Abstract
An increase in global plastic manufacturing and subsequent disposal has resulted in widespread increase in microplastic pollution. Particularly, the post-COVID surge in face mask usage has introduced significant volumes of synthetic plastic microfibers into the environment, posing new ecological risks. Present study examines the toxicological impacts of face mask derived microfibers on Artemia salina, a key marine zooplankton species, using the Box-Behnken design to assess the effects of microfiber dosage (0.1 mg/L- 5 mg/L), salinity (0.5 ppt–30 ppt), temperature (10 °C-45 °C), and cyst stocking density (10 cysts/L-100 cysts/L) on hatching efficiency and swimming competencies. Results demonstrated that higher microfiber dosages (2.5 mg/L-5 mg/L) significantly reduced the hatching efficiencies and swimming competencies, while temperature and cyst density also modulated these effects. Additionally, survival assays indicated a significant reduction in survival rates with increasing microfiber concentrations, attributed to the bioaccumulation, oxidative stress and developmental deformities in the organism. The study further explores the leaching of chromophoric dissolved organic matter and turbidity, revealing a direct correlation with microfiber dosage and exposure duration. These findings underscore the urgent need for mitigation strategies to address microfiber pollution and protect aquatic ecosystems. Data presented from the research provides valuable insights into the environmental impacts of plastic microfiber contamination, emphasizing the necessity for continued investigation into effective solutions for managing plastic waste.
