ClearReproductive Effects of Phthalates and Microplastics on Marine Mussels Based on Adverse Outcome Pathway
Researchers found that microplastics and the chemical plasticizer DEHP that leaches from them work together to disrupt reproductive function in female mussels by interfering with estrogen signaling and reducing hormone levels. While this study focused on marine mussels, DEHP is a known endocrine disruptor in humans as well, and the findings illustrate how microplastics can release harmful chemicals that affect hormone systems.
The types of microplastics, heavy metals, and adsorption environments control the microplastic adsorption capacity of heavy metals
Using nearly 5,000 data points, researchers mapped out which types of microplastics are best at absorbing which heavy metals from water. They found that the plastic type, the specific metal, and environmental conditions like pH and temperature all significantly affect how much metal sticks to the plastic. This is important because microplastics carrying heavy metals into the food chain could amplify the toxic effects of both pollutants on human health.
Aging Enhances the Ecotoxicological Effects of Biobased Microplastic Poly(Lactic Acid) and Its Adsorbed Tris(1-chloro-2-propyl)phosphate on Mussels
Researchers studied how the biodegradable plastic PLA, once aged in simulated marine conditions, affects mussels compared to fresh PLA. They found that aged PLA microplastics adsorbed more of the flame retardant chemical TCPP and caused greater toxic effects in mussels, including oxidative stress and immune responses. The study suggests that so-called biodegradable plastics may actually become more harmful as they weather in the ocean rather than safely breaking down.
