The direct approach to the estimation of WTP is to ask individuals how much they are willing to pay for a risk reduction. This method to assess WT P is usually referred to as the contingent valuation (CV) method. The first attempt to use the CV method to value risk reductions was by Acton (1973), who investigated the WTP for mobile coronary care units that would decrease the risk of dying after a heart attack. lones-Lee (1976) carried out an early study of the value of airline safety. Both these early studies were explorative in nature and used very small samples. Two later and much larger studies investigating the value of risk reductions are those of lones-Lee etal. (1985) and Smith and Desvousges (1987). 

Smith and Desvousges (1987) used the CV method to value risk changes from hazardous waste. A representative sample of 720 households in Boston, MA, was used in the study and 609 interviews were carried out with these households (i.e. a non-response of about 15%). The risk of dying from exposure was divided into two parts the risk of exposure and the risk of dying given that one is exposed. The sample was divided into eight different subsamples confronted with different risk reductions. The... 

To test the versatility of s-BLMs as a smart material, an amperometric sensor was constructed for ferri-/ferro-cyanide ions. The results have shown that (1) ferrocene can be very easily immobilized in the lipid bilayer on the tip of a metallic wire (s-BLM) system, and (2) ferrocene in a s-BLM on a Pt support increases the sensitivity by about two orders of magnitude to potassium ferri-/ferro-cyanide ion than that of a bare pt electrode. Recently, substituted ferrocenes were incorporated into s-BLMs on a Pt support and investigated using the CV. These demonstrate that the s-BLM system offers a novel approach to electrode modification by the simple incorporation of compounds within a lipid bilayer [11,12,16]. 

If one calibrates the SEC columns using the CV detector, it is possible to use this universal calibration relation and the CV detector to measure the number-average molecular weight of the polymer without reference to the DRI or other concentration detector. This method, which is due to Goldwasser (26), is based on the following identities ... 

Using the CV data in Figure 7.5, the individual specific capacitance of an electrode material can be estimated. For example, the electrode layer in Figure 7.5 is composed of two materials, the carbon support particles and... 

During the electrode fabrication process, it is not guaranteed that all of the ECS A will be available for electrochemical reaction, due to either insufficient contact with the solid electrolyte or electrical isolation of the catalyst particles. Therefore, Pt utilization is one of the most important parameters for evaluating a catalyst layer and an electrode. Using the CV technique, Pt utilization can be determined by measuring the electrochemical surface area of the Pt catalyst and the active Pt surface area (SA, m ) in a catalyst layer. Pt utilization can de defined as the ratio of the active Pt surface area in a catalyst layer to the electrochemical surface area of the Pt catalyst.
