This paper describes ecological characteristics of the western sand extraction area off the Belgian coast. A review of scientific research is given with special reference to a long term ecological monitoring programme.Relevant clauses concerning the exploration and exploitation of the Belgian continental shelf were elaborated in the law of 13 June 1969. In application to this law two Royal Decrees were published to regulate exploitation.The ecological monitoring programme investigated benthic communities and demersal fish population since 1977. Close attention was paid to the evolution of dominant species belonging to the epibenthic fauna e.g. the brittle stars (<i>Ophiura texturata</i> and <i>Ophiura albida</i>), the common... |

Polychlorinated biphenyls (PCBs) and some organochlorine pesticides we re measured in some marine organisms of different trophic levels, sampled in the Belgian coastal waters. Because of their persistence and their lipophilic character they accumulate in lipoidal tissues, causing higher organochlorine residue levels in animals with a high adiposity. To compare the residue levels of different organisms lipid based data must be used.The concept of biological magnification controlled by mass transfers of residues through food chains is questioned because predatory fish like cod contained similar or even lower residue levels than organisms of a lower trophic levellike the peacock worm. This supports the concept that the organochlorine levels are controlled by... |
