Algal growth potential and oxidative stress in Ankistrodesmus falcatus exposed to waters from Xochimilco Lake system, México

A study on the water quality of Xochimilco Lake, part of Mexico's UNESCO World Heritage Site, reveals significant toxic effects on the native microalgae species Ankistrodesmus falcatus. The research found that water from urban, tourist, and agricultural zones induced oxidative stress in the algae, impairing its antioxidant enzyme activity and growth potential. This spatio-temporal impact of pollution was evident across multiple study periods, highlighting the severe deterioration of water quality in the lake system. The findings underscore the need for urgent intervention to mitigate environmental degradation and protect this critical ecosystem.
