compounds having aromatic or hydrophobic (water-insoluble) chemical structures (i.e., organic pesticides or anthropogenic hydrocarbons), react strongly with humic acid. This property makes it an effective agent in sequestering many of the pollutants in terrestrial and aquatic environments. Fulvohape Väiksema molekulmassiga kui humiinhape. This organic matter is soluble in strong acid (pH = 1) and has the average chemical formula C135H182O95N5S2. One of two classes of natural acidic organic polymer that can be extracted from humus found in soil, sediment, or aquatic environments. Its name derives from Latin fulvus, indicating its yellow colour. Its structure is best characterized as a loose assembly of aromatic organic polymers with many carboxyl groups (COOH) that release hydrogen ions, resulting in species that have electric charges at various sites on the ion

Huumus muudab mulla viljakaks. Fulvohapped humiin humiinhapped *Fulvohapped (< lad. fulvus `punakaskollane'), huumushape, mis lahustub leelistes ja nõrkades mineraalhapetes. C135H182O95N5S2. *Humiinained- on komplekssed, amorfsed orgaanilised ühendid (polümeerid), mis on tekkinud enamikus taime-, vähemikus loomajäänuste humifitseerumisel mullas ja setetes. Humiinained, erinevalt humiinhapetest, leelistes ei lahustu; lisaks ei lahustu mineraalhapetes ega vees. Sõltuvalt metallist, millega humiinained on seotud, eristatakse humiine (seotud kaltsiumiga) ja ulmiine (raua ja alumiiniumiga). *humiin- huumuse peamine, lahustumatu komponent. Olles lahustumatu, ei ole
