterinary medicines to aquatic and terrestrial ecosystems.
International Panel Provide Guidance
The book brings together more than 30 experts, from eight countries, with expertise in risk assessment, environmental toxicology and chemistry, and environmental policy and regulation. These experts provide guidance, based on standard risk assessment approaches, on how to assess the environmental effects of veterinary medicines. The text discusses pathways to the environment, exposure and effects assessment, and risk assessment and management in terrestrial and aquatic environments. It reviews classes of veterinary medicines and current regulations, identifies the environmental fate of the medicines, and assesses the use of read-across, QSAR, and other modeling approaches.
Detailed Coverage of Technical Approaches
An examination of the current state of the science, the book provides integrated content in a single source. It provides detailed coverage of technical approaches that helps practitioners better understand the environmental risks of veterinary medicines.
