“…The occurrence and fate of pharmaceuticals and personal care products (PPCPs) in water bodies have caused increasing environmental concern for their possible threats to aquatic environment and human health (Kolpin et al, 2002;Kummerer, 2003;de Voogt et al, 2009;Lajeunesse et al, 2012;Kostich et al, 2014).…”

“…Water resources are exposed to the presence of xenobiotic compounds and consequently environmental degradation processes are observed [2,3]. The main source of release of these chemicals in the environment is the discharge of wastewater as a result of the inadequacy of the treatment processes used in the sewage treatment plants (STPs) [1,2,[4][5][6]. Among these compounds are contaminants of emerging concern (CECs) which include different chemical classes such as pharmaceuticals, personal care products, steroids, surfactants, nanomaterials, disinfectants, drugs of abuse, Blife-style compounds^, and others [5,[7][8][9][10].…”

New approach to the determination of contaminants of emerging concern in natural water: study of alprazolam employing adsorptive cathodic stripping voltammetry

Contaminants of emerging concern (CECs) are chemicals, including pharmaceutical and personal care products, not commonly monitored in the aquatic environment. Pharmaceuticals are nowadays considered as an important environmental contaminant. Chromatography methods which require expensive equipment and complicated sample pretreatment are used for detection of CECs in natural water. Thus, in this study we proposed a simple, fast, and low-cost voltammetric method as a screening tool for the determination of CECs in natural water prior to chromatography. A case study was conducted with alprazolam (benzodiazepine). The method was optimized and validated in-house. The limit of quantification was 0.4 μg L(-1) for a 120 s preconcentration time. The recoveries ranged from 93 to 120 % for accuracy tests. A further proposal aim was to determine for the first time the occurrence of alprazolam in Brazilian river water and to evaluate its potential use as a marker of contamination by wastewater.

“…FLU was measured concentration at 120.7 ng l -1 in the influent, <dl in effluent (Silva et al, 2014). Lajeunesse et al, (2012) reported that the concentrations of the antidepressants, including CBZ, FLU, LZP in the influent wastewater ranged from <dl to 3124 ng l -1 , and effluent wastewater ranged from 6.6 to 2956 ng l -1 . The antidepressants DZP and LZP were quantified at concentrations varying from <dl to 250 ng l -1 in the influent and effluent wastewater (Verlicchi et al, 2012).…”

In this study, an analytical methods for determination of antidepressants including (diazepam (DZP), lorazepam (LZP), carbamazepine (CBZ), fluoxetine (FLU)) was developed. The concentration of antidepressants was monitored in Konya Urban Wastewater Treatment Plant influent and effluent samples for one years. Environmental risk assessment was performed with detected concentration with treatment plant effluent wastewater by hazard quotient (HQ) methods. Oasis HLB cartridges with SPE system was used for extraction of wastewater samples. The effect of sample volume and pH, different analyte concentration, pretreatment and matrix on efficiency of cartridges were optimized. Quantitative analyses of the target compounds were performed by LC/MS-MS system. Recoveries of antidepressant compounds from fortified wastewater were over 87% for three different fortification levels. The limits of detection were determined between 0.006 and 0.118 ng l -1 . CBZ, FLU and LZP concentration in influent varied from 6.3 to 135.6 ng l -1
