“…Fenthion (0.0026–0.0037 mg kg −1 ) exhibited values above the limit of quantification in tilapia from Aracoiaba, Castanhão, and Ilha Solteira [ 57 ]. Martins, Costa & Bianchini [ 58 ] found a maximum concentration 4.93 ng g −1 of chlorpyriphos in the muscle of Brazilian guitarfish ( Pseudobatos horkelli ). Zhang et al [ 13 ] found Fipronil sulfone in 16 seafood samples (ten shrimp and six fish) with concentrations ranging from 17.2 μg kg −1 to 181.5 μg kg −1 , and in two shrimp samples, above 50.3 μg kg −1 .…”

Accumulation of pesticides has a harmful impact on the environment and human health. The main goal of this work was to develop a method to determine and quantify the residues of thirteen pesticides in edible fish and bivalves such as parati (Mugil curema), seabass (Centropomus ssp.), mullet (Mugil brasiliensis), clams (Anomalocardia brasiliana) and mussel (Mytilus galloprovincialis) collected from Sepetiba Bay and Parnaiba River Delta (Brazil) between 2019 and 2020. Matrix solid-phase dispersion (MSPD) was used for extraction and quantification through gas chromatography coupled to tandem mass spectrometry (GC-MS/MS). The method was validated (linearity, accuracy and precision) for fatty fish (Salmo salar), lean fish (Mugil curema) and bivalves (Mytilus edulis). The survey found linear correlation coefficients (r) equal to or greater than 0.9 for almost all analytes. The relative standard deviations (RSD) of five replicates were less than 20% for almost all analytes at different concentrations in lean fish, fatty fish and bivalves. Most analytes showed satisfactory accuracy. Alachlor herbicide was found in samples of seabass, mussels, clams and parati with levels ranging between 0.55 to 420.39 μg kg−1 dw. Ethion was found in parati (maximum 211.22 μg kg−1 dw), mussels (15.1 μg kg−1 dw) and clams (maximum 44.50 μg kg−1 dw). Alachlor was found in clams (maximum 93.1 μg kg−1 dw), and bifenthrin was found in parati (maximum 43.4 μg kg−1 dw) and clams (maximum 42.21 μg kg−1 dw). The validated method was satisfactory for the determination of eleven pesticides in the fatty fish matrix, and thirteen pesticides in the samples of lean fish and bivalves. The presence of alachlor, ethion and bifenthrin stands out.

“…LMW-PAHs are more abundant in all tissues of Brazilian guitarfish. 118 A study reported that a higher level of LMW-PAH was detected in various organs of human autopsy samples, while HWM-PAH showed a lower concentration trend. 119 HMW-PAHs are more hydrophobic compounds, which are often more easily adsorbed by organic carbon, so they are not easily bioavailable, while LMW-PAHs have stronger water solubility and are easily bioavailable; in addition, HMW-PAHs may metabolize faster than LMW-PAHs.…”

The oxygen (OPAHs), nitro (NPAHs), hydroxyl (OH-PAHs), and alkylated (APAHs) derivatives of polycyclic aromatic hydrocarbon (PAHs) are ubiquitous pollutants in the environment. The concentrations of NPAHs, OPAHs, OH-PAHs, and APAHs are lower than that of PAHs in the environment, but the carcinogenic abilities of the derivatives are usually 10 to 1,000-fold higher than that of parent PAHs. There are three main pathways for the exposure of polycyclic aromatic compounds to humans, including inhalation, direct contact, and ingestion. After exposure by inhalation, they are mainly distributed in the lungs, affecting lung function and causing inflammation, asthma, etc. Due to the digestive system’s strong capacity for metabolism, intake of PAHs and the derivatives is primarily distributed in the digestive system and metabolized there. And it may lead to dysplasia of these organs and even to cancer. The skin is the primary site of direct contact with PAH derivatives. PAH derivatives can enter the bloodstream through all three contact pathways, thereby accumulating in various organs. This study aimed to summarize the influence of exposure pathways on tissue distribution and the health impact of PAH derivatives to provide references for future research and evaluation on public health.

“…Fish are one of the most impacted species by pollutants due to their relatively high trophic position in the aquatic ecosystem (Martins et al, 2020;Gray, 2002). One of the main effects of As is enzymatic reduction, hyperglycemia, and it substantially impacts the immune system (Kumari et al, 2017).…”
