Papoo AMEX Air Quality, 31 January, 2002
All asbestos air samples were all less than detectable limits. See attached tables, TEM Air Sample Results.
No asbestos bulk samples were collected because no bulk amounts of dust were visible on surfaces in the restaurant area. Bulk samples are considered asbestos containing material when they contain more than one percent asbestos.
The respirable dust (breathable) in air samples were collected from areas considered representative of the space. Respirable dust samples were collected and analyzed to show particle dust mass and the distribution of particle size. The particulate dust mass shows the quantity of particulate in the air. The particulate size distribution shows the size of the particulate in the dust collected. Particles less than 10 micrometers (10µm) can be inhaled by the lungs. Particles less than 5 micrometers (5 µm) can be inhaled deep into the alveoli of the lungs. The respirable dust mass and the distribution of particle size in air results are presented in the tables below.

Kitchen 739 < 0.1 3 8 0
Basement 1008 <0.1 2 0 0
The respirable dust mass and size distribution results indicate that the air in the restaurant at the Bar - Entrance, and Access has significant levels of dust. The EPA National Ambient Air Quality Standard for PM 10 is 50 µg/m3. The other areas of the restaurant have negligible dust levels.
The lead in air samples were collected from areas considered representative of the space. The lead in air results are presented in the table below. Papoo AMEX Lead in Air Results. 31 January 2002 Location Air Volume Liters Results µg/m 3
Bar 1,104 < 1.0
Kitchen- dining room 1,153 < 1.0
The results are all less than detectable limits. The EPA National Ambient Air Quality Standard for lead is 1.5 µg/m3. These results met the U.S. EPA National Ambient Air Quality Standard for lead and are considered safe for reoccupancy.
Polynuclear aromatic hydrocarbons (PAHs) were collected because PAHs are produced through
