Particle Size-Selective-Threshold Limit Values (PSS-TLV)
Particle Size-Selective-Threshold Limit Values (PSS-TLV) :
Medicine. Expressed in three forms (a) Inhalable Particulate Mass-TLVs (IPM-TLVs): for those materials that are hazardous when deposited anywhere in the respiratory tract. Particles with m are of interest. aerodynamic diameters up to 100. (b) Thoracic Particulate Mass-TLVs (TPM-TLVs): for those materials that are hazardous when deposited anywhere within the lung airways and the m are of gas-exchange regions. Particles with aerodynamic diameters up to 25 interest. (c) Respirable Particulate Mass-TLVs (RPM-TLVs): for those materials that are hazardous when deposited in the gas-exchange region. Particles with m are of interest. aerodynamic diameters up to 10
