| Research Abstract |
Although it is important to understand the behavior of reactive oxygen species (ROS) for proper assessment of aquatic ecosystem due to the high reactivity of ROS with a range of molecules and chemical compounds, kinetics and mechanism of ROS redox reactions in particular the factor(s) influencing ROS formation still remain largely unclear. In this study, effect of photochemical reaction of humic substances on ROS generation was investigated, yielding that aromatic content in humic substance is one of major factors responsible for ROS generation (e.g., superoxide and hydrogen peroxide) in sunlit freshwater systems.
