Freezing point of dcm
WebThe arithmetic means of DCM measured in hazardous waste sites in New Jersey ranged from 0.35 µg/m3 to 5.6 µg/m3. At one site, a mean concentration of 40 µg/m3 and peak levels of 190 µg/m3 were found (8). DCM was found in more than 75% of samples taken in the ambient air at a New Jersey sewage treatment plant, with a peak concentration of ...
