Cables health effects

The effects of endosulfan have not been studied in children, but they would likely experience the same health effects seen in adults exposed to endosulfan. Data in adults, mostly derived from cases of accidental or intentional acute exposure (ingestion) to large amounts of endosulfan, indicate that the primary target of endosulfan toxicity is the nervous system. The effects are manifested as hyperactivity and convulsions and in some cases have resulted in death (Aleksandrowicz 1979 Blanco-Coronado et al. 1992 Boereboom et al. 1998 Cable and Doherty 1999 Lo et al. 1995 Terziev et al. 1974). These effects have been reproduced in experimental animals. 

Chlorinated paraffins (mainly CPVC) are widely used in PVC to have greater resistance to ignition and combustion than general purpose plasticisers. However, the effects of chloroparaffins on health is still a controversial issue and their use as flame retarders in PVC applications for cables, wall coverings and flooring are declining [23]. For more information and health effects of stabilisers, flame-retarders, please see Chapter 3. 

The first step in calculating the E[NPV] in our example is to estimate (predict) the health effects of implementing the cable system, and then as the second step to determine the effect on the expected cash flows. The perspective taken is the society s viewpoint. The estimated cost of implementing the cable system in all Norwegian schools is about 150 million.
