Sorption and microbial degradation of toluenediamines and methylenedianiline in soil under aerobic and anaerobic conditions
Article Abstract:
Results revealed that both isomers of toluenediamine (TDA) and 4,4' methylenedianilide (MDA) were sorbed more strongly under aerobic than anaerobic conditions. An immediate biodegradation, with the recovery of 2-3% 14 CO2 after only 3 days, is observed after mixing 14carbon-labeled TDA isomers and MDA with aerobic soil. Anaerobic methanogenci conditions allow no recoverable 14CH4 or 14CO2 even after 71 days of incubation.

Pesticide stratification in an engineered wetland delta
Article Abstract:
The amount of accumulated pesticides appears to be dependant on the timing and the season of pesticide application, according to research analyzing an engineered wetland. The traditional method of only analyzing finer grained sediments may be inappropriate because most of the pesticide accumulation may occur during a period of coarse grained sediment deposition.
