Blood equipment parameters

Table 10-5 gives the equipment parameters used for the practical determination of VOCs. A blank chromatogram of an untreated blood sample is shown in Fig. 10-7. 

Hematological Effects. Routine blood parameters (hemoglobin, erythrocyte, leukocyte and thrombocyte levels) measured in 11 hexachloroethane workers did not differ from those of the controls (Selden et al. 1994). Plasma hexachloroethane levels in these workers, who wore protective equipment, were 7.3 + 6.04 pg/L at the time of the hematological analysis and 0.08 0.14 gg/L before production resinned (Selden et al. 1993). Mild skin and mucous membrane irritation were reported in the exposed group, suggesting that exposure may have been through either the inhalation or dermal routes of exposure. 

ISFET based systems have been developed at different laboratories [91 -93] using a planar or three dimensional set up. Such systems which are equipped with micropumps and valves are able to detect ions and other interesting chemical parameters (Fig. 4). Different approaches have been made in the detection of ions and diluted gases. Microarrays for measuring pressure, temperature, pH, 02 and C02 were realized using silicon technology and a hybrid set up of the different components [94]. Blood gas measurements with integrated pH, 02 and C02-electrodes have been tested in real samples [95].
