PCDD/F Dioxin Profile of Treated Pinus pinaster wood

引用

Journal of Environmental Protection 2016年第12期7卷 1971-1979页

作者： Miguel Cardo Lina Nunes Marta Duarte António Silva Fernando Bernardo University of Lisbon Faculty of Veterinary Medicine (FMV) Lisbon Portugal Laboratório Nacional de Engenharia Civil Departamento de Estruturas Lisbon Portugal

This work describes the treatment of Pinus pinaster wood with four different industrial wood preservatives (two anti-bluing or fungicide and two fungicide/pesticide) and the detection and quantification of the dioxin contamination profile in the wood shavings. The samples were collected from poultry liters during three contamination incidents of poultry meat. Two methods used were, both nonpressure: one by immersing the wood samples in the preservative solution and the other by impregnation of the preservative solution into the wood, with vacuum. It was concluded that there is no difference in terms of contamination profile, caused by the different industrial wood treatment preservative products in study. A clear correlation between the commercial products used in wood treatment and the contamination profile of wood shavings that have been used as bedding material in poultry production was detected.
