Well, Md Imran Shah, an example of the negative impact of antifouling paints on marine ecosystems is the case of imposex in marine gastropods.
Tributyltin (TBT) is an organometalic compound added to vessel paints as an antifouling. TBT is able to induce the development of male sexual characteristics in females of marine gastropods, including penis development. This is a big problem because the development of a penis in female gastropods over time obstructs the access to the genital gland by male gametes, thus preventing reproduction.
An example of a research article which addresses this problem is this:
Ruiz, J.M; Carro; B.; Albaina, N.; Couceiro, L.; Míguez, A.; Quintela, M.; Barreiro, R. (2017). Bi-species imposex monitoring in Galicia (NW Spain) shows contrasting achievement of the OSPAR Ecological Quality Objective for TBT. Marine Pollution Bulletin 114 (2):715-723.
