懸念が表明されている。2. Description of the Related Art Recently, low-concentration various chemical substances widely diffused in the environment have become a serious problem. Such substances include, for example, DDT, dioxins, PCB
A wide variety of phenols, bisphenol A, phthalates, nonylphenol and the like are known. Among these substances, there are those that show remarkable toxicity such as teratogenicity, mutagenicity, etc. In addition, it is suspected that the action of disrupting endocrine in vivo in a small amount generally called an environmental hormone Things have been reported in large quantities. Therefore, various regulations are being considered for the release of some of these substances into the environment. For example, dioxins are released with the incineration of organic chlorinated resins, and various new incineration techniques have been used to reduce the amount of emission. It is also known that bisphenol A and phthalates, etc., which are partially contained in the resin and are released gradually with the aging of the resin, seem to be harmless, but have their endocrine disrupting effects. Some scholars have raised concerns.

集める技術が必要である。[0003] It is extremely difficult to dramatically reduce the concentration of chemicals released into the environment as described above in the near future. These chemicals already released are present in large quantities in the environment, and even if their emissions are gradually reduced in the future, it is difficult to reduce them dramatically. Furthermore,
It is generally difficult to confirm whether or not these chemicals are harmful, and the number of compounds that require such confirmation is enormous, and confirmation takes a long time. For the time being, there is a demand for the development of a technology that releases a certain amount of these trace chemicals into the environment and captures them so that they are not ingested by the human body. For example, it is desired to capture these harmful trace chemical substances contained in food and drinking water. In particular, it is desired to reduce the intake for pregnant women and infants. In addition, it is necessary to analyze these chemical substances efficiently in various countermeasures. Even in such a case, a technique for efficiently collecting these chemical substances is required.

It is obtained by molding the resin composition containing a polycarbonate resin as a resin material. As a molding method, a method generally used for molding a polycarbonate resin or the like can be used, and molded articles of various forms and applications can be obtained. Since the obtained molded article contains a polycarbonate resin as a resin material, bisphenol A as a residual monomer may normally be released from the molded article.
However, the chemical substance capturing agent of the present invention contained in the molded product captures this bisphenol A and suppresses its release. In particular, when this resin molded article is used for tableware for infants, the amount of bisphenol A intake of infants can be suppressed as compared with the conventional case. Examples of the tableware for infants include a baby bottle, a dish, and the like, and the use in a baby bottle is particularly useful.
