Particulate matter and nanoplastics: synergistic impact on Artemia salina
AI summary Read the abstract
Combining nanoplastics with particulate matter (airborne or aquatic fine particles) produces worse outcomes for the brine shrimp Artemia salina than either pollutant alone, reducing survival and vitality. This synergistic toxicity is important because in real environments, nanoplastics rarely exist in isolation — they co-occur with other pollutants, making risk assessments based on single-contaminant studies likely to underestimate harm.
Investigates the synergistic impacts of particulate matter and nanoplastics on the vitality and longevity of Artemia salina , emphasizing the potential implications for environmental sustainability and ecological balance.

Ecotoxicity of emerging pollutants: Interactive impact of polystyrene nanoplastics and Metanil yellow on Artemia salina
AI summary Read the abstract
Researchers exposed a common marine test animal, brine shrimp, to polystyrene nanoplastics combined with a synthetic yellow dye and found the mixture was far more toxic than either substance alone, killing over 93% of shrimp. The dye coated the nanoplastic surfaces, increased particle size, and amplified oxidative stress, showing that nanoplastics can make co-existing pollutants more dangerous.
Synergistic impact of nanoplastics and nanopesticides on Artemia salina and toxicity analysis
AI summary Read the abstract
Researchers studied how polystyrene nanoplastics interact with nanopermethrin, a nano-sized pesticide, and their combined toxic effects on brine shrimp. The study found that nanoplastics acted as carriers for the pesticide, and the combination was significantly more toxic than either substance alone, lowering the lethal concentration from 4.5 to 3.1 mg per liter. These findings suggest that nanoplastics in the environment can amplify the harmful effects of pesticides on aquatic organisms.
A combined toxicological impact on Artemia salina caused by the presence of dust particles, microplastics from cosmetics, and paracetamol
AI summary Read the abstract
Researchers exposed brine shrimp to a combination of dust particles, cosmetic microplastics, and paracetamol to study their combined toxicity. The findings indicate that multiple pollutants together caused greater harm than any single pollutant alone, reducing hatching rates, survival, and antioxidant defenses, which highlights how real-world mixtures of contaminants can amplify damage to aquatic life.
Toxicity of polystyrene nanoplastic and copper oxide nanoparticle in Artemia salina: Single and combined effects on stress responses
AI summary Read the abstract
Researchers tested polystyrene nanoplastics and copper oxide nanoparticles individually and in combination in brine shrimp (Artemia salina) and found synergistic toxicity — the combined exposure caused greater growth inhibition, oxidative stress, and cholinesterase disruption than either contaminant alone.
Single and combined toxicity of amino-functionalized polystyrene nanoparticles with potassium dichromate and copper sulfate on brine shrimp Artemia franciscana larvae
AI summary Read the abstract
Researchers tested the acute toxicity of amino-functionalized polystyrene nanoplastics on brine shrimp (Artemia franciscana) larvae alone and in combination with heavy metal toxicants, finding that nanoplastics generally enhanced the toxicity of chromium and copper co-exposures, demonstrating that realistic multi-contaminant scenarios pose greater risk to zooplankton than single-chemical assessments suggest.
