POLLUTION MONITORING OF SHIP EMISSIONS:

AN INTEGRATED APPROACH FOR HARBOURS

OF THE ADRIATIC BASIN

(POSEIDON)

CONTRIBUTION OF SHIPS TO AEROSOL

CONCENTRATION IN EUROPE

Scientific literature and a recent

review (Viana et al., Atmospheric

Environment 90, 2014) has shown:

Lack of data in the

Adriatic/Ionian area.

Difficulty in the comparison of

data obtained with significantly

different approaches.

Maritime traffic contributes to air

pollution mainly with small

particles, however, there is no

sufficient data to provide a

clear picture of its impacts on

ultrafine and nanoparticle

concentrations.

Med Maritime COM & CAP Event – Malaga, April 13-14, 2015

OBJECTIVES AND METHODOLOGY

Quantify the impact of maritime

traffic and harbor activities on

atmospheric pollution of four

port-cities in the Adriatic & Ionian

Sea.

Identify policy gaps and support

the proposal of integrated

common strategies and future

actions for the environmental

management of harbors and the

sustainable development of coastal

cities in the area.

To consolidate a network of

communication among the local

and environmental authorities, the

research institutions and the public.

An advanced state-of-the-art

methodology is used, integrating

emission inventories, modelling and

measurements.

POSEIDON is designed for a maximum

capitalization of experiences and results

of previous projects.

Inter-comparison, identification of policy gaps, and

proposal of possible future strategies and actions

RESULTS – IMPACT ON AEROSOL

Maritime transport impacts are more important concerning small

particles. The concentration of ultrafine particles and nanoparticles

(PNC) is not considered in the European policy (yet); nevertheless it is

a better surrogate to monitor this specific source compared to PM10

and/or PM2.5.

TREND IN VENICE

Data from Venice for the summers 2007, 2009 and 2012 allowed to analyse the

trend of the primary impact of cruise ship maritime traffic on PM2.5

concentrations (Contini et al., 2015, Atmospheric Environment 102).

ship (in tonnage).

The use of low-sulphur fuel had positive effects on impact to SO2 and

PM concentrations (as a consequence of both European legislation and

local agreements). A future action could involve reduction strategies for

other pollutants like NO2 included in Air Quality Standards.
