Factorial analysis of the trihalomethane formation in the reaction of colloidal...
Platikanov, Stefan; Tauler, Roma; Rodrigues, Pedro M.S.M.; Antunes, Maria Cristina G.; Pereira, Dilson; Esteves da Silva, Joaquim C. G.Background, aim, and scope This study focuses on the factors that affect trihalomethane (THMs) formation when dissolved organic matter (DOM) fractions (colloidal, hydrophobic, and transphilic fractions) in aqueous solutions were disinfected with chlorine. Materials and methods DOM fractions were isolated and fractionated from filtered lake water and were characterized by elemental analysis. The investigation in...
Two-generational effects of contaminants in Daphnia magna : Effects of offsprin...
Campos, Bruno; Jordão, Rita; Rivetti, Claudia; Lemos, Marco; Soares, Amadeu; Tauler, Roma; Barata, CarlosThe authors set up a protocol to perform a 2-generational ring test using the existing guidelines for the Daphnia magna reproduction test. It is well known in ecology that size and quality of offspring vary across the first clutches in D. magna and that certain chemicals affect offspring quality. Therefore, the origin of the second generation is an important factor to consider. Two-generational effects across f...
