Almeida, {C M. R. 2016. Constructed wetlands for livestock wastewater treatment: Antibiotics removal and effects on CWs performance. In Phytoremediation: Management of Environmental Contaminants, Volume 4, 267 - 281. ISBN: 9783319418100. Switzerland: Springer International Publishing AG. <p>Constructed wetlands (CWs) are defined as engineered wetlands that utilize natural processes involving soil, wetland vegetation
and their associated microbial assemblages to assist the treatment of wastewaters or other polluted water sources. Although
CWs have been applied to different types of wastewaters, CWs application to livestock wastewaters is more complicated do to
the characteristics of these waters and only a few studies have reported CWs application in these cases. Livestock wastewater
can contain diverse veterinary drugs, including antibiotics, which are normally not removed in wastewater treatment plants.
Consequently, veterinary antibiotics or their active compounds can enter directly in the water system through effluent discharges,
which can lead to serious toxic effects in organisms and promote antibiotic resistance. Therefore, efficient wastewater treatments
are needed. Considering the problematic of antibiotics release in the environment, the need for methodologies to efficiently
remove these compounds from wastewater effluents, namely from livestock wastewater effluents, and the scarcity of studies
on the application of CWs to deal with this problem, authors have been developing a series of studies to evaluated CWs applicability
for livestock wastewater treatment. Studies have been assessing not only antibiotics removal but also antibiotic possible
effects on CWs performance. These studies will be presented in this chapter.</p>.

"Potential of constructed wetlands microcosms for the removal of veterinary pharmaceuticals from livestock wastewater", Bioresource Technology 134, -: 412 - 416. The aim of the present work was to evaluate, at microcosm level, the capacity of constructed wetlands (CWs) to remove veterinary
pharmaceutical compounds, from wastewater. Results indicated that CWs have potential to mitigate the release of veterinary
drugs, namely enrofloxacin (ENR, a fluoroquinolone) and tetracycline (TET, tetracyclines family). Removal efficiencies of
94% and 98% where achieved for TET and ENR, respectively, when treating pigfarm wastewater effluent doped at 100µgL drug level,
along twelve weeks. Occurrence of adsorption of the drugs to CWs substrate may be the predominant mechanism for ENR, although
for TET there are signs that degradation is also occurring. © 2013 Elsevier Ltd.

among extraction techniques", Analytical Methods 5, 22: 6503 - 65. Veterinary drugs are still poorly studied in terms of pathways, release rates and effects on the environment. So, it is necessary
to determine their levels in sewage sludge and soil/sediments affected by wastewaters. However, published methodologies deal
usually with compounds from only a few classes. In addition, there is a lack of comparisons among the different extraction
technologies used. A multi-family methodology for the simultaneous determination of minocycline, oxytetracycline, tetracycline
(tetracyclines), enrofloxacin (fluoroquinolone) and ceftiofur (cephalosporin) in sludge and sediment was pursued. Three extraction
techniques were compared, vortex agitation, ultrasonic extraction (USE) and microwave assisted extraction. Introduction of
solid-phase extraction (SPE) for sample clean-up and pre-concentration was also evaluated. The complex matrix of solid samples
posed specific problems, implying the need for individualized approaches for sediments and sludge. For sediments, USE sequential
extraction (2 cycles) with methanol-acetone was chosen. LODs, when using SPE, ranged from 0.009 to 0.02 µg g. For sludge,
samples were sequentially extracted three times by USE with methanol-formic acid. The SPE allowed lowering the limits 10 times
ranging from 0.08 to 0.3 µg g for LODs. The method yielded good selectivity and acceptable recovery results. The present methodology
resulted in suitable multi-family approaches, less common than the majority of similar processes published. © 2013 The Royal

"Can salt marsh plants influence levels and distribution of DDTs in estuarine areas?", Estuarine, Coastal and Shelf Science 93, 4: 415 - 419. Sediments are depositories of toxic substances such as organochlorine pesticides and there is a global need for their removal
in contaminated environments. Studies that combine contaminated sediments and phytoremediation are relatively recent and their
number has been increasing. This work aimed to investigate whether salt marsh plants (sea club-rush Scirpus maritimus, sea
rush Juncus maritimus and sea purslane Halimione portulacoides) can favor DDT and metabolites remediation in estuarine environment.
For this purpose the levels of DDT, DDE and DDD were compared in vegetated and non-vegetated sediments from an estuary in
the North of Portugal (in-situ study) and from another in the South of Portugal (ex-situ study). Results obtained both in
the in-situ study, involving S. maritimus and J. maritimus, and in the ex-situ study, involving H. portulacoides, indicated
that these plants did not have a significant role in DDTs removal and/or degradation. Therefore, it seems that the tested
plants cannot influence levels and distribution of DDTs in estuarine areas. © 2011 Elsevier Ltd.

