Effects on earthworms in the contaminated floodplain area the Biesbosch, the Netherlands, were determined at different levels of organization using a combination of field and laboratory tests. The species Lumbricus rubellus, collected from different polluted sites in the Biesbosch, showed reduced values for the biomarker neutral red retention time (NRRT), mainly explained by high metal concentrations in the soil and the resulting high internal copper concentrations in the earthworms. Organic pollutant levels in earthworms were low and did not explain reduced NRRTs. Earthworm abundance and biomass were not correlated with pollutant levels in the soil. Litterbag decomposition and bait-lamina feeding activity, measures of the functional role of earthworms, were not affected by metal pollution and did not show any correlation with metal concentrations in soil or earthworms nor with NRRT. Effects at the biochemical level therefore did not result in a reduced functioning of earthworm communities.
利用现场和实验室测试相结合的方法，在荷兰比斯博斯被污染的洪泛区，针对不同组织水平测定了对蚯蚓的影响。从比斯博斯不同污染地点采集的赤子爱胜蚓，其生物标志物中性红保留时间（NRRT）值降低，主要原因是土壤中金属浓度高，导致蚯蚓体内铜浓度高。蚯蚓体内的有机污染物水平较低，无法解释NRRT降低的原因。蚯蚓的丰度和生物量与土壤中的污染物水平无关。作为蚯蚓功能作用衡量指标的垃圾袋分解和饵料薄片摄食活动，不受金属污染影响，与土壤或蚯蚓中的金属浓度以及NRRT均无相关性。因此，生化水平的影响并未导致蚯蚓群落功能降低。
