Plastics Psychology?

Manufactured plastics are now ubiquitous. Microparticles of these substances, are found throughout environments. Vienna University studies suggest that microplastics appear in mouse brains, within 2 hours of their drinking contaminated water. One must caution, however, that the neurally-located particles may not actually be those from the drinking water. The mice could have incorporated microplastics earlier from their food, water or surrounding environment (https://www.theguardian.com/commentisfree/2023/may/01/plastic-is-already-in-blood-breast-milk-and-placentas-now-it-may-be-in-our-brains). Irrespective of the speed with which microplastics get from drinking water into mouse brains, these particles will also find their way into the human central nervous system. Microplastics have already been found in human blood, breast milk and placental samples. Humans are much longer-lived than mice. They will, consequently, be exposed to microplastic particles for decades. People will incorporate microplastics whilst in the womb, while being suckled and as breathing, eating and drinking adults. Microplastics in human brains, may well increase the risk of inflammation. Neurally-located particles may also cause neurological disorders. They may even prove linkable to neurodegenerative diseases, such as Alzheimer's or Parkinson's. We humans are very efficient at 'soiling our own nests'. We are less good about looking after our own health.
