Tóm tắt

Accidents of ships carrying diverse hazardous chemicals and plastics can lead to complex spills of pollutants in marine ecosystems. One such incident was the catastrophic fire on the container ship X-Press Pearl which sank off the Sri Lankan coast in 2021. Explosions and fire resulted in plastic pellets and burnt clumps of melted plastic and combustion residues washing ashore. In this study, we analyzed the acute toxicity of the leached chemicals from this debris on various planktonic organisms: phytoplankton (Rhodomonas salina), meroplankton (Paracentrotus lividus larvae) and holoplankton (Acartia tonsa nauplii and adults). Acute exposures were conducted with a range of leachate dilutions for 72 h. The growth of R. salina was slightly affected by the leachates. Larvae of P. lividus showed a concentration-dependent reduction in growth and normal development (EC