Morais, De. 2011. "A headspace SPME-GC-ECD method suitable for determination of chlorophenols in water samples", Analytical and Bioanalytical Chemistry 399, 7: 2531 - 25. A headspace solid phase microextraction coupled to gas chromatography with electron capture detector (HS-SPME-GC-ECD) method
was optimized for the determination of seven chlorophenols (CPs) with different levels of chlorination. This is the first
time that HS-SPME-GC-ECD with acetylation of the analytes is used for the simultaneous determination of CPs in water samples.
The influence of fibre type, derivatization conditions, salt addition, temperature and time of extraction and temperature
of desorption was checked. Possible sources of contamination and analyte losses were considered. The best results were obtained
with the polydimethylsiloxane/divinylbenzene fibre, derivatization by acetylation using 100 µL of acetic anhydride and 0.1
g of anhydrous sodium carbonate per 10 mL of sample, salt addition of 100 g L sodium chloride, extraction
at 70 °C for 60 min and desorption in the GC injector at 260 °C for 6 min. The limits of detection (LOD) for monochlorophenols
were 12 and 122 ng L for 2-chlorophenol and 4-chlorophenol, respectively. For polychlorinated CPs,
the LODs were lower than 6 ng L , values similar to the existing methods that use SPME with derivatization
for CPs determination in water samples. The method is suitable for the determination of CPs in most environmental aqueous
samples. Repeatability and reproducibility were less than 16.8% and 11.7%, respectively. The optimized method was successfully
applied for the analysis of waters with complex matrices such as river and estuarine water samples. © 2011 Springer-Verlag.

all over the Portuguese coastal sediments were scarce. Therefore, in 2007-2008 12 OCPs were surveyed in surface sediments
from 11 coastal sites (estuarine or lagoonal) covering north, centre and south areas of Portugal. Analyzes were performed
using a previously validated method, involving pre-extraction of OCPs from sediments assisted by microwave and headspace solid-phase
microextraction followed by gas chromatography with electron capture detection for quantification and mass spectrometry for
OCPs identification. Measurable levels (0.08-26 ng g ) of a-hexachlorocyclohexane (a -HCH), ¿-hexachlorocyclohexane
(lindane), aldrin, dieldrin, endrin, 4,4'-DDT, 4,4'-DDD, 4,4'-DDE, heptachlor, heptachlor epoxide, endosulfan I and methoxychlor
were observed in all cases. In few cases, the found levels denote the probability of occurrence of adverse biological effects.

This work aimed to report present levels (2007-2008 sampling) of tri- (TBT), di- (DBT), and monobutyltin (MBT) in surface
sediments from 11 Portuguese coastal sites and discuss the evolution of BTs contamination in the last two decades. All the
samples revealed quantifiable values of TBT, DBT, and MBT with total butyltin concentrations between 1 and 565 ng/g (of Sn
in dry sediment). Maximum level of TBT, 66 ng/g, was observed in Sado estuary, at Lisnave site, in the proximity of a big
shipyard. MBT decreased site by site by the same order as DBT and TBT did, but its concentrations were much higher in many
cases, denoting that TBT contamination was much higher in the past. A comparison with the available previous data confirmed
a marked decrease of TBT contamination all over the last years, indicating that the main sources of TBT in Portuguese coastwise
stopped effectively. © 2008 Springer Science+Business Media B.V.

Carvalho, Pedro; Rodrigues, P.N.R.; Alves, F.; Evangelista, R.; Basto, M.C.P.; Vasconcelos, M.T.S.D.. 2008. "An expeditious method for the determination of organochlorine pesticides residues in estuarine sediments using microwave assisted
pre-extraction and automated headspace solid-phase microextraction coupled to gas chromatography-mass spectrometry", Talanta 76, 5: 1124 - 11. Determination of organochlorine pesticides (OCPs) in sediments implicates extraction of these compounds from the matrix, which
is difficult owing to strong interaction among OCPs and different constituents of the sediments, particularly organic content.
The method here described is a combination of microwave assisted extraction (MAE), headspace solid-phase microextraction (HS-SPME)
and gas chromatography-mass spectrometry (GC-MS), acting in selected-ion storage mode, or GC-electron capture detector (ECD,
for routine analysis). Methanol was used as extracting solvent and aliquots of the MAE extracts (after inclusion of a step
for sulfur elimination when required) were used to prepare aqueous solutions for HS-SPME. A complete automation of the SPME
procedure increases the sample throughput, including standard addition for calibration purpose. The procedure has the advantage
of exclude additional clean-up steps and pre-concentration before SPME. Application to reference sediments of different characteristics
revealed absence of significant interferences from the matrix for a-lindane, ¿-lindane, aldrin, dieldrin, endrin, 4,4'-DDT,
4,4'-DDD, 4,4'-DDE, heptachlor, heptachlor epoxide and good sensitivity. Detection limits ranged from 0.005 to 0.11 ng of
OCP per gram of dried sediment using GC-MS and from 0.01 to 0.26 ng g using GC-ECD. The linear response ranges embraced 5-6
orders of magnitude (up to 1000 ng g) in GC-MS, being narrower for GC-ECD. The method was successfully applied to sandy and
muddy sediments from Portuguese rivers estuaries, enabling quantification of seven OCPs. The method resulted effective, relatively
simple and fast, being suitable for routine monitoring of residues of OCPs from sediments of different grain size and organic
matter content, which influence concentration, mobility and availability of contaminants. © 2008 Elsevier B.V. All rights

