ClearExperimental Dataset: Microplastics-Glyphosate Study in Microalgae
Researchers compiled raw experimental data supporting a study on the interaction between microplastics and glyphosate in the freshwater green alga Chlamydomonas reinhardtii, providing the underlying dataset for published findings on combined contaminant effects.
Combinatory effects of microplastics and emerging contaminants on alga Chlamydomonas reinhardtii
Researchers exposed the green alga Chlamydomonas reinhardtii to two types of microplastics found in face washes — PVC and an acrylate copolymer — along with the preservative 2-phenoxyethanol, finding that combined exposure had distinct effects on algal growth compared to individual pollutants. This is relevant because microplastics rarely occur alone in the environment, and their interactions with other chemicals can either amplify or dampen ecological harm.
Co-Exposure to Glyphosate and Polyethylene Microplastic Affects Their Toxicity to Chlorella vulgaris: Implications for Algal Health and Aquatic Risk
Researchers assessed the individual and combined toxicity of polyethylene microplastics and glyphosate to the microalga Chlorella vulgaris in acute and chronic exposures. The combination caused greater toxicity than either contaminant alone, particularly at chronic exposure durations, indicating synergistic effects relevant to agricultural runoff contamination.

Researchers tested the effects of mixed polypropylene and PVC microplastics at five different ratio combinations on a freshwater microalgae community, finding that mixture composition affected algal growth and survival differently than either polymer alone.
Influence of polystyrene microplastics on the growth, photosynthetic efficiency and aggregation of freshwater microalgae Chlamydomonas reinhardtii
Polystyrene microplastics at concentrations of 5–100 mg/L inhibited the growth and photosynthetic efficiency of the freshwater microalga Chlamydomonas reinhardtii, and promoted cell aggregation at higher concentrations, with effects scaling with dose.
Aged polyethylene microplastics modulate herbicide and antibiotic bioavailability and plant responses: a case study with glyphosate and tetracycline
Researchers generated experimental data on how aged polyethylene microplastics affect the behavior of the herbicide glyphosate and the antibiotic tetracycline in hydroponic plant growth systems. The dataset includes measurements of pollutant sorption, plant photosynthetic pigments, and antioxidant enzyme activity in rapeseed plants exposed to various combinations of microplastics and chemicals. The study suggests that microplastics can modulate how other environmental contaminants interact with plants.
Microplastic interactions with freshwater microalgae: Hetero-aggregation and changes in plastic density appear strongly dependent on polymer type
Researchers studied interactions between microplastics and freshwater microalgae, finding that microplastics can physically attach to algal cells to form hetero-aggregates, altering both particle behavior and algal physiology.
The combined toxicity influence of microplastics and nonylphenol on microalgae Chlorella pyrenoidosa
Researchers examined the combined toxicity of nonylphenol and several types of microplastics on the freshwater microalgae Chlorella pyrenoidosa. The study found that microplastics of different polymer types and sizes interacted with nonylphenol in complex ways, affecting algal growth, chlorophyll fluorescence, and antioxidant enzyme activity, demonstrating that co-exposure to microplastics and organic pollutants can produce combined toxic effects.
Proteomic insights into composition-dependent effects of microplastics on freshwater microalgae Chlamydomonas reinhardtii
Researchers used proteomic analysis to study how different types of microplastics affect freshwater green algae at the molecular level. They found that the chemical composition of microplastics influences which cellular pathways are disrupted. The study provides new insights into the specific molecular mechanisms behind microplastic toxicity in aquatic organisms.
Interactions between microplastics, model pesticides and microalgae in wastewater
Researchers investigated interactions between microplastics, model pesticides, and microalgae in wastewater treatment systems, examining how the co-presence of microplastic particles and pesticide contaminants affects the efficiency of microalgae-based treatment for removing nitrogen and phosphorus from wastewater intended for agricultural reuse.
