摘要: Abstract The leachates from 17 lysimeters containing compost of varying origin, age (3 and 12 months)., packing depths (15–50 cm) were monitored for a 2.5-year period. This paper reports on the results Na, K, Ca, Mg, Mn, Fe, Cl, SO 4 to lesser extent specific conductivity, total dissolved solids, F, B P. High initial leachate concentrations exceeding drinking water standards several-fold observed all constituents except F. Sulphate K identified as most serious pollutants ions studied but they found be less critical than N compounds organic matter previously reported in leachate. leaching constitutents increased with increasing amounts per square metre. origin affected Mg . first year released significant parts Cl only minor F P present compost.
