Humic substances (HSs) are a diverse class of natural compounds with no fixed chemical composition, formed from plant and microbial residues through the action environmental factors living organisms over many years. Despite extensive research spanning two centuries, complex variable nature HSs' structure remains subject scientific inquiry. These substances, notably humic acids, fulvic humin, play crucial roles in ecological processes due to their abundant functional groups resilience biodegradation. This review explores intricate properties HSs, classification, occurrence nature. It highlights different models proposed describe structural fragments emphasizing aromatic cores groups. The variability molecular weight distribution attributed polydisperse nature, is also discussed, along methods used for determination, such as exclusion chromatography. Furthermore, elemental compositions acids examined, detailing acid-base capacity heavy metal complexation. synthesis HSs sources, soil, peat, coal, artificial processes, covered, showcasing like alkaline extraction hydrothermal treatment. Recent advancements humification, including oxidative ammonolysis Fenton reagent-based oxidation, reviewed potential producing environmentally friendly materials lignin waste biomass. study concludes by underscoring significance practical applications particularly agriculture, soil conditioning, remediation. make them promising candidates sustainable material production management. versatile beneficial human health potent antioxidant properties, immune-modulating effects, support gastrointestinal detoxification. Structurally diverse, they feature carboxyl, phenolic hydroxyl, quinones, ketonic carbonyls, amino, sulfhydryl, contributing stability amphiphilic In pharmaceutical applications, show promise drug delivery, therapies, wound healing, antimicrobial actions, biofilm disruption, underlining biocompatibility safety.
