From cohorts to molecules: Adverse impacts of endocrine disrupting mixtures

Nicolo Caporale et al.

Summary: This study found that exposure to EDC mixtures during early pregnancy is associated with language delay in offspring. The experimental results showed that at human-relevant concentrations, this mixture disrupts hormone-regulated and disease-relevant regulatory networks in the brain, as well as behavioral responses. Reanalyzing epidemiological data, it was found that up to 54% of children had prenatal exposures above experimentally derived levels of concern, resulting in a 3.3 times higher risk of language delay compared to the lowest decile of exposure.

Acute toxicity of bioplastic leachates to Paracentrotus lividus sea urchin larvae

Teresa Uribe-Echeverria et al.

Summary: This study assessed the toxic effects of three innovative bioplastic products on sea urchin larvae. The results showed that PVC toy was the most toxic material, PHB had slight toxicity, and PLA cups and PLA / PHA filament were innocuous. The presence of additives in bioplastics should be carefully addressed to ensure their safety.

Potential effects of biodegradable single-use items in the sea: Polylactic acid (PLA) and solitary ascidians

Guillermo Anderson et al.

Summary: The study found that discarded bioplastic products may have similar effects to conventional plastics on marine organism fertilization and biological accumulation, highlighting the need to reconsider the production and marketing of biodegradable and compostable plastics to prevent further negative impacts on ecosystems caused by mismanagement of bioplastic products.

Evaluation of the effects of additives on the properties of starch-based bioplastic film

Olugbenga O. Oluwasina et al.

Summary: This study investigated the effects of varying concentrations of dialdehyde starch and silica solutions on the properties of bioplastic films. Bioplastic films produced with dialdehyde starch solution exhibited better performance in terms of moisture content, solubility, and tensile strength compared to those produced with silica solution, demonstrating their suitability for food packaging applications.
