P2.21 Adaptability to Global Climate Change by Adjusting
Car Environment against Heat Stress

Medicine, Japan); Manomaipiboon, K. (Mahidol University);
Uchiyama, I. (Kyoto University); Kabuto, M. (National Institute for Environmental
Studies)
Countermeasures to the risk of global warming are required
in running cars as common human environment. Temperature variations
are inevitable due to dynamic heat exposure even in air-conditioned
(AC) car. Unstable hot/cold air produces stress and fatigue
resulting increased accidents during summer and extreme weather.
Two cars either with or without heat insulating window film (F-car or
non-F car) were compared during highway drive using temperature
recorder, EEG and ECG, under constant AC. F car showed lower
temperature in the ceiling, rear seat, and right arm than in non-F car.
Sympathetic tone increased in non-F car drivers but not in F car
drivers, though power spectrum of EEG (PS) showed only decrease
during drive than rest reflecting subjective tension. Decreased solar
radiation may contribute to homogeneous temperature resulting
less AC load and stress to F car driver. It explains comfortable experience
of heat insulating film beyond actual heat reduction.
P2.22 Comparing the Type, Quantity, and Availability
of Risk Values Across Organizations
Wullenweber, A., Dourson, M., Maier, A. (Toxicology Excellence for
Risk Assessment - TERA), (Presented by Jacqueline Patterson)
Risk assessors throughout the world use risk values to make
important public health decisions. These risk values are developed
by a variety of organizations and may differ due to scientific judgments,
the mission of the organization, or the use of more recently
published data. Additionally, different organizations develop different
chemical priority lists and therefore, may derive risk values for different
chemicals than other organizations. This analysis used risk values
derived by Health Canada, the National Institute of Public Health
and the Environment (The Netherlands), the U.S. Agency for Toxic
Substances and Disease Registry, the U.S. Environmental Protection
Agency, and independent parties to compare trends in the type,
quantity, and availability of currently published risk values among
organizations. For example, we find that there are risk values available
from 3 or more organizations for 10 of the 20 Priority Hazardous
Substances, often with different guidance values provided. We also
find that for the majority of the roughly 600 chemicals in the International
Toxicity Estimates for Risk (ITER) database, only a single
organization has a risk value available. This analysis suggests the
importance of being able to conduct side-by-side comparisons to
both identify the availability of and to select risk values for application
in public health decision-making.
P2.23 How EPA-HHRAP Protocol Could be Useful for
Europe? A Belgian Prospective Point of View
Alexis Dutrieux (Atmpro)
The EC SEVESO Directives concern major accidental releases
of chemical compounds. « Top tier » chemical companies
have to build up together with authorities an efficient emergency
plan. ATM-PRO provides its SEVEX Tools in order to identify realistic
danger zones and build appropriate emergency response plan.
ATM-PRO performed a review of existing tools for assessing
the human health impact of chronic industrial pollution. The Environmental
Protection Agency (USA) developed a protocol called
« Human Health Risk Assessment Protocol or HHRAP ». It provides
guidance on how to conduct risk assessments for hazardous waste
combustion units. It presents a user-friendly set of procedures for
performing risk assessments including (1) a complete explanation
of the basis of those procedures, and (2) a comprehensive source of
data needed to complete those procedures.
The poster explains how « HHRAP » could be useful for Europe
as beeing complementary to accidental release « packages ».
