Development of nationally representative exposure factor database for children's products in Korea.

ABSTRACT:

Background

Children may be exposed to harmful chemicals from their products. Accurate exposure factors are critical for exposure assessment of children's products. Product usage pattern parameters are relatively limited compared with the chemical concentration, children's physiological and behavioral parameters.

Objective

The aim of this study was to determine nationally representative Korean exposure factors for the usage patterns of children's products by sex, age, and season.

Methods

Using proportional quota sampling, a survey of 10,000 households with children aged 0-12 years was conducted twice, once in summer and winter. The children's ages were divided into four groups: infant (0-2 years old), toddler (3-6), lower-grade elementary student (7-9), and higher-grad
