“…For nearly three decades, environmental monitoring of the so called organic "micropollutants" has received great attention due to clues of aquatic toxicity, genotoxicity, endocrine disturbance, induction of antimicrobial resistance, and other effects [1][2][3]. The term micropollutant is used because these compounds are typically found at trace concentrations, from ng/L to µg/L, in aquatic environments or other environmental matrices [2,4,5].…”

The risks of pharmaceuticals and endocrine disrupting compounds (P&EDC) to the environment and human health are a current topic of interest. Hundreds of P&EDC may reach the environment, hence, there is a need to rank the level of concern of human exposure to these compounds. Thus, this work aimed at setting a priority list of P&EDC in Brazil, by studying their occurrence in raw and drinking water, calculating health guideline values (GV), and estimating the risks of population exposure to water intake. Data on the Brazilian pharmaceutical market as well as published data of the monitoring of Brazilian natural and drinking water have been collected by means of an exhaustive literature review. Furthermore, many foreign data were also collected to enable a comparison of the values found in Brazilian studies. A list of 55 P&EDC that have the potential to be found in Brazilian water is proposed, and for 41 of these a risk assessment was performed by estimating their margin of exposure (ME), by considering their occurrence in drinking water, and guideline values estimated from reported acceptable daily intake (ADI) data. For seven compounds the risk was deemed high (three estrogens and four anti-inflammatories), whereas for another seven compounds, it was regarded as an ‘alert’ situation. Although such risk analysis is conservative, since it has been calculated based on the highest reported P&EDC concentration in drinking water, it highlights the need to enhance their monitoring in Brazil to strengthen the database and support decision makers. An analysis of the occurrence of antimicrobial resistance agents (antibiotics, resistant bacteria, and resistance genes) in surface waters was also carried out and confirmed that such agents are present in water sources throughout Brazil, which deserves the attention of policy makers and health agents to prevent dissemination of antimicrobial resistance through water use.

“…Eventually, these compounds reach wastewater treatment plants where they are only partially removed, or transformed, and then released into receiving water bodies. Besides pharmaceuticals, wastewater treatment plants are typically unable to completely remove several classes of pollutants, such as personal care products, industrial run-offs or chemicals, micro/nano-plastics, and many others [ 1 , 2 , 3 , 4 , 5 ].…”

“…Other pathways for the movement of pollutants and contaminants into the environment include run-offs and wastewater from farms [ 6 , 7 ], storm water from urban and semi-urban areas [ 8 ], hospital discharges [ 2 , 5 , 9 ], and other non-point sources. Once these pollutants enter surface or ground water resources, they can eventually contaminate drinking and agricultural water systems, thus finding their way into various food commodities.…”

“…Once these pollutants enter surface or ground water resources, they can eventually contaminate drinking and agricultural water systems, thus finding their way into various food commodities. The presence of these pollutants and contaminants in food and the environment has received considerable attention in terms of research in identifying, monitoring, technologies for their removal, and implementing legislation to address the issue [ 2 , 4 , 5 , 10 , 11 , 12 , 13 , 14 ].…”

Current Applications of Magnetic Nanomaterials for Extraction of Mycotoxins, Pesticides, and Pharmaceuticals in Food Commodities

Environmental pollutants, such as mycotoxins, pesticides, and pharmaceuticals, are a group of contaminates that occur naturally, while others are produced from anthropogenic sources. With increased research on the adverse ecological and human health effects of these pollutants, there is an increasing need to regularly monitor their levels in food and the environment in order to ensure food safety and public health. The application of magnetic nanomaterials in the analyses of these pollutants could be promising and offers numerous advantages relative to conventional techniques. Due to their ability for the selective adsorption, and ease of separation as a result of magnetic susceptibility, surface modification, stability, cost-effectiveness, availability, and biodegradability, these unique magnetic nanomaterials exhibit great achievement in the improvement of the extraction of different analytes in food. On the other hand, conventional methods involve longer extraction procedures and utilize large quantities of environmentally unfriendly organic solvents. This review centers its attention on current applications of magnetic nanomaterials and their modifications in the extraction of pollutants in food commodities.

“…Massive efforts focused on precipitation, electrochemical recovery, solvent extraction, membrane separation, and ion exchange had been devoted to eliminating Cr (VI) from industry wastewaters [10][11][12][13][14]. However, numerous approaches were indicated as invalid and expensive, which led to secondary pollution to the environment as a consequence in some cases [15]. Adsorption had been regarded as the most effective method aiming to eliminate the contaminants within the aqueous systems [16].…”

Hydrothermal carbon (HTC) was prepared by the one-step hydrothermal method for Cr (VI) removal from wastewater, which was considered a “green chemistry” method. The specific surface area (SBET) of HTC was 85 m2/g with the pore size in range of 2.0–24.0 nm. FT-IR spectra analysis showed that the HTC had abundant chemical surface functional groups. The influence of adsorption parameters such as pH, HTC dosage, Cr (VI) concentration, and contact time on the removal efficiency of Cr (VI) had been investigated. When the initial concentration was 50 mg/L, pH = 6, amount of adsorbent was 0.2 g/50 ml, and adsorption time was 90 min; the Cr (VI) absorbed rate of HTC reached 98%. Batch adsorption experiments indicated that Cr (VI) adsorption data of HTC fitted the Freundlich isothermal and pseudo-second-order kinetic models. Overall, our findings provide a promising material in treatment of Cr (VI)-rich wastewater and give a clear picture of its application, which is worthy of further study.
