Assessing the Risks of Tire Burning on Human Health

Andrew Mahon, Neale Mahoney, Adrienne Moretti, Shane Murphy, Blake Rainville



Problem
Problem

  • The combustion of tires could potentially release levels of fine particulates which could adversely affect human health


Background
Background

  • International Paper Company hopes to utilize scrap tires as an additional fuel source

  • IPC plans to burn 3 tons/hour

  • IPC’s current permit

    (Title V permit) requires

    2-week test period


Background1
Background

  • Local citizens are concerned that emissions could reach toxic levels and have harmful affects

  • Vermont has filed suit against IPC to ensure a full environmental review is completed


Goal

  • To ensure that, if tire burning takes place at IPC, necessary actions are taken to reduce risks to human health


Objectives
Objectives

  • To determine recognized acceptable concentrations of particulate matter in emissions

  • To evaluate human health risks associated with fine particulate matter emitted during tire combustion

  • To evaluate mechanisms that could be implemented to reach LOAEL

  • To make recommendations on how IPC should proceed with tire burning


Burn rubber
Burn Rubber

  • Tires composed of petroleum-based products

  • Incomplete combustion produces polycyclic aromatic hydrocarbons (PAH), which condense from gaseous form to become ultra-fine PM

  • The PAH particulate

    matter is hydrophobic


Particulate matter
Particulate Matter

  • Particulate matter consists of different substances suspended in the air in the form of particles

  • PM size classifications:

    • PM10

    • PM 2.5

    • Ultra-fine


Particulate matter and health risks
Particulate Matter and Health Risks

  • PM 2.5 poses most serious known health risks

  • When inhaled, can become lodged deep into the lungs

  • Chronic exposure can

    cause respiratory

    problems, lung disease,

    and cardiovascular

    complications

(Revised Title V Permit, ENSR Corp., 2005)


Iscst3 modeling results
ISCST3 Modeling Results Pollution

  • Models show no significant human health risks from short-term exposure

  • Models do not take PM 2.5 or ultra fine matter into account


Size does matter
Size Does Matter Pollution

  • PM is only measured by mass

  • Recently the EPA found importance in measuring particulate size

  • Particulate size most important factor in selecting scrubbers


Scrubber technology
Scrubber Technology Pollution

  • IPC currently uses wet scrubber to reduce large PM (PM10)

  • Wet scrubbers do not remove PM 2.5 or smaller

  • PAH’s are hydrophobic, so wet scrubbers will not be effective


Recommendations
Recommendations Pollution

  • More thorough modeling/testing, including ultra-fine particulate matter

  • Run modeling/testing for longer periods of time to determine long-term effects on human health

  • During two-week test, quantify fine/ultra- fine PM emitted to properly assess risks


Questions
Questions??? Pollution

  • Nothing difficult, please.
