The Regulation also introduces a provision designed to reduce or eliminate certain sources of contamination. When the background level for an undesirable substance is exceeded Member States are required to investigate the cause of the contamination and take appropriate action. In order to ensure a harmonized approach between Member States, provision is made in the Regulation for the fixing of Action Thresholds in certain cases.
Moreover , this amending are relate to the method for determination of lead in kaolinitic clay and in feed containing kaolinitic clay, Recently , the European Union Reference Laboratory for heavy metals in feed and food (EURL–HM) have identified for a significant difference of the analytical results obtained by the application of different extraction methods between currently used for the determination of lead in kaolinitic clay and feed containing kaolinitic clay. this regulation recommend that for the determination of lead in kaolinitic clay and in feed containing kaolinitic clay, the maximum level refers to an analytical determination of lead, whereby extraction is performed in nitric acid (5 % w/w) for 30 minutes at boiling temperature. Equivalent extraction procedures can be applied for which it can be demonstrated that the used extraction procedure has an equal extraction efficiency.
