Microplastics: A Hidden Crisis Beneath the Surface

Prompt

🧪 Poster Title Suggestion “Microplastics: Tiny Particles, Massive Impact” (or come up with your own creative title!) 🖼️ Suggested Layout (Landscape Asymmetric for visual flow) Divide the slide into columns or blocks, each with a heading and relevant visuals. 🔬 Sections & Suggested Content for Each 🧾 1. Chemical Formula / Types of Microplastics Not one specific formula—microplastics are fragments of larger plastics like: Polyethylene (PE) Polypropylene (PP) Polystyrene (PS) Polyethylene terephthalate (PET) Add images of common plastic polymers with chemical structures. 🏭 2. How Microplastics Enter the Environment Sources: Degradation of larger plastic waste Microbeads from cosmetics & personal care products (e.g., exfoliants, toothpaste) Synthetic fibers from washing clothes Industrial processes Visual idea: flowchart from “Source → Drain → Ocean” ☣️ 3. Toxicology & Ecological Impact Absorb other harmful chemicals (e.g., pesticides, heavy metals) Ingested by aquatic life → enter the food chain Block digestive tracts of marine animals Reduce reproductive health in fish, birds, and mammals ♻️ 4. Can Microplastics Be Recycled? Not directly recyclable due to small size and contamination Hard to filter from wastewater or natural systems Prevention is more effective than trying to recycle ⏳ 5. Degradation & Transformation Microplastics do not fully degrade Persist for hundreds of years Can break down into nanoplastics → even more difficult to detect and remove May release additives like phthalates or BPA ✅ 6. Possible Substitutes or Solutions Biodegradable materials (PLA - polylactic acid) Natural alternatives (e.g., coconut husk, bamboo) Bans on single-use plastics & microbeads Improved waste treatment and filtration systems 🧍‍♀️🐟 7. Human & Animal Health Impact Ingested via seafood, drinking water, air Potential effects: Hormonal disruptions (endocrine system) Cellular stress Inflammation Still under research but concerning Visual idea: cross-section of a human body with labels 📚 8.
