How does plastic enter the human body?
Plastic particles are ubiquitous pollutants in the living environment and food chain. They are found in the air, water, wildlife, and the food chain. A recent study has found microplastics in human blood for the first time, with four common plastics found in the blood samples of 17 out of 22 healthy adults. The study used a sensitive sampling and analytical method with double-shot pyrolysis and gas chromatography/mass spectrometry to measure plastic particles in human whole blood.
There are several ways through which plastic enters the human body, including:
- Inhalation: Microplastics can become airborne and be inhaled, entering the respiratory system. They have been found in human lung tissue, suggesting that inhalation is one route of entry.
- Ingestion: Microplastics can contaminate food and water sources, leading to their ingestion. They can settle on food crops, be present in drinking water, and accumulate in marine organisms, which can then be consumed by humans.
- Skin absorption: Microplastics are intentionally added to cosmetics and personal care products to improve their feel and finish. When these products are applied to the skin, there is a potential for microplastics to be absorbed.
- Placental transfer: Research suggests that microplastics can cross the placenta and reach the fetus. Additionally, babies can be exposed to microplastics through breast milk and the use of plastic feeding bottles and teething toys.
The presence of plastic in the human body, specifically in the blood, raises concerns about potential health risks. While the exact mechanisms of absorption, distribution, metabolism, and excretion of microplastics in the human body are not yet fully understood, there are worries about possible inflammatory responses, interference with hormones, and potential impacts on various organ systems.

What can be done to reduce plastic consumption?
Scientists have recently found microplastics in human blood for the first time, with four common plastics being identified in the blood samples of 17 out of 22 healthy adults. The health risks of this discovery are still unclear and require further research. However, the presence of plastic in our blood underscores the urgency of reducing plastic consumption to minimize potential harm to human health and the environment. Here are some ways to reduce plastic consumption:
Opt for Reusable Items
Carry reusable items such as water bottles, coffee cups, flasks, and shopping bags. Reusable items reduce the need for single-use plastic alternatives and can even save you money in the long run. You can also carry your own reusable cutlery, straws, and food containers when eating out to cut down on disposable packaging.
Recycle and Properly Dispose of Plastic Waste
Properly recycle and dispose of plastic waste to prevent it from ending up in landfills, oceans, and other natural environments. Before throwing away plastic items, check where each item should go to ensure it ends up in the correct recycling container.
Choose Plastic-Free Alternatives
Select plastic-free alternatives whenever possible. For example, you can switch to using wooden pegs instead of plastic ones or choose cosmetics and personal care products that are not packaged in plastic. Look for products packaged in glass or metal, which are more widely recycled and contain a higher proportion of recycled content.
Buy in Bulk and Refill
Purchase dried pantry staples, such as rice and beans, in bulk instead of buying them packaged in plastic bags. You can also take your own containers to refill with products like wet and dry goods at local refill shops.
Reduce Unnecessary Plastic Use
Be mindful of unnecessary plastic use. For example, avoid using plastic straws, even paper ones, as they contribute to resource consumption during production and disposal. If possible, eat at a restaurant or café instead of getting takeout to reduce disposable packaging and ensure the use of reusable crockery.
By implementing these changes and encouraging others to do the same, we can significantly reduce our plastic consumption and minimize the harmful effects of plastic on our health and the environment.
