Determination of Carbametamide Residues and Its Aniline Metabolite

Abstract

EDITOR B2, Gi, G2, and BiA under the conditions of the experiment. Differences in the behavior of strains of C. pyrenoidosa and C. vulgaris to the action of various herbicides can be and have been attributed to strain differences (Vance and Smith, 1969; Thomas et al., 1971) and to differences in growth conditions. By changing from autotrophic conditions to heterotrophic conditions by the addition of a reduced carbon source such as glucose, it has been shown that the inhibitory effects of some herbicides which affect the photosynthetic process on strains of C. pyrenoidosa and C. vulgaris can be reversed (Geoghagen, 1957; Ashton et al., 1966; Sikka and Pramer, 1968). In order to reduce the time of the assay and in order to avoid special provisions for a carbon dioxide source, glucose has been used as a carbon source under our conditions.The results presented here emphasize the importance of strain differences when Chlorella is used as a test organism.
