A study conducted by the Health Sciences team of the University of New Mexico (USA) has observed the presence of large number of plastic particles in the human brain, more than in other organs such as the liver or kidneys.
The research has been developed by taking post mortem samples, observing greater concentration in those collected last year than in 2016. Although the implications that these compounds have in human health are still not known, yes They demonstrate the consequences of a greater concentration of plastics in the environment, They point out scientists responsible for research.
The director of the research, Matthew Camlan, and his team used innovative techniques to analyze the distribution of micro and nanoparticles in samples of liver, renal and brain tissues – a total of 52 in the latter case – of people who were performed autopsies in 2016 and 2024. “The findings should activate the alarm,” collects an official statement.
Without evidence of its health effects
In the case of brain samples, all of the frontal cortex contained substantially higher concentrations of plastic particles than in the case of liver and kidney tissues. Comparing these findings with those of previous periods (1997-2013), there was a greater amount in the most recent samples.
Although a greater amount of particles in diagnosed brains with dementia was also observed, the authors They do not establish a causal relationship between these plastics and the effects on health, for which more studies would be needed. Although, they suggest that some variations could be due to geographical differences, since the specimens were taken in New Mexico and in localities of the US coast.
The Research on the presence of small plastics in living organisms are usually recurring Since recent years, as is the case of one of the last ones that located high concentrations in babies placenta.
