Photochemical degradation in air :
Atmospheric photolysis half-life:
30d - 23d, based upon measured rate of photolysis in distilled 
water under sunlight.

Photooxidation half-life in air:
2.37yr - 86.5d, scientific judgement based upon estimated rate 
constant for reaction with hydroxyl radical in air.

360  12mo - 2d,
in ground water: scientific judgement based upon estimated unacclimated aqueous aerobic and anaerobic biodegradation half-lives.
  Howard 1991
 
Aerobic degradation in water :
Aerobic half-life:
6mo - 4w, scientific judgement based upon aerobic natural water 
die-away testa data (Howard 1991).

water die-away test data for 2,4-dinitrotoluene. 
Reduction of 
the nitro group observed in these studies may not be due to 
biodegradation (Howard 1991).
