Air pollution from traffic, ships and industry in an Italian port

Abstract

In the present study, the levels of NO x , primary and secondary formed particulate matter (PM10, PM2.5) originating from the intensive commercial and industrial activities within the port zone of Ancona (Italy) were analysed. The data have been evaluated, calculating by a Weibull distribution approach, the hourly, or using a recoded time, statistics of the pollutants concentrations and meteorological parameters measured in an area situated in a zone of influence of the harbour area. This gave the opportunity to study the dependence of the processes on the local scale as well as the impact of the harbour area on the urban scale. The highest concentrations of PM generally occurred in the harbour area whereas the NO 2 was found to be higher in the urban area. The pollutant transport from the harbour and related to the local dispersive ventilation capacity can become important in episodic situations even in the facing urbanised area.

Assessment of PM2.5 Patterns in Malaysia Using the Clustering Method

“…Sinkemani et al (2018) and Khalili et al (2018) indicated that PM2.5 derives from fuel burning, vehicular exhaust, and some industrial activities, while Khan et al (2016) found that motor vehicle emissions, secondary inorganic aerosol, and coal-fired power plants are the predominant sources of PM2.5. PM10 and PM2.5 also originate from industrial and intensive commercial activities (Fava and Letizia Ruello, 2008). Li et al (2020Li et al ( , 2021 suggested that airborne dust events contributed to high PM2.5 concentrations in Middle Eastern countries such as Kuwait, Iraq, Iran and Saudi Arabia.…”
