Organic additive release from plastic to seawater is lower under deep-sea conditions

V. Fauvelle, M. Garel, et al.

Discover how deep-sea conditions impact the release of organic additives from plastics. This research reveals fascinating interactions between hydrostatic pressure, microbial activity, and the efficiency of additive leaching, conducted by authors from Aix-Marseille University and other esteemed institutions.

Abstract
Plastic pollution affects the entire marine environment. This study investigates the release of organic additives from polyethylene and polyvinylchloride plastics under deep-sea conditions. Results show that increasing hydrostatic pressure inhibits leaching of heavier organic additives, while deep-sea and surface marine prokaryotes promote additive release. Surface waters exhibit more efficient additive release than deep seawater.
