Various methods are available for monitoring pollution levels in surface water and sediments, including using organisms as bioindicators. Segara Anakan Lagoon is an estuarine ecosystem that could be affected by contaminants transported by rivers. Pollution sources include pesticides and fertilizers from upstream agricultural areas, domestic waste, and shipping traffic. Macrozoobenthos are among the organisms commonly used as bioindicators of environmental pollution. Macrozoobenthos live at the bottom of the water column, and as deposit feeders, they lend themselves to use as bioindicators. The structure of the macrozoobenthos community in Segara Anakan has changed, as evidenced by the diversity and abundance of benthic species. Furthermore, environmental pollution parameters, such as heavy metal concentrations in water and sediments, are relatively high in the lagoon. Concentrations of Hg, Pb, Cd, and Cr varied among collection sites, with average concentrations of 0.04, 4.4, 1.2, and 1.4 ppm, respectively. In general, the abundance of macrozoobenthos was low at collection stations with high heavy metal concentrations, demonstrating that heavy metal pollution has occurred in Segara Anakan. Correlation tests between macrozoobenthos and heavy metal concentrations in water and sediments yielded r-values of > 0.8225 and 0.7473, respectively.

有多种方法可用于监测地表水和沉积物中的污染水平，包括使用生物体作为生物指标。Segara Anakan 泻湖是一个河口生态系统，可能会受到河流输送的污染物的影响。污染源包括上游农业区的农药和化肥、生活垃圾和航运。大型底栖动物是通常用作环境污染生物指标的生物之一。大型底栖动物生活在水柱的底部，作为沉积物的饲养者，它们可以用作生物指示物。Segara Anakan 大型底栖动物群落的结构发生了变化，底栖物种的多样性和丰富性就是明证。此外，环境污染参数，例如水和沉积物中的重金属浓度，在泻湖中相对较高。Hg、Pb、Cd 和 Cr 的浓度因收集点而异，平均浓度分别为 0.04、4.4、1.2 和 1.4 ppm。总体而言，在重金属浓度较高的收集站，大型底栖动物的丰度较低，这表明 Segara Anakan 已经发生了重金属污染。大型底栖动物与水和沉积物中重金属浓度的相关性测试分别得出 r 值 > 0.8225 和 0.7473。表明 Segara Anakan 已发生重金属污染。大型底栖动物与水和沉积物中重金属浓度的相关性测试分别得出 r 值 > 0.8225 和 0.7473。表明 Segara Anakan 已发生重金属污染。大型底栖动物与水和沉积物中重金属浓度的相关性测试分别得出 r 值 > 0.8225 和 0.7473。
