【 摘 要 】

This study aims to analyze the bioaccumulation of chromium (Chromium) contained in the gill of Oreochromis niloticus L. due to exposure to wastewater from a leather tanning industry in West Sumatra. Tilapia was exposed to the wastewater for 30 days, and Chromium concentration was measured in the gill of tilapia with Atomic Absorption Spectrophotometer (AAS). The variation of wastewater used was 1.85% and 3.69% of the LC-50 96 hour. The results showed that the BCF value was
