2020 - VARCA, JUSTINE P.R.O.; MARTINS, ELAINE A.J.; VARCA, GUSTAVO H.C.; ROMANO, RENATO L.; LEBRE, DANIEL T.; LAINETTI, PAULO E.O.; BUSTILLOS, JOSE O.V.
Technological advances have promoted improvements in several science fields, especially related to environmental and analytical areas with the improvement of detection and development of environmentally friendly extraction techniques. This study applied Quick, Easy, Cheap, Effective, Rugged and Safe method (QuEChERS) for soil extraction and assessed its performance through a validation study using samples from the soil of a contaminated area in Caieiras, SP, Brazil. Nine organochlorine pesticides, including the isomers alpha, beta, gamma and delta- hexachlorocyclohexane; cis- and trans-heptachlor epoxide; cis- and trans-chlordane and heptachlor were analyzed by gas chromatography coupled to electron capture detector. The method was validated according to ISO 5725-4 (2020), EURACHEM (2014) and DOQ-CGCRE-008 (2016). The limits of detection and quantification of the method for the nine organochlorines were α-HCH (1.2 and 12.6 µg kg−1), β-HCH (1.7 and 12.0 µg kg−1), γ-HCH (1.5 and 11.6 µg kg−1), δ-HCH (0.8 and 11.6 µg kg−1), heptachlor (1.0 and 10.8 µg kg−1), cis-heptachlor epoxide (0.9 and 11.5 µg kg−1), trans-heptachlor epoxide (0.9 and 11.5 µg kg−1), cis-chlordane (0.4 and 7.9 µg kg−1) and trans-chlordane (0.5 and 10.9 µg kg−1), respectively, and all of them were within the maximum limits recommended by the EPA for the compounds α-HCH (86.0 and 360.0 µg kg−1), β-HCH (300.0 and 1.3 × 103 µg kg−1), γ-HCH (570.0 and 2.5 × 103 µg kg−1), δ-HCH (not defined), heptachlor (130.0 and 630.0 µg kg−1), cis-/trans-heptachlor epoxide (7.0 and 330.0 µg kg−1), cis-/trans-chlordane (1.77 × 103 and 7.7 × 103 µg kg−1) in residential and industrial soil, respectively. Recovery results were between 65% and 105% for almost all compounds, which is an optimum result for multi-residue analytical methods, considering the complexity of the matrix used in the study. Caieiras presented contamination levels of α-HCH in the range of 2.0 to 66.0 µg g−1, which was higher than the limits established by EPA, corresponding to 0.077 µg g−1 for residential soil and 0.27 µg g−1 for industrial soil. According to the validation study, the analytical method proposed was reliable for organochlorine quantification, and the QuEChERS was considered efficient for organochlorine extraction from soil.

2019 - MAYNARD, ISABELLA F.N.; CAVALCANTI, ELIANE B.; SILVA, LARISSA L. da; MARTINS, ELAINE A.J.; PIRES, MARIA A.F.; BARROS, MARCELO L. de; CARDOSO, ENI; MARQUES, MARIA N.
Several chemical substances known as micropollutants are used in daily activities, and they pose risks to both human health and the environment. Some of these substances disrupt the endocrine system in addition to being responsible for major public health issues and for endangering some aquatic species. The aim of this research is to investigate the frequency of endocrine disruptors and anthropogenic activity markers in a Water Supply System (SAA) in Sergipe State, Brazil. Twenty-two water samples were collected from five SAA points from 2016 to 2017. They were prepared through solid phase extraction and analyzed in a gas chromatographer coupled to a mass spectrometer. In total, 13 compounds (diethyl phthalate, dibutyl phthalate, nonylphenol, pentachlorophenol, bisphenol A, androstane, estrone, estradiol, 17 a-ethinyl estradiol, progesterone, coprostanol, cholesterol and caffeine) that are endocrine disruptors and antrophic activity markers were herein assessed – both in raw (underground and surface) and treated water (distribution system and reservoir) samples. Based on our results, 50% of the samples contained caffeine; 45.5%, cholesterol; 31.81%, diethyl phthalate; 31.81%, dibutyl phthalate; 18.18%, bisphenol A; and 4.54%, estradiol. Therefore, it is important to create and implement public policies focused on public health and on assuring the safety of aquatic ecosystems.

