| The fourth instar larvae of C. riparius were treated with potential endocrine disruption chemicals (EDCs) such as bisphenol A (BPA) and 4-nonylphenol and the effects of morphological abnormalities were observed. The deformities of the mentum following exposure to EDCs showed the smooth tooth, the loss of tooth and deformed tooth. The incidence rates of the mentum deformity were associated with chemicals: BPA $31{sim}90%$, and 4-nonlyphenol was $40{sim}80%$. As the concentration of BPA increased, the incidence of deformed mentum was dose dependent. While the incidences of deformed mentum following exposure to 4-nonlyphenol was not associated with their concentrations. The deformed MLT observed smooth or round tooth and the deformity of LT showed loss of one or more than tooth. Also, the MIX type was usually smooth or loss tooth. The abundance of deformity type for the mentum showed MIX (MLT+LT) > LT (lateral teeth) > MLT (median lateral teeth). |
