Abstract As a main roup of animals in th e soil th e earthw orms play im portant functions in ecosystem They contribute to th e complex processes of decomposition, to the de radation of plant debris and to the mineralization of or anic materials. They mix the soil, improve soil aeration, draina e and moisture holdin capacity and help to . : , maintain soil structure These functions link up with th eir biomass and ecolo ical cate ories epi eic endo eic and . , anecic By exploitin these functions w e can consciously use suitable earthw orms for the purpose of environm ental protection. They are ood bioindicators of soil environm ent , for w hich the ecotoxicolo ical test by usin earthworm s both in laboratory and in field are set up for the evaluation of ch emical contaminants in the soil. They . can considerably accelerate the decomposition of or anic materials by the syner y w ith microor anism A new technolo y of vermicomposition is developed for the t reatment of or anic waste. It seems that another new technolo y by usin earthw orms for the treatment of urban sew a e, vermifilt ration, is developin , which will have a wider application.
