Airborne metal concentrations in the shipyard environment

Protection against corrosion in the shipyard isa source of airborne particles. From October 1996 to september 1997 samples of suspended particles ( 1 site) and dustfall (6 sites)were collected in thre vicinity of the repairs shipyard situated in the Martinšćica Cove, east of the city of Rijeka, Croatia. Collected samples were analysed for lead, cadmium, iron, zinc and copper.Though annual mean concentrations of suspended particles, lead and cadmium kept bellow the guideline values, the metal contents were generally higher then values measured in the city centre. The annual mean, as well as monthly amount of dustfall at the site next to the shipyard zone exceeded the national limit value, indicating considerable pollution of this area with coarse particles. The annual mean of lead in dustfall exceeded the guideline value at the same site.
