“…The concentrations of PCBs in the Volturno River have been analysed and compared with the concentrations found in other rivers and estuary in the world, to understand the degree of contamination due to these pollutants. As showed in Table 2, PCBs in samples from the Volturno River were similar to those found in the Hangzhou Bay, China [33], in the Chenab River, Pakistan [34], in the Portuguese coast, Portugal [35] and in Chenab River, Pakistan, by [36]. The concentrations were higher than those presented in the Tokyo Bay, Japan [37], in the Chao River, China [38], in the Haizhou Bay, China [27], in the Daliao River Estuary, China [39], in the Shuangtzaizi Estuary, China [9], in the Chaohu Lake, China [28], in the Yellow River, China [11], in the China Sea, China [40], in the Congo River Basin, Congo [41], in the Congo River Basin, Congo [42], in the Izmir Bay, Turkey [43], in the Nador Lagoon, Marocco [44], in the Morava River, Czech Republic [45], in the Plitvice Lake, Croazia [46], and in the Adriatic Sea, Italia [47]; but lower than those found in Moscow River, Russia [48], in the Yangtze Estuary, China [10], in the Ravi River, Pakistan [49], in the Umgeni River, South Africa [50], in the Msunduzi River, South Africa [51], in the Sea Lots, Trinidad and Tobago [52], in the Panama Canal and California Coast, USA [53], in the Bedford Harbor, USA [54], in the Chiacago Ship Canal, USA [55], in the Midway Atoll, Hawaii [56], in the Portuguese Coastal area, Portugal [57], in the Rhone River, France [58], in the Huveaune River, France [59], in the Durance River and Berre Lagoon, France…”
