SPOTLIGHT ON THE LELAND LEGACY® PUMP

FROM

THE LELAND LEGACY PUMP

Provides answers to particulate

sampling problems.

High flow rates

+ 24-hr run times • More contaminant mass

• Increased sensitivity• Meaningful data

U.S. EPA REGULATIONSFOR PARTICULATE MATTER

Regulations for total

suspendend 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

PUBLIC HEALTH CONCERNS FROM FINE PM

Increase in respiratory symptoms and related hospital visits for illnesses Asthma and chronic

bronchitis

Premature death

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.

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.

UNIQUE CHALLENGES SAMPLING PM INDOORS

Enhanced sensitivity is required since mass concentrations are low.

Small, quiet samplers are required for sampling individuals in microenvironments.

THE MICKEY LELAND NATIONAL URBAN AIR TOXICS

RESEARCH CENTER

Recognized the need for technology to address PM concerns indoors

Funded the development of a sampling pump and a personal impactor

SKC received the grant for the sampling pump!

APPLICATIONS FOR EXPOSURE ASSESSMENTS

USING THE LELAND LEGACY SAMPLING PUMP

PM IN INDOOR AIRUSING 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.

SIOUTAS PERSONAL CASCADE IMPACTOR

Four impaction stages

and after-filter: 2.5-10 µm 1.0-2.5 µm 0.5-1.0 µm 0.25-0.5 µm <0.25 µm

SKC Cat. No. 225-370

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.

CHEMICAL SPECIES

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

PM IN INDOOR AIRSINGLE-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

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.

PM MEASUREMENTSUSING 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. SKC Cat. Nos.

225-390 and 225-392

DPS SYSTEMWITH THE LELAND LEGACY PUMP

The Leland Legacy

pump and the IMPACT

Sampler have been

incorporated into the

Deployable Particulate

Sampler System for

PM10 or PM2.5.

SKC Cat. No. 100-3901/2

DPS SYSTEMWITH 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.

PESTICIDES AND PCBs IN INDOOR AIR

USING SORBENT CARTRIDGES WITH PUF ASTM D4861-94a

specifies a flow rate from 1-5 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.
