Mineral Oil Hydraulic Fluids. No information identifying the major components of mineral oil or water-in-oil hydraulic fluids was located in the available literature, nor was any information located that described how the emulsifiers and other components in water-in-oil emulsion hydraulic fluids alter the environmental properties of the mineral oils contained in them. The carbon number range present in mineral oil hydraulic fluids probably is from C15 to C50 (IARC 1984 Shubkin 1993 Wills 1980). If automatic transmission fluids are typical of the mineral oil content in a hydraulic fluid, then mineral oil hydraulic fluids contain -90% mineral oil (Abdul et al. 1990 Papay 1989,1991). Therefore, the transport and partitioning of these hydrocarbons will largely account for the environmental behavior of mineral oil hydraulic fluids. Typical transport and partitioning information for hydrocarbons in this range is presented below this information is indicative of the transport and partitioning of mineral oils present in hydraulic fluids.

The formation of novel membrane-like materials based on LDHs has also been established. These materials are of relevance to separation and membrane technologies. A LiAl-LDH containing myrisate or hexanoate anions, for example, has the ability to partition pyrene from a methanol/water solution containing the polycyclic aromatic [132], No sorption of pyrene was observed for a LiAl(succinate) LDH, however, and this was attributed to a sieving effect of this compound towards the pyrene molecule. The sorption of polyaromatic hydrocarbons, such as pyrene, is important from an environmental perspective.

As PFSAs and PFCAs are both hydrophobic and oleophobic, and form multiple layers when mixed with water and hydrocarbons [49], i ow values are not appropriate or relevant for these PFCs [26]. Similarly, other partition coefficients and traditional environmental fate models based on air, water and octanol partitioning are not suitable for PFSAs and PFCAs.
