Predicting the environmental fate and movement of plasticizers is currently hampered by a lack of information. There is also a lack of monitoring data to assess nonpoint sources. The aqueous solubility - a fundamental environmental property - of two of the 23 plasticizers has not been determined. As noted in this chapter, many properties such as Henry s Law constants, vapor pressure, organic carbon-water partition coefficients, octanol-water partition coefficients, bioconcentration factors, and photooxidation rates in the atmosphere were estimated using stractural analog models, empirical relationships based on other chemicals. Both biodegradation and adsorption appear to be the major mechanisms that control the fate of plasticizers released into the environment. Despite the

A large part of the discussion in this chapter has focused on polymer flooding recovery mechanisms and their sensitivities in layered heterogeneous 

Contact angle measurements, as discussed earlier, are limited in their applicability to ideal surfaces or to surfaces wetted by liquids of homogeneous composition resting in equilibrium. The nature of real surfaces, real adhesives and the pressure of bonding cannot be allowed for as encountered in real bonding operations. Nevertheless, some comparative information on surface energies and the wetting of some real surfaces may be anticipated. 

Optimisation of surface pretreatment is the key to maximising joint durability. The adhesive influences the surface oxide layer and the surface oxide layer influences the boundary layer polymer matrix the whole must therefore be viewed as a unique system for every adherend-adhesive combination. The interplay of chemical bonding 

In the practice of adhesive bonding for applications in construction, surface pretreatment is likely to be the most difficult process to control. The choice of treatments must be tempered by the scale of operations, the nature of the adherends, the required durability, the adhesive to be used, and the cost. The performance of joints constructed with cold-cure epoxies is likely to be critically dependent upon surface preparation, as exemplified by the experience of the Scottish Irvine Development Corporation. In 1978 they elected to use vertical externally-bonded steel plate reinforcement to strengthen the abutment walls of three pedestrian underpasses. A year later, the plates were reported to be falling off, accompanied by extensive interfacial corrosion the steel surfaces had been abraded by hand, and the concrete surfaces chemically etched. 

Generally, the adherend surfaces should be clean, dry, and free 

Experimental assessments of the effects of surface pretreatment are of limited value using mechanical tests unless environmental exposure is included. It is very sound policy to collect and examine information on joints loaded and exposed to natural weathering conditions rather than depend solely on laboratory experiments. It is clear that water is the substance which causes most problems in attaining environmental stability of bonded joints interfacial failure generally indicates that a better surface pretreatment would impart improved joint performance. 

Bile acids have previously been considered to have primarily promoting effects during tumourigenesis. However, there is increasing evidence that certain bile acids, particularly deoxycholic acid, have significant genotoxic effects that could contribute to tumour initiation. Deoxycholic acid demonstrates genotoxic effects at both acidic pH and neutral conditions. In the context of reflux 

Limiting the genotoxicity of bile acids might be alforded by interventions including anti-oxidant supplementation in susceptible patient groups.
