摘要
The production of odorant 2-methylisoborneol (MIB) in water bodies by Planktothrix sp. has not been understood very well. Through a four-year investigation in Miyun Reservoir, a mesotrophic drinking water reservoir known to have MIB episodes, it was found that Planktothrix sp. blooms during September and October cause high levels of MIB in the reservoir. Measurements (n = 887) of MIB concentrations and biomass of MIB-producing cyanobacteria at different sites and depths revealed that shallow regions of the reservoir serve as the major habitat for Planktothrix sp. due to light penetration and nutrient-rich sediments. Quantile regression analysis indicated a 90% risk of MIB exceeding the odor threshold (15 ng L−1) when Planktothrix density exceeded 4.0 × 10⁵ cells L−1, reduced to 10% at densities below 1.6 × 10⁴ cells L−1. This study enhances understanding of Planktothrix sp. ecology and offers insights for managing taste and odor (T&O) issues in drinking water sources.