2017 - SHIHOMATSU, H.M.; MARTINS, E.A.J.; COTRIM, M.E.B.; LEBRE, D.T.; ORTIZ, N.; PIRES, M.A.F.
The pharmaceutical compounds were analyzed in 14 sampling sites and pointed out the pollution sources related to raw sewage input and urban drainage discharge. Five medicine compounds, one illicit drug, and its metabolite were the higher measured content using analytical improvements tailored to identify and quantify organic compounds in low water content. The use of SPE cartridges followed by liquid chromatography with tandem mass spectrometry (LC-ESI-MS/MS) points out the Guavirutuba tributary as the primary water pollution source with higher concentrations in 2011 for pharmaceuticals, cocaine, and benzoylecgonine (metabolite) in the range of 6.7 ± 0.9 ng L−1 to 27.386 ± 142 ng L−1. The Jaceguay stream also located in Guarapiranga was the most preserved area and provided analytical values correspondent which lowered contamination content. Such concentrations mean a possible and feasible water restoration target. The most common compounds (above 90% samples) were: caffeine, atenolol, carbamazepine, cocaine, and benzoylecgonine. The integrated risk index for aquatic chemical pollution (IRICAP) confirms the higher contamination near Guavirutuba stream and the lower near the Jaceguay stream. Published results of cocaine and benzoylecgonine content in Guarapiranga basin corroborated with the analytical results.

Brazil has four research reactors in operation, all old and low power. The IEA-R1 reactor of IPEN/CNEN-SP has only limited radioisotope production capacity, materials irradiation, and neutron beam utilization. This reactor has been operating for fifty-nine years and has prospects of operation for a maximum period of ten years. It is necessary to implement a new reactor, which will support nuclear activities, and the national strategic objectives related to technological development in the areas of energy and defense; scientific and technological development; training of human resources and the growing production of radioisotopes for medical application. The Brazilian Multipurpose Reactor (RMB) will be a nuclear reactor for research and will be built in the state of São Paulo, in the municipality of Iperó. Its construction may involve the release of effluents into the environment. With monitoring before, during and after construction, it will be possible to verify if the construction itself will harm the environment. Several organics compounds are released daily in water bodies collaborating for environmental imbalance. Many of them have carcinogenic and mutagenic properties, receiving more attention by the scientific community. Most of the organic compounds are not included in environmental legislation and many of them present high toxicity, especially those classified as endocrine disrupters, as some Polycyclic Aromatic Hydrocarbons (PAHs). Only seven of the thirteen PAHs studied in this project are contemplated in Brazilian legislation, and just one is contained in international legislation. The PAHs studied in this work present, considered hazardous chemical compounds due to their toxicity, persistence in the environment, their bioaccumulative potential and their tendency to biomagnify. For the determination of the PAHs, the samples were concentrated by solid phase extraction (SPE) followed by quantification by High Performance Liquid Chromatography (HPLC). It was possible verify values of some PAHs below threshold limit 0.05 μg L-1 in the water bodies that cross the RMB area.

RMB will be a nuclear reactor for research and production of radioisotopes. Its applications extend to agriculture, industry and the environment. With the changes that will occur in the study area by its construction, the flow of vehicles will increase. It is known that one of the largest anthropogenic sources of PAHs is from the burning of fossil fuels and biomass. The aim of this research was to identify and quantify 14 of the 16 majorities PAHs in the sediment samples at RMB installations area in a period before the enterprise construction, June 2017, using the methodology developed and validated by Brito, 2009. It was observed individual concentrations from 0.05 to 1.11 μg g-1 in this first evaluation indicating that, although were found some PAHs concentrations above the established values by CONAMA and CETESB, this area still remains preserved. Pyrene was the compound that had the highest concentrations at different collecting points (1.11±0.03 and 1.09±0.02 μg g-1). Although were observed some PAHs concentrations above the established values by CONAMA and CETESB, the area is preserved. The study will provide previous information on PAHs concentrations in the area of the enterprise, providing information for the environmental impact study after the construction of the enterprise.
Evaluation of organic endocrine disruptors in water at Brazilian Multipurpose Reactor – RMB instalation area

The study of pollutants with organic and inorganic characteristics in groundwater and surface waters of a given region is an important tool in the assessment of pollution. Endocrine interferers are synthetic or natural chemicals that have the ability to act on the endocrine system of humans and animals by mimetizing natural hormones and may produce adverse effects on organisms, even in low concentrations (μg or ng.L-1). Anthropic activities are the major source of input of endocrine disruptors into the environment. The Brazilian government has a project to construct a multipurpose reactor, Brazilian Multipurpose Reactor (RMB), at the Iperó city, to improve the nuclear research Brazilian capacity. The object of this research in to analyze 14 organic compounds that may be present in the groundwater and surface waters of the RMB installation area. This is an unprecedented and extremely important study for the evaluated region; since it will provide guidance on the degree of contamination of the local waters before the construction begins. The study will also make it possible to verify if the construction of the RMB will offer environmental issues to the place. For the determination of the compounds of interest, a developed and validated analytical method was used. This methodology consists of the concentration of the samples by solid phase extraction (SPE) followed by quantification by gas chromatography coupled to the mass spectrometry detector (GC/MS). The water column particulate was also evaluated by ultrasonic extraction, followed by quantification by GC/MS. The results reveal that some of the compounds were found and it was due to anthropic activities in the vicinity of the regions. By initial analysis it was possible verify river that cross the RMB area present values below 0.05 μg L-1.
