Barium nitrate, Ba(NO3)2, and barium chlorate Ba(ClO3)2, are used most often to produce green flames, serving both as the oxidizer and color source. Barium chlorate can produce a deep green flame, but it is somewhat unstable (and acid sensitive) and can form explosive mixtures with good fuels. Barium nitrate produces an acceptable green color, and it is considerably safer to work with due to its high decomposition temperature and endothermic heat of decomposition. Barium carbonate, BaCO3, is another possibility, but (similar to strontium carbonate stated above) it must be used in low percentage due to its effectively pyrotechnically inert anion, CO32−.

Exposures to barium nitrate by ingestion or inhalation cause poisoning. The symptoms include, but are not limited to, ringing of the ears, dizziness, irregular and elevated blood pressure, blurred vision, irritation to the respiratory system, tightness of muscles (especially in the face and neck), vomiting, diarrhea, abdominal pain, muscular tremors, anxiety, weakness, labored breathing, cardiac irregularity, and convulsions. Poisoned workers also suffer from kidney damage, cardiac or respiratory failure, tremors, convulsions, coma, and possibly death. Prolonged periods of exposure to barium nitrate is known to cause damage of the liver (anemia and possibly methemoglobinemia), spleen, kidney, bone marrow, and the CNS.

According to the study’s findings, barium (Ba) concentrations were higher in industrial areas than in agricultural or residential areas (mean: 335.5 mg/kg, maximum: 1966.5 mg/kg; mean: 34.46 mg/kg, maximum: 100.62 mg/kg; and mean: 34.11 mg/kg, maximum: 98.55 mg/kg) were the permissible limit of 500 mg/kg was surpassed in some samples from industrial locations. Higher amounts of barium have been found in industrial locations, which can be accredited to the use of barium compounds or oxides in a variety of industrial processes (Kresse et al., 2007). For fireworks to have a green color, barium nitrate is employed (Russell & Svrcula, 2008). Barium titanate is used in electro-ceramics (Wadhawan, 2019) and mineral barite is used as an chemical in oil well drilling muds.
