Experimental data for the decay of acrolein approximated first order kinetics. The reaction continued to completion in local waters but in buffered solution (pH 5.1-8.6) an equilibrium was reached after reaction of about 92% of the acrolein. It is proposed that data presented on the effects of pH on decay of acrolein may be used as a conservative estimate of dissipation rates in water where non-target organisms are at risk. In flowing water in two channels the 8 to 10 fold discrepancy between observed and predicted rates of dissipation was attributed to major losses in volatilization and adsorption. A relatively non-volatile reaction product (which gave a positive reaction with dinitrophenylhydrazine) accumulated initially but dissipated rapidly, probably by microbiological processes, when acrolein concentrations fell below about 2 to 3 ppm.
丙烯醛衰变的实验数据近似符合一级动力学。该反应在局部水域中持续进行直至完全，但在缓冲溶液（pH 5.1 - 8.6）中，约92%的丙烯醛反应后达到平衡。有人提出，关于pH对丙烯醛衰变影响的数据可作为对非目标生物面临风险的水体中消散速率的保守估计。在两条渠道的流动水中，观察到的和预测的消散速率之间8至10倍的差异归因于挥发和吸附造成的重大损失。一种相对不易挥发的反应产物（与二硝基苯肼反应呈阳性）最初会积累，但当丙烯醛浓度降至约2至3 ppm以下时，可能通过微生物过程迅速消散。
