Microplastics with different functional groups modulate cellular and molecular mechanisms of reduced graphene oxide toxicity on the green microalga, Scenedesmus obliquus
Researchers tested how microplastics with different surface chemistries interact with reduced graphene oxide, another emerging pollutant, and their combined effects on green algae. They found that certain microplastics reduced the toxicity of graphene oxide by adsorbing it, while others amplified the harmful effects depending on their surface functional groups. The study reveals that the combined impact of different nanomaterials in the environment can vary widely based on their chemical properties.

Researchers tested how microplastics, nanoplastics, and carbon nanofibers affect freshwater algae individually and in combination, finding that the combined effects were significantly worse than either pollutant alone. Nanoplastics combined with carbon nanofibers caused the most severe cellular stress, damaging cell membranes, increasing oxidative stress, and disrupting energy metabolism. Since algae form the base of aquatic food chains, this damage could cascade through ecosystems and affect the safety of water and seafood for humans.

The findings suggest that microplastics interacting with other environmental contaminants can amplify toxic effects in aquatic organisms.
Toxic effects of polystyrene nanoplastics and polycyclic aromatic hydrocarbons (chrysene and fluoranthene) on the growth and physiological characteristics of Chlamydomonas reinhardtii
Researchers tested how polystyrene nanoplastics combined with two common pollutants (chrysene and fluoranthene, found in vehicle exhaust and industrial emissions) affect green algae. The combination reduced algae growth, damaged cell membranes, and triggered oxidative stress more severely than either pollutant alone. Since algae are the foundation of aquatic food chains, this combined toxicity from nanoplastics and common environmental pollutants could have cascading effects on water ecosystems and the organisms that depend on them.

Researchers studied the combined effects of polystyrene nanoplastics and a common industrial pollutant (PCB-44) on a freshwater green algae species over both short and long exposure periods. They found that both contaminants individually inhibited algae growth and disrupted cell functions, but their combined presence intensified the damage. The study highlights that when nanoplastics and chemical pollutants co-exist in water, they can create compounding harmful effects on aquatic organisms.
The role of algal EPS in reducing the combined toxicity of BPA and polystyrene nanoparticles to the freshwater algae Scenedesmus obliquus
Researchers studied how polystyrene nanoplastics and the industrial chemical BPA affect freshwater algae when combined, and whether the algae's own protective secretions could reduce the damage. Carboxylated nanoplastics were the most toxic form, and the algae's natural exopolymeric substances helped buffer the combined toxicity. The findings suggest that biological interactions in real waterways may partially mitigate some harmful effects of nanoplastic pollution.

Researchers found that when graphene oxide, a nanomaterial used in many products, combines with polystyrene microplastics, the hybrid material is more toxic to zebrafish embryos than either substance alone. The increased toxicity was driven by oxidative stress, where the atomic interactions between the two materials amplified cell damage. This study highlights how microplastics can interact with other nanomaterials in the environment to create unexpected health risks.

The interfacial interaction between Dechlorane Plus (DP) and polystyrene nanoplastics (PSNPs): An overlooked influence factor for the algal toxicity of PSNPs
Researchers investigated how a flame retardant chemical called Dechlorane Plus interacts with polystyrene nanoplastics and found that the two pollutants bind together and become more harmful to algae than either one alone. When exposed to both contaminants simultaneously, algae showed reduced photosynthesis, greater growth inhibition, and significantly increased oxidative damage. The study suggests that the combined effects of nanoplastics and their chemical additives pose greater environmental risks than previously recognized.
