It is an amazing product actually… plastic. It can be molded into all sorts of shapes and forms. In some cases, it can be more durable than other products, it is lighter and cheaper than many. Slowly over time, we began to use more and more of it. I remember as a kid in the ‘60s Tupperware products were common. Cups and bowls with resealable lids. Coffee cups followed, then 2-Liter coke bottles, to the common water bottle we see today. As I look around the room, I am in right now there are plastic pens, picture frames, suntan lotion bottles, power cords, rain jacket, the cover and keyboard of this laptop. Plastic is part of our lives.

Unfortunately, being relatively inexpensive, it is also easily disposed of. Many forms of plastic are one-time use. In some cases, we purchase and discard them without really using them – plastic wrap covering fruit, or the famous plastic grocery bags. Most of this discarded plastic eventually finds its way into the environment. Data from the 2017 International Coastal Clean Up, showed that globally all the top 10 items collected were plastic. Most of it was cigarette butts and items related to food and drink. Even with all the press, the number of plastic grocery bags collected actually increased. One study conducted in 2015 estimated the amount of plastic in our oceans would be enough to fill 5 plastic grocery bags for each foot of shoreline of the 192 countries they surveyed.
There is a lot of plastic out there. One researcher commented… it’s all still there. Some have estimated that plastic takes about 600 years to completely break down. Plastic items degrade while exposed to sun, sand, and saltwater. But they never go away. They become smaller and smaller to a point where you cannot even see them anymore – these are called MICROPLASTICS.
Microplastics are defined as any plastic items 5mm or smaller in diameter. Most plastics float, and most microplastics float as well, but pieces of microplastics have been found throughout the water column and even in the deep-sea sediments. They come in two forms; primary and secondary.

Primary microplastics are plastics that are produced at these small sizes. All plastic products begin as small beads called nurdles. Nurdles are produced and shipped to manufacturing centers where they are melted down and placed into forms which produce car bumpers, notebook covers, and water bottles. Many of these nurdles are shipped via containers and spills occur. Other primary microplastics are microbeads. These are used in shampoo, toothpaste, and other products to make them sparkle, or add color. As they are washed down our sinks and showers, they eventually make their way into the environment. Sewage treatment facilities are designed to remove them.
Secondary microplastics are those they were originally macroplastics and have been broken down by the elements. Plastic fragments and fibers are two of the more common forms of secondary microplastics. These micro-fibers make up 70-80% of the microplastics volunteers find in Florida waters. Many of these fibers come from our clothing, from cigarette butts, and other sources.
Are these microplastics causing a problem?
It is hard to say whether they have caused the decline in populations of any group of marine organisms, but we do know they are absorbing them. Studies have found microscopic plankton have ingested them, and some have ceased to feed until they pass them, if they do pass them. There has been concerned with the leaching of certain products in plastic to make them more flexible in bottled water. These products have been found in both plankton and in whales.

Another problem are the toxic compounds already in seawater. Compounds such as PCBs, PAHs, and DDT. It has been found that these compounds adhere to microplastics. Thus, if marine organisms consume (or accidentally ingest) these microplastics, the concentrations of these toxins are higher than they would be if the microplastics were not present.
Studies have shown:
– Pacific oysters had decreased egg production and sperm motility, fewer larvae survived, and the survivors grew more slowly than those in the control population.
– Plastic leachate impaired development of brown mussel larvae.
– Shore crabs fed microplastics consumed less food over time.
A recent summer research project at the University of West Florida found microplastics within the gut and tissues of all seafood products purchased in local seafood markets. And recently a study of human stool samples from volunteers in Europe and Japan found microplastics in us. Again, we are not sure of the impact on our health from this, but they are there.
So, what do we do?
One idea is to remove these microplastics from the ocean – skimming or filtering somehow. As you might guess, this also removes much needed phytoplankton and zooplankton.
There is the ole “Recycle, Reuse, Reduce” idea we learned when we were in school. Unfortunately, recycling plastic has not been working well. Being a petroleum product, the price of oil can dictate the price of recycled plastic. With low oil prices comes low recycling profits. In many cases it can be cheaper to produce and purchase new plastic products. Also, unlike glass, plastic can only be recycled so many times.

