Explanation:

Barium is a chemical element with symbol Ba and atomic number 56. Because of its high chemical reactivity, barium is never found in nature as a free element. Barium Nitrate is used to produce green light. In combination with other chemicals, it can produce more colours. It is used in all light-emitting fireworks. Use of Barium (Ba) salts emit poisonous gas causing respiratory problems and may have health complications due to other health complications due to long terms exposure. But a replacement for barium nitrate is yet to be explored. In order to tackle air and noise pollution during festivals and other occasions, including weddings, the Supreme Court has mandated a series of steps to regulate the use of firecrackers based on the affidavit submitted by the Environment Ministry. Hence both statements are wrong.
