1. Formation and biorelease of bound residues of pesticides in two brazilian soils. II. Parathion.
The use of radiolabelled pesticides molecules'in research proved that some of the applied pesticides remain unexractable and become bound into the soil and other matrixes. Since the available methods to identify the nature of bound residues from parathion application were little effective, this study investigated the persistence and biorelease of C- parathio

2. Testing of some assumptions about biodegradability in soil as measured by carbon dioxide evolution.
Conversion to CO2 upon incubation in aerobic soil is one of the standard test procedures to assess biodegradability. It may be measured with unlabeled test compounds in biometer flasks. In this case, the background CO2 evolution by unamended soil is subtracted from the CO2 evolution by the amended soil and the resulting net CO2 evolution becomes the measure
