Floodplain pans are hydrologically dynamic in nature and characterised by variables such as chlorophyll-a (chl-a), water, and sediment chemistry over their hydroperiods. The present study investigated the spatio-temporal variations in water and sediment physico-chemical, and chlorophyll-a concentration characteristics of six floodplain pans found in the Ramsar declared Makuleke wetlands, Kruger National Park, South Africa. The water and sediment physico-chemical variable values were generally elevated during the high-water period, whereas chlorophyll-a concentrations varied across pans and hydroperiod.

- Human activities like agriculture and mining significantly contribute to water pollution, affecting microbial communities, though the specific impacts of combined pollution sources are not fully understood.
- A study conducted in South Africa’s Olifants River catchment used advanced genetic sequencing to analyze the effects of chronic pollution on bacterial and archaeal communities, revealing variations in microbial diversity between water and sediment samples.
- While pollution did not affect the overall diversity (alpha diversity), it altered the composition and predicted functions of microbial communities, with specific bacteria serving as indicators of pollution levels, providing potential tools for assessing water quality degradation.
