“…However, the risk can be reduced through good practices, using personal protective equipment (PPE) in agriculture (WHO, 2006), so it is essential to know the contaminants and pollutants that may be in the reuse water. In addition, the transmission of diseases becomes less or even controlled through irrigation, culture and harvesting practices used, for example, application of drip irrigation (Morais et al, 2016;Mancuso and Santos, 2013;WHO, 2006). Gatta et al (2016) found that despite identifying microorganisms such as E. coli and Salmonella spp.…”

“…There are currently several examples of reusing water in agriculture in Brazil and worldwide (Fito and Van Hulle, 2021;Mancuso and Santos, 2013). Reused water is defined as the reuse of water from treated effluents (Morais et al, 2016). It can be classified according to Moura et al (2020), who conceptualized the origin of reuse water as follows:…”

Reused water is produced from treated effluents, and can be an alternative source of water for agriculture. However, its quality must be assessed to avoid causing damage to human and environmental health. This study evaluated the sanitary quality (bacteriological and physicochemical) of reused water samples for agricultural irrigation, compared with those described in Brazilian and international regulations. Bacteriological analyses were performed, and the results were compared with the norm of the Brazilian Association of Technical Norms (ABNT) NBR nº 13.969/1997. Physical and chemical analyses of the reused water samples were carried out, and the results were compared with the standards described by regulations: Resolution of the State Council for the Environment of Ceará No. 2 of 2017; Resolution of the Bahia State Water Resources Council No. 75 of 2010; and “Guidelines for Water Reuse” from the U.S. Environmental Protection Agency - EPA. According to Brazilian regulations, bacteriological analyses showed that the "chlorinated" and "polished" samples were suitable for agriculture. However, the “biological" sample was unsuitable for use, and showed a high level of thermotolerant coliforms (25.800 CFU / mL). According to bacteriological and physical-chemical analyses, the “polished” sample was only proper for agriculture irrigation. Therefore, the work suggests the creation of federal law regarding agricultural reuse to control the sanitary quality of water for human and environmental health. Keywords: agricultural reuse, agriculture, bacteriological and physicochemical evaluation, norms for reuse in agriculture.

“…O risco maior existe do contato da água de reúso com a parte externa, de permanecer resíduos contaminantes e poluentes sobre as folhas e caules. A transmissão de doenças se torna menor ou mesmo controlada por meio de práticas de irrigação, de cultura e de colheita utilizadas, por exemplo, aplicação de irrigação por gotejamento e uso de equipamentos de proteção individual pelos agricultores (MORAIS et al, 2016;MANCUSO;SANTOS, 2013;WHO, 2006). Além disso, a utilização da água de reúso pode representar uma fonte de nutrientes disponíveis para aplicação na agricultura MANCUSO;SANTOS, 2013).…”

“…No Brasil e no mundo, existem vários exemplos da utilização de água de reúso na agricultura (MANCUSO;SANTOS, 2013). A água de reúso é definida como a reutilização de águas provenientes de efluentes tratados (MORAIS et al, 2016). A agricultura é a atividade econômica que mais demanda água, cerca de 70% (WHO, 2013), e devido à escassez das fontes hídricas para esta atividade em diversas regiões, a água de reúso se torna uma alternativa para enfrentamento desse problema .…”

O objetivo do trabalho foi avaliar efeitos da irrigação com água de reúso sobre o DNA da microbiota no solo dos cultivos de hortaliça Petroselinum crispum. Em sistema construído em laboratório, foram cultivados Petroselinum crispum, regados por gotejamento com água de reúso e água potável, a temperatura e iluminação controlados. Foram feitas extrações de DNA total e reação da polimerase em cadeia (PCR), visando identificar no solo possível contaminação fecal. A quantidade extraída de DNA das amostras indicou que o uso da água de reúso contribuiu em média para aumentar 1,6 vezes a quantidade de microbiota no solo em relação ao controle. A PCR mostrou que os cultivos regados com água de reúso alteraram a microbiota no solo em função dos microrganismos, Adenovírus tipo 40 e 41 e Escherichia coli, presentes na água de irrigação. Conclui-se que, a água de reúso dentro dos padrões de qualidade sanitária representa uma fonte segura e sustentável para irrigação da agricultura, sendo feita por gotejamento, a fim de evitar danos à saúde humana e ambiental.

“…2 Reused water is defined as the reuse of water, which comes from treated effluents. 9 The reused water can be classified according to Moura et al Considering that, according to GONÇALVES (2009), black waters are effluents from toilets, basically containing feces, urine and toilet paper or from feces and urine separating devices, having in their composition large amounts of fecal matter and toilet paper; suspended solids, largely sedimentable; (iii) Industrial reuse, coming from water from the industrial activities of the enterprise itself (direct internal reuse) or from external reuse.

Determining the presence of endocrine disrupting substances in waters is a relevant aspect for monitoring environmental health. Given its relevance, it is important to use methods that can make the total concentration of substances with estrogenic activity (eg endocrine disruptors), being faster, and without the use of compounds that pollute the environment. The purpose of the study was to compare the effectiveness of the methods of concentration by lyophilization and by vacuum concentration of substances with estrogenic activity present in reused water, using the commonly used methodology, solid phase extraction. Three methods were compared: solid phase extraction, lyophilization, and vacuum centrifugation. Sample aliquots of reused water received 17β-estradiol at a final concentration of 2 μg L-1 and were concentrated by the three methods. The analysis of estrogenic activity was performed by the in vitro YES (Yeast Estrogen Screen) assay. The results showed that the vacuum centrifugation, solid phase extraction and lyophilization methods had different percentages in the recovery of substances with estrogenic activity, being 45%, 40%, and 31%, respectively. The study pointed out that the lyophilization and vacuum centrifugation methods were effective as alternative methods for concentrating samples containing substances with estrogenic activity.
