Additional information

Cyanide discharged to into the air will remain in the air, and that which is discharged into the surface water will remain mainly in the water. The Henry's Law Constant coefficient (0.0054) is low, approximately 0.0054. With a low n-octanol-water partition coefficient of -0.25, HCN is not bioaccumulative. HCN is not strongly partitioned into the sediments or suspended adsorbents, primarily due to its solubility in water. Cyanides are relatively mobile in the soil, indicating that adsorption is unlikely to be significant in most aquatic environments.
