Abstract
Acrylamide is pervasive, and its exposure poses numerous health risks. This study examines both the direct and transgenerational effects of acrylamide toxicity in Caenorhabditis elegans, focusing on physiological and behavioral parameters. Parental exposure to acrylamide compromised several aspects of nematode health, including lifespan, reproductive capacity, body dimensions, and motor and sensory functions. Notably, while exposure to low concentrations of acrylamide did not alter the physiological traits of the offspring-except for their learning and memory-these findings suggest a possible adaptive response to low-level exposure that could be inherited by subsequent generations. Furthermore, continued acrylamide exposure in the offspring intensified both physiological and perceptual toxicity. Detailed analysis revealed dose-dependent alterations in acrylamide's detoxification and metabolic pathways. In particular, it inhibits the gene gst-4, which encodes a crucial enzyme in detoxification, mitigates DNA damage induced by acrylamide, and highlights a potential therapeutic target to reduce its deleterious effects.

CHEMOSPHERE 2024; 352:141330. [PMID: 38301841 DOI: 10.1016/j.chemosphere.2024.141330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 01/26/2024] [Accepted: 01/28/2024] [Indexed: 02/03/2024]
Abstract
Polycyclic aromatic hydrocarbons (PAHs) are produced primarily during incomplete combustion of organic matter and in various industrial processes. They are widespread environmental pollutants that are of significant interest due to their potential toxicity. Humans can be exposed to PAHs through ingestion, inhalation and dermal contact. In the present study, ten urinary PAH biomarkers were determined in first-morning urine samples (n = 504) from the adult population (aged 18-65 years) residing in the Valencian Region of Spain. These samples were analysed using liquid-liquid extraction followed by high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS). All PAH biomarkers were quantified in more than 65 % of the urine samples. Naphthalene biomarkers, 1-hydroxynaphthalene (1OHNAP) and 2-hydroxynaphthalene (2OHNAP), exhibited the highest levels with geometric means (GMs) of 0.7 and 11.9 μg L-1, respectively. The 95th percentile of all PAH biomarkers ranged from 0.22 to 64.8 μg L-1. Estimated daily intakes (EDIs) for the analysed PAH families in the studied population ranged from 17 (pyrene) to 18581 (naphthalene) ng·kg-bw-1·day-1 (GM). Significant associations were observed between the quantified urinary metabolites of PAHs and smoking status, home location, annual household incomes, BMI, and the consumption of grilled food in the last 24 h. Hazard quotients (HQs) of naphthalene and consequently, hazard indexes (HIs) were above 1, especially for smokers. Therefore, potential health risks associated with PAH exposure in the target population could not be discarded.
