9.7  based upon estimated photooxidation half-life in air.
  Howard 1991
 
Half-life in soil, days :
7d - 1d,
scientific judgement based upon estimated unacclimated aqueous aerobic biodegradation half-life.
  Howard 1991
 
Half-life in water, days :
7d - 1d,
in surface water: scientific judgement based upon estimated unacclimated aqueous aerobic biodegradation half-life,
14  14d - 2d,
in ground water: scientific judgement based upon estimated unacclimated aqueous aerobic biodegradation half-life.
  Howard 1991
 
Aerobic degradation in water :
Aerobic half-life:
7d - 1d, scientific judgement based upon aqueous screening test 
data (Howard 1991).
 
Anaerobic degradation in water :
Anaerobic half-life:
