The project ‘Air quality monitoring in the Port of Split Authority’ aims to establish a system for continuous air quality monitoring in one of the six ports of international economic importance for the Republic of Croatia. The project involves the installation of a fixed measuring station to monitor emissions of NO2, SO2 and PM10/PM2 particulate matter, while meteorological sensors monitor parameters such as pressure, temperature, air humidity and wind direction and speed. The aim is to ensure timely response to increased levels of air pollution and to enable the planning of effective measures to reduce emissions, thereby reducing negative impacts on human health and the environment, as well as reducing exposure to harmful substances and encouraging the sustainable development of the port authority.
