Ahoy all neighborhood Lake Watchers!
Just in Time for Earth Day 2014
On April 26 at 11 am a beach clean up
will commence at the end of Brown Road in Wolcott NY, sponsored by
Adventures in the Finger Lakes, Silver Waters Sailing, and Lakeshore
Environmental Action. Plastic trash is a pervasive problem throughout
the world as we have seen during the search for the missing Malaysian
airlines' Boeing 777 . While no one ever sighted the aircraft, they
found plenty of debris and trash in one of the most remote parts of
the ocean. Some of it was big enough to see from satellites. Here on
Lake Ontario plastic trash of various sizes and types is also a
problem. In 2012 Dr. Sherri Mason, a chemistry professor at Fredonia
State U, sampled several of the Great Lakes for plastic. She found
that Erie’s surface had the highest density of any waters surveyed,
averaging somewhere around 80,000 particles of microplastic per km2.
In 2013 volunteers including Lake Shore Environmental Action members
sampled Lake Ontario for the first time for her studies with
equipment loaned by Dr. Mason (see photo above). And plenty of plastic turned up in our
lake too.
The problem with plastic in our
drinking water is that the small bits can actually attract insoluble
organic molecules through a process called adsorption. These
molecules are usually toxic, and if the plastic bit ends up in the
gut of a small fish or a waterflea or copepod, they may be taken up
by the animal and then passed up the food chain. We now know that
very small amounts of plastic can have big impacts on humans by
mimicking the action of certain natural hormones in our bodies. The
microplastics in Dr. Mason's samples came in part from the 40 plus
billion pounds of plastic bottles, bags and other trash that we toss
each year. It gets broken up and washed back off the beaches into the
lake where it floats around and sometimes gets eaten by birds or fish
or zooplankton.
Help us prevent this from happening by
doing two things. Recycle and avoid single use plastic material
whenever possible and join us at the end of Brown Road. Bring a black
and a clear trash bag. We will sort our 'treasures' for recycling as
much as possible.
