Review of aquatic biomonitoring section on indicators April 6 2021
Good job on the algae as indicators section. Most of my comments listed below are edits to make sentences clearer and make their meaning more accurate. One additional thing you might want to connect this section to is the use of algae in paleolimnology. This field looks at algae changes through time by taking cores from lakes that allow researchers to look at the algal species in lower, old sediments and the top, recent sediments. There is a good paper on paleolimnology and bioindicators titled: Paleolimnological Approaches to the Evaluation and Monitoring of Ecosystem Health: Providing a History for Environmental Damage and Recovery. See what you think, I don't think it's necessary but might be an interesting connection to make.

Here are the specific edits:

"The concentration of chlorophyll a expresses the algal density in a system which can estimate the toxicity level based on the amount of algae present." I agree that chlorophyll-a is used as a proxy for algal biomass, but the concentration of chl-a in an aquatic system depends on many things - the time of year, nutrients etc. and not just toxicity. Perhaps I'm missing something here, but I would fix this sentence so it's clear how chlorophyll-a indicates toxicity.

In the second sentence, you should indicate what they are being responsive to - perhaps responsiveness to environmental change?

Clarify "growth order of species". Perhaps you mean something like the algal community composition shifts predictably when exposed to specific pollutants?

Not sure what you mean here "which is positively correlated to temperature." Do you mean the herbicides have a greater effect at high temperatures? clarify the sentence

"The toxic effect on the photosynthesis of algae.." Include what is being toxic. For example, the toxic effect of herbicides on algae...

"with decreasing tolerance among algal species." Does this mean some species are sensitive to arsenic below 0.8 mg/L? clarify this sentence

The sentence that begins with "Heavy metals" - this sentence indicates that heavy metals have tolerance. Rephase to indicate that the algal communities can exhibit tolerance to heavy metals
