Emission of toxic organic microcontaminants from ship's engines: first measurements on three cruising ships

This work was undertaken within the framework of Lloyd's Register's Marine Exhaust Emissions Research Programme. Phase II of this research programme [] evaluated exhaust emissions from ships in service under steady state and transient modes of operation and incorporated measurements of CO, CO2, 02, SO2, NOa and hydrocarbons on board eight ships. Additional measurements of heavy metal and organic micropollutant emissions were undertaken on three of these vessels. The organic micropollutant measurement exercise is reported herein. The purpose of the investigations reported here is to get a first impression of the emissions of organic microcontaminants from ship engines under "real world" conditions, at sea as well as on inland waterways. The work was also meant to find out whether more elaborate investigations Íìre needed or should not have priority. We will describe here in short the reasons for the investigation and for the choice of the substances measured. For each topic only one reference will be given, selected from the voluminous scientific literature.
