In the present study, polycyclic aromatic hydrocarbons (PAHs) toxicity of lignite burning was investigated. Results showed the emissions of benzo [a] pyrene, benzo [a] anthracene, Fluoranthene, and dibenz [ah] anthracene were the dominant substances contributing to the PAHs potential human toxicity impact. By contrast, the substances of Naphthalene, Acenaphthene, Acenaphthylene had the most important contributing to the overall PAHs emissions. These results indicate that high PAHs emissions are not necessarily results to high health impact. The health toxicity generated from lignite burning are significantly affected by the air input volume and the diameter of used lignite. The lowest PAHs emissions and highest health impact caused by PAHs were observed when air input is 2 m3/kg-lignite and 2.5m3/kg-lignite, respectively. In addition, an increasing tendency of PAHs toxicity with an increase in diameter of lignite for both emission and impact were observed.

Life Cycle Impact

So far, there are major weaknesses in applying existing life cycle impact assessment characterization models to metals and more specifically to Aluminum-based products, which can lead to biased estimates of damage. To estimate the damage of polycyclic aromatic hydrocarbons (PAHs) in aluminum production sites, this study applies a life cycle assessment for pre-training electrolytic aluminum production in China. Results showed approximately 46% impact of the "average PAHs" was overestimated than existing life cycle impact assessment model (Impact2002+). Results also demonstrated the feasibility and the potential significance of including worker exposure to PAHs. Recommendations are presented to consider and compare both indoor (worker exposure) and outdoor emission of PAHs, differentiating the impact between various PAHs. These improvements are crucial for the future development of impact assessment methods that lead to comparable results between organic and inorganic substances.
