Pesticide Impact on Diatoms in Freshwater Environment

The researchers investigated how pesticides influenced photosynthesis and biomass development in diatoms and other algae.There has been minimal investigation into the effects of these toxic compounds on the internal components of diatom cells.It was discovered that diatoms exposed to harmful substances had nuclear alterations and cell wall abnormalities.However, the specific biological processes that cause these alterations and aberrations remain unknown.Pesticide susceptibility varies greatly across diatom species, as has been thoroughly reported.The capacity of eutrophic and small species to survive pesticide treatment has been extensively established.Smaller species may be less susceptible to oxidative stress owing to better cell defences.However, in general, explaining the reasoning for species-specific tolerance differences has proved difficult thus far.Within this perspective, a crucial topic for future research is understanding diatom intracellular toxicity and the link between these effects and the disturbance of community species composition.
