“…[ 116 ] The 2021 Toxic Release Inventory by the U.S. Environmental Protection Agency, which analyzed emissions of 536 fluorinated compounds, highlights global health concerns related to PFAS due to their persistence in the environment and prolonged biological half‐lives. [ 117 ] A deep understanding of PFAS toxicity, including their mechanisms of action in human and animal models, as well as the relationships between exposure levels and health outcomes, is essential for establishing public health guidelines, implementing risk mitigation strategies, and promoting environmental remediation. The collection of data for health risk assessments is challenged by the diverse chemical structures and properties of PFAS, often guarded as proprietary information.…”

In the realm of cancer therapy, the spotlight is on nanoscale pharmaceutical delivery systems, especially polymer‐based nanoparticles, for their enhanced drug dissolution, extended presence in the bloodstream, and precision targeting achieved via surface engineering. Leveraging the amplified permeation and retention phenomenon, these systems concentrate therapeutic agents within tumor tissues. Nonetheless, the hurdles of systemic toxicity, biological barriers, and compatibility with living systems persist. Fluorinated polymers, distinguished by their chemical idiosyncrasies, are poised for extensive biomedical applications, notably in stabilizing drug metabolism, augmenting lipophilicity, and optimizing bioavailability. Material science heralds the advent of fluorinated polymers that, by integrating fluorine atoms, unveil a suite of drug delivery merits: the hydrophobic traits of fluorinated alkyl chains ward off lipid or protein disruption, the carbon‐fluorine bond's stability extends the drug's lifecycle in the system, and a lower alkalinity coupled with a diminished ionic charge bolsters the drug's ability to traverse cellular membranes. This comprehensive review delves into the utilization of fluorinated polymers for oncological pharmacotherapy, elucidating their molecular architecture, synthetic pathways, and functional attributes, alongside an exploration of their empirical strengths and the quandaries they encounter in both experimental and clinical settings.This article is protected by copyright.

“…In evergreen trees in the subtropical region, only low-pH acidic conditions have a significant effect, while a high pH does not [ 1 , 9 ]. Studies have been conducted on the effects of SAR on plants [ 6 , 10 , 11 ] and nutrient elements [ 12 ]. Recent studies have also explored how the frequency of SAR influences soil microorganisms and plants [ 13 ].…”

“…There has been considerable research on the effects of SAR on the morphological features and photosynthetic activities of plants. More specifically, the related research on economically important coniferous species, such as Pinus massoniana (PM) and Cunninghamia lanceolata (CL), treated with SAR has mainly focused on biological characteristics, including growth [ 11 ], physiological functions [ 14 ], and ecological functions [ 15 , 16 ].…”

The effects of simulated acid rain (SAR) on the photosynthetic performance of subtropical coniferous species have not been thoroughly investigated. In this study, we treated two coniferous species, Pinus massoniana (PM) and Cunninghamia lanceolata (CL), with four gradients of SAR and then analyzed their photosynthetic activities through measurements of gas exchange, prompt fluorescence (PF), delayed fluorescence (DF), and modulated reflection at 820 nm (MR820). Gas exchange analysis indicated that the decrease in the net photosynthetic rate (Pn) in PM and CL was unrelated to stomatal factors. For the PF transients, SAR induced positive K-band and L-band, a significant reduction in photosynthetic performance index (PIABS), the quantum yield of electron transfer per unit cross-section (ETO/CSm), and maximal photochemical efficiency of photosystem II (Fv/Fm). Analysis of the MR820 kinetics showed that the re-reduction kinetics of PSI reaction center (P700+) and plastocyanin (PC+) became slower and occurred at later times under SAR treatment. For the DF signals, a decrease in the amplitude of the DF induction curve reduced the maximum value of DF (I1). These results suggested that SAR obstructed photosystem II (PSII) donor-side and acceptor-side electron transfer capacity, impaired the connectivity between PSII and PSI, and destroyed the oxygen-evolving complex (OEC). However, PM was better able to withstand SAR stress than CL, likely because of the activation of a protective mechanism.
