Although Mohr 5 quotes values <strong>of</strong> 30 μg/m 3 for terpene aggregate and 15 μg/m 3 for a<br />

single terpene compound from a scheme <strong>of</strong> Seifert, he considers values <strong>of</strong> 60 μg/m 3 for<br />

terpene aggregate to be more appropriate according to his experience. He also discusses aggregate<br />

values <strong>of</strong> 200 μg/m 3 (these exceed the olfactory threshold level) as posing possible<br />

health hazards in individual cases. These concentration limits only concern monoterpenes<br />

(pinenes, d-limonene, 3-carene) not other terpene products (e.g. sesquiterpenes). 5<br />
