AI Article Synopsis
Article Abstract
Endocrine disruptors are chemicals widely used worldwide by industries in a variety of applications. Routinely exposure to these chemicals, even if at low doses, can cause damage effects on human health. In the present study, we evaluated toxic effects of nine chemicals, among which phthalates, using various cell lines to inspect their capability to interfere with cell proliferation and viability. Alongside, we investigated their affinity for phospholipids to assess the possible passage through biomembranes. Experimentally determined logk values ranged from 1.37 to 3.49 whilst calculated log k spanned from 1.80 to 5.21, supporting the target contaminants to exhibit lipophilicity moderate or very high. The achieved results were related to pharmacokinetic and toxicological properties by ADMET predictor™ and EPI Suite™ software. Triclosan and 4-Nonylphenol were found to be the most toxic against all cell lines screened, showing an IC of 30 μM for triclosan on human keratinocytes and of 50 μM for 4-Nonylphenol on human colorectal adenocarcinoma cells. Overall, even if the phthalates showed higher IC values (ranging from 170 μM to 280 μM), we can assert that all contaminants herein tested were able to interfere with cell growth and viability.

Endocrine disruptors and bladder function: the role of phthalates in overactive bladder.
Front Public Health
December 2024
Department of Urology, Tianjin Medical University General Hospital, Tianjin, China.
Background: Phthalates, widely used as plasticizers, are pervasive environmental contaminants and endocrine disruptors. Their potential role in overactive bladder (OAB) pathogenesis is underexplored, necessitating further investigation into their impact on OAB using large-scale epidemiological data.
Methods: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2011 to 2018.

17-Estradiol (E2) is a natural steroidal estrogen essential for a variety of physiological functions in organisms. However, external E2, which is renowned for its potent biological effects, is also considered to be an endocrine-disrupting compound (EDC) capable of disturbing the normal operation of the endocrine system, even at nanogram-per-liter (ng/L) concentrations. Studies have revealed that medical and livestock wastewater can be contaminated with E2, which poses potential risks to human health.

The Bohai Sea (BS) is a semi-enclosed inland sea and China's most polluted coastal sea. With the rapid economic development of the circum-Bohai Sea region, large amounts of pollutants have been discharged into the BS, posing a significant threat to human health and the ecosystem. Great efforts have been made on investigating the levels of various pollutants in the BS; however, the priority pollutants which are required for the implementation of suitable environmental management and remediation measures in this system remain unclear.

These protocols describe a detailed method to determine the DNA damage and F-actin and microtubule defects of metaphase II oocytes caused by hexavalent chromium, Cr(VI), an endocrine disrupting chemical (EDC). The protocol provides systematic steps to determine protein expression encoded by pluripotency proteins such as Oct4, Nanog, and Cdx2 during early embryonic development. Occupational or environmental exposure to EDCs has significantly increased infertility in both men and women.

Phthalate acid esters (PAEs) and bisphenol A (BPA) are recognized as common endocrine disruptors associated with various adverse effects on human health. However, limitations in existing systematic studies, particularly in air detection, have raised concerns about potential health risks from inhalation exposure. In this study, PM samples were collected in Dongying, a petrochemical city, from October 27 to December 6, 2021.
