AI Article Synopsis

  • * The analytical procedure involved ultrasonic extraction, clean-up, and HPLC-MS/MS analysis, and it was validated using samples from reed grass to assess PFAA distribution in different plant tissues.
  • * The method was used on plants near a fluorochemical plant in Northern Italy, finding PFAA levels in edible parts, which are important for assessing risks to humans from consuming these vegetables, as well as potential impacts on animals that consume forage from non-edible parts.

Article Abstract

A method for the determination of 12 perfluoroalkyl acids (PFAA) in vegetal samples was proposed. The analytical procedure was developed to optimize the detection of short-chain PFAA (C < 8) due to their higher potential to be translocated and bioaccumulated in plants than long-chain congeners. The method, based on ultrasonic extraction, clean-up and HPLC-MS/MS analysis, determined PFAA in different plant tissues allowing the PFAA distribution and partition in vegetal compartments to be studied. The performance of this analytical procedure was validated by analysing samples (root, stem and leaf) of reed grass. The validated method was then applied to graminaceous plants from an agricultural area impacted by a fluorochemical plant discharge (Northern Italy). The PFAA congeners were detected in most of the samples with ΣPFAA concentrations in the whole plant ranging from

Female reproductive aging often affects women's emotional, physical, and physiological well-being. Ovarian aging is characterized by fluctuations in reproductive hormones and determines the age at which menopause occurs. Understanding potentially modifiable factors that influence this process is essential for addressing health disparities, improving quality of life, and informing relevant public health strategies.

Article Synopsis
  • PFAS are toxic pollutants that are tough to break down due to strong chemical bonds.
  • Researchers found a method using PTFE, a harmless material, as a piezocatalyst to degrade PFAS effectively.
  • This technique achieved a 93.4% degradation of PFOA and works on other PFAS compounds, offering a promising solution for cleaning contaminated water.

Perfluoroalkyl chemicals are one of the most stable substances in industry and have become ubiquitous contaminants owing to their persistence in the environment. This study enrolled 1,953 participants aged ≥40 years old using data from the National Health and Nutrition Examination Survey (NHANES). We selected four perfluoroalkyl chemicals with a detection frequency of more than 80%, including perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), and perfluorooctane sulfonic acid (PFOS).

Observational studies on per- and polyfluoroalkyl substance toxicity in marine species: hints for the extrapolation of a screening value.

A statistical procedure has been developed to derive a screening value from an observational study related to the developmental toxicity observed in loggerhead turtle (Caretta caretta) eggs exposed to long chain per- and polyfluoroalkyl substances (PFAS). A dataset of 41 nests in which the hatching rate was inversely correlated with the increase in the PFAS concentration in unhatched eggs was processed via a categorical regression approach. After outliers identification and removal, categorical regression analysis tested the relationships of the outcomes with the following parameters: perfluoro-nonanoic (PFNA), decanoic (PFDA), undecanoic (PFUdA), and dodecanoic (PFDoA) acids; perfluoroctansulfonate (PFOS); polychlorobiphenyls (PCBs) 28, 52, 101, 138, 153, 180; lead (Pb), total mercury (Hgtot), and cadmium (Cd); and other factors, such as "nest site," "clutch size," "incubation duration," and "nest minimum depth," as confounders/modifiers of the hatching rate.

Background: Infections from the hepatitis B virus (HBV) are a major risk factor for hepatocellular carcinoma, one of the most common types of liver cancer. Circulating cell-free DNA (ccfDNA) in human plasma can be used as a non-invasive biomarker for diagnosing HBV-related liver diseases. The isolation of target ccfDNA sequences is often challenging due to the co-extraction of highly abundant non-target DNA from samples.
