Soil collembolan is deemed as an epitome of soil invertebrate and medium-sized soil animals because of its abundance in species and hugeness in biomass.So it plays an important role and demonstrates its unique advantages over other soil animals in the assessment of heavy metal contamination of environment; This review first briefly summarizes some methodological systems and major parameters (community structures, species character, survival,growth,reproduction, metallothionein, and enzyme) used in the study of ecotoxicology and other related biomarkers in applying Collembola in ecological risk assessment of polluted soils.In the end of this review, problems existing in and prospects of the application of Collembola in the ecological risk assessment of heavy metal contamination of soils are analyzed and discussed.
