Micropollutants are defined as contaminants found in trace concentrations water bodies that persistent and bioactive, meaning they not completely biodegradable cannot be removed by conventional treatment methods. Because of these aspects, their detection removal pose a challenge to the scientific community. Among them endocrine disruptors, drugs, agricultural chemicals, personal grooming products, industrial additives others. These micropollutants cause for global concern, because presence...
Abstract Removal of an endocrine disrupting compound, Bisphenol A (BPA), from water was investigated using two treatment processes, UV/H2O2 advanced oxidation (AOP) and reverse osmosis (membrane separation). Furthermore, changes in estrogenic activity vitro yeast estrogen screen assay as well the adsorption BPA by membrane surface were evaluated. The best performance obtained highest established values all parameters, reaching 48% removal. Within conditions AOP, when lower doses UV used, a...
The aim of this study was to analyze the growth rings and evaluate effect urban environment on Terminalia catappa L. under intense industrial activity. At least two wood samples were obtained from each tree with an increment borer. regions Volta Redonda (Northwest Southeast regions) Resende (used as control) established for collection. dendrochronological potential T. indicated sensitivity precipitation temperature in a more exposed steel pollution area because there differences when...
Fouling mechanisms are mainly caused by the deposition of organic compounds that reduce removal efficiency on reverse osmosis (RO) membranes. It can be described mathematical models. The aim this study was to evaluate membrane fouling and rejection when aqueous solutions containing 17α-ethinylestradiol (EE2) in different concentrations permeated at 5 10 bar a bench-scale dead-end RO system. Adsorption tests were performed mechanism assessed Hermia's model for EE2 typically found environment...
Bisphenol-A (BPA) and 17α-ethinylestradiol (EE2) are considered endocrine disrupting compounds (EDC) they may be harmful to the normal functioning of systems humans animals. Moreover, presence these in superficial groundwater represent serious risks, even low concentrations like ng·L-1. The objectives this study were remove BPA EE2 from solutions containing a mixture ultrapure water at through reverse osmosis (RO) membrane combined with UV/H2O2 process. Furthermore, assess estrogenic...
O presente trabalho teve como objetivo comparar a taxa de infiltração água sob diferentes condições uso do solo, fim obter valores referência e avaliar o potencial no provimento serviços ecossistêmicos relacionados à produção água. Sendo assim, foram consideradas três classes cobertura solo: sistema agroflorestal (SAF) em estágio avançado, pastagem floresta inicial regeneração. As áreas estudo estão localizadas na região sudeste Brasil, bioma Mata Atlântica, estado Rio Janeiro. Para obtenção...
Introdução: O setor florestal foi considerado de “vocação masculina”, devido à relação com atividades desenvolvidas em campo. No entanto, cursos engenharia seguem a tendência da educação superior, aumento presença feminina. Ações para divulgação mulheres diferentes áreas das ciências florestais e o reconhecimento pioneiras, contribuem igualdade gênero diminuição situações discriminação preconceito. Objetivo: objetivo do projeto extensão “Mulheres nas Ciências Florestais” UFRRJ, realizar...
