Abstract
The main purpose of the study was to propose the index of air pollution risk
potential Kp, to prove its acceptability and to demonstrate the results of its
application in a case study of the Tohoku district, Japan. Kp reflects climatic
conditions, which are typical for a given area and determine both accumulation
and dispersion of pollution in the atmosphere. Important applications of the
index Kp are urban planning, industrial location in relation to sensitive areas and
air quality management. The results of an index application can be easily
interpreted, the number of the elements taken into account is quite small,
however, it reflects the basic factors of the air pollution risk potential.
Keywords: air pollution, risk potential index, climatological analysis, weather
appearance distribution.
1 Introduction
The worldwide evidence on airborne particulate matter and its impact on public
health consistently shows adverse effects to exposures that are currently
experienced by populations in both developed and developing countries. The
epidemiological evidence shows impacts following both short-term and longterm
exposures. Air pollution is caused by both natural and man-made sources.
Major man-made sources of ambient air pollution include industries,
automobiles, and power generation.
The pollution levels at any place and time represent balance between the rates
of emission from their sources and the rate at which they are removed from the
atmosphere [1]. The assimilative capacity of the atmosphere determines the
dilution and dispersion of the pollutants. From the other hand, air pollutants can
