Abstract The paper gives results of testing five latex paints, containing organic mercury additives, in small environmental test chambers to determine the emission rates of mercury. Two of the paints contained phenyl mercuric acetate (PMA); the other three contained different additives. Gypsum wallboard was used as the test substrate. Testing was conducted in the dark and under fluorescent lights to determine if photodegradation of the mercury was occurring. Chamber vapor samples were collected on hopcalite sorbent and analyzed by cold-vapor atomic absorption spectroscopy (AAS) to determine total mercury. Sampling with graphitized carbon sorbeents showed that no organic mercury was emitted. A nth order source emission model was used to fit the chamber mercury concentration vs. time data. The results of the study showed high initial emission rates followed by slow emissions over an extended period of time. There was no apparent effect of light. The type of additive may affect the emission rates.
