TL;DR: Hydrogen bonding and electrostatic interactions between HO-PBDEs and TRβ are important factors governing thyroid hormone activities, and the developed QSAR model had good robustness, predictive ability, and mechanism interpretability.

TL;DR: The results suggested that, for the tested OCPs, their ability to act as endocrine disruptors involves more than one mechanism, their (anti-)agonistic effects on different receptors should not be overlooked, and the potential for additive or synergistic effects must be taken into consideration in the risk assessment process.

TL;DR: The risk assessment showed that each watershed was at potential medium ecological risk based on their mean concentration (RQTotal > 1), and pesticides were the main compounds arising risks.

TL;DR: The estimated daily intake results show that the contribution of dietary intake and that based on the urine concentrations of VAs were far below the acceptable daily intake (ADI), and the EDIs from urine were significantly lower than those based on cooked foods.

TL;DR: The occurrence and distribution of six typical antibiotics in the main rivers of Hong Kong were investigated using high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ES-MS/MS), revealing that the antibiotics were widely distributed and posed no obvious ecological risk to aquatic organisms.
