Abstract

Heavy metal pollution, such as lead (Pb), is widely found in several water bodies, impacting fish as aquatic organisms. The Amazon sailfin catfish (Pterygoplichthys pardalis) is a freshwater fish commonly found on the bottom and walls of rivers with high concentrations of heavy-metal deposits, such as the Ciliwung River. The Ciliwung River ecosystem is known to be contaminated with heavy metals, including cadmium (Cd), lead (Pb), and mercury (Hg). Based on the Government Regulation of the Republic of Indonesia No. 20 of 1990, the lead content in the Ciliwung River remains below the Threshold Limit Value (TLV). However, the high adaptability of P. pardalis to live in polluted waters increases metal accumulation within the fish's body. Heavy metals accumulate at the tissue and organ levels, such as the gills, muscles (flesh), liver, and bones. This study was conducted to calculate the absorption capacity of P. pardalis toward lead in water, as well as the mortality of P. pardalis at determined lead concentrations. The research methods included fish acclimatization, acute toxicity tests, water quality measurement, and analysis of lead content using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The results showed that higher lead concentrations led to higher mortality in P. pardalis. The highest lead absorption was observed in P2 (11.49 mg/L) with 98% absorption, followed by P3 (139.76 mg/L) with 97% absorption, and P1 (1.95 mg/L) with 96% absorption.
