 Release of potentially invasive alien organisms.  Release of toxins which may degrade the local environment  .
In-water cleaning of structures and vessels may distribute the surface contaminants in an area where they could be harmful. There are two main concerns: Release of potentially invasive alien organisms. This is mainly a problem when the fouled surface is on a vessel which has traveled from a different ecological region, and is covered with species alien to the region where it is cleaned. Release of toxins which may degrade the local environment . This is a concern where the surface has a layer of antifouling paint under the fouling layer .
