DISTRIBUCIÓN DE PLOMO EN SUELOS CONTAMINADOS EN EL ENTORNO DE UNA PLANTA DE RECICLAJE DE BATERÍAS ÁCIDAS
Total Pb, Cd, Cu, Ni and Zn concentrations and the distribution of lead in soils from a farmland near a battery recycling plant in Madrid (Spain) were investigated to establish a possiblerelationship with a recent episode of horses death that presented lead intoxication symptoms before dying.

| Sumario: | Total Pb, Cd, Cu, Ni and Zn concentrations and the distribution of lead in soils from a farmland near a battery recycling plant in Madrid (Spain) were investigated to establish a possiblerelationship with a recent episode of horses death that presented lead intoxication symptoms before dying. Total Pb and Cd levels presented a clear decrease with distance to the battery recycling plant, ranging from 5906 to 171 mg Pb/kg soil and 11.0 to 1.58 mg Cd/kg in soils from 40 to 400 m from the plant. A five-step chemical fractionation procedure revealed that lead was mainly in the non residual fractions that accounted for more than 96 % of total lead in the most polluted soils. Acidification caused by acid effluents from the recycling plant drecreased markly the pH of the soils (from aprox. 7.0 to 3.14) and increased the soil Pb extracted in the soluble andexchangeable fraction for more than 37 % of Pb total soil. |
