RESEARCH ITEM A01
Evaluation of Aerosol Formation and the Emission Sources
Research Outline
To evaluate aerosol impacts on human health and plants, introduce control
technology to
the emission sources, and formulate a reduction strategy, the following
must be
comprehensively studied: (i) characteristics of the emission sources,
and physical and
chemical behavior of the aerosols in the atmosphere; (ii) biological and
medical influences;
and (iii) integrated quantification of the source–receptor relationship based on the
achievements of the foregoing two studies. However, to date, we have not
clarified the
entire picture of secondary particle formation from precursors in the
atmosphere because
the formation mechanism is a complex nonlinear system consisting of various
factors. In
addition, measuring the characteristics of the source–receptor relationship
(the emissions
and impact) should not be limited to individual regions or countries but
considered on an
international scale to solve the pollution at a regional level, as well as a transboundary level,
through a socio-economic lens. This is done because the anthropogenic
sources are
associated with global economic activities and globalization induces the
economy–environment linkage, which creates a hidden emission structure. In this
research, we focus on the emission characteristics of aerosols and the
precursors,
reactions of the precursors relevant to subsequent aerosol formation and
the formation
mechanism of secondary particles. In addition, we aim at creating an innovative scientific
area with new research development by mutual sharing of the findings of
each planned
research group, reflection of the achievements of other studies, and adoption
of a
socio-economic perspective to evaluate the emission sources.
The main concerns are (i) evaluation of emission characteristics of aerosols and their
precursors (both anthropogenic and of plant origin) in Asian regions and
(ii) elucidation of
the reaction mechanism of the precursors and formation process of secondary
particles in
various ambient environments. Furthermore, (iii) evaluation of indirectly induced load or
impact potential in other countries as well as one’s own in accordance
with the economic
activity of the anthropogenic sources (industrial sector) in each country
will be performed
by combining quantified source–receptor relationships and input–output
analysis.
