INTRODUCTION

The health effects of the pollution are caused by the exposure of the population. EXPOLIS measured the population exposures to key air pollutants in six European cities.

In the Expolis study the population exposures to the key air pollutants were measured for the first time in Europe. This was one of the most important break throughs in the air pollution related public health research in the 90's.

The pollutants studied in the Expolis are fine particulates (PM2.5), carbon monoxide (CO), the most interesting volatile organic compounds (VOCs) in the respect of environmental exposures and public health, and nitrogen dioxide (NO2). The populations studied are working age urban populations from large cities. Metropolitan area of Helsinki is the smallest of participating cities (1 million). Largest is Athens (4 million).

The Expolis field measurements were carried out 1996-97. Scientific and statistical data analyses are still going on.

EXPOLIS LOGO

The EXPOLIS study name, "Expolis" was created by Dennis Zmirou. The name comes from two stems:

  • Exp stands for exposure
  • Polis stands for a city (in greek)
The EXPOLIS logo was created by Otto Hänninen and Matti Jantunen. It features key aspects of the study:

The S-shaped curve describes the cumulative population exposure distribution. In this curve, the x-axes represents the exposure level and the y-axes is the cumulative frequency of the exposure.
The 3 different curves represent different exposure distributions in different cities or target populations.
The man and the woman on the logo stand for the human beings, the public, being exposed to the air pollutants. The ultimate aim of the EXPOLIS Study is to improve public health.
GIVING FEEDBACK TO US

The original EXPOLIS home pages were designed back in 1996-1997 by Ms MSc Paula Jantunen.
