100 percent of people carry at least 1 type of pesticide
Date:1/4/2008

rs analyzed the samples and measured 6 different POC concentration levels: DDE, a principal metabolite in DDT (a pesticide used in Spain until the 80s); hexachlorobenzene, a compound used as fungicide and currently released by industrial processes; PCBs: compounds related to industrial processes; and Hexaclorociclohexano, used as an insecticide and currently used in scabies and pediculosis treatment.

The study carried out by the University of Granada concluded that 100% of subjects analyzed had DDE in their bodies, a substance banned in Spain, and other very frequent components such as PCB-153 (present in 92% of people), HCB (91%), PCB-180 (90%), PCB-138 (86%9) and HCH (84%).

Juan Pedro Arrebola Moreno explains that higher levels of toxic substances were detected in women compared to men and in older volunteers compared to younger people, possibly due to the great persistence of these substances in the environment, which results in their biomagnification in the food chain and in their bioaccumulation over time. The scientist added that there is another theory known as Efecto Cohorte (Cohort effect) that explains the high quantities of these substances in older people. According to this theory, those born in periods of higher contamination suffered the consequences more than those born with the current bans on such pesticides.

The impact of diet

This study indicates that diet is an important factor in POC concentration, as the ingestion of some aliments, particularly those of animal origin and high fat content, triggers a greater presence of these toxic substances in the human organism.

Juan Pedro Arrebola Moreno states, There are few studies in Spain measuring POC levels in wide samples of the population, which means that some compound levels in the general population are unknown. Consequently, this study will improve the knowledge of such levels, and will identify those gro
