Appendix E: Field Scientist Report 



Lagoa dos Patos (04/02/92). Duplicate mussel samples (Perna perna) were collected from 2 



stations located about 500 meters from the mouth of the lagoon. Stations face the open ocean, and 



were collected by hand. Access is by boat. 



Contamination:: Different industries (chemical, oil-related, fertilizer, etc.) discharge wastes into 



the lagoon. The lagoon also receives, directly or indirectly through smaller interconnected 



lagoons, surface waters drained from a large upland area with extensive agriculture. 



CHILE 



Puerto Montt (04/09/92). Puerto Montt, together with Conception, replaced the Valdivia site. 



Samples were obtained from local fishermen/divers. Duplicate samples {Aulacomya ater) were 



obtained from 2 areas in this region: Guar Island and from near the mouth of the Relon Cavi river. 



Duplicate mussel samples were obtained from the station near the mouth of the Relon Cavi river. 



Access to the sampling sites is by boat 



Contamination:: No sources of contamination were observed in the area. 



Punta Arenas (04/10/92). The sampling site is located in front of the city of Punta Arenas about 



1000 meters from the main port. Duplicate mussel samples were collected from 2 stations located 



about 300 meters apart. At one station, an extra sample of Aulacomya ater was collected. Access 



to the site is by car. 



Contamination:: Punta Arenas Port. Domestic effluents. 



Valparaiso (04/12/92). One duplicate sample (Perumytilus purpuratus) was collected during low 



tide at a site located about 100 meters from the port of Valparaiso. Access to the area is by car. 



Contamination:: Port Activities. Industrial and domestic effluents. 



La Serena (04/13/92). Bivalves were depleted in this area. Duplicate mussel samples 



(Aulacomya ater) were obtained from local fishermen/divers who had collected the organisms near 



Quebrada Grande about 4 h earlier. Quebrada Grande is about 20 km to the north of La Serena. 



Access to the area is only by boat. 



Contamination:: Quebrada Grande seems to be a pristine area. 



Arica (04/16/92). At this site, bivalves (Perumytilus purpuratus) were collected from 3 stations 



during low tide. Stations were located about 300 meters apart from each other. Sampling stations 



were located to the south of the main port of Arica. The sampling site is within the city limits and 



access is by car. 



Contamination:: Port activities. Fisheries. Industrial and domestic effluents. 



Antofagasta (04/18/92). As in La Serena, bivalves were not found near the city of Antofagasta, 



Samples (Aulacomya ater) were obtained from local fishermen/divers who collected the organisms 



in Caleta Coloso a few hours earlier. Caleta Coloso is located about 18 km to the south of 



Antofagasta . Access to the sampling site is only by boat. 



Contamination:: Caleta Coloso seems to be a pristine area.
