“…Furthermore, the need exists for personal exposure measurements, since microenvironmental or outdoor surrogates have been shown to have limited utility (Wallace 1996;Rodes et al 1991). Previous laboratory and eld studies have demonstrated that electrostatic precipitation may be an effective means for sampling such aerosols (Leith et al 1996;Volckens et al 1999Volckens et al , 2000. However, samples of semivolatile aerosols collected by electrostatic precipitators (ESPs) are susceptible to reactions and degradation due to ozone generated by the corona (Kaupp and Umlauf 1992).…”

“…Filter-based methodsused to measure aerosols with semivolatile constituents are subject to biases from adsorption and volatilization that may occur during sampling (McDow and Huntzicker 1990;Turpin and Huntzicker 1994;Volckens et al 1999;Tolocka et al 2001). The development and evaluation of suitable methods for quantitative measurement of semivolatile organic aerosols is of public health signi cance because this class of chemicals can include polycyclic aromatic hydrocarbons, pesticides, and many other known toxins (Harkov 1986;Finlayson-Pitts and Pitts 1999).…”

“…Die Aerosole waren alveolengängig. Die Konzentrationsmessung von Mineralölaerosolen in der Luft mit Filtern führt zu tendenziell niedrigeren Werten als die mit einem elektrostatischen Sampler gemessenen (Volckens et al 1999), sodass die Werte aus der Studie von Stula und Kwon (1978) möglicherweise zu niedrig angegeben sind.…”

The German Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area has evaluated 4 severely refined mineral oils [ 92062‐35‐6 , 72623‐83‐7 , 92045‐45‐9 , 92045‐44‐8 ] considering all toxicological endpoints. These mineral oils are severely refined to eliminate olefins and carcinogenic polycyclic aromatic hydrocarbons. The critical effect is lung toxicity which is observed as microgranulomas in two long‐term studies with rats and dogs at a respirable aerosol concentration of 100 mg/m 3 with a NOAEC of 5 mg/m 3 . A MAK value of 5 mg/m 3 has been set as the respirable fraction (R). Severely refined mineral oils have been assigned to Peak Limitation Category II, because the lung effects are due to a cumulative overload and an excursion factor of 4 has been set. Severely refined mineral oils are not genotoxic and not carcinogenic after oral, dermal or subcutaneous application to rats and mice. Developmental toxicity studies with a white mineral oil show a NOAEC of 1000 mg/m 3 and a NOAEL of 5000 mg/kg body weight in rats. After toxicokinetic scaling, the differences of the resulting respective concentrations at the workplace to the MAK value are sufficient. Therefore, damage to the embryo or foetus is unlikely when the MAK value is observed and severely refined mineral oils are assigned to Pregnancy Risk Group C. Skin absorption is very limited and does not contribute to systemic toxicity. Severely refined mineral oils are not regarded as skin or respiratory sensitizers.

“…More recently, other studies have focused on the re-entrainment in vapor form of cutting oils deposited on fibrous filters, when treating metalworking oil mist (Cooper et al 1998;Riss et al 1999) or during control sampling of ambient concentrations of aerosols (Volckens et al 1999;Simpson et al 2000;Volckens et al 2002;Park et al 2003;Simpson et al 2003;Verma et al 2006;Lim et al 2008).…”

Numerous sources of liquid aerosols are to be found in industrial environments. Such aerosols may, for instance, be cutting fluids, pesticides, etc., that are harmful or even toxic to humans. To control and reduce worker exposure to potentially toxic aerosols, these latter are usually filtered through fibrous filters. When nonsaturated air traverses a clogged filter, however, the drops deposited on the fibers may evaporate. Consequently, workers are exposed to greater amounts of more concentrated vapors than the initial state of the filtered aerosol. Furthermore, exposure readings are distorted by an artifact that may be significant. This study offers an experimental approach to long-term monitoring of the evaporation of a semi-volatile n-hexadecane liquid aerosol deposited on filters of varying efficiency. Results were modeled using two semiempirical models for identifying the basic parameters of liquid aerosol evaporation on fibers. For the first time ever it has been demonstrated that the Fick's first law, as previously suggested by models proposed in the literature, does not control evaporation kinetic.
