“…The adsorption on clay or organic matter binding sites is apparently a temporary process. From studies with other pesticidal compounds it might be concluded that chemical reactions with soil organic matter components render them stable (Helling and Krivonak, 1978a; Hsu and Bartha, 1976;Mathur and Morley, 1978;Stevenson, 1976), resulting in a drastic decrease of bioavailability.…”

“…Mathur and Morley demonstrated the incorporation of methoxychlor [1,1,1-trichloro-2,2-bis(p-methoxyphenyl)ethane], a relatively nonmobile pesticide, into humic substances during its formation both by microbial (83) and purely chemical processes (84). From the humic material formed from culture containing methoxychlor and a fungus, no methoxychlor was detected in the benzene extract.…”

Chemical reactions of organic compounds including pesticides at the interlayer and exterior surfaces of clay minerals and with soil organic matter are reviewed. Representative reactions under moderate conditions possibly occurring in natural soils are described. Attempts have been made to clarify the importance of the chemical nature of molecules, their structures and their functional groups, and the BrĂ¶nsted or Lewis acidity of clay minerals.

“…The interactions between humic substances [humic acids, fulvic acids, humins, and dissolved organic matter (DOM)] and hydrophobic organic compounds have been studied by several groups. Cholesterol (1), polychlorinated biphenyls (PCB) (2)(3)(4)(5)(6)(7)(8)(9), phthalate esters (10)(11)(12)(13)(14), alkanes (11)(12)(13)15), fatty acids (11,13), polynuclear aromatic hydrocarbons (PAH) (5,12,(14)(15)(16)(17)(18)(19), mirex (20-22), chloranil (23,24), DDT (3,8,9,14,(25)(26)(27)(28), and other pesticides (9,14,(29)(30)(31) bind to humic substances. Binding interactions affect bioavailability (5,16,18,(32)(33)…”
