The method of BAC action is good for disinfection, but it is harmful to humans because BAC damage bacterial cell membranes, which can induce toxicity in human cells at high doses or prolonged exposure . Absorption of BAC through the skin, lungs, or gastrointestinal tract can cause systemic toxicity, affecting many organs and systems, this can harm the liver . BAC vary in toxicity according on chemical, concentration, and exposure time. Avoiding health risks requires proper BAC handling, use, and disposal according to safety standards as mentioned before. BACs' capacity to interact with cellular components and break cell membranes is the primary mechanism by which they might cause hazardous consequences in humans. Toxic action mechanisms are described in further depth here. Because of their positively charged nitrogen atom, BAC can interact with phospholipids and proteins, which are negatively charged components of cell membranes . As a result of this interaction, the following outcomes are possible: enhanced permeability of cell membranes; hence, bacteria can clench lipid bilayers, allowing enzymes, proteins, and electrolytes to flow out of cells, causing complete disintegration and cell lysis (rupture) . Solubilizing lipids in the cell membrane, which results from BAC at greater concentrations, leads to essential cellular functions disruption when BAC bind to and block the activity of enzymes that are linked to the cell membrane .
