Abstract This study aimed to analyze the bioaccumulation of chromium (Cr) in the meat of tilapia (Oreochromis niloticus L) due to exposure to tannery wastewater. The wastewater concentration variations were 1.85% and 3.69% of the LC50 96-h. The study was carried out in triples, seven days of acclimatization, and 30 days of observation (exposed to wastewater). The measurement of Cr using Atomic Absorption Spectrophotometry (AAS) and calculation of BCF states the level of bioaccumulation in fish meat. The result showed the BCF value at a concentration of 1.85%, and 3.69% ranged 2.667-40.984, and 2.667-85.651 consecutively. It concluded that tilapia has a low accumulation rate.
