“…Relatively low concentrations were detected in raw sewage aqueous phase for TEP (114 ± 54 ng/L), TMP (99 ± 20 ng/L), TnBP (74 ± 12 ng/L), TiBP (45 ± 18 ng/L), TDCP (23 ± 2 ng/L), TPhP (21 ± 5 ng/L), TCrP (9 ± 5 ng/L) and EHDPP (14 ± 1 ng/L). Of all the target compounds in this study, the predominance of TBEP, TCPP and TCEP were also observed in STP wastewater in most developed countries including Spain (Rodriguez et al, 2006;Quintana and Reemtsma, 2006;Garcia-Lopez et al, 2010), Germany (Rodil et al, 2005;Meyer and Bester, 2004), Austria (MartinezCarballo et al, 2007) and Sweden (Marklund et al, 2005) (Table 2). In the present study, raw sewage aqueous phase concentrations of TBEP, TCPP and TCEP were lower than those in surface water in Beijing: 10-740 ng/L TBEP, 145-1359 ng/L TCPP, and 88.4-2918 ng/L TCEP (Gao et al, 2015), which may result from the separation of rain and sewage considering that rainwash can directly bring a plenty of OPEs from soil, dust and airborne particles into the river.…”

“…Current studies mainly focused on the detection of OPEs in sewage water (Rodil et al, 2005;Garcia-Lopez et al, 2008;Martinez-Carballo et al, 2007;Ellis et al, 2007;Rodriguez et al, 2006;Quintana and Reemtsma, 2006) and sludge (Bester, 2005;Chen and Bester, 2009;Zeng et al, 2014), as well as the elimination of OPEs from sewage water (Marklund et al, 2005;Meyer and Bester, 2004). Research conducted at STPs in Germany (Meyer and Bester, 2004) and Sweden (Marklund et al, 2005) showed great removal difference for various OPEs (Table 1) in aqueous phase during sewage treatment: chlorinated alkyl OPEs showed no obvious elimination, while alkyl OPEs (TMP, TnBP, TPhP and TBEP in Table 1) showed an elimination in the range of 20-100%.…”

“…On the other hand, using SPME resulted in a richer chromatogram (Figure 1-B), while being cleaner and faster way of sample preparation and injection. Furthermore, the reproducibility and robustness of the method is well described and it is a widely adopted methodology in quality control in food science (Bianchi et al, 2007;García-Llatas et al, 2007;Plutowska and Wardencki, 2007;Romeo et al, 2007), pesticides, environmental science and in volatiles substances in general (Pacolay et al, 2006;Balakrishnan et al, 2006;Kayali et al, 2006;Luan et al 2006;Rodríguez et al, 2006;Kolb and Püttmann, 2006).…”

RESUMO: "Perfi s gerados dos voláteis obtidos de extratos de plantas através da técnica MEFS-CG-EM" O Laboratório de Química de Produtos Naturais (LQPN) possui uma coleção ex situ de pequenas quantidades de extratos obtidos de componentes da biodiversidade para fi ns de bioprospecção. Esta coleção conta atualmente com cerca de 4000 extratos de mais de 1000 espécies distintas. Os extratos são usados na identifi cação de novos compostos bioativos que possam servir para o desenvolvimento de novas drogas contra as doenças negligenciadas como leishmanioses, doença de Chagas, malária e tuberculose. Após serem submetidos aos ensaios biológicos, os extratos que apresentaram atividade precisam ser preparados em uma quantidade maior a partir de recoletas dos vegetais, para permitir o isolamento dos seus componentes ativos. Neste ponto, o desenvolvimento de metodologias padronizadas que permitam comparar a composição dos extratos recém obtidos com a dos extratos originais são importantes para confi rmação da identidade dos mesmos. Avaliou-se a metodologia de Micro-Extração em Fase Sólida, seguida de análise por Cromatografi a Gasosa e Espectrometria de Massa (MEFS-CG-EM). Foi usado o software AMDIS (Automatic Mass Spectral Deconvolution and Identifi cation System) para armazenar e comparar os perfi s gerados (fi ngerprint). Quarenta e seis amostras foram analisadas, onde foi possível inferir sobre os constituintes de cada amostra e traçar um perfi l de composição e de componentes comuns. Foram analisados nove grupos de amostras, coletadas em diferentes períodos onde se estudou as variações sazonais ocorridas entre elas. Os resultados mostraram a viabilidade do uso desta ferramenta para monitorar a composição de extratos, permitindo avaliar alterações químicas durante a estocagem, a comparação entre extratos oriundos de coletas distintas, e na ocorrência de alguns componentes em diferentes extratos. Unitermos:Cromatografi a gasosa-espectrometria de massa (CGEM), perfi l gerado, extratos vegetais, micro-extração em fase sólida (MEFS), AMDIS. ABSTRACT:The Laboratory of Chemistry of Natural Products has an ex situ collection of extracts from organisms of the biodiversity aiming at bioprospecting. Nowadays the collection has about 4000 extracts from 1000 different species. Extracts are used to identify new bioactive compounds that could be useful for developing new drugs against neglected diseases like leishmaniosis, Chagas disease, malaria and tuberculosis. After biologic assays, the bioactive extracts need to be prepared in larger quantity to allow isolation and characterization of the bioactive component. At this time, it is important to not only confi rm the bioactivity of new extract but also check if its composition is similar to the old one. It was evaluated the ability of Solid Phase Microextraction and Gas Chromatography-Mass Spectrometry analysis (SPME-GC-MS). It was used the AMDIS (Automatic Mass Spectral Deconvolution and Identifi cation System) software as tools to collect and to compare the chromatographic profi l...

“…Many of the OPEs are not chemically bonded to the final products, and thus are easily released to the aquatic environment via domestic sewage, industrial wastewater, and rainfall runoff from construction sites and pavements, as well as through the disposal of OPEs-containing materials [2,3].…”

a b s t r a c tOrganophosphate esters (OPEs) have emerged as a new class of contaminants due to their massive use as flame retardants and plasticizers. These contaminants are toxic to aquatic organisms and some of them are not biodegradable in wastewater treatment plants. This study investigated the degradation kinetics of eight typical OPEs during ozone and UV/H 2 O 2 treatments in Milli-Q water, humic acid (HA) solution, and municipal secondary effluent. The studied OPEs included three chlorinated: tris(2-chloroethyl) phosphate (TCEP), tris(chloropropyl) phosphate (TCPP) and tris(dichloropropyl) phosphate (TDCP); two aromatic: triphenyl phosphate (TPhP) and tricresyl phosphate (TCrP); and three aliphatic: tri-n-butyl phosphate (TnBP), tris(2-butoxyethyl) phosphate (TBEP), and tris(2-ethylhexyl) phosphate (TEHP). Results indicate that the degradation of target OPEs conformed to the pseudo-first-order kinetics and UV/H 2 O 2 was more effective than ozone for their elimination by comparing the overall removal efficiencies and energy consumptions. Two aromatic and two aliphatic OPEs (i.e., TPhP, TCrP, TnBP and TBEP) were effectively degraded by ozone and UV/H 2 O 2 in the test water matrices, while all chlorinated and one aliphatic OPEs (i.e., TCEP, TCPP, TDCP and TEHP) were found to be recalcitrant to oxidation. Moreover, the presence of HA significantly enhanced the degradation of reactive OPEs in ozone treatment.
