ÖZET
Toprak solucanları, çevresel kirliliğin kontrolünde indikator organizma olarak kullanılmaktadır. Ayrıca, besin siklusunun düzenlenmesinde anahtar organizmalardır. Toprak ekosistemlerindeki bir başka önemi, organik maddenin bağlanması ve ayrıştırılmasının devamını sağlamaktır. Toprağın organik maddesi ise toprak mikroflorasına enerji kaynağı olmasının yanında toprak yapısının oluşumunu da desteklemektedir.

THE ECOTOXICOLOGICAL ASSESMENT OF EARTHWORMS
ABSTRACT
Earthworms are used for control of environmental pollution as a indicator organisms. Also they are keystone soil organism in regulating nutrient cycling. One of the other important role in soil ecosystems, they contribute to organic matter incorporation and decomposition. Soil organic matter has a source of energy for soil microflora and supports formation of soil structure.
Key Words: Earthworm, ecotoxicity, contaminant, microorganism.
