Hexavalent Chromium Testing

Hexavalent chromium is a swallowed poison and an extremely toxic inhalant. Skin contact may cause sensitivity; it is more likely to cause genetic defects, and inhalation may be carcinogenic, posing a persistent danger to the environment. However, these are the characteristics of hexavalent chromium. Chromium metal, trivalent or tetravalent chromium do not have such toxicities. Hexavalent chromium is easily absorbed by the human body and can enter the body through digestion, the respiratory tract, skin, and mucous membranes. It has been reported that when inhaling air containing different concentrations of chromium anhydride, there are varying degrees of hoarseness and nasal mucosa atrophy. In severe cases, it can also cause nasal septum perforation and bronchiectasis. When it enters through the digestive tract, it can cause vomiting and abdominal pain. When it enters through the skin, it can cause dermatitis and eczema. The greatest harm is the carcinogenic risk associated with long - term or short - term contact or inhalation.
