The impact of micropollutants on native algae and cyanobacteria communities in ecological filters during drinking water treatment

Strong cascading impacts of micropollutants on planktonic food web in urban river

“…22,23 To date, many efforts have been made to study the effects of micropollutants on planktonic communities in the field and laboratories. 18,21,23,24 Our previous study highlighted a strong effect of micropollutant compounds on bacterial communities 18 but not on micro-eukaryotic communities 24 in a subtropical river. Separately, algal communities have also been reported to be susceptible to micropollutant exposure in terms of primary productivity 23 and community composition.…”

“…15 Multiple studies have documented that each element in the planktonic food web is sensitive to environmental changes such as land-use changes and pollutant exposure [16][17][18] and disruption of one element would cause a chain of consequences in the food web and ecosystem functions. 16,19,20 Pollutants can affect microorganisms through direct exposure to microbial cells, 19 resulting in various effects at the individual level, such as behavioural impairment, physiological stress, and cell death 4,19 up to effects at the community level, such as the change in beta diversity 17,21 and ecosystem functions. 22,23 To date, many efforts have been made to study the effects of micropollutants on planktonic communities in the field and laboratories.…”

“…Separately, algal communities have also been reported to be susceptible to micropollutant exposure in terms of primary productivity 23 and community composition. 21 However, most of the previous studies investigating the micropollutant impact on organisms have mostly focused on a single group of organisms such as bacteria 17,18 or microeukaryotes. 24 Considering the complex nature of inter-trophic relationship in planktonic communities, the estimated pollutants effect based on a single group of planktonic food web may underestimate the extent of micropollutant impact to the entire food web.…”
