To study on the level of serum di-n-butyl phthalate (DBP), di-2-ethylhexyl phthalate (DEHP) in normal children by using gas chromatography.
Gas chromatography method was established. DBP, DEHP in normal children were detected, and their reference level was calculated, DBP and DEHP level in different age and genders were analysed.
DBP could be detected in 110 serum samples from total 310 samples, and DEHP could be detected in 118 serum samples from the total 310 samples. The detected contrations of DBP range from non detectable to 0.98 ng/ml, P75 was 0.68 ng/ml, P95 was 0.75 ng/ml. There was no difference in the detection ratios between females and males, while baby group detection ratios was lower than other groups. The detected contrations of DEHP range from non detectable to 0.94 ng/ml, P75 was 0.67 ng/ml, P95 was 0.74 ng/ml. There was no difference in the detection ratios between females and males. While there was difference among age groups.
The study domonstrated that DBP and DEHP concentrations in normal children are very low. The refrence level of DBP was suggested as lower than 0.75 ng/ml, DHEP was suggested as lower than 0.74 ng/ml.
