Traces of vanadium in substantial-temperature combustion products and solutions form droplets of molten vanadates. These assault the passivation levels on metals and induce higher temperature corrosion, which is a priority specifically for internal combustion engines. Molten sulfate and lead particulates even have this kind of outcome. DNA. Arsenic, nickel https://broadfar.com/oraco-global-trends-in-heat-not-burn-products/
