Abstract One of the main challenges that face the environment today is the threat of plastic materials in the environment. All forms and sizes of plastic are harmful to the environment; this paper looks at the effects of microplastics which are small forms of plastic that are at least 5mm in size. Due to their small size, the microplastics end up being ingested into the bodies of aquatic animals causing health consequences that are uncertain to the organisms. This review focuses on the susceptibility of marine organisms to the physical, chemical and biological uptake of microplastics. Key words: microplastics, aquatic organisms, marine life Effects of Microplastics on Marine Organisms Introduction One of the most dangerous environmental problems …show more content…
When the plastics enter into the oceans, some young fish are drawn to them, and seem to think that it is food, and they end up preferring the plastic to their natural food sources which eventually starves them before they can reach their reproductive age. The microplastics have been found in the bodies of whales, seabirds, and fish. Marine organisms ingest the particles, but they are unable to digest them, this leads to a buildup in the digestive tracts of the animals which hinders the microorganisms from taking in more food, and it diminishes the organisms feeding stimulus which can lead to starvation (Fossi, M. C, 2014). Studies have proved that the physiological consequences of crabs taking up polystyrene microspheres through their gills are minimal. When the crabs inhale polystyrene microspheres into their gills chambers, it leads to a small but temporary change in ion regulation and oxygen …show more content…
An example of an additive is di-butyl phthalate and biphenyl A (BPA), these substances are incorporated while the plastics are being manufactured to provide tensile flexibility and tensile strength. The microplastics tend to accumulate and adsorb toxic materials from the seawater around them, such as organic pollutants and heavy metals. The chemicals are not bound to the microplastic surface, and as a result, when ingested they tend to leach into the animal tissues (Do Sul, J. A. I, 2014). The impacts from such chemical leaches include hepatic stress in fish, mortality, and endocrine
The theme in a Plastic: A Toxic Love Story and " A Dirge" are both on polluting water with plastic. You should not pollute the water with plastic because it could damage the animals in the water.
Which means their obviously bad for the aquatic marine life environment & are cause many different forms of damage for them & us as one. On p.g. 23 of The New York Times upfront magazine “Birds,fish, sea turtles, & others are getting tangled in plastic bags or mistake them for food & choke”. Someone else might argue that they could the plastic bags in landfills instead of oceans. But that counter- argument is flawed because you’re just polluting by burning plastic which is bad on our part we’re not doing our part to support & taking care of the earth. Plastic in the ocean isn't just bad for plants & animals but for humans too because of the food chain some of us eat animals as a meat source such as aqua marine life like fish. If the fishermen catch fish that have been eating plastic then it's in our food supply if we eat that fish it's gonna be bad for us so many will end up getting sick from the plastic inside of the fish then what will we do our aqua marine food supply will go down the drain we couldn’t eat the fish since it's basically contaminated with plastic that we’re dumping there instead of trying to fix it & getting rid of plastic bags for good for the good of the earth. We’re causing damage towards the earth by dumping all that plastic into the ocean which damages our water supply it’ll poison us although we clean the water it depends on how big the plastic particles are, it’ll make us sick & sense it’s been lying in the oceans could bring in new pathogens &
The plastic apocalypse is upon us. Our oceans are currently burdened by massive expanses of floating plastic products and shreds extending farther than the eye can see in multiple locations. The biggest of these, located in the North Pacific Ocean,1 is known by many as the Great Pacific Garbage Patch. This dangerous collection of trash is surrounded by the North Pacific Subtropical Gyre,1 or a series of circling currents located in the Southern Hemisphere that carry plastics and other slow-degrading garbage and trap them inside its bounds.2 This specific Garbage Patch stretches from North America to Japan and the plastic-to-water ratio varies throughout.1 Because of this phenomenon, plastic is being distributed throughout oceans and deposited
Phthalates are found in plastic materials. They can cause endocrine disruption, in other words it can affect our hormones. They can also cause damage in the environment. It can harm marine life since we don’t properly recycle throw away plastic materials. PFOA (perfluoroctanoic acid) is a carcinogen. Studies show that it can cause pancreatic canc...
