Butadiene emissions rate increased only slightly and the rate of release 1, 2 Dichloroethane decreased slightly in accordance with the result of 1 measurement and Butadiene, 2 Dichloroethane in the atmosphere has not been changed.
Butadiene is a little higher emission rates and emission rates 1, 2 Dichloroethane decreased slightly in line with the results of Butadiene and 1,2 Dichloroethane. No change in the atmosphere
Butadiene have rate drop slightly higher, and with the release rate, 1 2 Dichloroethane slightly reduced, consistent with the measured results. And, Butadiene 1 2 Dichloroethane atmosphere and no change.
