The rate of emergency room (ER) visits among children significantly increases during the relatively cool and dry conditions in the summer seasons, finds a new study. The research, published in the Plos One journal, which analysed data from the urban and rural regions of South Carolina, found that the increased emergency room visits by children is directly linked to seasonal air pollution, particularly during the relatively more cold and dry conditions in the summer and also during increased temperatures in the spring and fall seasons. The researchers also pointed out the socio-economic factors coming into play as a section of the society may not have the resources to make behavioural changes to avoid the situation.
