A new approach is developed to determine people's exposure to organic and inorganic pollutants through hair analysis. This study involved 44 children. Two strands of hair were analyzed: to seek organic pollutant by liquid chromatography coupled with mass spectrometry and flight time (LC-MS-QTOF) and inorganic pollutant by inductively coupled plasma spectrometry with mass detector (ICP-MS). For organic pollutants, 100% of children show traces with an average of 38 toxicants per child with a predominance of synthetic intermediates (18%), insecticides (16%) and fungicides (13%). The 5 most commonly found products are metaldehyde (43 times), sorbic acid (43 times), hymecromone (42 times), hydroxychinolin (37 times) and pyrocatechol (34 times). For, 100% of children show inorganic pollutants (Metal Trace Element) at a rate at the limit of the toxic values we call “CONTROLLED LEVEL” with an average of 16 metal trace elements (MTE) per child. The MTE most often found are: aluminum, titanium, nickel, antimony, arsenic (43 times). For some elements, we define for the first-time the values in the hair.
