Microplastics and Their Impact

What are microplastics and where have they been found?

• Large pieces of plastic found in oceans

• Tiny plastic particles found in the atmosphere

• Glass particles found in water

• Metal particles found in soil

What is the primary difference between primary and secondary microplastics?

• Primary microplastics are larger than secondary ones

• Secondary microplastics are directly released into the environment

• Secondary microplastics are used in manufacturing

• Primary microplastics are already small, while secondary ones form from larger plastics

What method did scientists use to study microplastic deposition?

• Soil analysis

• Atmospheric transport modeling

• Satellite imaging

• Oceanic sampling

What is the main source of microplastics found in the atmosphere according to the study?

• Oceans

• Agricultural dust

• Factories

• Roads

How do roads contribute to microplastic pollution?

• By providing energy to make plastics airborne

• By absorbing microplastics

• By reducing plastic waste

• By filtering microplastics

What potential health issue is associated with inhaling microplastics?

• Improved lung function

• Enhanced immune response

• Increased energy levels

• Respiratory conditions

What did the 2019 study using dummies reveal about indoor air?

• It has no impact on health

• It contains microplastics in every sample

• It is free of microplastics

• It is cleaner than outdoor air

What was observed in human lung cells exposed to polystyrene microplastics?

• Cells became more active

• Metabolic processes slowed down

• Cells died immediately

• Cells multiplied rapidly

What is a critical step in mitigating plastic pollution?

• Reducing research efforts

• Ignoring the problem

• Understanding how plastics enter the atmosphere

• Increasing plastic production

What is the expected trend if plastic production continues to grow?

• Plastic pollution will decrease

• Plastic pollution will have no impact

• Plastic pollution will remain the same

• Plastic pollution will increase
