A comprehensive assessment on bioavailability, leaching characteristics and potential risk of polycyclic aromatic hydrocarbons in biochars produced by a continuous pyrolysis system

Xiuli Shen et al.

Summary: The study assessed the potential risks of PAHs in biochars produced by a continuous pyrolysis system, finding that total PAHs concentrations exceeded standards and posed a potential carcinogenic risk when biochar application rates were high. Despite low percentages of bioavailable PAHs, the study highlighted significant concerns regarding potential health risks and phytotoxicity in biochars produced through continuous pyrolysis systems.

Formation behavior of PAHs during pyrolysis of waste tires

Wenwen Ye et al.

Summary: This study investigated the formation behavior and distribution of PAHs from the pyrolysis of waste tires. The results showed that PAHs were mainly concentrated in pyrolysis oil, followed by the gas phase, and their content was very low in the solid phase. The study also determined the formation mechanisms of PAHs in waste tires and proposed strategies for reducing PAHs formation and emissions.

Exploratory study of polycyclic aromatic hydrocarbons occurrence and distribution in manure pyrolysis products

I Adanez-Rubio et al.

Summary: The distribution and characteristics of EPA-PAH in pig manure-derived products change significantly with temperature during pyrolysis. To obtain biochars that meet international standards, it is recommended to use feedstocks with lower EPA-PAH concentrations.

Formation pathways of polycyclic aromatic hydrocarbons (PAHs) in butane or butadiene flames

Tingting Zhang et al.

Summary: The study investigated the reaction pathways from phenyl radicals to PAHs through addition reactions with C2H3 and C4H4, utilizing the G3 method to calculate rate constants and evaluating the influence of different additions on reaction rates. The improved model showed effectiveness in promoting PAH formations, with the C4H4 addition pathways being particularly beneficial for PAH formation in butane flames.
