The occurrence of pharmaceuticals in influent wastewater samples (IWW) is a recurrent issue. monitoring their presence not only valuable from an environmental point view, but also as tool to analyze patterns human use by the so-called wastewater-based epidemiology. development analytical method based on solid-phase extraction followed liquid chromatography coupled tandem mass spectrometry monitor group seventeen including most representative for various therapeutic families IWW described this work. were collected during week six treatment plants located different cities and towns across Spain. developed provides acceptable figures merit with apparent recoveries ranging 42% 139%, low matrix effect (in general lower than ± 30%), quantification limits (MQL) between 1 ng/L 24 all compounds, except atenolol (58 ng/L). All studied found concentrations < MQL 10,393 ng/L, being highest tramadol. population normalized daily loads revealed that follows, general, similar pattern monitored.

Pharmaceutical residues in aquatic ecosystems pose significant environmental and public health challenges. Identifying the presence levels of these pharmaceuticals is crucial. This study developed an analytical method to detect used for Alzheimer's (AD) Parkinson's (PD) disease, including psychiatric drugs stimulant caffeine, targeting 30 compounds. Optimized mass spectrometric liquid chromatographic parameters enabled robust detection quantification. The methodology was applied 25 surface wastewater samples. Twenty-one compounds were detected eight drugs, five metabolites (citalopram N-oxide, citalopram propionic acid, desmethylcitalopram,

Present Trends in Analytical Methods for Determination of Multi-groups Environmental Contaminants Polyaromatic Hydrocarbons, Phthalates, Alkylphenol Ethoxylates, Alkylphenols, and Butylated Hydroxytoluene in River Sediments

Water Air & Soil Pollution, Год журнала: 2024, Номер 235(12)

Опубликована: Окт. 31, 2024

Abstract This paper is focused on an overview of developments and validation procedures in analytical methods for the detection quantification emerging contaminants from multiple groups environmental environment: polyaromatic hydrocarbons (PAHs), phthalate esters (PEs), alkylphenol ethoxylates (APEOs), alkylphenols (APs), butylated hydroxytoluene (BHT) river sediments. Especially, simultaneous extraction several analyte sediment samples currently uncommon, but perspective green chemistry, it highly desirable. In analysis, substances are determined at once instead through individual analyses, saving energy, time, chemicals while significantly increasing laboratory throughput. review reports different approaches monitoring presence four There plenty sampling techniques, with core grab being most employed present. Sample preparation a challenging part whole method, providing ample opportunity optimization accordance chemistry principles. Various schemes, including ultrasound-assisted accelerated solvent extraction, microwave-assisted energy-intensive techniques may be considered "green" due to their possibility reduce consumption organic solvents, which usually toxic. Quick, Easy, Cheap, Effective, Rugged Safe (QuEChERS) case satisfactory parameters well-evaluated utilized. The recent clean-up analysis two, three or showing promising results. Separation shortly discussed. Further optimizations methodologies needed, future field expected more efficient faster acquisition data real samples.
