Résumé : |
The leather processing industry is known to be associated with the generation of liquid waste with high total dissolved solids (TDS), in particular salinity. In part I of the present study, S. portulacastrum was used for accumulation of NaCl present in tannery wastewater and in part II of the work, the harvest plant was reused for preservation of hides and skins. In the present investigation, S. portulacastrum is being used as a phytoremediant for the removal of NaCl in tannery wastewater discharged open lands containing TDS levels of 12,300 ppm for a period of 15 months (April 2008 – June 2009), at pilot scale in a commercial site in Tamilnadu state of India. The TDS levels of the soil in terms of NaCl were reduced from 12,300 to 2700 ppm by harvesting Sesuvium portulacastrum for 15 months. An average of 77% of Na+ and 63% of Cl- was absorbed by the plants during the fifteen months of harvesting. Maximum accumulation of Na+ and Cl- was observed during the month of August’08 and minimum level of absorption resulted during the period September’08 to December’08. The phytoremediation capacity of the plant was dependent on the climatic conditions. The lower values of salt absorption are attributed to heavy rainfall in these regions resulting in lower availability of salt for accumulation by the plant. The results of the present work indicate that S. portulacastrum can be used for phytoremediation of sodium chloride contaminated soils of tannery wastewater treated lands. |
