Concentrations of 10 perfluorinated compounds in water and fish from rivers and lakes in the world were reviewed from the surveys in the years of 1998-2011. A yearly decreasing tendency was recognized in the concentrations of Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) in water from several rivers in Japan. The concentrations of PFOA in water from rivers and lakes in Japan had a tendency to be higher than those of PFOS but the concentration levels of both compounds were equal in Europe. Further, the concentrations of PFOS in water from rivers in Europe and North America were higher than those in Japan and Asia. Composition of the perfluorinated compounds was PFOA >> Perfluorononanoic acid (PFNA) ≧ Perfluorohexanoic acid (PFHxA) in water from rivers and lakes in Japan and PFOS ≧ PFOA in Asia, Europe and North America. Perfluorinated compounds with more carbon atoms were more highly accumulated in fish, and bioconcentration factor (BCF) of PFOS was lower than that of Perfluorododecanoic acid (PFDDA) and nearly equal to that of Perfluoroundecanoic acid (PFUA) or Perflurorodecanoic acid (PFDA). Each of the BCF data of the perfluorinated compounds by field survey data (Field BCF) was nearly in the same order as each of the BCF data by laboratory experimental data (Laboratory BCF). However, absolute values of the Field BCF had a tendency to be higher than those of the Laboratory BCF. To verify this tendency, it is necessary to accumulate additional data on Laboratory and Field BCF and to advance the research development in future on adding the uptake of the compounds via food for the uptake of the compounds via gill in the Field BCF values or on the differences of the environmental conditions.
