Natural stressors in uncontaminated sediments of shallow freshwaters: The prevalence of sulfide, ammonia, and reduced iron
Potentially toxic levels of three naturally occurring chemical stressors (dissolved sulfide, ammonia, and iron) can occur in freshwater sediments, although their roles in shaping ecosystem structure (i.e., plant and animal communities) and function (e.g., biologically mediated elemental cycles) have received little study. This critical review discusses the prevalence and ecological effects of ...
