Mercury (Hg) is a toxic heavy metal that causes damage to the central nervous system, alters human behavior, and has an impact on aquatic biota. The aim of this study was to evaluate the bioaccumulation by Hg in fish and the risk for ingestion in an indigenous community (IC) in the Peruvian Amazonia during the dry and rainy season. The community Santa Rosa de Tamaya y Tipishca is located in the lower basin of the Abujao River. The study was carried out with 119 inhabitants grouped into 22 families, with average ages of 9 and 38 years for children and adults, respectively. The fish were collected using mainly trawl nets and were identified following the standard taxonomic morphological procedure. The Hg content in fish muscle was done using atomic fluorescence spectrometry. The results show that the four most consumed fish species by the NC were Pterygoplichthys pardalis (Castelnau, 1855)...
