“…However, intensive production of tilapia in cages prevails in São Paulo State, which traditionally employs high stocking densities (>80 kg/m 3 ) and large amounts of feed to achieve high productivity in small cages (Marengoni, 2006). Sometimes this type of farming has caused undesirable consequences, such as accumulation of nutrients in the sediment (Mallasen et al, 2012), the high cost of inputs for the manufacturing of feed (Ayroza et al, 2011;Garcia et al, 2017), outbreaks of diseases and the consequent use of therapeutic products which can result in residue accumulation in the environment and in the fish (Garcia et al, 2013;Monteiro et al, 2016;Maciel et al, 2017).…”

a b s t r a c tThe accelerated and disorderly expansion of aquaculture can lead to economic, social, and environmental problems. In this sense, it is necessary to prioritize the adoption of practices that aim for sustainable production. The aims of the present study were to identify the contributions from nature and economy in the system of tilapia cage farming. In addition, emergy accounting was utilized to evaluate whether the use of periphyton as a complementary food and the reduction of storage density improve the sustainability of this production system. Three different production managements were evaluated and compared: using traditional stocking density adopted by farmers (80 kg/m 3 ) with 100% of the daily recommended feed and without substrates for periphyton (TRAD); traditional stocking density (80 kg/ m 3 ) with 50% of the daily recommended feed and with substrates for periphyton (TDS); lower density (40 kg/m 3 ) with 50% of the daily recommended feed and with substrates for periphyton (LDS). We calculated using emergy accounting the transformity (Tr), renewability (%R), emergy yield ratio (EYR), emergy investment ratio (EIR), emergy loading ratio (ELR), emergy exchange ratio (EER), and emergy sustainability index (ESI) of the distinct production managements. The results showed that tilapia cage farming is highly dependent on resources from economy, and feed is mainly responsible for this. Thus, the decrease in stocking density and feed rate, combined with the use of periphyton, improved all emergy indices evaluated. This occurred because there was a decrease in the use of resources from economy and increase in the use of renewable natural resources. The study shows through the emergy accounting that the use of periphyton to feed cultured fish combined with a reduction in artificial feed use and a decrease in the stocking density should be encouraged to promote the sustainability on tilapia cage farming.Published by Elsevier Ltd.

“…A água é, portanto, um vetor de resíduos de antibióticos no ambiente, razão de muitos estudos terem se concentrado em ambientes aquáticos e suas matrizes (THUY et al, 2013;FAO, 2016a;2016b;RAMOS, 2018;LI et al, 2018b). Resíduos de antibióticos tem sido encontrado em matrizes fluviais e costeiras, lençóis freáticos e em alimentos da aquicultura em concentrações que vão de ng a µg (L -1 ou kg -1 ) (THUY et al, 2013;CHEN et al, 2015;YAO et al, 2015;DENG et al, 2016;MONTEIRO et al, 2016;SONG et al, 2017;LI et al, 2018b;ZHANG et al, 2018 (KŰMMERER, 2009;CHEN et al, 2015;DENG et al, 2016;QUESADA et al, 2013;GBYLIK-SIKORSKA et al, 2015;RAMOS, 2018;LI et al, 2018b).…”

“…No modo on-line, o equipamento incorpora os dispositivos para extração, clean-up e eluição da amostra para a coluna analítica, numa operação sequencial e automatizada. A automação pela SPE-on line melhora o tempo de análises dispensando etapas de evaporação e reconstituição das amostras, reduz as quantias de amostras necessárias para análises, reduz os riscos de perdas e contaminação presentes nessas etapas e, se alia a química verde pela redução em consumo de solventes orgânicos(JARDIM, 2010;MONTEIRO et al, 2016;KIM et al, 2018). Para o sistema em modo on line, é necessário um bombeamento de fases móveis que intercale os momentos de carregamento da amostra na coluna de SPE e outro que realize a eluição dos analitos para a coluna analítica.…”

Considering the factors of recognized use of different antibiotics in the global shrimp farming, the productive potential of shrimps in the northeastern Brazilian region, the residue monitoring scopes of inspection agencies and the risks associated with the use of antibiotics for food safety and public health, as well as toxicity and mechanisms of development of pathogenic microbial resistance, especially in the aquatic environment, the aim of the study was to determine, by the liquid chromatography coupled to mass spectrometry with source (LC-ESI-MS/MS), the occurrence of multiclasses and multiresidues of 12 antibiotics belonging to tetracyclines, sulfonamides, fluoroquinolones and amphenicols in shrimp (Litopenaeus vannamei), water and sediments from 5 farms shrimp farms with different models of production, present in the state of Rio Grande do Norte-Brazil. Raised nurseries were selected for collection of the 3 matrices and points upstream and downstream of the nurseries, for the collection of environmental matrices destined to the study of spatial distribution of residues in the farms. Physicalchemical parameters of water quality were evaluated during sampling. On line Solidphase extraction techniques were used to LC-MS/MS for sediment, Captiva cartridges for filtration of shrimp muscle extracts and off-line solid-phase extraction to LC-MS/MS in surface water, with the samples packed in SPE cartridges prior to the transportation to the laboratory.The chromatographic methods validations were done for the parameters of selectivity, linearity, limit of detection (LOD), limit of quantification (LOQ), accuracy, precision and long-term stability of the analytes in the matrix. LOQs ranged from 0.82 (sulfadimethoxine) to 7.63 (chloramphenicol) ng mL-1 for water, 1.23 (tetracycline) at 15.99 (chloramphenicol) μg kg-1 for sediment and 1.24 (enrofloxacin) at 12.05 (sulfatiazole) μg kg-1 for shrimp. Sulfadimethoxine (23.4 ng L-1) and florfenicol (10.78 to 175.77 ng L-1) residues were the only antibiotics detected and quantified in nursery water. In sediments, oxytetracycline, enrofloxacin and norfloxacin residues were detected only upstream of the nurseries and at levels

Water contaminated by oil poses challenges to the management of water resources. Magnetic nanoparticles has been issue of different potential applications including remotion oil from water. Magnetic polystyrene-palygorskite nanocomposites were prepared by a heterogeneous phase polymerization for the removal of organic contaminants from water. The organo-Fe 3 O 4 -palygorskite nanoparticles were coated with polystyrene, forming water repellent and oil absorbing surfaces to promote the removal of oil from the surfaces of nanocomposites by applying an external magnetic field. X-ray fluorescence, X-ray diffraction, scanning electron microscopy, zeta potential and size distribution measurement, surface area determination by BET, density measurement by He pycnometry, carbon grade determination, thermogravimetric analysis, Fourier-transform infrared spectroscopy, Raman spectroscopy, and evaluation of hydrophobicity by contact angle were used to characterize the nanoparticles. The magnetic nanocomposite obtained showed excellent hydrophobicity, around 788 contact angle. In addition, oil removal capability tests were also performed, according to which the preliminary results indicated removal of approximately 98% of oil in synthetic oily water samples. The oil-water separation using this magnetic nanocomposite provides a promising alternative strategy for water treatment.
