  1. Hello. This is
  2. um a video presentation. My name is V tran.
  3. Uh The presentation is going to be about micro plastic pollution.
  4. So what is it about?
  5. Uh It's gonna be including two sources. One is a new article
  6. by independent digital news and media
  7. of microplastics in air that spiral the glow of pollution study finds.
  8. And the other one is going to be primary literature
  9. from a science to figure research
  10. of constraining the atmospheric limb of the plastic cycle.
  11. So what is plastic? Um plastic search it? We use them in
  12. they are daily lives like straws
  13. cups like Starbucks, cups that we get from Starbucks
  14. literally anything
  15. that we can think of.
  16. Um it's a resilience and synthetic nature.
  17. Most of the waste plastics are recycled,
  18. buried in landfills or incinerated
  19. But 12% into 18
  20. adequate management
  21. and littering which is
  22. not good. And um since they do not decompose recompose
  23. the leftover plastic and then be
  24. breakdown
  25. continuously.
  26. Break down into smaller synthetic polymers which are called microplastics.
  27. So from the new story they stated that plastic
  28. particles in the air has been traveling across the continent
  29. by when and can also be
  30. travel by waves in the oceans.
  31. Um
  32. 220,000 metric tons
  33. of micro plastic per year are produced.
  34. Most of them are disposed of incineration but
  35. As stated before 18% still enters the atmosphere.
  36. The atmospheric data was collected across the Western US from 2017 to 2019.
  37. Most of the
  38. plastic were from car tires and road the particles into the air
  39. microplastics splintering Friuli
  40. from like the contact
  41. of the both services
  42. with the traffic
  43. and the addition of damaged fuel emissions.
  44. The
  45. News article also mentioned about a report
  46. from the World Health Organization in 2019
  47. concluded that there were micro plastic particles
  48. in drinking water which may have negative
  49. affect and unknown consequences
  50. that can affect the ecosystem overall and the human health.
  51. Um,
  52. the inhalation of particles like microplastics can be irritating to lung tissues.
  53. 3, 2 more serious disease
  54. that relate to respiration.
  55. So about the primary literature. Scientifically
  56. the mismanagement breaking that waste can have an effect on bio chill
  57. chemical cycle as stated before. Cars and roads
  58. is mainly the thing that create most of the plastic
  59. and then
  60. marine
  61. environment and agriculture and the leases does submissions.
  62. Ah the array of increased plastic pollution is around 4% per year.
  63. And they,
  64. the scientist
  65. use the method of using observations of
  66. microplastics position and the optimal estimation techniques
  67. to determine the
  68. to determine the likely resource,
  69. the sources of microplastics.
  70. Mm hmm.
  71. So this is the data that they collected um,
  72. is representation of the major sources of microplastics to the atmosphere.
  73. Uh, as you can see the atmosphere of microplastics resources.
  74. Yeah,
  75. they have many areas that
  76. include the microplastics
  77. right
  78. Sea spray which is 11
  79. Thus near urban centers. 0.4
  80. they have a different range of um
  81. percentage.
  82. So the position of the microplastics for 84% from Rhodes,
  83. which is um, how what the news article
  84. talked about how they all can
  85. contact being contact between the tires
  86. in the road,
  87. The
  88. making contact with the traffic,
  89. causing a lot of splintering of micro plastic to the atmosphere,
  90. 1% from sea spray
  91. and 5% from agriculture, mostly from statistics
  92. fertilization. Because they
  93. used
  94. um plastic and nitrogen help the tree grow
  95. and 0.4% from the us that
  96. near the population centers like um carbon footprint.
  97. Yeah,
  98. burning fuels.
  99. Um So the data in the graph pretty much explained
  100. and this is the reference of
  101. all the pictures uh included
  102. the new articles. And this is the course of bio 1 82 General Biology
  103. for Nature's
  104. Um at Arizona State University in the spring 2022 semesters.
