Venice ship pollution drops

(ANSA) - Rome, January 15 - Air pollution caused by the presence of cruise liners in the waters around Venice is falling despite an increase in their size and number, the national research centre (CNR) said Thursday.
    The reduction is due to the use of green fuel, added CNR.
    The findings are contained in a study conducted in conjunction with the University Ca' Foscari and published in the magazine Atmospheric Environment'. "The impact of passenger traffic on the concentration of atmospheric particles in the Venice area is falling thanks to the use of green fuel," the study said.
    Local and national authorities have both expressed concern about the presence of crusie liners around the lagoon city, accusing them of causing structural damage to fragile buildings and of harming the delicate ecosystem.
