The aim of this study is to gain more knowledge on the impact of early life pesticide exposure on premature aging. The effect of a low dose of the insecticide permethrin administered to rats during early life (1/50 LD50, from 6th to 21st day of life) was analyzed by measuring some metabolites in plasma and urine of 500- day-old animals. Significant differences in early life treated rats compared to the control group were found in the plasma levels of Ca++, Na+, 25-hydroxy-vitamin D, adrenaline, noradrenaline, nitric oxide, cholesterol and urea while in urine only Na+ content was different. These results add information on the impact of permethrin during the neonatal period, supporting the evidence that early life environmental exposure to xenobiotics has long-term effects, inducing modifications in adulthood that can be revealed by the analysis of some macroelements, metabolites and catecholamines in plasma, when rats are 500 days old.

Abstract

The aim of this study is to gain more knowledge on the impact of early life pesticide exposure on premature aging. The effect of a low dose of the insecticide permethrin administered to rats during early life (1/50 LD50, from 6th to 21st day of life) was analyzed by measuring some metabolites in plasma and urine of 500- day-old animals. Significant differences in early life treated rats compared to the control group were found in the plasma levels of Ca++, Na+, 25-hydroxy-vitamin D, adrenaline, noradrenaline, nitric oxide, cholesterol and urea while in urine only Na+ content was different. These results add information on the impact of permethrin during the neonatal period, supporting the evidence that early life environmental exposure to xenobiotics has long-term effects, inducing modifications in adulthood that can be revealed by the analysis of some macroelements, metabolites and catecholamines in plasma, when rats are 500 days old.
