85. Several factors that complicate the assessment and control of exposure to individual agents will also affect cases of mixed exposures and will require similar special consideration. Such factors include:

 

(a) exposure to an agent for which there is no established limit or for which an OEL-ML has been set;

 

(b) the relevance of factors such as alcohol, medication, smoking and additional stresses;

 

(c) exposure of the skin to one or more agents that can be absorbed by this route, as well as by inhalation; and

 

(d) agents in mixture may mutually affect the extent of their absorption, as well as their health effects, at a given level of exposure.