Reuse and reduce may be the better options. If you must purchase plastic items, try to reuse them. In many cases this is difficult and the reduce method is the better option. Reduce the purchase of plastic items such as your own drinking container instead of using the one-time plastic cup at meetings or events. And of course, reusable grocery bags. You will have to think on how to reduce some items, but most can be done.
For almost 40 years, the Ocean Conservancy has held the International Coastal Cleanup in September. Across the planet hundreds of thousands of volunteers clean marine debris from their shorelines. The data collected is used by local agencies to manage this problem; such as discontinuing the use of pull tops from aluminum cans. In the last couple of years researchers are trying to make the public aware of another form of plastic most know little about – microplastics.

Microplastics are defined as pieces measuring 5 mm in length or smaller. These can be large pieces of common plastics that been degraded by sea and sun. They can be small pellets called nurdles that are melted down and poured into molds to produce common plastic products or used to stuff toys. They can also be small beads used as fillers in personal care products, such as toothpaste. Those that are manufactured at this size are called primary microplastics; those that degrade to this size are secondary microplastics.
How Do They Find Their Way to Local Waterways?
The sources of secondary microplastics is obvious. We either intentional or unintentionally discard our waste into the environment. According to data collected by the local nonprofit group Ocean Hour, cigarette butts are the number item collected during weekly cleanups. Many are not aware that much of the material in a cigarette butt is actually plastic fibers, and many butts are tossed to the ground intentionally. Adhered to these fibers are the products of smoke we are concerned with in our own health – tar, nicotine, and ethylphenol.
Ocean Hours data show other forms of plastics (bags, wrappers, cups, bottles, and caps) are very common. These items are discarded directly, or indirectly, into the environment and eventually end up in our bays and oceans – “all drains lead to sea kid”. Here they are eventually broken down. Some scientists believe all the plastic ever produced is still in the sea, continuing to breakdown smaller but never really going away. I viewed a webinar within the last year where a researcher from the west coast was discussing the “great plastic island” in the Pacific. She showed a photo from the location and you did not really see a lot of large plastic drifting. However, a plankton tow revealed large amounts of microplastics.

Less common are the primary microplastics… but they are there. According to our monitoring in the Pensacola Bay Area, they make up about 20% of the microplastics found. When we wash our faces, or brush our teeth, with plastic filled products these microplastics are washed down the drain to the local sewer treatment facility. Here they remain on the surface of the water that is being treated and are eventually discharged into wetlands, or directly into a water body.
Are These Microplastics Having a Negative Impact on the Environment?
Locally, we are monitoring 22 stations. We are finding an average of 9 pieces of microplastic / 100ml of sample (little more than 3 ounces). This equates to a lot of microplastic in our bay. Science does know that these are small enough to be swallowed by zooplankton in our water column. It plugs their digestive tract and gives them the sensation of being full. Thus, they stop eating and starve. A decline zooplankton, a key component of most aquatic food chains, could affect economically important members higher up the food chain.
Laboratory studies show it may be affecting lower on the food web. When subjected to water containing microplastics, the microalgae Chorella reduced its uptake of carbon dioxide; thus reducing photosynthesis.
In larger species, microplastics have been found in the tissue of some bivalves, including those commercially harvested for human consumption. There is little evidence connecting health related problems of either the bivalve or the human consumer, to microplastic consumption – but there is concern.
There is evidence showing chemical contaminants adhere to the plastics and can increase their concentrations 1 million times. Swallowing plastics with high concentrations of Polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and DDT (all of which have been found on microplastics) could be problematic.
There is also concern of bioaccumulation of these contaminants as they move through the food chain, but little evidence that it does. There is also little research on the leaching of toxic products from these plastics and their impacts. In his recent publication on the status of water quality in Pensacola Bay, Dr. Mike Lewis agrees that more attention needs to be paid to microplastics.

What Can We Do About the Microplastic Issue?
Cut back on your use of plastics. Easier said than done, our world is full of plastic, but there are a few things you can do:
a) choose not to use straws when eating out.
b) purchase a good water bottle and take it with you. Many locations where we purchase coffee or fountain drinks you can use this bottle instead of their foam or plastic cups.
Change your habits and product choices.
Personal care products with microplastics will have polyethylene on the ingredient label; if it does – choose a different one. There is a website that lists many of these products.
If possible, wear clothing made of natural fibers.
Being aware of the microplastic problem is the first step in correcting it.
