The annual amount of cigarette butts discarded onto streets and sidewalks in the areas of bars and nightclubs in Bogota was determined by analyzing a random selection of 5 of the 27 nightlife areas registered in the city. Cigarette butts in each zone were counted Tuesday to Saturday from the evening until early hours of the next day, with 2 hours between counts and 4 simultaneous replicas of each count. The data obtained was analyzed through Dixon’s Q Test for detecting and removing outliers. Concentration of littered cigarette butts was calculated per sampling area. The value peak was located between 9 p.m. and 10 p.m. from Tuesday until Friday, and about 11 p.m. on Saturday. The greatest and second-greatest generations of cigarette butts by day were Friday and Saturday, respectively, which corresponds to the days of greatest influx of customers to these types of establishment. Annually, 94.9 million cigarette butts (16 tons) are thrown away in Bogota to the streets and sidewalks of the areas of pubs and nightclubs, which represents between 13 and 19 percent of the cigarettes consumed in the city. This represents an alarming environmental impact, as smoked cigarette butts can lead to leachate of toxic heavy metals and harmful substances into urban water resources, affecting its quality.
