The % weight of total particulate matter per cigarette after smoking was then calculated and presented in Table 1, vide infra.
Evidently, an adsorbent incorporated into the filter should reduce the amount of total particulate matter impinging on the lungs of the cigarette smoker.
The fine particles represent approximately 70% and the coarse particles account for the rest 30% of total particulate matters collected on eight stages for both incinerators.
The % yield of total particulate matter (TPM) trapped on silica per cigarette after cigarette smoking (Fig. 1a) was calculated and found to have a mean of ~2.49% per cigarette (Table 1).
On the other hand, when a small piece of the filter was carefully cut and replaced with silica (Fig. 1b), about 13% of the total particulate matter per cigarette for SM1 cigarette was retained by silica, leaving ~87% to pass through the filter while about 15% of total particulate matter per cigarette for ES1 cigarette was retained leaving approximately 85% TPM to pass through the filter (Table 2).
The average concentrations of total particulate matter in the exposure chambers were 684 and 547 mg/m, respectively.
In tunnel 2, where it was registered the highest concentration of total particulate, especially due to fractions A and B, any increase of MN was found.
For instance, precursor-constituent relationships may best be evaluated on the basis of total particulate matter (TPM), tar (TPM minus water and nicotine), or carbon monoxide yields.
The data collected from the experimental tests included brake torque, exhaust and coolant temperatures, emissions from exhaust including carbon monoxide and nitrogen oxides, and emissions of total particulate.
The OSHA standard for coke oven emissions, which went into effect in January 1977, sets a permissible exposure limit to coke oven emissions of 150 micrograms/m3 benzene-soluble fraction of total particulate matter (BSFTPM).
