| Outline of Final Research Achievements |
In this study, attention was paid to the KwaZulu-Natal state in South Africa, a vector control area in Africa, and its threat situation was investigated and toxicity impact assessment was conducted on living organisms.
As a result of investigation focusing on poultry, the DDT concentration in the liver showed a very high value of 920 ng / g ww in the median and 14,400 ng / g ww in the maximum value. As a result of gene expression analysis by real-time RT-PCR method, it became clear that it affected genetic group involved in lipid metabolism, synthesis and sex steroid hormone synthesis. The results of this study suggest that DDT gives certain effects to the living body, suggesting the need to implement more appropriate Vector control in the future.
