Conversion of metam sodium and emission of fumigant from soil columns

  title={Conversion of metam sodium and emission of fumigant from soil columns},
  author={Wei Zhenga and Scott R. Yatesb and Sharon K. Papiernikc and Joe Nunezd and George E. Brown},
Metam sodium is the most widely used soil fumigant in the United States. The primary breakdown product of metam sodium in soil is methyl isothiocyanate (MITC), an active pesticidal agent with a high toxicity and a great potential for volatilization. Reducing atmospheric emissions of MITC is therefore critical to maintain air quality. The objective of this study was to examine the rate and efficiency of conversion of metam sodium to MITC in soil and to investigate the potential of using surface… CONTINUE READING