Humans encounter harmful chemicals every day, but it is generally unexpected by the public that products that they use every day, such as water bottles and metal cans, contain ingredients that can pose a threat to their health. Bisphenol A (BPA) is a compound that is widely used during the manufacturing of epoxy resins that provide a protective layer to many food containers, as well as hard, clear plastics (Staples, 1998). BPA leaches from these containers into the food or drink that humans consume on a daily basis (Krishnan, 1993). Several studies have found traces of BPA in over 90% of adult participants, and 99% of school-age children (Calafat, 2008). The chemical is still being used in modern times, despite the research that advises otherwise. Bisphenol A is a dangerous chemical that causes various chronic health problems, such as cancer, as well as sexual abnormalities in both males and females.
Everyday millions of Americans come in contact with many different forms of plastics and think nothing about it. Whether its drinking from water bottles purchased at your local super market to eating leftovers from food storage containers in your refrigerator, plastics are everywhere in the world and it seems as if they’re here to stay. But have you heard of the chemical Bisphernol-A? Also known as BPA, this chemical compound is found in just about every plastic that you come in contact with and has created quite the uproar in the media over the last several years in question on its safety for consumer use. Scientists from around the world believe that BPA is the cause of many adverse health effects found in infants and adults, but the scientists aren’t the only ones voicing their opinions on the subject. Many concerned consumers in light of recent studies on the controversial BPA chemical are worried about what they themselves and their families are ingesting and exactly how it is affecting them. This problem amongst consumers has been so great that many companies such as Wal-Mart have demanded the removal of baby and infant products that contain the controversial chemical BPA from their store shelves.
According to a study conducted by the University of British Columbia, approximately “93 percent of beach fulmars (migratory seabirds related to the albatross) had bellies full of plastic, with one even having upwards of “454 pieces of plastic in its stomach” alone. (Source B) Similarly, in a 2011 International Coastal Clean-up, there were 964244 plastic bags found in the ocean, each having the potential to kill wildlife (Source C). A major reason as to why plastic bags are so hazardous to animal health is the fact that they have no biodegradable capabilities, meaning that instead breaking down into organic materials, plastic takes 500 to 1000 years to simply photodegrade, fragmenting into smaller pieces but not presenting any less danger (Source F). As these pieces become smaller, making it easier for any animal life, marine or not, to ingest it and suffocate as a result of the blockage. This is when the implementation of a tax on plastic bags could become extremely useful as a method of regulation and
Recently, an uninhabited island in the South Pacific Ocean was found to be polluted with 38 million pieces of plastic that had been carried over by currents (Wang, “No one lives on this remote Pacific island”). The island, dubbed ‘trash island’, is home to diverse animal populations that have all been devastated by the pollution. On the beach, hundreds of birds were seen dead by reporters and scientists. When analyzed, the primary cause of death turned out to be consumption of plastic. When animals ingest plastic, it clogs their stomach and poisons their body with toxic chemicals. These toxic chemicals cause an array of issues, such as reproductive and endocrine problems. Eventually, this leads to death (Knoblauch, “The environmental toll of plastics”). But due to the nature of plastics, it can take hundreds or even thousands of years to completely degrade, meaning that as plastic pollution continues to build up, more places like ‘trash island’ will be discovered. According to conservation scientist Alex Bond, “…[The island] is just an indicator of what’s floating around out there” (Wang, “No one lives on this remote Pacific
The Great Pacific Garbage Patch is the largest garbage dump in the world. According to estimates made by experts, the patch holds approximately three and a half million tons of garbage. Majority of this garbage is made of plastic. This waste is a threatening problem to the patch’s surrounding wildlife. Many animals are caught in the floating pieces of trash and it is the cause of the deaths of about one million birds and about one hundred thousand other sea animals. Due to the oceans nature and constant moving currents, the trash is also constantly moving. Therefore the size of the patch never stays the exact same. However, scientists believe it be approximately two times the size of Texas. The plastic is mostly broken down from larger materials into small pieces. The patch has been referred to as one scientist as a, “plastic soup”. This garbage poses such a threat mainly because it does not biodegrade. These plastics will be in the ocean essentially forever. Many plastics also contain chemicals, and absorb other chemicals and pollutants they become exposed to. These newly absorbed toxins are then leaked and distributed back into the ocean over time. The chemicals can directly enter the bodies of the animals which consume them. A study was being conducted by scientists of the fish that inhabit the area around the patch. What the researchers found inside the belly of one fish (that was no larger in size than that of a finger), was eighty four small fragments of plastic. It does not take scientists to recognize the impact of this problem, Zach Gold, who is sixteen, is from Santa Monica California. Zach enjoys s...
