Scientific Concepts and Discoveries on Microplastics and Health

Over 430 million tons of plastic are produced globally each year.
In the Philippines, nearly 200 million shampoo sachets are produced annually.
Plastics take 20 to 500 years to decompose but gradually disintegrate into smaller particles over time.

Macroplastics: Large plastics visible to the naked eye (e.g., plastic bags).
Microplastics: Tiny plastics, almost invisible, that result from:
- Primary microplastics: Manufactured to be small (e.g., microbeads in facial washes and skincare products).
- Secondary microplastics: Result from the breakdown of macroplastics due to environmental factors like UV exposure.

Breakdown of larger plastics by sunlight (UV radiation) and environmental exposure.
Synthetic clothing fibers (polyester, nylon, polyamide, acrylic) shed microplastics during laundry, which enter waterways and eventually the ocean.
Over two million tons of microfibers enter the sea annually.
Microplastics are found in marine products and sea salt, particularly in coastal areas where salt is produced from seawater.

Microplastics affect marine life health and reproduction, including fish, oysters, and mussels.
Studies show microplastics contamination in salt samples worldwide; for example, 16 out of 17 samples in a 2017 study contained microplastics.

Microplastics enter the human body through:

Consumption of contaminated seafood and salt.
Inhalation of microplastics suspended in the air, especially in urban areas with high plastic waste.

Microplastics are small enough to penetrate respiratory and gastrointestinal tracts.

Plastics contain thousands of chemicals (about 13,000), with around 3,200 hazardous to human health.
Microplastics can carry bacteria, viruses, and toxic substances like heavy metals.
Chemical exposure from microplastics may cause:
- Physical damage to tissues.
- Toxic effects including neurological damage and endocrine disruption.
- Developmental effects and reduced fertility, particularly in females.
Studies have detected microplastic particles in human blood.

Ongoing studies continue to investigate microplastic impacts on human health.
There is a high likelihood of daily ingestion of microplastics, especially from food containers and take-out packaging.
The sea acts as a “sink” for plastic pollution, accumulating microplastics from land-based sources.

Reducing plastic use (“turning off the tap”) is essential to decrease microplastic generation.
Minimizing plastic consumption will reduce environmental contamination and health risks associated with microplastics.
