From the shoreline at North Avenue Beach in Chicago, the blue
water of Lake Michigan stretches as far as the eye can see. But beneath
that pristine image, there's a barely visible threat, says Jennifer
Caddick of the Alliance for the Great Lakes: [toxic plastic debris in the form of] microbeads.
These
tiny bits of plastic, small scrubbing components used in hundreds of
personal care products like skin exfoliants and soap, can slip through
most water treatment systems when they wash down the drain.
Environmentalists
say they're a part of the plastic pollution found in the ocean and,
increasingly, in the Great Lakes, which contain more than 20 percent of
the world's freshwater. Now Illinois and New York state lawmakers are a
step closer to banning them.
Microbeads, says Caddick, engagement director for the Alliance, are "a bigger problem than we initially had thought."
Plastics That Look Like Food
Sherri
Mason, an associate professor of chemistry at the State University of
New York, Fredonia, sailed with a research team over the past couple of
years to collect data on the prevalence of plastics in the lakes. They
dragged a fine mesh net in the waters at half-hour intervals to snag
what they could -- "anything that's bigger than a third of a millimeter,"
Mason says.
When the boat docked at Chicago's Navy Pier last
summer, Mason showed off the sample bottles of microbeads that she and
her team had collected in Lake Michigan.
Mason says her testing
found, on average, 17,000 bits of tiny plastic items per square
kilometer in Lake Michigan. The levels were much lower in Lake Huron and
Lake Superior, but Lake Erie and Lake Ontario had much higher
concentrations.

Plastic Microbead Trash from Oceans to Great Lakes Hurting Birds, Marine Life — and Humans?
“We can show that the chemicals are adhering to the plastic. We can show that organisms eat the plastic. We can show the chemicals then desorb into the organism that affects the health of THAT organism!” - Associate Prof. of Chemistry Sherri Mason, SUNY, Fredonia
