The fire-resistant chemical substance is related to the thyroid disease of the cat, has an influence on also the person?


　Is seen mainly in the American house cat the thyroid function of the cause obscurity which 亢 the Shin symptom, the carpet, the furniture and the mattress, the electric product, furthermore is included in also the pet hood the fire-resistant chemical substance which (fire-retardant chemicals) is the poly- bromination diphenyl ether which (PBDE) due to the possibility was reported. This substance as for the basis of harmfulness is not shown in the person, but you say that it cannot deny either the possibility.

　The american protection of the environment agency which executes research (EPA) Linda S. according to Birnbaum, the being disclosed level to PBDE the cat is much higher than the person. Thyroid function 亢, weight decrease and appetite 亢 Shin, there is a dehairing and a excitability etc with the condition which the cat of the Shin symptom shows. In the most lethal disease, the cat which is raised in the especially interior risk is high in the cat of old-age. Because the body [zu] [ku] [ro] is carefully in the cat and there is a habit which is done, it is thought that it is easy to take in the house dust which includes PBDE to internal.

　To the healthy influence of PBDE problem apparent as for reaching the point where it is done nineties latter half. The liver virulence and nervous virulence of PBDE are shown in animal research, it is found that it is relationship with the house dust and breast milk PBDE density. Although many of PBDE it has decreased with the independent movement of the manufacturer and the regulation of government, because it is the substance which is difficult to be disassembled it disappears from environment until, you say that long time is required. The furniture manufacturer presently has used the alternative substance.

　In latest research which is published to American environmental scientific magazine “Environmental Science & Technology” online edition on August 15th, 23 cats (inside 11 thyroid function 亢 the Shin symptom) picking the blood inspection body. As for the cat which has the disease, PBDE value was 3 times in comparison with the young cat and the cat which does not have the disease. PBDE is recognized by also the can entering cat hood, is many in those of the especially fish flavor. The result of analysis, the feed as for the can entering hood central cat, was 12 times that when PBDE value is the dry hood. As for PBDE disclosure of the cat, you say that it can reach also 100 times that of the American adult.

　Thyroid function of the cat 亢 reaching the point where you can see the Shin symptom started being utilized before approximately 30 years, same time PBDE in the interior supplies. As for the United States being the world, the utilization of PBDE is most, PBDE value of the person and is highest in the world, it is thought that the same diseased risk of the cat are high. Presently the same disease is recognized even at Canada, Australia, Japan and European every place. Also the affection of the person increases, for example bush former American president and bar rose lady, furthermore also the dog which the husband and wife raises has contracted a disease.
