Antifouling paint particles: Subject of concern?
No full textAntifouling paints have a lengthy history of environmental controversies and efforts toward developing safer formulations. However, recent attention from researchers has been directed toward the particles that detach from these paint coatings, known as antifouling paint particles (APPs). These APPs share similarities with other anthropogenic particles, such as microplastics, but exhibit distinct behaviors and comprise a more complex mixture of chemical components, including highly toxic biocides. Given the composition of APPs and their prevalence in marinas and boatyards, several environmental implications may arise. Nevertheless, field and ecotoxicological studies on this subject are still scarce. In this contribution, we examine the current state of knowledge regarding APPs and endeavor to address the following question: Should APPs be a subject of concern

Boat paint and epoxy fragments - Leading contributors of microplastic pollution in surface waters of a protected Andaman bay
No full textPlastic pollution is a growing concern even in India\u27s remotest oceanic islands. To understand the extent of the problem in relatively undisturbed areas of the Andaman and Nicobar Islands, we nested a microplastic survey within a year-long meroplankton study in the protected bay of the Lohabarrack salt water crocodile sanctuary, that lies on the less populated west coast of South Andaman Island. Surveys recovered microplastics year-round, in 299 out of 300 samples. The average microplastic density in the protected bay was 0.45 ± 0.32 particles per m3. Densities were highest during the monsoon, peaking at 2.34 particles per m3. Marine coating fragments (boat paint and epoxy, 58%) dominated the plastic debris composition year-round, while fibre only amounted to 15%. Marine coating fragments were most frequently encountered during the pre-monsoon, while fibres and other miscellaneous debris grew in abundance during the monsoon and post-monsoon months. Marine coating fragments were eaten by arrow worms, gastropods, appendicularians and Lucifer shrimp, and constituted 7% of the arrow worm diet. Microplastic density and composition found in this west facing protected bay was in stark contrast to the previously published observations from the east facing, human dominated Port Blair bay, providing clear indication of sources and potential mitigation strategies. This is the first year-long record of ocean plastics from the Andaman Islands, India and it provides evidence of pollution by boat paint and epoxy particles, an often-overlooked component of microplastic pollution
