1. SPOTLIGHT ON THE LELAND LEGACY® PUMP FROM

2. THE LELAND LEGACY PUMP Provides answers to particulate
sampling problems
High flow rates
24+ hour run times
More contaminant mass
Increased sensitivity
Meaningful data

3. U.S. EPA REGULATIONS FOR PARTICULATE MATTER
Regulations for total
suspended particulate
(TSP) have been
replaced with standards
for PM10 and PM2.5.
PM10 - referred to as coarse particulate matter
PM2.5 - referred to
as fine particulate matter

4. PUBLIC HEALTH CONCERNS FROM FINE PM
Increase in respiratory symptoms and related hospital visits for illnesses
Asthma and chronic bronchitis
Premature death

5. THE NATIONAL ACADEMY OF SCIENCE
Issued a mandate to the EPA to begin monitoring microenvironments (personal exposures)
of PM to obtain better epidemiological data of the actual health effects

6. WHY SAMPLE MICROENVIRONMENTS?
Traditional stationary ambient PM monitors are poor estimators of the actual exposures to susceptible subpopulations.
Traditional stationary ambient PM monitors do not permit researchers to assess the health effects of PM on vulnerable individuals.

7. UNIQUE CHALLENGES SAMPLING PM INDOORS
Enhanced sensitivity is required since mass concentrations are low.
Small, quiet samplers are required for sampling individuals in microenvironments.

8. THE MICKEY LELAND NATIONAL URBAN AIR TOXICS RESEARCH CENTER
Funded the development of a sample pump and a personal impactor
Recognized the need for technology to address PM concerns indoors
SKC received the grant for the sample pump!

15. APPLICATIONS FOR EXPOSURE ASSESSMENTS
USING THE LELAND LEGACY SAMPLE PUMP

16. PM IN INDOOR AIR USING THE SIOUTAS IMPACTOR
Developed by researchers at the University of S. California to collect data on the relationship between outdoor and indoor PM levels and to assess personal exposures.
Allows for measurement of mass, particle size, and chemical composition.

17. SIOUTAS PERSONAL CASCADE IMPACTOR
Four impaction stages
and after-filter:
2.5 to 10 µm
1.0 to 2.5 µm
0.5 to 1.0 µm
0.25 to 0.5 µm
< 0.25 µm
SKC Cat. No

18. ENVIRONMENTAL TECHNOLOGY VERIFICATION
U.S. EPA Environmental Technology Verification (EPA-ETV) is a program designed to accelerate acceptance of new, improved technologies through performance verification.
The SKC Leland Legacy Pump with the Sioutas Impactor received EPA-ETV verification.

19. SAMPLE ANALYSIS SIOUTAS IMPACTOR

Gravimetric analysis
CHEMICAL SPECIES
See EPA IO-3 for a variety of methods including AA, XRF, ICP, proton-induced X-ray emission spectroscopy, and neutron activation.

20. PM IN INDOOR AIR SINGLE-STAGE IMPACTORS
Method IP-10A in the U.S. EPA Compendium of Methods for Indoor Air specifies the use of a personal single stage impactor for particulates.
The method describes the Personal Environmental Monitor (PEM) available from SKC.
The PEM has various models for collection of PM10 or PM2.5 at 2, 4, or 10 L/min.
SKC 761-SERIES

21. LELAND LEGACY PUMP WITH THE PEM
The PEM designed for PM10 or PM2.5 at 10 L/min can be partnered with the Leland Legacy pump to enhance the amount of contaminant mass collected.

22. PM MEASUREMENTS USING THE IMPACT SAMPLER
The Leland Legacy pump can be also be partnered with the SKC IMPACT single-stage inertial impactor for collection of PM10 or PM2.5 at 10 L/min.
The IMPACT Sampler offers the advantage of pre-oiled impaction substrates.

24. DPS SYSTEM WITH THE LELAND LEGACY PUMP
The DPS System
has been widely used
by the U.S. Dept of
Defense for measuring
PM exposures of
deployed soldiers from
sand storms but also has an application for
indoor air.

25. PESTICIDES AND PCBs IN INDOOR AIR
USING SORBENT
CARTRIDGES WITH PUF
ASTM D a specifies a flow rate from 1 to 5 L/min from 4 to 24 hours
Partnering PUF sorbent cartridges with the Leland Legacy pump at 5 L/min for 24 hours can greatly improve sensitivity.
