| 1. | The respirable fraction of Earth-based analogs have serious limitations.
|
| 2. | Human exposure to respirable asbestos is a very serious concern,
|
| 3. | Venturi scrubbers achieve very high collection efficiencies for respirable dust.
|
| 4. | A second type protects users by providing clean, respirable air from another source.
|
| 5. | The gaseous oxide of azote ( the laughing gas ) is perfectly respirable when pure.
|
| 6. | The emission and accumulation of respirable suspended particulates are the major pollution threats in Hong Kong.
|
| 7. | The respirable fraction is the proportion of particles in the air that can reach the alveolar region.
|
| 8. | It points out that 2, 000 deaths in Hong Kong last year were related to respirable suspended particulates.
|
| 9. | To measure the respirable fraction of particles in air, a pre-collector is used with a sampling filter.
|
| 10. | Nuisance, inhalable and respirable dust fractions are all sampled using a constant volumetric pump for a specific sampling period.
