“…In contrast with the previous studies, TBD was consistently detected at the 8 WWTPs in Thailand at concentrations ranging between 0.63 and 7.55 µg/L and 0.35 and 8.32 µg/L in the ANNUAL LITERATURE REVIEW influent and effluent, respectively (Juksu et al, 2019). Results from this study suggested very low removal efficiency (mean removal rate < 15%).…”

A review of 79 papers published in 2019 is presented. The topics ranged from detailed descriptions of analytical methods, to fate and occurrence studies, to ecological effects and sampling techniques for a wide variety of emerging contaminants likely to occur in agricultural environments. New methods and studies on veterinary pharmaceuticals, antibiotics, anthelmintics, and engineered nanomaterials in agricultural environments continue to expand our knowledge base on the occurrence and potential impacts of these compounds. This review is divided into the following sections: Introduction, Analytical Methods, Antibiotics in Agroecosystems, Pharmaceutical Fate and Occurrence, Anthelmintics and Engineered Nanomaterials.

“…In recent years, biocidal substances in the aquatic environment have received an increasing attention because of (i) their many uses especially in urban areas (Bester et al 2008;Bollmann et al 2014b;Paijens et al 2020;Wieck et al 2018), (ii) their transfer into the aquatic environment via wastewater or stormwater discharges (Bollmann et al 2014a;Burkhardt et al 2011;Juksu et al 2019;Wicke et al 2015), and (iii) their negative effect on aquatic organisms (Mohr et al 2008;Vermeirssen et al 2018). Indeed, biocides are toxic and may cause long-term adverse effects to aquatic ecosystems even at low concentrations, such as endocrine disruption in zebrafish larvae (Jiang et al, 2015) or behavioural disturbance in zebrafish embryos (Andrade et al, 2016).…”

A robust method is provided to analyze 18 hydrophilic and hydrophobic biocides in both dissolved and particulate fractions of five types of urban and surface waters using high performance liquid chromatography coupled to tandem mass spectrometry. The linearity, accuracy and intermediate precision were validated. The target biocides were enriched by solid phase extraction using Chromabond HR-X 200 mg cartridges and eluted with methanol, ethyl acetate and dichloromethane. Suspended matter was extracted by microwave-assisted extraction in methanol and dichloromethane. Recoveries and variability (respectively >75% and < 30% for most of the target biocides and matrices) made it possible to quantify biocides at trace level in all matrices. LOQs were in the range of ng/L in the dissolved fraction and in the range of ng/g.dw in the particulate fraction for most of the biocides and matrices and were generally lower than those reported in previous studies. The method was successfully applied to surface water, treated and untreated wastewater, combined sewer overflows, and stormwater providing, unique data in these matrices for some substances, in particular with respect to particle contamination. In urban waters, concentrations of most of the biocides ranged from 10 to 200 ng/L. Diuron, isothazolinone and benzalkonium concentrations could reach 0.9, 0.9 and 20 µg/L respectively. In rivers, most of the biocides were measured at less than 10 ng/L, but higher concentrations were observed for benzalkoniums (up to 200 ng/L) or after rain events, which indicates biocide transfer from urban surfaces into the aquatic environment during wet weather.

“…Comparing local discharges of WWTPs or CSOs with mass loads that are transiting within the Seine River could be a first approach. [48] in several regions of Thailand were in the same order of magnitude for BIT and thiabendazole but seven times higher for carbendazim. These differences may partly originate from the methodology itself (use of average concentrations and daily flow in these studies vs. statistical distributions in the present approach, sampling campaigns, etc.)…”
