Exploration of 2-MIB Concentration Levels and Spatiotemporal Distribution Characteristics in Typical Reservoirs in Dongying City
This paper explores the concentration levels of 2-methylisoborneol(2-MIB)in 8 typical reservoirs in Dongying City,and analyzes the spatiotemporal distribution characteristics of 2-MIB.The research results show that among the 8 typical reservoirs,the concentration of 2-MIB is 27.3~182.0 ng/L,compared with other reservoirs in China,the typical reservoirs in Dongying City have a moderate level of 2-MIB;the temporal trend of 2-MIB concentration in most reservoirs in Dongying City is obvious,mainly due to the influence of temperature on algal activity,which in turn affects the concentration level of 2-MIB,however,policy tilt has resulted in a few reservoirs maintaining 2-MIB concentration within a certain range;in terms of spatial distribution,the closer the reservoir is to the city center of Dongying,the higher its 2-MIB concentration level,overall,the 2-MIB concentration in each reservoir shows a pattern where the central area is higher than the surrounding area.
