Outline of Final Research Achievements

With regard to status of trace element exposure on dogs and cats in houses, it suggested that the rare metal elements such as Ag, In, Sn and Bi were derived from hause dust. Pet foods were shown the major source of As and Hg. The other 21 elements (Li, Mg, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Se, Rb, Sr, Mo, Cd, Sb, Cs, Ba, Tl, Pb)were derived from the both sources. Lead concentration in the house dust from Tottori city was lower than that from Kanto area. Therefore, Pb exposure to dog and cats in Tottori city may be lower than that in Kanto area.
In further study, Elucidation of the exposure levels and distribution rate of trace elements from daily intake is needed.
