“…The concentrations of Al (0.2, 0.4, 0.6, 0.8, 1.0, and 2.0 mg/L) and Mn (0.1, 0.15, 0.3, 1.0, 1.5, and 3.0 mg/L) used in this study were based on the results of our previous study [ 28 ], in which we verified levels of Al and Mn within this concentration range in groundwater intended for human consumption. Stock solutions (1000 mg/L) of Al and Mn (SpecSolô, SEM-682, Jacareí, Brazil) were used.…”

“…In our previous study, we assessed the quality of groundwater in two cities in Mato Grosso do Sul, Brazil [ 28 ] since its population is supplied entirely by groundwater, which is normally consumed without prior treatment. We identified Al and Mn concentrations above the maximum limits allowed (0.2 and 0.1 mg/L, respectively) by regulation 396/2008 of the National Council for the Environment [ 29 ], which specifies the maximum limits allowed for metals in groundwater intended for human consumption.…”

The objective of this study was to use the same concentrations of aluminum (Al) and manganese (Mn) detected previously in groundwater above those permitted by Brazilian law and assess their cytotoxic and genotoxic effects in hamster ovary cell lines and their mutagenic effects through the Salmonella microsome assay. Chinese hamster ovary (CHO) and CHO-XRS5 cells were treated with different concentrations of Al and Mn (0.2 to 2.0 mg/L and 0.1 to 3.0 mg/L, respectively). The Ames test was used to analyze the concentrations of Al and Mn ranging from 0.025 to 1.0 mg/L and 0.0125 to 1.5 mg/L, respectively. Both metals showed cytotoxic effects on both cell lines and two bacterial strains (TA98 and TA100). The genotoxic effects of the highest concentrations of Al and Mn in cell lines showed nuclear buds, micronuclei, and DNA damage; however, none of the concentrations showed a positive mutagenic response in the Ames test. This is one of the few studies to demonstrate the cytotoxic effects of Al and Mn through the Ames test. In addition, the metals caused genomic instability in cell lines. Therefore, this study may help hasten the review of established regulatory standards for human consumption of groundwater.

“…In the recent years, the continuous increase in population, economic development and climate changes adversely distress the nature of water (Zhang et al,2019a, Pinto et al, 2019, Yadav et al, 2019. In a worst scenario, the combination of above factors may lead to non-availability of surface water in many parts of the country (Adimalla et al,2019a, Francisco et al, 2019, Wongsasuluk et,al 2014, Siirila et al, 2012. Insufficient rainfall in many arid and semi-arid regions being one of the major environmental issue had also resulted in the drastic reduction of surface water along with an increased extraction of groundwater to satisfy the water demand for domestic and agricultural uses especially in agriculture-based countries like India (Shahid et al, 2019, Qasemi et al, 2019, Tabassum et al, 2019, Shankar et al, 2010.…”

The main objective of this study was to evaluate the groundwater quality for domestic, agriculture use and to describe fluoride contamination in groundwater and their impacts on human health. 67 groundwater samples were collected and analyzed for major ions. Water Quality Index (WQI), Piper diagram and Gibbs diagrams were calculated to measure the suitability of groundwater for drinking purpose. The hazards index value was calculated to estimate the noncarcinogenic risk to adult (male, female) and children suggested by the United States Environmental Protection Agency (USEPA). The irrigation indices were calculated to evaluate the quality of water for irrigation purpose. Statistical methods such as principal component and hierarchical cluster analysis were used to analyses the interrelationship of data. Hydrochemistry of the samples shows, the major ions in the order of Ca 2+ >Mg 2+ >Na + and Cl->SO4in the study area. WQI value of groundwater, 74.62% of sample locations are good and 25.38 % of sample locations need primary treatment for drinking purpose. The results of the hazards index show that 65.67% of the sample locations exceeds the tolerable limit for non-carcinogenic risk (greater than one) for children higher than the risk level for Male and female. Statistical report of PCA and HCA reveals that Ca-Na-HCO3-F has positive loading and TDS-EC has negative loading. The study results show that rock-water interaction and anthropogenic activities are the major factors that influence the quality of groundwater. The continuous intake of excess concentration fluoride causes bone diseases and teeth problems.

Monitoramento e avaliação da qualidade da água de solução alternativa coletiva de abastecimento de escolas públicas do município de Itatiba, SP

Introdução: A segurança do abastecimento de água é de extrema importância para a saúde pública, principalmente para crianças que, em idade escolar, podem permanecer de 5 h a 8 h por dia nas escolas. A água pode conter uma variedade de contaminantes que, em níveis elevados, têm sido associados ao aumento de uma série de doenças em crianças.Objetivo: Avaliar durante 12 meses a qualidade das águas de poços utilizadas como soluções alternativas coletivas de abastecimento em dez escolas públicas do município de Itatiba (SP). Método: Foram coletadas amostras de água de poço, de reservatório e de bebedouro, totalizando 100 amostras, sendo analisados parâmetros químicos, físicos, organolépticos e microbiológicos previstos na Portaria de Consolidação n° 5, de 28 de setembro de 2017, anexo XX. Adicionalmente foi realizada uma pesquisa quanto à presença de matérias estranhas, incluindo os protozoários Cryptosporidium spp. e Giardia spp. Resultados: Três escolas exibiram resultados em acordo com a legislação. As demais apresentaram presença de microrganismos como bactérias (29,0% de coliforme total e 9,0% de Escherichia coli, no total de amostras analisadas) e protozoários (15,0%), além de resultados acima do valor máximo permitido (VMP) para cor aparente (8,0%), turbidez (11,0%), Fe (12,0%), Zn e Pb (5,0%). Conclusões: Os resultados em desacordo com a legislação interferem na qualidade das águas oferecidas nas escolas, estando associados à falta de investimento na infraestrutura dos poços e cloração da água, sendo observado um diferencial na escola que possui parceria com a empresa de tratamento de água do município. Esta parceria deve ser mantida e, se possível, expandida para as demais escolas.
