“…Dispersive liquid–liquid microextraction was used for the pre-concentration of samples for the analysis of UV filters (Benedé et al 2014 ) or PFAS (Concha-Graña et al 2018 ) in seawater. However, if higher enrichment factors are required, solid phase extraction (SPE) is the method of choice for UV filters (Bratkovics and Sapozhnikova 2011 ), pharmaceuticals (Paíga et al 2015 ; Białk-Bielińska et al 2016 ), pesticides (Loos et al 2013 ; Rodríguez-González et al 2017 ; Li et al 2019 ; Xiao et al 2021 ), estrogens (Rocha et al 2012 ; Ronan and McHugh 2013 ; Heub et al 2015 ), and PFAS (Loos et al 2013 ; Brumovský et al 2018 ). Besides classical off-line SPE approaches, automated procedures directly coupled to LC systems have been utilized in the last years, e.g., for the analysis of UV filters in seawater samples (Oliveira et al 2010 ; Montesdeoca-Esponda et al 2012 ), triazine herbicides (Rodríguez-González et al 2016 ), and algal toxins (Zhang et al 2018 ; Merlo et al 2020 ; Wang et al 2021 ).…”

The Baltic Sea is among the most polluted seas worldwide. Anthropogenic contaminants are mainly introduced via riverine discharge and atmospheric deposition. Regional and international measures have successfully been employed to reduce concentrations of several legacy contaminants. However, current Baltic Sea monitoring programs do not address compounds of emerging concern. Hence, potentially harmful pharmaceuticals, UV filters, polar pesticides, estrogenic compounds, per- and polyfluoroalkyl substances, or naturally produced algal toxins are not taken into account during the assessment of the state of the Baltic Sea. Herein, we conducted literature searches based on systematic approaches and compiled reported data on these substances in Baltic Sea surface water and on methodological advances for sample processing and chemical as well as effect-based analysis of these analytically challenging marine pollutants. Finally, we provide recommendations for improvement of future contaminant and risk assessment in the Baltic Sea, which revolve around a combination of both chemical and effect-based analyses.

“…The risk assessment associated with the detected analytes was based on risk quotient ( RQ ) values [ 19 , 34 , 55 ]. For each individual contaminant found in WDP, the RQ ( contaminant) was calculated using the ratio of the mean or maximum measured environmental concentration ( MEC ) to the predicted no-effect concentration ( PNEC ), as shown by the Equation (1) [ 3 , 32 ].

“…Four risk levels were identified based on the value of RQ : negligible risk ( RQ < 0.01), low risk (0.01 < RQ < 0.1), medium risk (0.1 < RQ < 1), and high risk ( RQ > 1). Therefore, an RQ > 1 suggests high ecological risk and the environmental risk could not be excluded [ 22 , 32 , 34 , 69 , 70 , 71 ].…”

“…The exposure to the chemical pesticides is extremely destructive for the flora, fauna, and the environment, and poses a danger to human health [ 7 , 32 ]. In fact, several pesticides, including OPPs, are considered as endocrine disrupting compounds (EDCs), because of their modes of action and mechanisms in endocrine system disruption [ 19 , 33 ].…”

The intensive use of organophosphorus pesticides (OPPs) causes concern among authorities in different countries, as many of them, remaining unchanged for a long time, pose a threat to environmental sustainability. This study assessed the spatio-temporal trends of nine OPPs in the water dissolved phase (WDP), suspended particulate matter (SPM), and sediment samples from the Sele River estuary, Southern Italy. Samples were collected in 10 sampling sites during four seasons. The highest levels were found at the mouth (mean value 28.25 ng L−1 as WDP + SPM) and then decreased moving southwards to the Mediterranean Sea. Moreover, highest concentrations were detected in the warm season (July) with a mean value of 27.52 ng L−1. The load contribution to the Mediterranean Sea was evaluated in about 61.5 kg year−1, showing that the river was an important source of OPPs through discharge into the sea. The risk assessment revealed that no high-risk indices for the general-case scenario were observed, but for the worst-case scenario, potential risks were associated with chlorpyrifos, pyrimifos-methyl, and parathion, suggesting that OPP contamination should not be neglected. This study makes up the first record of OPPs in the surface waters of the Sele River and provides helpful data as a starting point for future studies.

“…Phorate Sulfone is an extremely toxic an organophosphorus pesticide that can dissolve in water, therefore it can pass from soil to groundwater (Henderson et al, 2004;Bala et al, 2015;Jariyal et al, 2018). Phorate Sulfone is the oxidized product of Phorate and Phorate has been banned in Europe since 2004 (Xiao et al, 2021).…”

Türkiye'de meyve ve sebze üretiminin çeşitli aşamalarında zararlıların kontrolü amacıyla belirli pestisitler kullanılmaktadır. İnsanlara, hayvanlara ve çevreye zararlı etkilerinden dolayı pestisit etken maddeleri ve bunların kalıntı limitleri yasal düzenlemelerle belirlenmiştir. Bu çalışmanın amacı, Türkiye'nin en kalabalık şehri olan İstanbul'da market ve manavlarda satılan ve yaygın olarak tüketilen meyve ve sebzelerde pestisit kalıntılarının riskini belirlemek ve vurgulamaktır. 100 meyve ve sebze örneğinde 393 pestisit etken maddesi, QuEChERS numune hazırlama metoduyla kütle spektrometrisine bağlı sıvı kromatografisi (LC–MS/MS) kullanılarak taranmıştır. Pestisitlerin ortalama geri kazanımları %76.5 ve %115.5 arasında, LOQ değerleri ise 0.01 mg kg-1’dır. Örneklerin %43'ünde pestisit kalıntısı tespit edilmiştir, 7 (%7)’si maksimum kalıntı limitinin (MRL) üzerinde pestisit kalıntıları içermektedir. Domates, çilek ve salatalık örneklerinde MRL üzerinde pestisit kalıntısı tespit edilirken, biber ve elma örneklerinde MRL'nin üzerinde pestisit kalıntısına rastlanmamıştır. İncelenen örneklerde 42 farklı pestisit kalıntısı tespit edilmiştir, en çok tespit edilen pestisit etken maddesi ise Acetamiprid'dir. Yasaklı pestisitlerden biri olan Phorate Sulfone ise bir çilek örneğinde tespit edilmiştir.
