“…LC-MS with thermospray ionization (LC-MS/TS) using the Zorbax Eclipse Plus C18 column was employed, resulting in an LOD of 0.48 × 10 −3 µg/L for dichlorvos [161]. The feasibility of utilizing cork-based passive samplers for water analysis was explored, and the findings from this research demonstrate the efficacy of employing cork-based passive samplers for the detection and measurement of triclosan in natural water sources [162]. Both cork passive samplers and miniaturized versions effectively identified and quantified triclosan, with cork passive samplers consistently revealing higher concentrations due to their enhanced sensitivity.…”

In the wake of rapid advancements in the pharmaceutical, food, and agricultural industries, the environment faces an increasing influx of diverse compounds, both intentionally and unintentionally released. These compounds fall into two categories: persistent and emerging pollutants. Persistent pollutants, characterized by their resistance to degradation and potential to accumulate in the environment, pose serious ecological threats. The Water Framework Directive (WFD) plays a pivotal role in monitoring and regulating these substances. This review discusses various contemporary analytical approaches to determine problematic substances, including benzo(a)pyrene, cypermethrin, dichlorvos, heptachlor, and heptachlor epoxide, aligning with the priorities outlined in the 2013 WFD classification. This review focuses on diverse water sampling methods, sample preparation techniques, and analytical methods, encompassing chromatographic, spectroscopic, and electrochemical approaches, with the primary goal of achieving the requirement laid on analytical methods used for the determination of maximum allowable concentrations defined in the WFD. Chromatographic methods, utilizing diverse mass spectrometers, have achieved detection limits as low as 10−6 μg/L, while modern electroanalytical techniques reach levels as low as 10−13 μg/L, reflecting an ongoing collective effort to enhance monitoring and safeguard the health of aquatic ecosystems. From sampling methods, large-volume sampling and passive sampling devices have been shown to be a cost-effective and modern solution, addressing limitations in traditional sampling methods, even if both of them face important pros and cons in terms of quantitative analysis.

Triclosan is one of emerging contaminants with antimicrobial and disinfection properties. It is commonly used in soaps, toothpastes, detergents, hand sanitizers, disinfectants, and other personal care products. Triclosan is ubiquitous in environmental samples and its concentration in natural waters is drastically increase owing to the use of hand-sanitizer during COVID-19 pandemic. Triclosan cancer classification has not been determined yet, but recent studies and government assessments had shown its adverse effect, including as endocrine disruptor compound (EDC) to living things even at relatively low concentration. Triclosan analysis in environmental samples are mostly performed on LC/MS or GC/MS instruments. However, these instruments are relatively expensive. This study was aimed to optimize GC/ECD for triclosan quantification as an alternative to MS based instruments. Triclosan standard solutions at several concentrations were injected into the GC/ECD and the result is evaluated. The result showed that GC/ECD was able to detect triclosan at 0.1 ppb with good repeatability showed by %RSD of 0.48 %. The calibration curve at range of 0.1 to 1000 ppb showed a good linearity (r=0.99999).
