did you just eat a plastic bag? how plastic pollution has entered our food chain
This article will take you on a possible journey from plastic bags to the ocean and return to your plate with a fish that may be fed in plastic bags.
Did our pursuit of the convenience of throwing away plastic lead to contaminated fish?
What about disposable plastic products?
Unlike paper, glass, and metal that is perfect for recycling, plastic almost always makes
Limited use from factory to landfill or environmental pollution.
The US Environmental Protection Agency reported the following data on plastic products in the US urban waste logistics on 2008 alone: 1.
Plastic Board and plastic cup: 780,000 tons of production, 780,000 tons of scrap. 2.
Plastic garbage bags: 930,000 tons are produced and 930,000 are discarded. 3.
Plastic bags, sacks and bags: 3,960,000 tons of production. 9.
Recover 8% (390,000).
3,570,000 tons were discarded. 4. \"Other\" non-
Durable goods including plastic disposable diapers, footwear and clothing: 4,810,000 tons were produced and 4,810,000 tons were discarded. 5.
PET bottle cans: 2,680,000 tons, 27.
Recycling 2% (730,000 tons)
1,950,000 tons were discarded. 6. HDPE (
White translucent bottle)
Production of 750,000 tons, 29. 3 % (220,000 tons)were recovered.
530,000 tons were discarded. 7.
\"Other plastic packaging\" including paint, cap, flap, egg box, production basket, tray, shape and loose filling: 3,720,000 tons were produced. 3% (110,000 tons)
In recovery 3 million 610,000 tons.
From this data, you can see that your plastic bags have more than 90% chance of becoming waste instead of being recycled.
The means of recycling are excluded from waste logistics in order to be used again.
Why don\'t my plastic bags be recycled?
Metal, glass and paper can be returned in the same form, so new materials are not required.
Recycled plastics are usually recycled down into less pure products for many reasons, such as fillers, including the olive properties of the plastic (
They attract oil, so they are often contaminated with food or other things that contain grease)
The different melting points of different plastics make the separation of plastic essential, while many products are a mixture of different plastics with different melting points.
Many plastic products are not recycled. -
Such as plastic garbage bags, plastic personal products, plastic razors mixed with plastic and metal.
Some plastics, such as plastic grocery bags, are too light to be recycled for their cheap raw materials.
Many plastic bags are contaminated with food or other waste.
Plastic bags are also notorious for clogging the recycling center equipment, another reason why they will not be recycled even if they are sent to the recycling center.
Many of the potential recyclable plastics are sent to China as waste, where burning releases toxins into the air that settle in the ocean like mercury from coal burning.
As a result, the effort to \"recycle\" plastic does not stop the need for original petrochemical products for new plastic products.
This means that we are producing more and more disposable plastics that are a one-way trip to the wasteland.
Like my plastic bag, where did the discarded plastic go?
Entering landfill sites and the environment (
Through garbage, open-air garbage dumps, waste incineration, waste container overflow, loss of waste transportation, loss of waste facilities, etc. . . )
The world\'s largest pile of plastic is now the ocean.
Plastic bags, also known as urban wind-rolling grass or plastic wind socks, are easy to travel with air and water flowing into the ocean.
This is a report from the California plastic debris action plan: \"The number of plastics in the world of marine waters --
Width is increasing significantly.
In the South Atlantic, the number of debris increased by 100-
Folded in early 1990.
In the coastal areas of Japan from 1970 to 1980, marine plastics-
Particle density is increased tenfold every ten years.
However, in 1990 seconds, the density seems to increase tenfold every two times. three years.
Over the past decade, microplastics in the North Pacific have tripled.
Researchers at the University of Plymouth (UK)
Particles with a diameter of less than 20 microns are now common in marine sediment and water columns.
They also show that the number of such debris has increased significantly over the past 40 years.
A series of common polymers have been identified, indicating that microscopic particles may be formed by the decomposition of larger substances.
Their conclusion is that their \"findings indicate a wide range of space and accumulation of such pollution.
Given the rapid increase in plastic production, the life of the plastic and the disposable nature of the plastic product, this contamination may increase.
The environmental consequences of these fragments are not clear, but when they are kept in the aquarium (detritivores), lugworms (Deposit feeder)
Pot and rattan (filter feeders)
Within a few days, all the tiny particles taken in.
\"Data is not limited to the laboratory.
Marcus Eriksson and Anna Cummins collected samples from Gyre in the North Pacific during 2008 trips across the North Pacific 4,000 miles of the algarita Marine Research Foundation.
During this voyage, Algalita MRF recorded a doubling of the density of plastic particles since Moore first published the findings in 1999, as well as new evidence of the intake of plastic by lantern fish.
The small fish only surface at night to feed on plankton, which ingest plastic particles floating on the surface of the ocean.
Of the 671 Algalita MRF fish collected during night fishing, 35% had plastic particles in their stomach.
Record holder, a 2.
The 5 inch-long lantern fish consumed 84 pieces of plastic.
These lantern fish, which account for 50% of the biomass of marine fish, are the primary source of food for salmon, tuna, hi fish and other fish commonly eaten by humans, raising an obvious question: do the chemicals in plastic get into our sushi?
Plastic has become part of the marine food chain, what does that mean?
Like mercury in coal
Burning plants enter our food chain through ariel deposits, and plastics and all the chemicals that make them and attach to them are also entering our food chain because they are consumed by marine life.
In addition to chemicals such as BPA and neighboring benzene ester, which are used as petroleum-based additives for plastics, plastics are olife (attract oil)
, Absorb oily toxins from the surrounding water (
Such as PCBs, partially burned hydrocarbons, such as oil drops on cars, pesticides, such as DDT)
The accumulation concentration of toxins is 1 million times higher than that in the surrounding seawater.
Algalita MRF has recorded our plastic waste as well as its concentrated toxins and has entered our food chain.
This means that we are poisoning fish with our toxic waste, an important source of protein.
The next time you go to the market, using canvas bags is good for the environment, and it is also good to exclude toxins from fish meals.
