Abstract: A questionnaire was used to survey the knowledge and attitude of senior managers toward dioxins at five waste incineration plants and seven coking plants. A field survey was performed to verify dioxin control practices at two of the waste incineration plants and one of the coke plants. All the respondents at the waste incineration plants claimed to be knowledgeable about dioxins and had a proactive attitude toward dioxin control. The field survey verified the implementation of various dioxin control measures at their plants. However, the coking plants| respondents were ignorant about dioxins. This study reveals that dioxin emission policies have had a significant effect on industrial practices and knowledge. The differences in economics between the two sites have also contributed to the disparity in their respective knowledge levels. Finally, the paper gives the corresponding recommendations on how to further improve the level of dioxin knowledge and control practices in China.

Keywords: knowledge; attitudes; practices; dioxins; waste incineration industry; coking industry; China; environmental pollution; dioxin control; dioxin emissions.
