Abstract Kraft mill effluents were biologically treated in an aerated lagoon (AL) (3.4 L) to evaluate the behavior of aromatic compounds by UV‐vis spectroscopy. Under aerobic conditions, biological oxygen demand (BOD 5 ) removal was between 84% and 95%, whereas soluble chemical (COD s ranged 40% 60%. A slight increase observed VIS 436 /COD relationship (0.101–0.110), indicating that color reduction less than total organic matter expressed COD . Additionally, low values UV 254 /UV 280...
A Moving Bed Bioreactor (MBBR) was operated at three different hydraulic retention times for a period of 414 days. The fate the extractive compounds and estrogenic activity Pinus radiata kraft mill effluents were evaluated using Yeast Estrogen Screen (YES) gas chromatography - mass spectrometry (GC-MS) detection. Results show that MBBR reactor is able to remove between 80-83% present in influent, where values effluent's ranged 0.123-0.411 ng L(-1), expressed as equivalent (EEqs)...
Aryl Hydrocarbon Receptor (AhR) ligands also known as dioxin-like compounds, constitute a substantial part of the total toxicity from many pollution sources, including pulp mill effluents. The aim this article was to evaluate activity in different kraft effluents by combination yeast bioassays and gas chromatography-mass spectrometry (GC-MS) chemical analysis. study includes three sources raw material: Pinus radiata, Eucalyptus globulus both (50% each). Recombinant Yeast Assay (RYA) showed...
Objective: To find any role of optimism and/or resilience mediating emotional distress in infertility.Method: We performed a literature search for 2000-2017 PubMed, PsycINFO and Elsevier, original articles reviews, using keywords "resilience," "infertility," "optimism," "LOT-R," "in vitro fertilization," "assisted reproductive technology."Additional references were collected from located thereby.Results: The evidence reveals growing trend promoting people´s positive health assets indicates...
The aim of this work was to know the differential composition dissolved fraction a glyphosate-based herbicide (GBH), commercialized as GLIFOPAC, when reaches different aquatic environments and its ecotoxicological effects on crustaceans species living in them. Daphnia magna, Tisbe longicornis, Emerita analoga were exposed glyphosate called GLIFOPAC (480 g L−1 active ingredient or a.i.) at concentrations between 0.5 4.8 a.i. L−1. Acute toxicity D. magna (48 h-LC50), E. T. longicornis (96...
The Biobío River basin (central south of Chile) is highly impacted by a variety anthropogenic activities such as pulp mills subjected to different treatment processes.The cellulose production has notoriously increased in the Region last years reaching more that 80% country production.This industrial activity concentrates its using raw material fast growing vegetal species like radiata pine (Pinus radiata) and eucaliptus (Eucalyptus globulus).Environmental effects this massive widely known...
Stigmasterol is a phytosterol contained in Kraft mill effluent that able to increase over 100% after aerobic biological treatment. This compound can act as an endocrine disrupter its structure similar of cholesterol. The aim this study was evaluate the removal stigmasterol from effluents treated by moving bed biofilm reactor (MBBR) with steroidal metabolite detection. MBBR operated for 145 days, hydraulic retention time 2 days. and metabolites were detected gas chromatography flame...
Kraft mill effluents treated by activated sludge show a reduction in acute toxicity. However, their discharges produce hormonal effects an aquatic ecosystem, due to the sterols metabolites as androstenedione contained effluents. Daphnids bioassays are powerful approach for determining there relative sensitivities depending on species. The main objective of this study is determine sensitivity D. magna and obtusa when exposed kraft effluents, diethylstilboestrol (DES), (AED). were tested using...
Background: Infertility generates high levels of stress to women. The aim was explore optimism and resilience among women undergoing assisted reproductive technology (ART). Method: Participants were recruited in a private fertility clinic. sample consisted 229 under medical treatment for who completed the following self-report instruments: sociodemographic clinical questionnaire, Resilience Scale (RS), Life Orientation Test (LOT-R), Perceived Stress (PSS), STAI State Trait. Results: Our data...
The objective of this study is to evaluate the stability activated sludge (AS) in treatment kraft pulp mill effluent exposed black liquor shock, as well effect its exposure on morphology Daphnia magna and DNA damage through mutagenicity genotoxicity response Salmonella typhimurium. To end, we applied doses 2-, 4-, 10-, 30-mL liquor/L influent—shock 1 (S1), shock 2 (S2), 3 (S3), 4 (S4), respectively—to effluent. system was checked by analyzing heterotrophic biomass activity discharge quality,...
