Research on marine pollution and its impacts on biota has focused over the last 15
years on an important anthropic pollutant, plastic, and specifically on the effects of
microplastics on marine organisms. Of varied types and size, they have different origins
depending on their final use and carry chemical pollutants that can contribute to
diversification of damage in organisms exposed to these microparticles. Although we
have an extensive literature on the physical effects of microplastics on marine biota, the
chemical effects of additives and pollutants adsorbed to its structure are still poorly
known, especially in basal metazoan organisms such as sponges. Among additives with
presence in the marine ecosystem, DEHP (Di(2ethylhexyl phthalate)), a product used as
plasticizer to increase the malleability of polymers such as PVC, has the greater
concentration. Potent endocrine disruptor in vertebrates, recently DEHP was found in
sponges tissues, but there are no reports about its possible chemical effects on the
physiology of these filter-feeder organisms. This work seeks to obtain, with the use of
classical methodologies, such as histology, and modern ones, such as metagenomics, the
first reports of the effects of exposure to DEHP in the sponge Hymeniacidon Heliophila,
at different biological levels. Less...