"Application of SPME to the determination of alkylphenols and bisphenol A in cyanobacteria culture media", Analytical and Bioanalytical Chemistry 391, 1: 425 - 432. In order to survey the influence of estrogenic compounds on cyanobacteria, solid-phase microextraction (SPME) with a carbowax-divinylbenzene
fibre was used for the determination of tert-octylphenol (tert-OP), n-nonylphenol (n-NP), technical nonylphenol (tech-NP)
and bisphenol A (BPA) in cyanobacteria culture media by gas chromatography with flame ionization detection. Determinations
were carried out without derivatization in deionized water and filtered culture media. A comparison between f2 and Fraquil
culture media was performed, which showed that only f2 allowed quantitative recoveries. Headspace SPME with salting out, requiring
only 10 mL of sample, was suitable for tert-OP, n-NP, and tech-NP determination with limits of detection (LOD) of .

Carvalho, Pedro; Pinto, L.F.; Basto, M.C.P.; Vasconcelos, M.T.S.D.. 2007. "Headspace solid-phase micro-extraction and gas chromatography-ion trap tandem mass spectrometry method for butyltin analysis
in sediments: Optimization and validation", Microchemical Journal 87, 2: 147 - 153. In this work, headspace solid-phase micro-extraction (SPME) combined with gas chromatography-mass spectrometry (GC-MS) method
for analysis of butyltin compounds in sediment samples was upgraded by the introduction of tandem mass spectrometry (MS/MS).
Optimization and validation of this method based on an one step procedure, tetraethylborate in situ ethylation with simultaneous
extraction by headspace SPME, combined with tandem mass spectrometry is described. A simple leaching/extraction step of mono-(M),
di-(D) and tri-(T) butyltin (BT) compounds from the sediment is required as sample pre-treatment. The combination of the two
techniques headspace SPME and MS/MS, led to very little matrix interference which permitted to attain limits of detection
three or more orders of magnitude lower than those attained in previous methods: 0.3 pg g for MBT, 1 pg g for DBT and 0.4 pg
g for TBT. Linear response range was from 0.02-1260 ng g for MBT, 0.07-1568 ng g for DBT and 0.04-2146 ng g for TBT and RSD
<15% was also obtained. The method was efficiently applied to a real sample sediment from Sado River estuary in Portugal,
revealing the existence of BTs pollution, as the TBT level of 189 ± 15 ng g was much higher than the maximum established as
provisional ecotoxicological assessment criteria. © 2007 Elsevier B.V. All rights reserved.

Vargas, Carlos A. R; Arias, Carlos A; Carvalho, Pedro; Brix, Hans. Removal Kinetics of Organic Matter and Nitrogen Using Microbial Electrochemical Based - Constructed Wetlands (iMETland),2016 (Poster). In recent years the combination of Constructed Wetlands and Microbial Fuel Cell (MFC), has led to an innovative set- up for
wastewater treatment and energy harvesting, relaying on electrodes and external circuits (CW – MFC).<br/>Based on this approach,
a new concept is being developed to create the Microbial Electrochemical-based Constructed Wetland (iMETland). In this system
electro- active bacteria – EAB (e.g. Geobacter sp., Shewanella spp) are stimulated to release and transfer electrons to an
electro-conductive material that act as unlimited electron acceptor, maximizing the substrate consumption.<br/>The iMETland
technology is still in development and therefore uncertainties still exist regarding the dynamics in the removal of pollutants,
as well as in its performance along time. To elucidate these uncertainties, a benchmark study is being conducted to characterize
the processes and interactions n the removal of organic matter, nutrients and pollutants of interest in the systems.
