The application of sewage sludge in sugar cane fields should represent the most sensible economic option for its disposal in Mauritius. However from the environmental viewpoint, the practice will need careful control because of the possible presence of organic pollutants in the sludge. These organic pollutants were characterized in sludge collected on 4 October 2000 at Cité Kennedy treatment plant, (a week after its release into the drying pond) and on 6 November 2000 at Saint Martin treatment plant. Sewage sludge and effluent from Saint Martin have in addition been further sampled on a daily basis during two one-month periods (October to November 2001 and September to October 2002) and analyzed. Sludge samples taken monthly from the two sites showed no detectable levels of the generally reported prioritized pollutants, namely polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzo-p-furans (PCDFs), polychlorinated biphenyls (PCBs) and polynuclear aromatic hydrocarbons (PAHs). However 16 PAH compounds have been identified at trace levels, in sewage sludge sampled daily over the period October to November 2001 at Saint Martin treatment plant. In samples where PAHs have been identified, pyrene and fluoranthene were the most prominent compounds. | |