The main effect of this plastic is pollution. In passage 3 it states that ” We have so much to thank the oceans for; however, they are threatened daily by natural and manmade pollution. Ocean pollution comes in many forms, but the largest factor affecting the oceans is plastic”.
Using plastic bags are second nature to people in this day and age. Warner acknowledges, “Much to the dismay of the environmentally conscious citizens worldwide, the ubiquity of the free plastic carryout bag has bred nonchalant consumers who take this modern convenience for granted” (646). Although some people are conscious about the environment, people strive more for convenience and do not think about the impacts using bags have not only on the environment, but on themselves as well. If something is bad for the environment, it will alternatively be bad for humans as well. When plastic bags are exposed to the sun from being littered all around, the ultraviolet rays cause the substances of plastic bags to weaken. After the substances weaken, the substances become invisible to the naked eye. The substances that are no longer able to be seen are toxic to humans (Warner 649). As a result of plastic bags being littered around, animals consume plastic bags. This is negatively affects humans because animals are often consumed. When humans consume animals like, fish, there can be plastic in the fish’s belly, which then transfers to the humans and this poses a concern for human’s health. Humans are negatively affected by plastic bags because of the toxic chemicals in plastic bags, as well as, consuming animals with plastic in their
Although plastic bags appear to be fragile and light, their negative environmental effect is devastating. Plastic bags may cause large amounts of pollution in every step of their limited life cycle, from the extraction of raw materials, production, transportation, and recycling or disposal. Plastic bags can be defined as the most damaging form of environmental pollution. They can have a damaging effect on marine animals and wildlife in addition to the aesthetic effects on beaches, parks, and trees. Plastic bags are potentially one of the main causes of death to marine animals (Harbor keepers,2008). Up to one hundred thousand marine animals or more die each year from eating plastic bags which are mistaken for food. This can result in blocking the animal’s intestines and possibly lead to the animal’s death. Another possible situation is that wildlife, such as birds, can get tangled in plastic bags causing choking and immobility, which may eventually lead to death. (Senior, 2008) and (Citizen Campaign, 2010). In other situations, after plastic bags photo degrade they remain toxic and could be eaten by fish, shellfish or any other marine life and survive this allows the toxins to enter our food chain through bioaccumulation (Puget Soundkeeper Alliance, 2011).
These fragments absorb all the toxins that pollute waterways, contaminate soil, and sicken animals (which are then consumed). Plastic trash also absorbs organic pollutants such as BPA. They take centuries to decompose while sitting in landfills, amounting to billions of environmentally poisonous time bombs. Bisphenol A (BPA) is a chemical compound used to create polycarbonate plastic and epoxy resins. Polycarbonate plastics are found in a wide range of products, but food and drink containers are the most concerning.

More than fifty species of birds are known to ingest plastic. When they eat plastic, they feel full, so some of them die of starvation. Algal blooms are another thing that kills marine life. Algal blooms are sea scum, whale food, and sea sawdust. Algal blooms are bundles of fine threads, rusty brown, they have a fishy smell, and are common in August through December.
