Abstract:
:A newly proposed three-dimensional model for the effects of heavy metals on the growth of batch cultures of algae that allows the estimation of the no detected toxic effect concentration (NDEC) is presented. Two batch assays with exposure to copper were investigated in situ. As an endpoint in the in situ studies of ecotoxicology, the carrying capacity, a parameter of the logistic growth model, possesses higher sensitivity and reliability than the routine ecotoxicological endpoints in terms of the analysis based on the theoretical arguments and experimental results. Using the carrying capacity (B(f)) as the ecotoxicological endpoint, the NDEC from the proposed model is compared to the NOEC and EC(05) on the basis of field derived data. The results indicate that the NDEC is a promising possible alternative parameter to the NOEC.
