US scientists found 109 chemicals, 55 of which had never been seen in humans before, and 42 of which were of unknown origin, in their study on pregnant women and newborn survivors. His researchers called for governments to strictly control products used in industries, stating that the chemicals in question pass from plastics, pesticides, cosmetics, construction materials and medicines to the blood and some of them can be quite dangerous to the health of the mother and baby.
As part of the study published in Popular Mechanics, scientists took samples from 30 different pregnant women ‘umbilical cords and 60 different blood samples. In the analyzes, a total of 109 chemicals were detected, 55 of which had never been seen in humans and 42 of which had no known use in the body.
THE REQUIRED TECHNOLOGY HAS BEEN REACHED IN THE LAST 10 YEARS
However, the researchers announced that they believed that the 96 chemicals found had been in the human body for some time due to the increased use of plastics, but that they had just reached the technology required to view them.
High resolution spectrometry (HRMS) used to view chemicals was first developed about 50 years ago, but has only been made affordable to the scientific community in the last 10 years. This powerful tool can analyze dissolved matter in a sample by reflecting a beam of light. Then, scientists can determine the chemical signature of each chemical element and compound in the sample individually.
PLASTIC, AGRICULTURAL DRUG, COSMETIC, FLAME RETARDANT …
Analysis via HRMS revealed 662 chemical signatures when hit with positive ions and 788 when hit with negative ions. The researchers then combined similar samples, sequenced them, and identified 109 chemicals, most of which passed into maternal blood from different consumer products. Of these, about 40 were reported to be used in plastics, 28 in cosmetics, 25 in consumer products, 29 in pharmaceuticals, 23 as pesticides and three as flame retardants.
WHAT IS USED IN CONSUMER PRODUCTS SHOULD BE VERY CONSIDERED
