Abstract:		"1,3-Butadiene is a carcinogenic compound that can be emitted to the atmosphere from several sources, such as the combustion of organic matter or traffic. However, petrochemical industry is one of the main origins of this compound. Several campaigns (2013-2017) were conducted in twelve Catalan urban areas to determine 1,3-butadiene concentrations in outdoor air, five of which were close to Tarragona petrochemical region. 1,3-Butadiene was dynamically sampled in multi-sorbent bed tubes (Carbotrap, Carbopack X and Carboxen 569) using portable pump equipment. The analysis was performed by automatic thermal desorption coupled with capillary gas chromatography/mass spectrometry detector. El Morell, Perafort and Puigdelfi, located near petrochemical facilities, were the most impacted locations, with average concentrations up to 15+/-33, 33+/-41 and 27+/-39mugm(-3), respectively. Maximum 24h concentrations of 125mugm(-3) were observed in Puigdelfi. However, 1,3-butadiene average and maximum concentrations in the Tarragona petrochemical region diminished significantly (p
