    Relatório de avaliação do Programa de Monitoramento Ambiental (PMA-Q) atendendo aos Compostos Químicos Estáveis do IPEN – 2015
    2017 - COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.; MARTINS, ELAINE A.J.
    Este relatório apresenta os resultados obtidos no desenvolvimento do PROGRAMA DE MONITORAMENTO QUÍMICO AMBIENTAL–PMA-Q dos Compostos Químicos Estáveis do Instituto de Pesquisas Energéticas e Nucleares – IPEN em 2015. Neste documento são apresentados e discutidos os resultados obtidos, em 2015, nos oito poços de monitoramento de água subterrânea, localizados nas instalações do IPEN, a partir de metodologias analíticas internacionalmente reconhecidas e discutidas com base nas legislações ambientais vigentes, emitidas por órgãos normativos e fiscalizadores, tais como Comissão Nacional de Energia Nuclear (CNEN), CETESB, Ministério do Meio Ambiente, por meio das resoluções CONAMA, além da solicitação do TAC (Termo de Ajuste de Conduta) do IBAMA. É apresentada também, uma avaliação temporal da qualidade química do efluente lançado pelo IPEN em rede coletora de esgoto, no ano de 2015, face aos valores estipulados nas legislações ambientais pertinentes.

    Guarapiranga Reservoir - pharmaceuticals and historical urban occupation in a water source
    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.

    Evaluation of PAHs in groundwater and surface waters at multipurpose reactor installation area
    2017 - PEREIRA, KAROLINE P.; MARTINS, ELAINE A.J.; COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.
    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.

    Determination of Polycyclic Aromatic Hydrocarbons (PAHs) in sediment samples of Brazilian Multipurpose Reactor (RMB) installation area
    2017 - SILVA, JULIANA C.; MARTINS, ELAINE A.J.; COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.
    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
    2017 - SILVA, LARISSA L.; MARTINS, ELAINE A.J.; COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.
    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.
