Despite the increasing health risks shown by continuous detection of organophosphate esters (OPEs) in biota recent years, information on occurrence and potential OPEs marine mammals remains limited. This study conducted first investigation into body burdens 10 traditional (tOPEs) five emerging (eOPEs) cetacean species (n = 84) from northern South China Sea (NSCS) during 2005–2021. All OPEs, except for 2-ethylhexyl diphenyl phosphate (EHDPHP), were detected these cetaceans, indicating their widespread NSCS. Although levels ∑10tOPEs humpback dolphins remained stable 2005 to 2021, concentrations ∑5eOPEs showed a significant increase, suggesting growing demand new-generation China. Dolphins proximity urban regions generally exhibited higher OPE than those rural areas, mirroring environmental trends occurring this area. congeners, EHDPHP, maternal transfer ratio >1, that dolphin placenta may not be an efficient barrier OPEs. The observed correlations between hormones (triiodothyronine, thyroxine, testosterone) indicated exposures might have endocrine disruption effects population.

Organophosphorus flame retardants (OPFRs) have been frequently detected with relatively high concentrations in various environmental media and are considered emerging pollutants. However, their biological effect underlying mechanism is still unclear, whether chlorinated OPFRs (Cl-OPFRs) cause adverse outcomes the same molecular initial events or share key (KEs) remains unknown. In this study, vitro bioassays were conducted to analyze cytotoxicity, mitochondrial impairment, DNA damage mechanisms of two Cl-OPFRs. The results showed that these Cl-OPFRs, which similar structures, induced severe cellular damages via different mechanisms. Both tris(2-chloroethyl) phosphate (TCEP) tris(1-chloro-2-propyl) (TCPP) oxidative stress-mediated impairment damage, as shown by overproduction intracellular reactive oxygen species (ROS) superoxide. Furthermore, caused TCPP resulted p53/p21-mediated cell cycle arrest, evidenced flow cytometry real-time PCR. At levels, increased sub-G1 apoptotic peak upregulated p53/Bax apoptosis pathway, possibly associated its stronger cytotoxicity. Although structurally TCPP, TCEP did not induce KEs. These provide insight into toxicity Cl-OPFRs structures but mechanisms, great significance for constructing outcome pathways determining intermediate

Exposure to organophosphate esters (OPEs) remains a significant concern, especially in aquatic systems where these compounds can bioaccumulate organisms. However, limited information exists regarding their potential health risks humans through the food web tropical ecosystems. This study investigated levels, bioaccumulation, and trophic transfer of OPEs sediments marine fish species from Cartagena Barbacoas bays, Colombia. Twenty target were quantified fish. The average concentrations ∑18OPEs ranged 2.80 115 ng/g dry weight (dw), while ∑20OPE 212 1968 lipid (lw), with highest found carnivorous species. Trophic magnification factors (TMF) for varied 11.0 25.8 such as 2-ethylhexyl diphenyl phosphate (EHDPP), 4-isopropylphenyl (4IPPDPP), tris(2-isopropylphenyl) (T2IPPP), tricresylphosphate (TCP), indicating biomagnification within web.
