What makes this situation even more perilous is what plastic polymers attract. “As these fragments float around,” says Moore, “they accumulate the poisons we manufacture that are not water soluble. It turns out that plastic polymers are sponges for DDT, PCBs, and nonylphenols—oily toxics that don’t dissolve in seawater. Plastic pellets have been found to accumulate up to one million times the level of these poisons that are floating in the water itself…. Hormone receptors cannot distinguish these toxics from the natural estrogenic hormone, estradiol…our worst pollutants are being ingested by the most efficient natural vacuum cleaners nature ever invented [plankton]…. These organisms are in turn eaten by fish and then, in many cases, by humans. The whole issue of hormone disruption is becoming one of, if not the biggest, environmental issues of the twenty-first century.”
