Impacts of Pulsed-Chronic Perfluoroalkyl Substances Mixture Exposure on Bioaccumulation and Reproductive Phenotypes in Soybean (Glycine max)
PFAS-contaminated irrigation water impacts soybeans, inducing early stress responses but enhancing pod and bean production. Short-chain PFAS accumulate in beans, while long-chain PFAS remain in roots. Stress adaptations, including upregulated aquaporins and oxidative responses, improve reproductive outcomes and bean nutritional content.
Digging Deep: Microbial PFAS-Degradation in Landfill Sediments
We explored the chemical and microbial barriers to PFAS biodegradation, emphasizing buried landfills as unique ecological niches with potential to enhance PFAS degradation processes.
Perfluorobutanoic Acid (PFBA) Induces a Non-Enzymatic Oxidative Stress Response in Soybean (Glycine max L. Merr.)
Perfluorobutanoic Acid (PFBA) Induces a Non-Enzymatic Oxidative Stress Response in Soybean (Glycine max L. Merr.)
PFBA, a short-chain PFAS, induces stress in soybeans, causing hormetic stimulation at lower exposure levels and inhibition at higher levels. Stress responses include oxidative stress, enriched non-enzymatic pathways, and circadian rhythm modulation, mirroring effects observed with long-chain PFAS
Influence of Perfluorobutanoic Acid (PFBA) on the Developmental Cycle and Damage Potential of the Beet Armyworm Spodoptera exigua (Hubner) (Insecta: Lepidoptera: Noctuidae)Â
Influence of Perfluorobutanoic Acid (PFBA) on the Developmental Cycle and Damage Potential of the Beet Armyworm Spodoptera exigua (Hubner) (Insecta: Lepidoptera: Noctuidae)Â
PFBA accumulates in plants and stimulates beet armyworm development. Exposed larvae showed increased weight gain, faster metamorphosis, and more leaf damage. The effects, observed in a dose-dependent hormesis model, suggest PFBA influences hormonal signaling pathways at low doses.
