What are Aquatic Humic Substances?

Aquatic humic substances are complex mixtures of organic compounds found in freshwater, brackish, and marine environments. They are formed through the decay of organic matter, such as dead plants and animals, and are known for their dark color and ability to absorb and bind to a variety of molecules.

These substances are composed of humic acids, fulvic acids, and humin. Humic acids are larger molecules that are less soluble in water, while fulvic acids are smaller and more soluble. Humin, on the other hand, is insoluble in water and consists of highly decomposed organic material.

The Role of Aquatic Humic Substances in Ecology

Aquatic humic substances play a crucial role in ecological processes. They act as a source of energy and nutrients for a wide range of organisms, including bacteria, fungi, and invertebrates. These substances provide a habitat and food source for many aquatic organisms, contributing to the overall biodiversity of ecosystems.

Furthermore, aquatic humic substances can influence the physical and chemical properties of water. They can affect the water's pH, nutrient availability, and light penetration. By altering these factors, humic substances can impact the growth and survival of aquatic plants and algae, which are the primary producers in many aquatic ecosystems.

Additionally, these substances can influence the transport and fate of pollutants in water. They have the ability to bind to heavy metals and organic pollutants, reducing their toxicity and preventing them from being readily available to organisms. This interaction between humic substances and pollutants has important implications for water quality and the health of aquatic ecosystems.

Biogeochemical Cycling of Aquatic Humic Substances

The biogeochemical cycling of aquatic humic substances refers to the processes by which these substances are produced, transformed, and decomposed within ecosystems. This cycling plays a crucial role in nutrient and carbon dynamics in aquatic environments.

During the production phase, aquatic humic substances are formed through the microbial breakdown of organic matter. This process involves the action of bacteria and fungi, which decompose the organic material and release the humic substances as byproducts. Once produced, these substances can be transported and distributed throughout the aquatic ecosystem.

Transformation processes, such as photodegradation and microbial degradation, can modify the properties of aquatic humic substances. Sunlight can break down the molecules, changing their structure and reactivity. Microorganisms can also interact with these substances, altering their composition and contributing to the cycling of nutrients and carbon.

Finally, the decomposition of aquatic humic substances is a key step in the release of nutrients back into the ecosystem. Bacteria and fungi break down the humic substances, releasing carbon, nitrogen, and other elements that can be used by plants and other organisms. This decomposition process ultimately completes the biogeochemical cycling of aquatic humic substances.

Humic substances occur in all kinds of aquatic systems, but are particularly important in northern, coniferous areas. They strongly modify the aquatic ecosystems and also constitute a major problem in the drinking water supply.
This volume covers all aspects of aquatic humic substances, from their origin and chemical properties, their effects on light and nutrient regimes and biogeochemical cycling, to their role regarding organisms, productivity and food web organization from bacteria to fish. Special emphasis is paid to carbon cycling and food web organization in humic lakes, but aspects of marine carbon cycling related to humus are treated as well.
