The Role of the Ocean in Global Cycling of Persistent Organic Contaminants

Persistent organic contaminants, which are bioaccumulative and toxic are a concern for the ecosystems and human health and are regulated under international law (global and regional conventions, besides other). If semivolatile, they cycle in different env

Foreword

The global ocean serves as a repository for long-lived anthropogenic, so-called persistent chemicals. Inputs are riverine runoff and atmospheric deposition. Therefore, pollution is not limited to the marginal seas. Extremely low concentrations are expected in open seawater, but many organic substances tend to accumulate in biota, both fauna and Àora, and the more the higher the trophic level along the marine food chain (bio-accumulation). This has caused detrimental effects in marine wild life and poses a hazard for human health. The causative substances are called persistent organic pollutants (POPs). Since recent years the protection of the marine (and total) environment against POPs has been the subject of internationally binding legislation. Science is developing tools with the aim to predict the behaviour and distribution of old and new (and even non-existing) chemicals and quantify environmen
