Art and craft material use patterns by pre-school and elementary school children at home and school: a year long survey for refining exposure assessments.

Background: Use frequency and times are critical parameters for estimating realistic chemical exposures associated with the use of consumer products. Very limited information is available in the published literature for children's use patterns of art and craft materials at home and school.

Objective: Conduct a year-long survey of art materials use at home and school by pre-school and elementary school children, teachers, and parents which can be used to refine chemical exposure assessments for these consumer products.
