Ozone reactions with humic materials

PROBABLE FATE photolysis direct photolysis is not expected to be important, half-life for reaction with photochemically produced hydroxyl radicals in air 12 hrs oxidation atmospheric photooxidation after volatilization is the principal fate hydrolysis if compound is adsorbed by clays or fulvic acids, hydrolysis is not very important, important in acidic soils or soils processing acidic sites, if released to water, slow hydrolysis at neutral pH with a half-life of 50 yrs, at pH of 5, hydrolysis half-life 6.9 days volatilization high vapor pressure indicates strong volatilization, volatilization from the soil surfaces to the atmosphere and from water is an important fate process, volatilization half-life from a model river and pond 4.4hrs and 52 hrs respectively sorption expected to be adsorbed by clays and humic materials biological processes insufficient data reaction with ozone half-life 1.3 days rain wash-out should also be considered a likely fate process...
