“…Deciphering the detailed mechanism of action will be beneficial since there are reports of biochar usage in agriculture and its possible tumorigenic hydrocarbon production effects. If these hydrocarbons are consumed by humans they might lead to detrimental side effects but studies suggest that the concentrations of tumorigenic hydrocarbon production during biochar applications are at low levels therefore, its usage in the agriculture seems to be safe [48,49] …”

Biochar is an organic material and high in carbon content, besides its use for energy purposes, it is also a material that serves the purpose of improving soil fertility, organic matter content of soils and removing heavy metals from water and soil. This study aims to investigate the antimicrobial effects of biochar whose beneficial effects on agricultural productivity has been proven by different studies. Scientific literature concerning the antibacterial, antifungal, and antiviral effects of the apricot seed and olive seed biochar is limited. Biochar applications may help to alter the microbial diversity by modifying biological environment either in agriculture or in animal husbandry. Moreover, biochar has been used in animal husbandry to improve animal health especially by regulating the intestinal flora and inflammation in the intestines. Hence, in our study, we investigated the effect of biochar on the growth of Aspergillus niger, Cryphonectria parasitica, Phytophthora cinnamomi, Plenodomus tracheiphilus, Enterococcus casseliflavus, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and two different bacteriophage strains. Biochar did not have any direct effect on the growth of either Gram‐positive or Gram‐negative bacteria, bacteriophages, and fungi. In order to test their direct effects on the immune cells, mammalian macrophages were used and biochar directly reduced the inflammatory cytokine levels produced by the in vitro activated macrophages.

“…PAHs are mainly formed as a result of the incomplete combustion of coal, oil, wood, and other organic compounds at high temperatures, and they widely exist in the atmosphere, sediments, and water, where people are often exposed. Various sample pretreatment procedures have been developed for the analysis of diverse PAHs in environmental samples. − However, these methods require large volumes of organic solvents and long extraction times to achieve low limits of detection (LODs) and high sensitivity.…”

Carbon dioxide (CO2) microbubbles can selectively enrich organic solutes from sea spray aerosols. Common bubbling extractions are normally followed by off-line separation/detection through methods such as mass spectrometry, chromatography, and spectroscopy. However, it is necessary to establish extractions with online separation and identification systems to improve efficiency and minimize sample loss. In this study, CO2 is used to form microbubbles in the sample solution, and trace analytes in the solution are transported to the gas phase by bubble bursting. Analytes at the liquid–gas interface are directly released into the trapping device, followed by thermal desorption for gas chromatography–mass spectrometry. For polycyclic aromatic hydrocarbons, the dependence of the extraction efficiency on various parameters has been analyzed. The method reported here provides high efficiency and minimizes the loss of trace volatiles with a better signal strength and signal-to-noise ratio than other gases. These features make the proposed method a rapid method to detect and quantify volatile/semivolatile analytes in complex liquid matrices. In addition to the preconcentration of organics, metal ions, and inorganic anions, a noticeable decrease of metal–organic compounds in the aqueous solution was shown for the first time. We finally propose a simple model of chemical partitioning in CO2 bubbling extraction of liquid samples for guiding online monitoring of trace analytes in real-world samples.

“…Biochar application increased PAHs concentration in soil which in turn increased the concentration in food crops posing a human health risk ( Wang et al., 2019d ). The PAHs content of biochar amended soils and risk of exposure is high at early stage of amendment and it is affected by initial biochar quantity and soil carbon content ( De Resende et al., 2018 ).…”
