It has been known that there are more than 50 species of mosquitoes in Korea but little study was done on distribution of summer mosquitoes species in Seoul. The author collected and investigated the species and seasonal distribution of mosquitoes in Seoul from 1967 to 1972 1) The most abundant species of summer mosquitoe was A. vexans nipponii, 30~70% of total mosquito population. 2) The next abundant species was C. pipiens but there was wide frequencies according to different years. 3) C. tritaeniorhynchus, the vector of Japanese encephalities, was third in order, possesed about 9% of total mosquitoe popuiation every year and reached peak in August and September. 4) It was found that there were 7 species of mosquitoes commonly in Seoul City.

This study examines the effect of the benzotriazole on the corrosion properties of 316L stainless steel in synthetic tap water. Electrochemical tests, surface analyses and quantum study were conducted for evaluating corrosion behavior and adsorption mechanism. In case of stainless steel in the synthetic tap water, the adsorption layer of benzotriazole is not uniform due to the low adsorption. The benzotriazole is preferred to ionic state in alkaline condition like synthetic tap water. Thus, the formation of metal-benzotriazole complex was difficult, and which confirmed in FT-IR analysis. The ionic state of benzotrizole in alkaline environment caused the electrostatic repulsion force and the strong tendency of donating electron obstructed the adsorption of ionic benzotirzole. In addition, the lack of d-orbital of Cr made hard to adsorption of the benzotrizle on the stainless steel. This non-uniform adsorption layer of benzotriazole on the stainless steel surface induced the localized defect sites which decrease the pitting resistance of stainless steel.
