Assurance of Lead in Dust Wipes utilizing Field Analytical Technology Presented by U.S. Natural Protection Agency\'s (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) and Office of Research and Development (ORD) and the Department of Energy\'s (DOE) Oak Ridge National Laboratory (ORNL)Slide 2
Background Environmental Technology Verification Program Early 1990s - Need for ecological innovation confirmation distinguished Slow rate of advancement; poor U.S. markets Lack of validity of new advances Inertia of framework, hazard avoidance of buyers and permitters Burgeoning worldwide market EPA starts ETV in October, 1995Slide 3
ETV Objectives Provide sound execution information for business ecological advances to help merchants in offering imaginative advances, buyers in settling on choices to buy creative innovations, and controllers in settling on allowing choices with respect to natural advances.Slide 4
ETV Successes 240 Verifications, 78 conventions to date Vendor request proceeds – more than 100 innovations in testing/assessment, more than 100 applications pending Increasing financing from merchants and others 805 Stakeholders in 21 bunches Commendations from EPA science and strategy admonitory sheets Supports administrative and intentional Agency, other Federal and state programs Growing global intrigue New part in country security confirmationsSlide 5

Getting to ETV Outcomes Measuring yields to results Outputs Outcomes Number of conventions and confirmations Value set on ETV by merchants in offering and advancing innovation Value to potential buyers; impact of ETV on buy choices Use of better advances; diminished emanations in view of ETV Reduced presentation; decreased hazard on account of ETV Improved wellbeing/ecological quality in light of ETVSlide 13
Overview of Environmental Technology Verification Process Statisticians Project Officers Developers Technology designers investigate randomized specimens under field conditions. Tests are gathered, homogenized, named, and amassed for appropriation. Physicists Stakeholders Experimental Plan Product is report and confirmation articulation.Slide 14
Lead in Dust: Rationale for Performance Verification " Childhood lead harming remains a noteworthy preventable natural medical issue in the United States." - Centers for Disease Control and Prevention "Kids are most as often as possible lead harmed by family unit lead paint clean." - Massachusetts Dept of Public HealthSlide 15
Selection of the Most Appropriate Material to Test Technical board organized momentum industry requirements for assessment of field advancements for recognition of lead as: DUST PAINT SOIL Greatest needSlide 16
Fundamental Issue: Can Field Analytical Technology be Used to Facilitate Home Reuse Following Remediation?Slide 17
Why "tidy wipes" versus "mass clean"? Wipe examining gauges surface lead stacking g of lead per unit zone Risk-based tidy lead stacking benchmarks built up in light of tidy wipe inspecting Testing under the NLLAP is confined to tidy wipes. Promptly accessible ELPAT tests with confirmed fixations "Certifiable" examples of known substanceSlide 18
What were the administrative drivers for this tidy wipe testing? ETV tests give data on potential pertinence of field advances for leeway testing. Significance to leeway levels † 40 g/ft 2 stories 250 g/ft 2 window ledges 400 g/ft 2 window troughs Applications Clearance testing Risk appraisal † Identification of unsafe levels of lead, Final Rule, 1/5/01, 40 CFR 745.65Slide 19
How did we land at this trial outline? EPA AIHA HUD NIST NIOSH Technical Panel RTI Massachusetts ORNL VENDORSSlide 20
How did we land at 160 specimens? Taken a gander at all of the documented ELPAT tests; determinations in view of fixation and number of tests accessible Requested recently arranged specimens to concentrate on specific clearances levels (40, 250, 400 g) Implemented factually adjusted plan of four imitatesSlide 21
Determining the Number of Blank Samples to Evaluate False Positive Error Rate Confidence in the gauge of the false positive mistake rate increments as more clear examples are assessed.Slide 22
Attention to Clearance Levels Clearance levels Four recreate tests broke down for each test level.Slide 23
Testing Venues Focused on Where the Interest LiesSlide 24
Two Very Different Analytical Techniques Verified Portable X-beam fluorescence Portable anodic stripping voltammetrySlide 25

Anodic Stripping Voltammetry for Determination of Lead Pb(II) is decreased to Pb(0) by holding potential at cathodic incentive for brief period; Pb evaluated with anodic potential scope, measuring current for oxidizing Pb(0) to Pb(II) and stripping it from strong terminal. Anodic stripping voltammograms for the example and two standard increases of 50 ppb Pb(II). Statement potential = - 600 mV; testimony time = 1 min.; calm time = 10 sec. S.W. recurrence = 15 Hz; step potential = 4 mV; S.W. adequacy = 25 mV Electrochemical cell utilizes a working (W), reference (R), and auxillary (A) terminals in tube shaped tube with teflon top.Slide 27
Anodic Stripping Voltammetry Advantages Low capital cost Disposable material Very high example throughput Disadvantages Generates little measures of compound wasteSlide 28
X-Ray Fluorescence Exposing metallic materials to high vitality x-beams invigorates discharge of electrons the energies of which give data concerning the character of the metal being referred to.Slide 29
X-Ray Fluorescence Advantages Non-dangerous investigation Produces no substance squander Good specimen throughput Disadvantages High capital cost May require radiation source permitSlide 30
