| Outline of Final Research Achievements |
WHO recommended to use DDT for controlling Anopheles, and allow to use more than 5000 tons as indoor residual spraying (IRS) in developing countries mainly in Africa. On the other hand, DDT is well known chemical that is persistence in the environment and has long half-life, with carcinogenicity and endocrine disruption. IRS is considered low environmental burden because spraying occurs inside the house, however, there is insufficient research about the effect on human and animals. From our data, chicken accumulated very high concentration of DDT with the cancer risk for humans health. Moreover, wild rats was accumulated DDT with exceeded the levels that in experimentally exposed rat had cause the liver function disorder. Furthermore, I could detect DDTs from all the examined eggs from wild birds.
These results indicated that DDT IRS that has been considered as low environmental impact has potential toxicological effects and environmental risks.
