Yes there is. Both by affecting the ability to absorb other elements, and by the toxicity of iron itself.

Iron (Fe) is important for life, involving the transfer of oxygen, respiratory chain reactions, DNA synthesis, and immune function. The essentiality of this factor for all vertebrate life means that the uptake pathways and internal handling strategies are preserved between mammals and fish, and zebrafish have been widely used to understand the metabolism of vertebrates feat a mechanistic stage. At normal levels, iron is not lethal to any aquatic species, but at higher levels where iron does not dissolve in water, fish and other creatures cannot process all the iron they take from water or food. Iron will build up in the internal organs of animals, ultimately killing them. Higher levels of iron in fish and aquatic plants also have harmful effects on humans or animals that consume them.

High Fe concentration affects aquatic plants. The toxicity of Fe to plants could change its trait, anatomy, and species composition.

Large amounts of iron promote growth of algae, which can block sunlight from other plants and can disrupt habitats and feeding practices. Extensive algae presence lowers water freshness and promotes stagnation. ... High concentrations of iron sometimes result in increased acidity of water—killing or hurting aquatic life. https://www.cuteness.com/article/effects-iron-water-aquatic-life

Overwatering with iron-rich water can gradually cause a build-up of iron that may begin to damage the plant itself. ... Over time this can cause toxicity that can wilt, brown or even kill the plant. https://homeguides.sfgate.com/water-iron-okay-use-plants-68612.html

Excess iron can produce symptoms of stunted growth and discolored bronzing foliage. Some plants that are prone to iron toxicity include seed and zonal geraniums, lisianthus, African marigolds, pentas, New Guinea impatiens and lilies. https://www.growertalks.com/Article/?articleid=22052

Iron above 100mg/L causes plants necrosis or death. Iron toxicity leads to cause leaf bronzing and reduced roots oxidation power. The synthesis of chlorophyll, proteins as well as carbohydrates and the uptake of phosphate and nitrogen are inhibited seriously by excess iron and copper.

In some regions the concentration of iron in aquifers is very high, due to the geological conditions of the underground. Iron becomes oxidized when groundwater with low oxygen content rises to the earth's surface.

Oxidation of iron leads to formation of a precipitate of iron ocre (iron hydroxides) in surface water. The iron ocre covers surfaces like leafs of macrophytes or surfaces of other aquatic organisms (e.g. gills of ephemeroptera larvae) with harmful conequences. Coverage of leafes with iron ocre reduces light absorption of the plants and therefore decreases photosynthetic activity.

yes, a high amount of iron (fe) is produced toxicity in Aquatic plants and affect the growth of plants

yes , a high amount of iron is affected chemical composition of aquatic water

Plants are affected by the ambient concentrations of contaminants and aquatic plants are no exceptions, but the the response to the elevated concentrations depends on the plant species under consideration.

Yes, excess Fe concentration in aquatic environment has negative consequences on both plants and animal species. You can see the following articles:
