Plastic has consistently
comprised a majority of the litter found on the beaches of New Jersey. In 2015,
Clean Ocean Action’s Beach Sweep data quantified the amount of plastic present
on beaches as approximately 71.6% of the total litter collected. Why are
plastics such an issue for our waterways? The main issue is that plastics do
not biodegrade, instead they photodegrade into smaller and smaller
pieces. Microplastics are plastic pieces smaller than 5 mm and are of
particular concern because of the threat they pose to marine life, who often
mistakes these plastic particles for food. The primary source of microplastics originates
from personal care products such as facial scrubs and toothpastes. Other
sources include larger plastics that have photodegraded and microfibers that
are the result of washing clothing made of synthetic materials. Due to their
small size, microplastic pieces bypass wastewater treatment plant filters and
are discharged into our waterways.
Microplastic pollution is
currently at the forefront of international concern because of the threat it
poses to marine life and, consequently, human life. Marine organisms that
comprise the base of the marine food web (zooplankton and phytoplankton) ingest
these particles. Since these plastics cannot be digested they travel up the
food chain. This is where the danger for humans arises. Microplastics are
hotbeds for the accumulation of toxins. What may start out as a small
concentration biomagnifies as it travels up the food chain because larger organisms
need to consume larger amounts of food. The seafood lover’s menu has the
potential to be laden with toxins as a result of microplastic pollution.
A major victory for our
ocean occurred in 2015 when President Obama signed the “Microbead-Free Waters Act,”
which bans the manufacture of microbeads in July 2017. Until then, it is
important to be an informed consumer and avoid products that still contain
microbeads. When purchasing products, look for and avoid the ingredients
polyethylene, polypropylene, polyethylene terephthalate, polymethyl, methacrylate,
nylon and polylactic acid. Try using exfoliants with natural ingredients such
as coffee, cocoa, apricot seeds, sugar and salt.
As the Marine Debris intern
at Clean Ocean Action I am working alongside staff members to help better
understand and promote the issues of microplastic pollution in our waterways. Clean
Ocean Action is working with students from the Marine Academy of Science and
Technology as well as scientists from NOAA on a microplastics research project
that will quantify the amount of microplastics present in the New York-New
Jersey area. Sand and water samples taken along the coast are being analyzed
using pre-tested research methods. Another essential component of the
microplastics program is public outreach. Part of my job is assisting with
Corporate Beach Sweeps, where we highlight the issues of microplastic pollution
to volunteers. A social media campaign in conjunction with the US EPA’s Trash
Free Waters initiative was launched the week of World Oceans’ Day
(6/6/2016-6/12/16). Throughout Microplastics Awareness Week, Clean Ocean Action
is educating the public on these issues via social media. Join us and promote a
clean ocean! Share our infographics and posts with your friends and family.
Together we can create trash free waters!
