| Summary: | Indirect soil pollution by heavy metals and organics may occur when sewage sludge is used as fertilizer. It is essential to define the natureand amounts of pollutants contained in sewage sludge in order to assess environmental risk. Here, we present results from a one-year monitoring of herbicides (glyphosate, diuron and atrazine) and their major degradates in sewage sludge sampled from three wastewater treatment plants and one composting unit in the vicinity of Versailles, France. The concentrations of these compounds were determined, as wellas these of the surfactant nonylphenol. We demonstrated the presence of glyphosate and aminomethylphosphonic acid at the mg kg1 (drymatter) level in all samples. Diuron was detected at the lg kg1 (d.m.) level, whereas its degradate and triazine compounds were below thelimits of quantification. Nonylphenol amounts were higher than the future European limit value of 50 mg kg1 (d.m.). |
