Trace elements sewage

Trace elements in soils and sludges (CRMs 141R-146R 597) pp 225-232 (1998k) Chlorobi-phenyls in sewage sludge (CRM 392) pp 240-243 (1998I) Trimethyl-lead in urban dust (CRM 605) pp 274-278 In Production of Certified Reference Materials for Pollutants in Environmental Matrices. European Commission Report EUR 18157 EN, CCF Academic Press, Tarbes. [Pg.47]

The enormous difference in certified values between methods and between analytes illustrates well how much care is needed in matrix/method matching. Further evidence of the importance of matrix matching is provided by an interlaboratory study on trace elements in soil reported by Maier et al. (1983) and the certification of a sewage sludge described by Maaskant et al. (1998). [Pg.240]

The termination of sewage biosolids applications in arid soils often results in decreases in the bioavailability of trace elements. Webber and Beauchamp (1979) found a stronger statistical relationship of Cd uptake in com to the amount of Cd added in the most recent sludge application than to... [Pg.241]

Organic matter added to arid soils in the forms of sewage sludge and other solid waste is decomposed following the model C = C0 (l-e kt) + Ci (Pascual et al., 1998). The decomposition is initially a rapid process of mineralization, followed by a second slower phase. With decomposition, trace elements originally bound in organic materials are released into the soils and soil solution, and they become available to plants. [Pg.277]
