Chlorophyll a levels reveal medium eutrophication in Puzhehei Lake.
The researchers studied chlorophyll levels in Puzhehei's water areas, analyzed their correlation with water quality, and evaluated eutrophication. They found that chlorophyll a concentration in Puzhehei is 4.00 mg/L, positively linked to TN and TP. The water in Puzhehei Lake is at a medium eutrophication level.
