Air Pollution From Traffic, Ships And Industry
In An Italian Port

Abstract
In the present study, the levels of NOx, 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 NO2 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.
Keywords: PM10, PM2.5, NO2, harbour area, urban air.
1 Introduction
Ancona is an Italian town surrounded by a busy sea and hilly streets, with a port
for agricultural and industrial goods, traffic and passengers, and for fishing
boats. Mineral and vegetable dust coming from the intensive commercial and
industrial activities on vegetable seeds such as soybean, sunflower and
castorbean add to the gaseous Volatile Organic Compounds (VOC), SO2 and
NOx from heating and ships sailing around the harbour. The urban area is
characterized by high population density and economic development. The
resulting pollutant emissions place an increasing pressure on the air quality of
this area. Whereas in the past the major reasons for poor air quality were
