The reuse of treated wastewater for crop irrigation is vital in water-scarce semi-arid regions. However, concerns arise regarding emerging contaminants (ECs) that persist in treated wastewater and may accumulate in irrigated crops, potentially entering the food chain and the environment. This pilot-scale study conducted in southern Italy focused on tomato plants (Solanum lycopersicum L. cv Taylor F1) irrigated with treated wastewater to investigate EC uptake, accumulation, and translocation processes. The experiment spanned from June to September 2021 and involved three irrigation strategies: conventional water (FW), treated wastewater spiked with 10 target contaminants at the European average dose (TWWx1), and tertiary WWTP effluent spiked with the target contaminants at a triple dose (TWWx3). The results showed distinct behavior and distribution of ECs between the TWWx1 and TWWx3 strategies. In the TWWx3 strategy, clarithromycin, carbamazepine, metoprolol, fluconazole, and climbazole exhibited interactions with the soil-plant system, with varying degradation rates, soil accumulation rates, and plant accumulation rates. In contrast, naproxen, ketoprofen, diclofenac, sulfamethoxazole, and trimethoprim showed degradation. These findings imply that some ECs may be actively taken up by plants, potentially introducing them into the food chain and raising concerns for humans and the environment.

“…The results presented prove that the nutritional value of filtered water satisfactorily met the physiological growth of crops, without the need for using top-dressing fertilization. Urbano et al [13], Urbano et al [68] and Sandri et al [69], when irrigating the lettuce crop with wastewater, verified higher means of fresh mass compared to plants irrigated with supply water.…”

The objective of this study was to evaluate the adsorption capacity of orange pomace biochar, applying its benefits in irrigated agriculture. For this, a low-cost system for tertiary treatment using biochar was developed. The objective was also to compare the physicochemical and microbiological attributes of irrigation water with the limits established by the legislation. The impacts of wastewater from the filtration system on the soil and on the agronomic and biological characteristics of the lettuce crop were assessed. Biochar was produced in a muffle furnace and characterized by thermogravimetry and scanning electron microscopy (SEM). The experimental design was randomized blocks, in a 5 (irrigation depths) × 5 (combinations of water sources and fertilization) factorial arrangement, with three replicates. It was found that the use of biochar as a filter material improved the microbiological quality of wastewater. The water sources used in irrigation did not cause changes in soil salinity. Fertigation using wastewater that passed through the filtration system positively affected the agronomic characteristics of lettuce, with no need for top-dressing fertilization. Lettuce leaves produced in the experiment were acceptable for human consumption, according to the standards of Resolution-RDC No. 12, of 2 January 2001, of the National Health Surveillance Agency (ANVISA).

“…Nas últimas décadas, a ocorrência de micropoluentes no ambiente aquático tornou-se um assunto que tem gerado uma crescente preocupação ambiental. Isso ocorreu porque o efeito dessas substâncias em organismos não-alvo não é bem conhecido, mas os resultados obtidos em estudos prévios mostram que essas substâncias podem ser potencialmente prejudiciais em organismos nãoalvo (Carles et al, 2021;Gallego et al, 2021;Li et al, 2016;Ngweme et al, 2021;Yang et al, 2017).…”

Objetivo do estudo: O estudo visa determinar a dinâmica de descarga de micropoluentes no rio Amazonas a partir de uma ETE avançada e discutir a importância da gestão na minimização dos impactos.Metodologia: Foram analisados 13 micropoluentes: ibuprofeno (IBP), paracetamol (PCM), atenolol (ATL), loratadina (LTD), cloridrato de fexofenadina (FXF), amoxicilina (AMX), 17α-ethynil estradiol (EE2), cafeína (CAF), diclofenaco de sódio (DCF), estrona (E1), estriol (E3), bisfenol A (BPA), and bis(2-etilexil) ftalato (DEHP) em amostras de efluente vindas de diferentes estágios de tratamento de uma ETE com tecnologias de tratamento avançado, em diferentes períodos do dia. A presença de micropoluentes e sua quantificação foram realizadas usando técnicas de CL-EM e CG-EM.Originalidade/Relevância: Este é o primeiro estudo realizado em uma ETE de Manaus, cidade brasileira que está localizada em um dos mais extensos sistemas fluviais do mundo. Os dados obtidos são importantes para compreender o comportamento da descarga de micropoluentes no rio Amazonas e suas implicações.Principais resultados: Depois do tratamento, os micropoluentes paracetamol, cloridrato de fexofenadina, cafeína, diclofenaco de sódio, e, bis (2-etilexil) ftalato foram detectados no efluente final.Contribuições: Os resultados obtidos neste estudo indicam a necessidade de um gerenciamento integrado, considerando abordagens técnicas, governamentais, organizacionais e comunitárias para minimizar os efeitos da descarga de micropoluentes no meio ambiente.
