ABSTRACT
The midge (Chironomus riparius), an aquatic invertebrate, was exposed to di-2-ethylhexyl phthalate (DEHP) to evaluate the effects on reproductive processes via sediment toxicity. The test endpoints included emergence, sex ratio, fecundity and viability of F1 offspring egg ropes. After exposures of C. riparius to DEHP in this study, a significant result was observed only in the viability test of F1 egg ropes. That is, hatching rates of F1 egg ropes from DEHP exposed adults were decreased significantly. This result provides the evidence that DEHP could lead abnormal egg ropes development by DEHP exposure during larval period. This means that DEHP could effect to Chironomus population density through reduced F1 offspring.
