Experimental result is as follows:
The dry weight of transplanting the balsamine plant each several part after 4 months is as shown in table 1.
Each processed group balsamine plant dry weight of table 1
Experimental result shows: all pollute the balsamine plant gross dry weight of processed group all less than the blank group.PCBs reveals different effects to the balsamine growth table during from different concentration Pb combination.Under Pb pollutes for the 300mg/kg processing, the biomass of Pb-PCBs Combined Processing group is all greater than single Pb processed group, the existence of PCBs has promoted the growth of balsamine, it is maximum that combined pollution when wherein PCBs concentration is 50 μ g/kg is processed dry weight, be significantly higher than single Pb processed group, along with the increase of PCBs concentration, the above and below ground part dry weight of balsamine is all reducing.Under the processing when Pb pollutes for 600mg/kg, process with respect to single Pb, PCBs has promoted the growth of balsamine when concentration is 100 μ g/kg, all the other two groups of growths that then suppress balsamine, wherein the above and below ground part dry weight significant difference of processed group T7 and T8.Pollute under the 1000mg/kg treatment conditions at Pb, Pb-PCBs combined pollution processed group biomass is all less than single Pb processed group, and PCBs has suppressed the growth of balsamine, but along with the increase of PCBs concentration, balsamine above and below ground part dry weight all increases gradually.
Different parts is as shown in table 2 to the Pb cumulant in the balsamine plant body under the difference pollution is processed.
Pb is in the cumulant (mg/kg) of balsamine plant each several part under each processed group of table 2
Experimental result shows: Pb cumulant in the balsamine body is followed successively by root from high to low〉stem〉leaf, each position of balsamine increases along with the increase of Pb concentration in the processed group the Pb cumulant.But when the Pb concentration for the treatment of was identical, each position of balsamine but presented different Changing Patterns because of the difference of PCBs concentration for the treatment of to the cumulant of Pb.For root, when the Pb concentration for the treatment of was 600mg/kg and 1000mg/kg, the Pb-PCBs combined pollution was processed lower balsamine the Pb cumulant all is higher than single Pb pollution processed group, reaches maximum 279.43 and 559.77mg/kg at T8 and T11 respectively.For stem, when the Pb concentration for the treatment of was 1000mg/kg, Pb-PCBs combined pollution processed group balsamine all was significantly higher than single Pb to the cumulant of Pb and pollutes processed group, and the Pb concentration for the treatment of when being 600mg/kg situation opposite.For leaf section, be under the 1000mg/kg in the Pb concentration for the treatment of, balsamine reaches maximum to the Pb cumulant when the PCBs concentration for the treatment of is 100 μ g/kg, be significantly higher than other processed group.
Accumulation rate refers to that each position heavy metal accumulation amount of plant accounts for the percentage of whole strain plant heavy metal accumulation amount.Under difference pollute to be processed, the balsamine different parts to the accumulation rate situation of Pb as shown in drawings.Show among the figure: combined pollution processed group balsamine root presents single Pb processed group greater than correspondence generally to the accumulation rate of Pb, and namely PCBs has promoted the accumulation of Pb at the balsamine root, has reduced the ratio that Pb shifts to aerial part.
Conclusion: under Pb-PCBs combined pollution condition, balsamine has shown preferably patience and to the Pb cumulative function.In contrast to single Pb and pollute processing, the Pb-PCBs combined pollution has promoted the growth of balsamine when low concentration Pb is 300mg/kg, suppressed the growth of balsamine when high Pb concentration is 1000mg/kg, but has promoted the accumulation of balsamine to Pb; The Pb-PCBs combined pollution has promoted Pb the accumulating of plant root, and having reduced on the ground, tissue being subjected to the Pb damaging effect.Therefore, the Pb that uses in the flower plant balsamine reparation Pb-PCBs combined contamination soil has preferably potentiality.
