A few days ago, an "air environment patrol" consisting of 108 pigeons was officially put into operation in the coking area of the iron-making plant in Baowushan, China. It is reported that the pigeons are very sensitive to the oxygen content in the air. The formation of this team is to use the characteristics of the pigeons to assist in real-time monitoring of the environment and air quality of the plant. The picture shows the pigeons are “patrolling” in the coking area.
