The contamination of aquatic environments has been the focus of research to understand effects on ecosystems and its species. Benthic organisms are considered potential targets since sediments act as sources and sinks for environmental contaminants. This review presents information on the effects of three types of emerging contaminants: pharmaceuticals (tested concentrations between 0.1 ng/L – 250 mg/L and 0.01 ng/g – 2.5 μg/g), metal-based nanoparticles (<100 nm) (tested concentrations between 10 μg/L – 1 mg/L and 5–140 μg/g) and micro (nano)plastics (tested concentrations between 5 μg/L – 50 mg/L and 10–50 mg/kg), on the polychaete Hediste diversicolor, a key species in estuarine/coastal ecosystems. Data shows that these contaminants promote alterations in burrowing activity (lowest concentration inducing effects: 10 ng/L), neurotransmission and damage related parameters (lowest concentration inducing effects: 100 ng/L). The characteristics of this polychaete, such as regeneration capacity, make the use this species in biomedical studies involving environmental contaminants valuable.

水生环境的污染一直是了解对生态系统及其物种的影响的研究重点。底栖生物被认为是潜在的目标，因为沉积物是环境污染物的源和汇。这篇综述介绍了三种新型污染物的影响信息：药物（测试浓度在0.1 ng / L – 250 mg / L和0.01 ng / g – 2.5μg/ g之间），金属基纳米颗粒（<100 nm）（测试浓度在10μg/ L – 1 mg / L和5–140μg/ g之间）和微（纳米）塑料（测试浓度在5μg/ L – 50 mg / L和10–50 mg / kg之间）多毛Hediste杂色是河口/沿海生态系统中的关键物种。数据表明，这些污染物促进了挖洞活动（最低浓度诱导作用：10 ng / L），神经传递和损伤相关参数（最低浓度诱导作用：100 ng / L）的改变。这种多毛cha的特性（例如再生能力）使这种物种在涉及环境污染物的生物医学研究中的使用非常有价值。
