“…They reported that according to the model, the toxicity of both influent and effluent is mainly caused by the presence of PPCPs and there is a substantial reduction in ecotoxicity and human toxicity (between 42–85 %) after the treatment of WW. Furthermore, Naidu et al presented a risk‐based methodology for an improved method of managing ECs in surface water and WW. They recommended a trade‐off between risk‐reduction and cost‐effectiveness as an alternative solution for managing ECs in the environment.…”

The scarcity of industrial and domestic use water has become an important issue as industrial operations and localized pollution have burgeoned over the last decade. Wastewater (WW) treatment for recycling and reuse is gaining importance as an alternate source of water supply to circumvent water shortages. Wastewater treatment requires thorough planning, design, construction, and management of treatment facilities in order to discharge the treated water to the aquatic environment or for recycling and reuse. One detrimental effect of growing populations and urbanization has been the release of many persistent emerging contaminants (ECs) to the environment, mainly detected in WW. The entry of these ECs to the aquatic environment through wastewater treatment plants (WWTPs) may cause different ecological risks such as reproductive toxicity, endocrine disruption, and microbial resistance. The quantification of ECs (in ng or pg level) in complex matrices, such as WW samples recognized through non-target screening approaches, has played a key role in the planning and design of water treatment facilities. The purpose of this review is to provide information about advancements in wastewater treatment technologies such as constructed wetland (CW) and advanced oxidation processes (AOPs) and the fate of emerging contaminants during these treatments. Further, this review also reports the ecological effects of these contaminants and their by-products formed during various advanced WW treatment processes. The review also discusses advancements in different analytical techniques for the analysis of ECs in WW.

“…Skeletal fluorosis (including bone deformities), dental fluorosis, and kidney and liver malfunction are some of the consequences of exposure to drinking water high in F - [16][17][18][19]. High Fconcentrations (>1.5 mg/L, the WHO prescribed limit for drinking water) in groundwater that is used for drinking can adversely impact the health of people, which has been occurring in China [20][21][22][23][24][25].…”

A three-dimensional hierarchically structured flowerlike zeolite was synthesized using naturally occurring nanohalloysite (HNT) by hydrothermal methods. Halloysite a hydrated aluminum silicate with nanohollow morphology, microporosity, and environmentally friendly properties was chosen to be the sole precursor. The morphology and structure of the composite that was prepared was characterized using XRD, FT-IR, BET, TG, SEM, HRTEM, and NMR. SEM and HRTEM images indicated that the synthesized zeolite has a flowerlike hierarchical structure, with well-defined edges and uniform pore channels. FT-IR and NMR spectra indicated that different species of silicon and aluminum were present in the synthesized zeolite. The zeolite was applied in fluoride (F-) removal from aqueous solutions. Single-factor studies, including the initial concentration of F-, initial adsorbent concentration, and the effect of pH value on the adsorption properties, were investigated to evaluate the removal behavior of F- by the zeolite. The zeolite exhibited strong adsorption properties for fluoride ions (F-), with an adsorption capacity up to 161 mg g-1. The pseudo-second-order kinetics and Freundlich models were the best fit to the kinetics and isotherm experimental data, respectively.

“…In a review study, Gabet et al (2007), Naidu et al (2016), and Noguera-Ovedo and Aga (2016) gathered published papers from 1999 to 2007 highlighting information on hormone analysis in environmental matrices. In sample preparation prior to HPLC analysis, the most commonly used technique was filtration, solid phase extraction and online sample preparation.…”

“…Emerging pollutants are defined as compounds of varied origins -pharmaceuticals, illicit drugs, personal care products, industrial additives, among others -that can be found in environmental and biological matrices, which often not controlled by regulatory agencies although they may pose a potential risk to human health and the environment (Naidu et al 2016). Potential risks to human health and the environment include dysfunctions in the endocrine and reproductive systems of humans and animals, miscarriages, metabolic disorders and incidence of malignant neoplasms, as well as the introduction of resistant bacteria (Noguera-Oviedo and Aga, 2016).…”

Solid phase extraction using molecular imprinting polymers (MISPE) for the determination of estrogens in surface water by HPLC

et al. 2017

Estrogens are emerging pollutants and traditional sewage treatments unable to remove them. They are harmful to human health and to the environment. It is therefore important to evaluate the presence and concentration of estrogens in water bodies and environmental matrices. This work presents the development and application of a methodology for the determination of E1, E3, EE2 and E2 in surface waters using solid phase extraction with molecular imprinting polymers (MISPE) followed by identification and quantification by HPLC-DAD. Acetonitrile and water deionized acidified with phosphoric acid pH 3 (1:1, v/v), a flow rate of 1.0 ml min and the method was satisfactory for specificity and selectivity tests using caffeine, which is often found in water bodies receiving effluent, and DES, an estrogen used in the treatment of prostate cancer. Selected samples underwent cleanup and pre-concentration treatments using solid phase extraction with commercial phase (C18) and molecularly imprinted polymers (MISPE). The analysis of MISPE extracts indicate that it is possible to obtain results with greater sensitivity and precision for analyses of complex environmental matrices, demonstrating that the developed method can be applied in complex environmental matrices.Keywords: emerging pollutants, endocrine disruptors, environmental matrices.Extração em fase sólida utilizando polímeros de impressão molecular (MISPE) para a determinação de estrógenos em águas superficiais por HPLC RESUMOEstrogênios são poluentes emergentes e os tratamentos de esgoto tradicionais não são capazes de removê-los.

No presente trabalho, apresenta-se o desenvolvimento e aplicação de uma metodologia para a determinação de E1, E3, EE2, E2 em águas superficiais utilizando a extração em fase sólida com polímeros de impressão molecular (MISPE) seguida da identificação e quantificação via HPLC-DAD. A fase móvel empregada foi acetonitrila e água acidificada, com ácido fosfórico, pH 3, (1:1, v/v), vazão 1,0 mL min e o método mostrou-se satisfatório para testes de especificidade e seletividade usando cafeína encontrada em corpos hídricos que recebem efluentes, e DES, estrogênio utilizado em tratamento de câncer de próstata. Amostras selecionadas foram submetidas a clean-up e pré-concentração utilizando extração em fase sólida com fase comercial (C18) e polímeros de impressão molecular (MISPE). Os extratos MISPE analisados indicaram que é possível obter resultados com maior sensibilidade e precisão para análises de matrizes ambientais complexas; mostrando que o método desenvolvido pode ser aplicado em matrizes ambientais complexas.Palavras-chave: disruptores endócrinos, matrizes ambientais, poluentes emergentes.
