Abstract
Analysis of the hexane extract of an aqueous solution of sodium humate (Aldrich Chemical Co.) by high resolution gas chromatography (HRGC) has indicated the presence of l, 2‐dibromo‐3‐chloropropane (DBCP) in parts per billion (ppb) range. Residues of DBCP in the humate extract were confirmed by a purge and trap‐GC technique and HRGC‐mass spectrometry (HRGC‐MS). Mass spectra of the hexane extract of the humate solution matched with the EPA‐NIH mass spectral data for DBCP. The significance of association of DBCP with humate is discussed in relation to the fate of anthropogenic substances, including agricultural chemicals, in the environment.Keywords
