microplastics physics, chem, bio

1. Micro Plastic: Microplastics are tiny plastic particles (<5mm) that pollute the environment.

2. transportation of microplastics PART 1 3

3. Wave Smash and The Ocean's Power 5 Pounding Waves: Ocean waves crash against plastics, causing mechanical stress. Breakdown: Plastics fragment into smaller pieces, becoming microplastics . Accelerated Degradation: Wave action speeds up plastic degradation. Wave Intensity: Stronger waves increase fragmentation.

4. How Do Microplastics Get Around? 4 OCEAN EXPRESS : MICROPLASTICS RIDE OCEAN CURRENTS, TRAVELING FAR AND WIDE, MEETING MARINE LIFE FRIENDS ALONG THE WAY! WIND BLOWN : MICROPLASTICS GET SWEPT AWAY BY WIND, FLYING HIGH AND LANDING IN UNEXPECTED PLACES! SEDIMENT SHUFFLE : MICROPLASTICS GET BURIED, THEN RESURFACE, LIKE THEY'RE PLAYING HIDE-AND-SEEK IN SAND AND SOIL!

5. The Chemical Conundrum of microplastics PART 2 6

6. Plastics break down chemically, releasing toxic substances like: Bisphenol A (BPA) Phthalates Flame retardants Microplastics absorb pollutants like: Heavy metals (lead, mercury, arsenic) Persistent organic pollutants (POPs) Polycyclic aromatic hydrocarbons (PAHs) 7 Degradation Drama

7. When microplastics degrade or release absorbed pollutants, they can: Harm Marine Life : Toxic substances affect growth, reproduction, and survival. Contaminate Food Chain : Pollutants accumulate in organisms, potentially reaching humans. Pollutant Transport : Micro plastics can transfer pollutants to organisms, potentially increasing exposure. 8 The Toxic Tango

8. Tiny Troublemakers: The Biology of Microplastics ! PART 3 9

9. The Microplastic Menu Organisms ingest micro plastics, thinking they're food! Mistaken Identity: Micro plastics resemble natural food sources. Ingestion: Animals eat micro plastics, potentially harming themselves. The Bioaccumulation Buildup Micro plastics accumulate in organisms and ecosystems! Food Chain Transfer: Micro plastics move from one organism to another. Bio magnification: Micro plastic concentrations increase up the food chain. 10

10. The Biological Consequences Changes in Behavior: Microplastic exposure alters behavior, affecting survival. Reproductive Issues: Microplastics impact reproduction, potentially affecting populations. Ecosystem Disruption: Microplastics disrupt delicate ecosystem balances. 11 The Biological Consequences

11. Microplastic-Free Marvels: 6 Solutions to Save the Planet! Reduce Single-Use Plastics Improve Waste Management Implement Extended Producer Responsibility Promote Biodegradable Alternatives Clean Up Existing Pollution. Educate and Raise Awareness.
