VANADIUM IN AN AREA JUST OUTSIDE STOCKHOLM

Vanadium is emitted to the atmosphere when fossil fuels are burned. For a recreational area just northeast of the center of Stockholm a fallout of about 20 mg/m**2. y has been calculated from measurements during December-March 1973-74. The mean value of dissolved vanadium in one of the major streams leaving the area was 2. 6 mu g/liter. The amount of suspended vanadium might be of the same order. In a runoff amounting to 200 mm/y is assumed, this means that about 1 mg/m**2. y is transported away with the runoff water, or 5% of the deposition. The rest is retained, mainly ih organic matter. This accumulation is not toxic to higher plants, but may reduce the rate of mineralization of organic matter.
