Abstract The early months of the COVID‐19 pandemic and associated shutdowns disrupted many aspects daily life thus caused changes in use disposal types chemicals. While records sales, prescriptions, drug overdoses, so forth provide data about specific chemical uses during this time, wastewater sewage sludge analysis can a more comprehensive overview within region. We analyzed primary from wastewater‐treatment plant Connecticut, USA, collected March 19 to June 30, 2020. This time period encompassed first wave pandemic, initial statewide stay at home order, phase reopening. used liquid chromatography–high‐resolution mass spectrometry targeted suspect screening strategies identify 78 chemicals interest, which included pharmaceuticals, illicit drugs, disinfectants, ultraviolet (UV) filters, others. trends over for identified using linear trend analyses multivariate comparisons ( p < 0.05). found related directly (e.g., hydroxychloroquine, publicized its potential treat COVID‐19, had elevated concentrations week following implementation US Emergency Use Authorization), as well evidence seasonal increases three UV‐filter compounds). Though surveillance has largely focused on measuring severe acute respiratory syndrome–coronavirus‐2 RNA concentrations, also show that are important revealing public environmental health effects pandemic.

The COVID-19 pandemic spread rapidly worldwide in the year 2020, which was initially restrained by drastic mobility restrictions. In this work, we investigated use of illicit drugs (amphetamine, methamphetamine, ecstasy, cocaine and cannabis), licit substances abuse (alcohol tobacco) during earlier months (March–July 2020) restrictions four Spanish (Bilbao its metropolitan area, Vitoria-Gasteiz, Castellón Santiago de Compostela) two Portuguese (Porto Vila do Conde) locations wastewater-based epidemiology (WBE). results show that no methamphetamine detected any monitored, while amphetamine only detectable from Basque Country area Vitoria-Gasteiz), with high estimated average usage rates (700–930 mg day−1 1000 inhabitant−1). remaining were all catchment areas. general, remarkable changes found population normalized loads compared to former years, except for (i.e. main metabolite, benzoylecgonine). For drug, a notable decrease discernible Castellón, Porto Compostela seemed continue rising trend, already initiated years. Furthermore, events ecstasy (3,4-methylenedioxymethamphetamine, MDMA) dumping sewage network confirmed enantiomeric analysis, one just prior lockdown second Bilbao July after relieving more stringent measures. latter could also be associated police intervention. comparison WBE (web) survey data, not provide information at local level, points towards contradictory conclusions some substances, thereby highlighting need stable networks capable near real-time monitoring drug use.

Analytical methodology for unveiling human exposure to (micro)plastic additives

TrAC Trends in Analytical Chemistry, Год журнала: 2024, Номер 173, С. 117653 - 117653

Опубликована: Март 12, 2024

This review describes a wide variety of analytical approaches for the assessment human exposure to organic chemicals associated with plastic additives, focusing on works published in last decade plasticisers, bisphenols, flame retardants and antioxidants. Physiologically based extraction tests serve as preliminary in-vitro assays determine bioaccessibility these compounds from micro/nanoplastics body fluids gastrointestinal tract, skin, or lung. Whenever plastic-laden become bioavailable, metabolism is be monitored through phase I II metabolites. In this regard, methods chromatography mass spectrometry biomonitoring parent their metabolites biological samples (mostly urine plasma) are discussed depth. also covers role wastewater-based epidemiology determining overall given population plastic-related species.
