“…This corroborates that PAHs carried into the lung by biochar fine particles are still toxic to lung cells, and their cytotoxicity can be predicted based on their bioaccessibility in lung liquids. This finding is particularly important for assessing the human-health risks of fine particles released from field-aged biochar, in that bioaccessibility of contaminants bound to these particles may be significantly different from that of freshly bound contaminants (e.g., due to increased extent of irreversible adsorption 40 ) and can be difficult to predict.…”

Biochars are widely used as soil amendments and are major sources of agricultural dusts. Inhalation of biochar fine particles can increase the exposure of respiratory systems to mutagenic and carcinogenic polycyclic aromatic hydrocarbons (PAHs) that are bound to the materials during pyrolysis of biomass, but the specific mechanisms are elusive. Here, we show that biochar fine particles enhance the intracellular transfer of benzo(a)pyrene (a model PAH) into the J774A.1 macrophage via the “Trojan-horse” mechanism; i.e., the endocytosed benzo(a)pyrene-bearing particles act as a vector to deliver benzo(a)pyrene into the cells. Notably, biochar particles are found to serve as a reservoir that continuously releases benzo(a)pyrene into the lung fluids. Thus, benzo(a)pyrene bound to biochar is available to the neighboring cells such as lung epithelial cells (tested with A549 cells), even without apparent endocytosis. The aryl hydrocarbon receptor activation tests and in vitro bioaccessibility assays further corroborate these findings, in that benzo(a)pyrene carried into the lungs by biochar fine particles is still toxic to lung cells, and the cytotoxicity can be predicted based on the bioaccessibility in lung liquids. This work unearths the cell-specific risk pathways via which biochar fine particles break respiratory defense systems by serving as both contaminant vector and reservoir.

“…Recientemente el negro de carbono proveniente de la gasificación del aceite crudo de los fondos de refinería, fue acondicionado para adsorber colorantes, mostrando una gran capacidad de adsorción [2]. Los materiales de ingeniería resultan ser una fuente alterna para el tratamiento de metales traza, de ahí la importancia de este trabajo para elaborar un material a partir de la pirolisis de llantas post-consumo [3,4,5].…”
