Lettuces and onions were grown in pots in a glasshouse, in mini-plots, 1 m × 1 m, outside that glasshouse and in a market garden on the same soil amended with 0, 1, 3 and 9 t ha−1 dried sewage sludge from a treatment plant that serves the semi-ind

To evaluate twenty sludges from different places in Australia for disposal on arable land, these sludges were extracted with (a) HNO3 to determine the ‘total’ contents of some heavy metals and other elements; (b) a solution containing DTPA to det

Some difficulties were met when low levels of Cd and Pb were estimated in plant samples in this laboratory by atomic absorption spectrophotometry (AAS). A modified procedure, based on methyl isobutyl ketone (MIBK) extraction of the metal complexes wi

Results of pot experiments depend much on the environmental conditions under which they are conducted and on “personal factors”; such as the choice of the type of pots, rates of fertilisers applied, the way these fertilisers are applied, growing

Wheat grown in contaminated soils adjacent to a lead-zinc smelter contained higher concentrations of lead, zinc and cadmium than wheat grown on uncontaminated soils. The distribution of crop contamination closely corresponded to the distribution of c
