Application of organic amendments to reduce volatile pesticide emissions from soil
Article Abstract:
There is a need to reduce atmospheric emission of volatile pesticides, including soil fumigants. One viable strategy is the application of organic wastes. This method is found to be an effective means of reducing methyl bromide (MeBr) and methyl isothiocyanate (MITC) volatility in fumigated soils. Reductions in MITC and MeBr volatility have been found to be directly linked to the humus' ability to enhance degradation of these compounds. Results show that 5% composted manure in 5 cm of surface soil reduced MeBr emission by 12% and almost completely eliminated MITC volatilization.

Sorption of polycyclic aromatic compounds to humic acid as studied by high-performance liquid chromatography
Article Abstract:
The retention characteristics of 45 polycyclic aromatic compounds (PAC) to humic acid were studied and found to be dependent on hydrophobic interactions as well as hydrogen and ionic bonding. Polycyclic aromatic compounds studied included polycycling aromatic hydrocarbons, N-,S-,O-polycyclic aromatic compounds and substituted PACs such as 9-substituted anthracenes, bromopyrenes and quinoline derivatives. Retention characteristics were studied through high-performance liquid chromatography.
