title: [Contents of heavy metals, nitrate (V), and nitrate (III) in fruits of elderberry and black chokeberry depending on harvest site and vegetation period].
abstract: Lead, cadmium, nitrate V and nitrate III contents were determined in elderberry and black chokeberry fruits harvested in Lublin region. Samples were taken from areas that were potentially exposed and not exposed to pollution. Fruits analyzed in 2003 and 2004 harvested from area exposed to pollution were characterized by higher lead concentration (0.043-0.098 mg kg(-1) fresh mass and 0.048-0.081 mg kg(-1) fresh mass, respectively) than those collected from potentially not polluted area. Levels of tested metals in fruits harvested from both areas in 2004 were fairly similar to those from 2003. However, cadmium content in all collected fruits from both areas (in both vegetation periods) appeared to be high and much exceeded its permissible value (0.03 mg kg(-1) fresh mass). Levels of nitrate V was low and similar in fruits harvested in both seasons from both areas not exceeding 3.4 mg kg(-1) fresh mass. Content of nitrate III was also low and oscillated within the range 0.68-0.89 mg kg(-1) fresh mass.
