Environmental Fate

Low micron-sized particles may stay suspended in undisturbed air for many hours and resuspension of settled low micron-sized particles from disturbed surfaces can occur(1). Ricin has a UV max of 280 nm(2) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). Ricin is very stable and to a great extent not affected by extremes in heat or cold environmental temperatures(3). Ricin is soluble in water and stable over a wide range in pH.
