Nearly all environmental monitoring and research of chemical exposure in the aquatic environment relies on grab sampling water and/or sediment providing only a snapshot time. Passive provides more representative estimate compared to sampling, but current passive samplers have limited working range properties. We tested novel Composite Integrative Sampler (CIPS) that simultaneously accumulates both hydrophobic hydrophilic chemicals Tijuana River Estuary (TRE) U.S.-Mexico border. Quantitative targeted analysis detected 169 193 chemicals, 128 them were samples. These included polycyclic aromatic hydrocarbons, current-use legacy organochlorine pesticides, polychlorinated biphenyls, plasticizers, pharmaceuticals, consumer product stimulants, steroid hormones, haloacetic acids, fecal sterols. The had log KOW values from 0.2 8, by far largest ever reported for sampler, emerging concern. Our findings are stark contrast previous work TRE, where very few organic pollutants detected. conclude reason this discrepancy is ability CIPS preconcentrate large situ during deployment. highest contaminant concentrations closest This first demonstration sampler can accumulate such wide strong evidence transboundary movement Tijuana, Mexico US.

Contaminants of Emerging Concern, With an Emphasis on Nanomaterials and Pharmaceuticals

Green Chemistry, Journal Year: 2017, Volume and Issue: unknown, P. 291 - 315

Published: Nov. 29, 2017

Contaminants of emerging concern (CECs) include a diversity compounds, categorized as “emerging” because they are currently not monitored or regulated. However, these chemicals have the potential to accumulate in environment and may cause adverse effects humans wildlife. Despite their status, we can apply basic toxicological principles understand fate, transport, bioavailability, new approaches (i.e., outcome pathways) environmental impacts. This chapter focuses on nanomaterials pharmaceuticals case studies illustrate challenges associated with CECs. Nanomaterials complex macromolecular structures often display increased reactivity compared bulk counterparts. Pharmaceuticals potent by design aquatic life at very low concentrations. We propose that understanding reasons why some CECs, green chemists play an important role designing less toxic limited persistence thus reduce number CECs environment.

Seasonal variability in metal and metalloid burdens of mussels: using data from the German Environmental Specimen Bank to evaluate implications for long-term mussel monitoring programs

Environmental Sciences Europe, Journal Year: 2020, Volume and Issue: 32(1)

Published: Jan. 28, 2020

Abstract Background Metal and metalloid concentrations in mussels can vary between seasons. In biota monitoring, the sampling time is therefore an important issue. Within German Environmental Specimen Bank (ESB) program blue ( Mytilus edulis Complex) are sampled regularly since 1980s. The samples collected two-monthly intervals at two North Sea sites 6-month one Baltic site. All from site year combined to annual composite archived as sub-samples under cryogenic conditions. order investigate a possible reduction of number while maintaining comparability with long-term sample data, seasonal variability metals/metalloids was analyzed based on half-yearly bimonthly 2013, 2015 2017. Results Eckwarderhoerne seasonality comparable all 3 years (arsenic being only exception). At Koenigshafen cobalt, nickel, cadmium, copper, lead, arsenic 2013 but not 2017, selenium showed same years. 1 year, metals metalloids by magnitude observed different making it impossible select just representative point per that would provide information respective sample. Conclusions findings highlight importance carefully selecting when using monitoring. For ESB recommended continue current strategy analyze maintain data series, which special feature ESB.

A Simple and Rapid Ultra–High‐Performance Liquid Chromatography–Tandem Mass Spectrometry Method for the Quantitation of Pharmaceuticals and Related Compounds in Mussels and Oysters

Environmental Toxicology and Chemistry, Journal Year: 2021, Volume and Issue: 40(12), P. 3263 - 3274

Published: March 24, 2021

Abstract A simple, rapid ultra–high‐performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) method has been developed and optimized for the quantitation of a range pharmaceuticals, metabolites, related bioactive compounds in bivalve mollusc species mussels ( Mytilus edulis ) Pacific oysters Crassostrea gigas ). Shellfish tissues were extracted using simple solvent‐based extraction prior to concentration purification by pass‐through solid‐phase quantified stable isotope dilution MS/MS. The analytes covered therapeutic classes including antidepressants, anticonvulsants, beta‐blockers, antiplatelets. Of 34 included present study initially, 28 found demonstrate acceptable performance. Performance was assessed examining efficiencies, matrix effects, sensitivity, within‐ between‐batch precision. results show that as indicated HorRat accuracy values, is fit purpose.
