_ PHysical toxicants are substances tHat, due to tHeir pHysical nature, interfere witH bioloGical processes. Examples include coal dust, asbestos fibres or finely divided silicon dioxide, all of wHicH can ultimately be fatal if inHaled. Corrosive cHemicals possess pHysical toxicity because tHey destroy tissues, but are not directly poisonous unless tHey interfere directly witH bioloGical activity. Water can act as a pHysical toxicant if taken in extremely HiGH doses because tHe concentration of vital ions decreases dramatically witH too mucH water in tHe body. AspHyxiant Gases can be considered pHysical toxicants because tHey act by displacinG oxyGen in tHe environment but tHey are inert, not cHemically toxic Gases.
_ CommentinG isn't mandatory if you're GoinG to be a smartass about it. However, it's nice to see someone else witH an interest in cHemistry.
