In this regard, the constant air quality measurements were mainly preferred
as the first step. With this approach based on the detection of air pollutants
in the outdoor air, the limit values determined for human health and
environmental protection are compared with the measurement results. Air
quality index calculations are made to classify the air quality such as good,
moderate, sensitive which can be easily understood by the public.
Fixed air quality measurements, which have a fairly high installation
and operating cost, have been supported by rapidly increasing indicator
measurements and modelling applications in recent years. Air quality
modelling applications feature with their high spatial representations,
ability to determine the impact of pollution sources with sensitivity analyses,
representing impact of various scenarios. In particular, with the “eularian”
approach, which includes the impacts of all sources, it is aimed to calculate
the inhaled air quality at the most representative level possible, taking into
account atmospheric reactions and transfers. Modelling applications with data
verification according to international standards are used as an important tool
in air quality management.

2. Regulations on Air Quality Management

The theme of air quality management, similarly, is among the first to be
addressed in an internal legislation in Türkiye. The “right to live in a healthy
and balanced environment” defined in the Constitution is regulated by
broader measures and provisions along with the Environmental Law No.
2872. Environmental problems were addressed and the relevant regulations
to prevent these problems were referred to in the development plans. The
first regulation published with the foresight of “air quality protection”, which
was already included in the internal legislation, was prepared by focusing on
industrial activities among the sources that cause air pollution. Subsequently,
becoming a party to international environmental conventions and protocols
have accelerated the process of rapid development of the administrative
and technical infrastructure related to air quality, along with the emerging
conditions both on a global scale and in Türkiye. In this scope, the organizational
structure and administrative regulations have been implemented on the basis
of monitoring, evaluating and managing the air quality both to prevent the air
pollution nationally and to follow up the impacts and results of air pollution
transport on an international scale.
