We studied the final test analytical method using the GC/MS method for 9 kinds of aromatic primary amines regulated in the EN71 standard of dye components for toys in Europe. Twelve commercially available textile products (toys and infant-toddler clothing) (20 parts of the products) were analyzed by the method. As a result, the amines could not be detected in all the products. This method had sufficient sensitivity as a qualitative analysis method for confirmation. However, it had problems with reproducibility, etc. as a quantitative analysis method, and it was considered that the method needed to be improved for higher accuracy.

The Food Sanitation Law of Japan provides that the amount of lead eluted from the paint film on baby toys must be less than 90 μg/g. However, the amount of lead eluted from paint films on products to which the Food Sanitation Law is inapplicable is not controlled even if the product is used by babies. We therefore investigated the amount of lead eluted from the paint films on household products which babies may use with reference to the Food Sanitation Law. In addition, we confirmed the validity of capillary electrophoresis for measurement of the lead concentration of test solutions. Of 105 products (107 paint films) such as stationery and hairpins, only one hairpin had a paint film that eluted a small amount of lead. The hairpin package carried a warning of the lead content. Nevertheless, household product which babies may use should ideally not contain lead.

本研究は，幼児期の傾いた図形に対しての認識の難しさに着目し，その図形認識の育成に効果的な絵本を作成することを目的とする．そのために，まず図形認識の育成に有効な知育玩具の検討を行った．さらに，先行研究におけるの図形指導プログラムや小学校算数科との関連を照査することで，幼小接続期を対象として行うことの必要性を示した．これらを踏まえて，今後作成する，傾いた図形認識を育むためのパズル絵本の構想を創出する．
