Managing the treatment and disposal of domestic sludge is an important activity and one that is highly regulated in many countries. After treatment, the effluent may be discharged leaving a mixture of water, organic solids and chemicals, nutrients, heavy metals, and inorganic ions. This sludge can be further treated and the resulting biosolids can then be applied to the land as a fertilizer, sent to landfill or incinerated. It is vital that the sludge or biosolids are tested and conform to regulatory levels in order to protect public health and the environment. The United States federal biosolids rule is contained in 40 CFR Part 503. The European Union Sludge Directive 86/278/EEC is expected to be revised as several Member States have enacted and implemented stricter limit values for heavy metals and set requirements for other contaminants. In this work, an Agilent 4200 MP - AES was used to deter mine major and minor elements in domestic sludge, following microwave digestion.
