Researchers don’t know very much about the effects of ingesting plastic on fish or humans
. However, there is evidence that that microplastics and even smaller particles called nanoplastics can move from a fish’s stomach to its muscle tissue, which is the part that humans typically eat.
Are microplastics in fish harmful to humans?
Microplastics in wild fish from North East Atlantic Ocean and its
potential for causing neurotoxic effects, lipid oxidative damage, and human health risks associated with ingestion exposure
.
How much plastic do fish ingest?
Fish in the North Pacific ingest
12,000 to 24,000 tons of plastic each year
, which can cause intestinal injury and death and transfers plastic up the food chain to bigger fish, marine mammals and human seafood eaters.
What problems do microplastics cause?
If ingested, microplastics can
block the gastrointestinal tracts of organisms, or trick them into thinking they don’t need to eat, leading to starvation
. Many toxic chemicals can also adhere to the surface of plastic and, if ingested, contaminated microplastics could expose organisms to high concentrations of toxins.”
Are microplastics harmful?
Microplastics can carry a range of contaminants such as trace metals and some potentially harmful organic chemicals. These chemicals can leach from the plastic surface once in the body, increasing the potential for toxic effects.
Microplastics can have carcinogenic properties, meaning they potentially cause cancer
.
What happens if humans eat microplastics?
Microplastics cause damage to human cells in the laboratory at the levels known to be eaten by people via their food, a study has found. The harm included
cell death and allergic reactions
and the research is the first to show this happens at levels relevant to human exposure.
Do humans consume microplastics?
The ubiquitous exposure of humans to microplastics (MPs) through inhalation of particles in air and ingestion in dust, water, and diet is well established.
Humans are estimated to ingest tens of thousands to millions of MP particles annually, or on the order of several milligrams daily.
Do all fish contain plastic?
And even in studies that did report plastic ingestion, researchers did not find plastic in every individual fish. Across studies and species,
about one in four fish contained plastics
– a fraction that seems to be growing with time. Fish that did consume plastic typically had only one or two pieces in their stomachs.
What does plastic do to fish?
Some negative effects that scientists have discovered when fish consume plastic include
reduced activity rates and weakened schooling behavior, as well as compromised liver function
. Most distressingly for people, toxic compounds that are associated with plastic transfer to and bioaccumulate in fish tissues.
How much microplastics do humans consume?
At this rate of consumption, in a decade, we could be eating 2.5 kg (5.5 lb) in plastic, the equivalent of over two sizable pieces of plastic pipe. And
over a lifetime, we consume about 20 kg (44 lb)
of microplastic.
Why are plastics bad for humans?
These small plastic particles may harm our health once they have entered our bodies.
Plastic products contain chemical additives. A number of these chemicals have been associated with serious health problems such as hormone-related cancers, infertility and neurodevelopment disorders like ADHD and autism
.
What foods contain microplastics?
Apples and carrots
have the highest levels of microplastic particles. However, microplastics appeared in other crops such as pears, broccoli, lettuce, potatoes, radishes, and turnips. Contamination in fruit and vegetables is thought to occur when plants suck water that contains microplastics up through their roots.
Are microplastics in drinking water?
Its official –
microplastics have been found in our drinking water
. A recent study by OrbMedia analyzed 159 water samples, sourced from both tap water and bottled water in 14 countries, and found that over 80% of all samples contained tiny plastic particles, with an average of 4.34 plastic particles per liter of water.
Can your body get rid of microplastics?
Larger pieces of plastic can leave your body through elimination
but there have been cases where it is absorbed or left sitting in the stomach. Chemically. Plastics in small pieces can be absorbed into your body and poison you.
Do microplastics cross the blood brain barrier?
Several studies reported the accumulation of micro- and nanoplastics in brain tissue of fish and indications that
micro- and nanoplastics can cross the blood-brain barrier
[22, 79, 80, 86].
Do microplastics cause infertility?
Microplastic pollution is found in human organs and
scientists fear the tiny particles could increase the risk of infertility
and cancer. Microplastic pollution has been found in human organs — with scientists fearing the tiny particles could increase the risk of infertility and cancer — a study has reported.

Are microplastics endocrine disruptors?
Microplastics (MPs) and mesoplastics are able to sorb harmful substances and often contain additives, e.g., endocrine disrupting chemicals (EDCs)
, that can cause adverse effects to organisms.
Is fish from the ocean safe to eat?
Many fish in the bay and Ocean are healthy and safe to eat
, but some fish have high levels of toxins like polychlorinated biphenyls (PCBs) and mercury that can harm your health and are NOT safe to eat.
