Microplastics can carry pathogens to new points in the food chain

The video discusses the ongoing concerns about microplastics, which are small plastic particles less than 5 millimeters in diameter. These particles can originate from the breakdown of larger plastics or be added to products like cosmetics. Microplastics can harbor pathogens, forming biofilms that may carry antibiotic-resistant bacteria. These pathogens can be transported across oceans, posing risks to marine life, particularly bivalves like oysters and mussels, which can ingest microplastics. This situation threatens aquaculture and potentially human health, as pathogens may transfer to humans through seafood consumption.

What are microplastics primarily composed of?

• Metal particles

• Plastic particles

• Glass fragments

• Wood fibers

How are microplastics commonly formed?

• Through the melting of metals

• By the breakdown of larger plastic items

• From the erosion of rocks

• By the decomposition of organic matter

What is a significant concern regarding bacteria on microplastics?

• They can change the color of plastics

• They make plastics more durable

• They are resistant to antibiotics

• They can cause plastic to dissolve

Which marine organisms are particularly at risk from microplastics?

• Sharks

• Bivalves like oysters and mussels

• Dolphins

• Sea turtles

What potential impact do microplastics have on human health?

• They enhance immune response

• They may expose humans to pathogens through seafood

• They can cause skin irritation

• They improve digestion
