Ganesh Chaturthi (Ganesh Festival) is an Indian festival in which Lord Ganesha, son of Shiva and Parvati is worshiped. This festival is celebrated throughout India and is particularly popular in the state of Maharashtra. The festival lasts eleven days. The last day of the celebration, the statues are carried in procession to the place of their immersion by devotees. The immersion of the statues results in a significant environmental impact. The paintings that decorate the statues contain heavy metals such as mercury or cadmium. The use of gypsum in the manufacture of statues also causes the release of toxic items.
