It can appear of lead line in the gingival margin (mainly on the anterior teeth), the so-called "lead color"-the skin exhibits soil gray. The dry lead nitrate can be subject to decomposition at around 205 ~223 while a temperature of 100 is enough to trigger the decomposition of wet lead nitrate. You can select and customize services for peak efficiency, quality, and accelerated innovation. All water-soluble lead salts should be dissolved in water and converted to lead carbonate or oxides, which are safer to handle. Early symptoms of lead intoxicatin via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc. Lead(II) nitrate is associated with interesting supramolecular chemistry because of its coordination to nitrogen and oxygen electron-donating compounds. There are lead vapor, nitrogen oxide gas and lead nitrate existing during the production process, these substances are toxic so the equipment should be closed and the production environment should be well ventilated.
