While bumblebees may be exposed to microplastics (MPs), the effects on them are not well studied. Therefore, in this research, we assessed the cytotoxicity of pristine and photodegraded spray paint-derived MPs on the midgut, Malpighian tubules, and hepato-nephrocitic system cells of Bombus atratus workers exposed to 50 mg.L MPs for 96 hours.

Article Synopsis
- Fipronil (FP) is an insecticide that is effective against pests but has harmful effects on bees, particularly on the brain of bumblebees.
- A study was conducted on Bombus atratus, exposing them to two concentrations of FP for 96 hours, using techniques like the comet assay to assess DNA damage and morphological changes.
- Results indicated that FP exposure led to significant DNA damage and structural changes in the bumblebee brains, highlighting the urgent need for further research on its toxic effects on other species for better environmental risk assessments.

Eusocial bees are declining due to anthropogenic actions. Individuals can be exposed to contaminants like Cd, which have been found in pollen. Thus, we evaluated the potential genotoxicity of Cd to the hepato-nephrocitic system of Bombus atratus foraging workers exposed to environmentally safe doses of Cd (0.
