The level of alteration in response to the same level of exposure can vary greatly among different ecosystems: in particular, effects provoked by chemicals are not only relying on their “absolute toxicity” and on their concentration, but also on the ecological vulnerability of the system. Vulnerability is often overlooked in current risk assessment procedure, but its knowledge is pivotal in site-specific studies, where the object of the protection is shifted from a generic scenario to a real ecological system. The study of ecological vulnerability confirms that risk assessment, as becoming site-specific, needs more ecological knowledge. In this path, the use of ecological and biological traits of organisms has proven to be a promising approach to evaluate the ecological vulnerability at different level of biological organization. In this work the issue of the ecological vulnerability has been considered from several different perspectives, using multiples methodologies and working at completely different scales. The leading thread is to show how an ecologically based approach can enhance our understanding of environmental processes and thus improving risk assessment methodologies.
