The lead level at each sampling station has not exceeded the Indonesian National Standards threshold of 0.3 ppm for and even at the very minimum level, it was not classified as polluted by lead metal. The relationship between water quality and fish size on the bioaccumulation of lead metal was found at 65.89%, pH 53.09%, and temperature 9.08%.
