Is the coating of ice blue liquid in headlights harmful to people?

The application of ice blue liquid to headlights is harmless to people. Chromium coating has good chemical stability and does not work in alkali, sulfide, nitric acid and most organic acids. Moreover, chromium plating is mostly used in machinery, and the metal chromium on the surface of chromium-plated parts is harmless. In the electroplating production process, chromium-plated products will be rinsed many times and reach the product parts, and the amount of residual chromium salt is actually very small. Metal chromium has almost no harmful effect on human body, and there is no report of industrial poisoning. Chromium entering human body accumulates, metabolizes and clears slowly in human tissues. In acid, chromium usually shows surface passivation. Once passivated, it is easily dissolved in almost all inorganic acids, but insoluble in nitric acid. Chromium is soluble in sulfuric acid but insoluble in nitric acid. In short, if it is not excessive, the harm to the human body is very small.
