title: [Migration of eight harmful elements from household products made with synthetic resin that infants may swallow by mistake].
abstract: Harmful elements are used as stabilizers and colorants in synthetic resin products. Accidental ingestion of harmful elements from such synthetic resins by infants is a dangerous health hazard. The Japanese Food Sanitation Law and the International Standard ISO 8124-3 "Safety of toys-Part 3: Migration of certain elements" control the levels of migrated harmful elements, such as lead or cadmium, from infants toys. However, the levels of migrated harmful elements from household products that are not infants toys are not controlled, since they are not covered by the law or standard. Therefore, we investigated the level of eight harmful elements (antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium) migrated from household products made of synthetic resin that infants may swallow by mistake. The extraction test of ISO 8124-3: 2010 was executed in 135 products (total 150 specimens), and the concentration of these elements was measured by inductively coupled plasma mass spectroscopy (ICP-MS). As a result, 1810 mg/kg and 1660 mg/kg of lead, exceeding the maximum acceptable level of the ISO standard, migrated from two products. In addition, lead and/or chromium at levels more than 1/10 of the maximum acceptable levels of the ISO standard migrated from four products. Household products that infants may swallow by mistake should ideally not release harmful elements such as lead and chromium.
