Contamination characteristics in runof fractions from a nuclear facility in São Paulo, Brazil
2023 - FAUSTINO, MAINARA G.; MONTEIRO, LUCILENA R.; LIMA, SAMIA R.M.; SILVA, TATIANE B. de S.C. da; PIRANI, DEBORA A.; PEDREIRA FILHO, WALTER dos R.; GONZAGA, ROBERTA G.; COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.
The stormwater runoff may act as a nonpoint pollutant source and contributes to aquatic ecosystem quality decay in urban environments. The aim of this work was to evaluate the runoff characteristics on the transport of total solids and total metals, as well as pH and conductivity responses during the rainfall evolution. During 2017 and 2018, 12 rain events were monitored in 4 sampling stations at a car parking lot located at Nuclear and Energy Research Institute (IPEN/CNEN) in São Paulo/Brazil. A 4-chamber integrated collector allowed the sequential/temporal runoff evolution assessment. The runoff composition, in decreasing order of quantities, was Ca > K > Mg > Si > Al > Fe > Na > Zn > Mn > Sr > Ti > Mo > V > Cu > B > Pb > Ni > Ce > Sb > Cr > La > U > Th > Cd. The amount of total solids, Al, and Fe exceeded the Brazilian water quality standards. Principal component analysis (PCA) identified the elemental clusters linked to the facility activity, soil, and traffic/atmospheric-related deposition. The results show that the runoff characteristics could be differentiated by pollutant source. Factors such as seasonal variation, rain event intensity, air mass from oceanic or continental origin, spatial distribution inside the monitoring area, and the intensity of the first flush must be considered in order to disentangle the elemental clusters and pollution source contributions. In winter, continental air masses were associated with higher concentrations of heavy metals in the surface runoff. Spatial changes with no seasonal variation were observed for U, Th, La, and Ce.
Estimated pollutant load from Nuclear and Energy Research Institute (IPEN/CNEN-SP, Brazil)
2021 - SILVA, TATIANE B. de S.C. da; OLIVEIRA, CINTIA C. de; MARQUES, JOYCE R.; FAUSTINO, MAINARA G.; STELLATO, THAMIRIS B.; MONTEIRO, LUCILENA R.; PIRES, MARIA A.F.; COTRIM, MARYCEL E.B.
The quantification of the pollutant load received by a water body is one necessary step to keep its original standards, irrespective of the releasing source. Thus, to monitor and control the content of pollutants released in a water body assures the water will remain free from excessive pollution. Also, no harm to human health and the environment will occur. Hence, this paper aims to estimate the pollutant load of sanitary wastewater released by the Nuclear and Energy Research Institute (IPEN / CNEN-SP) in 2015 and 2016. The analysis of Cd, Pb, Cu, Cr, Zn, Ba, Ni, Mn, Fe, B, and Sn was performed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). These metals and the total fixed solids were used to estimate the pollutant load. Wastewater flow measurement was carried out using bromide (Br-) as a tracer and with the values from IPEN`s annual water consumption. Since 2006, this is performed as part of the Environmental Monitoring Program (PMA-Q), in compliance with the current Brazilian Environmental Legislation and with the Term of Conduct Adjustment requirements, agreed with the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA). Even the pollutants load has increased in 2015 and 2016, the monitoring frequency and water consumption have diminished in the last years. These facts increase the uncertainties in the monitoring and could lead to non-compliances with the monitoring laws.
Estimated pollutant load from nuclear and energy research institute (IPEN/CNEN-SP, Brazil)
2019 - SILVA, TATIANE B. de S.C. da; OLIVEIRA, CINTIA C. de; MARQUES, JOYCE R.; FAUSTINO, MAINARA G.; STELLATO, THAMIRIS B.; MONTEIRO, LUCILENA R.; PIRES, MARIA A.F.; CONTRIM, MARYCEL E.B.
Quantifying the pollutant load in a receiving water body is one of the needed steps to keep its original standards, irrespective of its releases source. Monitoring, and thus, controlling the amount of pollutants to be destined to the water body means ensuring water quality, keeping it free of excessive pollution and harm to human health and the environment. Hence, this paper aims to estimate the pollutant load of sanitary wastewater released by the Nuclear and Energy Research Institute (IPEN / CNEN-SP) during 2015 and 2016. The assay of Cd, Pb, Cu, Cr, Zn, Ba, Ni, Mn, Fe, B and Sn were performed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and As, Hg and Se by Graphite Furnace Atomic Absorption Spectrometry (GF-AAS). The metals and total fixed solids pollutant load estimative carried out, employed wastewater flow measurement, using bromide (Br- ) as tracer and the annual water consumption at IPEN. This evaluation is performed annually by IPEN since 2006 as part of the Environmental Monitoring Program (PMA-Q), in order to comply with the current environmental legislation and the Term of Adjustment of Conduct requirements, agreed with the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA).

Top down arsenic uncertainty measurement in water and sediments from Guarapiranga dam (Brazil)
2018 - FAUSTINO, M.G.; LANGE, C.N.; MONTEIRO, L.R.; FURUSAWA, H.A.; MARQUES, J.R.; STELLATO, T.B.; SOARES, S.M.V.; SILVA, T.B.S.C. da; SILVA, D.B. da; COTRIM, M.E.B.; PIRES, M.A.F.
Total arsenic measurements assessment regarding legal threshold demands more than average and standard deviation approach. In this way, analytical measurement uncertainty evaluation was conducted in order to comply with legal requirements and to allow the balance of arsenic in both water and sediment compartments. A top-down approach for measurement uncertainties was applied to evaluate arsenic concentrations in water and sediments from Guarapiranga dam (São Paulo, Brazil). Laboratory quality control and arsenic interlaboratory tests data were used in this approach to estimate the uncertainties associated with the methodology.
Total metals in stormwater runoff at the Nuclear and Energy Research Institute (IPEN), São Paulo – Brazil
2017 - FAUSTINO, MAINARA G.; MONTEIRO, LUCILENA R.; SILVA, TATIANE B. de S.C. da; STELLATO, THAMIRIS B.; SOARES, SABRINA M.V.; MARQUES, JOYCE R.; COTRIM, MARYCEL E.B.; PIRES, MARIA A.F.
Stormwater quality allows to evaluate if any pollutants load happens within its runoff. This work aims stormwater temporal and spatial profile characterization to assess environmental risk and to identify chemical tracers. Thus, a specific collector was built to sample collection, with four separate PVC tubes, and the collector allowed single event temporal and sequential evaluation, as long as each compartment was fulfilled. The collector was installed in the runoff direction in order to have maximum collection volume. Two collections were carried out in summer (January 2017) at two IPEN stations, in urban areas. Total metals analysis were performed, in addition to physicochemical data, such as pH, temperature and conductivity. The results had aluminum, iron and manganese present, and some elements, such as zinc, had a temporal distribution, with a decrease concentration within the collected volume. The preliminary results have as objective to assist the studies of urban water management.
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.
