Journal ArticleDOI
Lethal effects of abamectin on the aquatic organisms Daphnia similis, Chironomus xanthus and Danio rerio.
Andréa Novelli,Bruna Horvath Vieira,Daniela Cordeiro,Luciana Teresa Dias Cappelini,Eny Maria Vieira,Evaldo Luiz Gaeta Espíndola +5 more
TL;DR: The toxicity of abamectin on daphnids, insects and fish was found to be highly toxic, with an EC(50) 48 h for Daphnia similis of 5.1 ng L(-1), LC(50).
Journal ArticleDOI
Ammonia removal from landfill leachate by air stripping and absorption
TL;DR: An old landfill leachate was pre-treated in a pilot-scale aerated packed tower operated in batch mode for total ammoniacal nitrogen (TAN) removal and the effectiveness of the neutralization of ammonia with deionized water was 75%.
Journal ArticleDOI
Co-treatment of landfill leachate and domestic wastewater using a submerged aerobic biofilter.
TL;DR: This study used a pilot-scale submerged aerobic biofilter (SAB) to evaluate the co-treatment of domestic wastewater and landfill leachate that was pre-treated by air stripping and indicated that the hardly biodegradable organic matter in leachates was removed by partial degradation.
Journal ArticleDOI
Occurrence of PPCPs in a Brazilian water reservoir and their removal efficiency by ecological filtration.
Caroline Moço Erba Pompei,Luiza C. Campos,Bianca Ferreira da Silva,José Carlos Fogo,Eny Maria Vieira +4 more
TL;DR: Results of this investigation show that ecological filtration was an effective process to remove 2 μg L-1 of the selected PPCPs, and demonstrated that the filters were resilient to individual compounds and to their mixtures.
Journal ArticleDOI
Unexpected toxicity decrease during photoelectrochemical degradation of atrazine with NaCl
Geoffroy Roger Pointer Malpass,Douglas Waychi Miwa,Ricardo L. R. Santos,Eny Maria Vieira,Artur de Jesus Motheo +4 more
TL;DR: In this article, the effects of the degradation method, electrochemical and electrochemical photo-assisted, and of the supporting electrolyte, NaCl and Na2SO4, on the residual toxicity of treated atrazine solutions were studied.
