n the last, the industrial sector has been revitalized in Cuba. Specifically, the metal-mechanical industry has been extensively

used to produce parts for the sugar industry, iron and steel industry as well as other industries. Former iron and steel work

sites are significant in terms of their degree of pollution. The aim of this research was to determine the elemental composition

of PM10 and water soluble ions associated to this particle fraction at workplace atmosphere in an iron foundry. The PM10

was sampled by a low volume sampler and PM10 concentrations were collected using a filter paper. The sampling was made

during the process of molding, unmolding, and casting of iron and non-working days. The samples collected were analyzed by

the energy dispersive X-ray fluorescence technique. In the excitation, an X-ray tube of Gd operated at 6 mA/100 kV/1500 s, 8

mA/75 kV/1500 s and 17.1 mA/35 kV/840 s irradiated secondary targets of Mo, Ge and Ti respectively. The ionic species were

analyzed by ion chromatography. The results show that the highest concentrations are for Na, Mg, Al Si, S, Cl, K Ca, Fe, Cu

Zn, Sn and Pb. There are elements such as P, Ga, Ge, As, Se, Rb, Y, Zr, Cd, I, Cs and Ba whose concentration levels were below

the limit of detection and the blank limit of detection during all processes. Thirteen ions were analyzed but, only Na

are also high during non-working days.
