Ooo! That Smell!

Microplastics in the Olfactory Bulb of the Human Brain

This case series investigates microplastics in the olfactory bulbs of deceased individuals and examines their size, morphology, color, and polymeric composition.

It's taking everything within me not to post Lynyrd Skynyrd.

We're contaminating our brains with plastic. Fun!

Do micro-plastics enter our bodies form the foods we eat, or from the environment or other means? Explain to me like I'm five, please.

Science was never my strong suit.

Mostly from foods.

The average human body has all kinds of non-biologic material in it. The average person has quite a bit of mineral oil in their bodies, for instance, especially among women.

Thanks for the response.

That's what I was thinking as well, but I didn't know for sure.

Why is there mineral oil in the body and especially among women?

Just curious.

it's not something I've ever considered but greater use of apparently cosmetics by women might be one source.

Evidence for cosmetics as a source of mineral oil contamination in women - PubMed

The increase in MOSH concentration in human fat tissue with age suggests an accumulation over time. Cosmetics might be a relevant source of the contamination.

There is strong evidence that mineral oil hydrocarbons are the greatest contaminant of the human body, amounting to approximately 1 g per person.

Conclusions: The increase in MOSH concentration in human fat tissue with age suggests an accumulation over time. Cosmetics might be a relevant source of the contamination.

But compared to the number of bacteria in our body who cares? There are more bacteria in our bodies than cells.

Revised Estimates for the Number of Human and Bacteria Cells in the Body - PMC

Reported values in the literature on the number of cells in the body differ by orders of magnitude and are very seldom supported by any measurements or calculations. Here, we integrate the most up-to-date information on the number of human and ...

Thoroughly revised estimates show that the typical adult human body consists of about 30 trillion human cells and about 38 trillion bacteria.
