“…This indirect impact on other species results from direct impact on plants, which mostly occurs in surface waters after deliberate use in order to control unwanted plant species in surface waters (Solomon et al, 2014). Adverse effects of herbicides on nontarget aquatic primary producers, both algae and plants, have been studied thoroughly (Knauer et al, 2008;Pereira et al, 2009;Dalton et al, 2013;Della Vechia et al, 2016;Knežević et al, 2016;Nagai et al, 2016;Stevanović et al, 2013Stevanović et al, , 2019Chamsi et al, 2019;Nagai, 2019). Arguments in favour of significant differences in sensitivity between flotant and rooted species have led to an extension of risk assessment framework for herbicides.…”
