Results and discussion

Any other information on results incl. tables

Volatilization of 2- hydroxyethyl methacrylate from moist soil surfaces  is not expected to be an important fate process given an estimated  Henry's Law constant of 4.6X10-9 atm-cu m/mole, using a fragment constant  estimation method.

Volatilization from water surfaces is not expected based upon an  estimated Henry's Law constant of 4.6X10-9 atm-cu m/mole(SRC), developed  using a fragment constant estimation method.

Applicant's summary and conclusion

Conclusions:
Volatilization of 2- hydroxyethyl methacrylate from moist soil surfaces and from water surfaces is not expected to be an important fate process given an estimated  Henry's Law constant of 4.6X10-9 atm-cu m/mole, developed using a fragment constant  estimation method.
