Chromium and nickel concentration in roadside unwashed wine grapes and leaves is considered as a function of the distance from the suspected source, an isolated straight road. The analyses were performed with electrothermal atomization in a graphite furnace. The decrease in the concentration of the element can be described by means of a three-parameter exponential function c = A + (B - A)exp(- Cd) which allows the determination of the asymptotic level far from the emitting source (c8) and the pollution level (c0) at the edge of the road (d = 0). Least-squares nonlinear regression gives the estimation of the parameters A, B and C. The results indicate that an effect is detectable up to a distance of about 50 m. |
