The tars produced by PVC pyrolysis under different conditions of temperature and oxygen concentration were analysed for PCDDs and PCDFs content. The tar collected after low temperature pyrolysis (500 °C) and in reduced oxygen atmosphere (11.6% O2) had the highest PCDDs/PCDFs content. The toxicity of the tars is mainly due to the high PCDFs concentration. The most toxic compound, 2,3,7,8-T4CDD, had a contribution of only 0.5–4.4% of the total toxicity of the tar. Several hypotheses for PCDDs… CONTINUE READING
