“…Contaminants of emerging concern (CEC) are chemical or biological substances with potential risks to humans and the environment [ 1 , 2 ]. These contaminants encompass personal care products, pharmaceutically active compounds (PhACs), surfactants, flame retardants, and antibiotic-resistant genes, as well as other non-regulated substances [ 3 , 4 ]. They have been introduced into the environment through the disposal of wastewater [ 5 , 6 ] since conventional treatment processes commonly used in wastewater treatment plants (WWTPs) are not effective in removing these contaminants [ 7 , 8 ].…”

The present work investigates nanofiltration (NF) and ultrafiltration (UF) for the removal of three widely used pharmaceutically active compounds (PhACs), namely atenolol, sulfamethoxazole, and rosuvastatin. Four membranes, two polyamide NF membranes (NF90 and NF270) and two polyethersulfone UF membranes (XT and ST), were evaluated in terms of productivity (permeate flux) and selectivity (rejection of PhACs) at pressures from 2 to 8 bar. Although the UF membranes have a much higher molecular weight cut-off (1000 and 10,000 Da), when compared to the molecular weight of the PhACs (253–482 Da), moderate rejections were observed. For UF, rejections were dependent on the molecular weight and charge of the PhACs, membrane molecular weight cut-off (MWCO), and operating pressure, demonstrating that electrostatic interactions play an important role in the removal of PhACs, especially at low operating pressures. On the other hand, both NF membranes displayed high rejections for all PhACs studied (75–98%). Hence, considering the optimal operating conditions, the NF270 membrane (MWCO = 400 Da) presented the best performance, achieving permeate fluxes of about 100 kg h−1 m−2 and rejections above 80% at a pressure of 8 bar, that is, a productivity of about twice that of the NF90 membrane (MWCO = 200 Da). Therefore, NF270 was the most suitable membrane for this application, although the tight UF membranes under low operating pressures displayed satisfactory results.

“…The screening of the pre-selected twenty-seven PPCPs was based on the annual consumption, reported toxicity and environmental persistence (Cmed, 2021;Roveri et al 2021b). These PPCPs, were recently identi ed as having the greatest relevance for studies of environmental monitoring in Brazil(Chaves et al, 2021). The occurrence of these chemical compounds was somewhat expected in the hereby study area as result of the wastewater discharges from industrial and domestic e uents(Krogh et al, 2017; Asfa et al, 2020;Shahriar et al, 2021).…”

The worldwide occurrence of pharmaceuticals and personal care products (PPCPs) in aquatic ecosystems is reason for concern, since these emerging micro pollutants, includes a large and diverse group of organic compounds, with continuous input, high environmental persistence and potential threat to biota and human health. The aim of this study was to evaluate, for the rst time, the occurrence of twenty-seven PPCPs of various therapeutic classes (including cocaine and its primary metabolite, benzoylecgonine), in the coastal waters of Santa Catarina, southern Brazil. Water samples were taken in November 2020, during the low tide periods, at eight sampling points located along the coast of Santa Catarina, covering its entire geographical extension. Sampling was carried out in triplicate and at different depths of the water column. Nine compounds were detected through liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS): caffeine (12.58-119.80 ng/L), diclofenac (1.398-7.920 ng/L), losartan (0.432-3.200 ng/L), cocaine (0.0248-0.1686 ng/L) and benzoylecgonine (0.0146-1.094 ng/L) were quanti ed in 100% of the samples; carbamazepine (0.0242-0.2720 ng/L) was quanti ed in 75% of the samples; acetaminophen (0.212-10.040 ng/L) was quanti ed in 60% of the samples; and both atenolol (1.13-2.50 ng/L) and orphenadrine (0.073-0.0886 ng/L) were quanti ed in 25% of the samples. The other PPCPs were below the limit of detection (LOD). The highest occurrence of these compounds was detected in the northern and central coastal region of Santa Catarina, namely in Penha and Palhoça cities. The sources of these compounds may be associated with areas with high population density, awaited by tourism, with consequent production of sanitary sewage and solid waste. The ecological risk assessment of these substances in the aquatic ecosystems showed that 67% and 77% of the compounds respectively presented no ecological risk, acute and chronic, but 44% presented low to moderate risks for acute and chronic effects in the three trophic levels evaluated. The occurrence of these chemical compounds can imply deleterious effects on the environmental health of Santa Catarina coastal zone, and therefore deserve more acute and directed attention.

“…Nevertheless, the bioconcentration and histopathological effects of these metals in the fish tissue is also important. Organ/tissue bioaccumulation and/or bio-concentration of heavy metals are important markers for toxicity monitoring and could serve as indicators for contaminants or pollutants to which humans are at risk of exposure (Chaves et al, 2021). Therefore, periodic monitoring of contaminants in fish and water bodies is imperative (Meche et al, 2010;Yilmaz et al, 2007;Zhao et al, 2012).…”

Fish is a cheap source of omega- 3 polyunsaturated fatty acids for humans. However, the presence of toxic heavy metals in water can be detrimental to both fish and humans. The aim of this study was to investigate the levels of heavy metals in the liver, kidney and gills of cat fish obtained from Kwalkwalawa River, Sokoto. Water, sediments, blood and tissue samples of (10) cat fish (Clarias gariepinus) species caught from Kwalkwalawa river were analysed quantitatively for the presence of zinc, copper, lead, chromium and cadmium using atomic absorption spectrophotometer. Bioaccumulation of these heavy metals was estimated in these organs. Results showed that lead concentrations in the water was significantly higher (p < 0.05) compared to the sediment sample. Also, copper and lead accumulated most in the liver and kidney when compared with that observed for the gills. In conclusion, lead and cadmium levels in the samples were above WHO certified limits hence the concentration of metals in this water should be monitored periodically.
