These fine particles are now thought to act like sponges‚ concentrating pollutants such as PCBs‚ DDT and PAHs. When the particles are ingested by filter feeding sea creatures‚ they enter the food chain and ultimately into fish destined for human consumption. They also harbor unique colonies of microbes‚ but it is too early to say what impact this emerging
