Pesticide Residues

Analysis which identifies and quantifies the residual level of lice and fly treatment chemicals in greasy wool, semi-processed wool and wool grease. The presence of heavy metals such as Arsenic can also be determined.

Wool samples are prepared and blended at one of our Raw Wool Laboratories, then sent for chemical analysis to AWTA’s Agrifood Technology division. Any chemicals present are extracted from the wool using a proprietary process and their concentrations determined using state-of-the-art equipment.

Tests are done in accordance with the International Wool Textile Organisation method DTM59-04.

We are also looking at developing methods for detrermining residual pestcide levels in individual fleece samples.

The major chemical groups screened include Organophosphates, Organochlorines, Synthetic Pyrethroids and specific Insect Growth Regulators (Diflubenzuron, Triflumuron & Dicyclanil).  The full list of checmicals reported is shown below:
