Abstract
This study investigates the concentrations of 17 PCDD/Fs and 12 dl-PCBs congeners in soil samples collected from industrial areas in Cartagena de Indias (Colombia) and Valencia (Spain). The aim is to assess the characteristic distribution patterns and the potential risk around cement plants within the selected locations, addressing the lack of data on PCDD/Fs and dl-PCBs in soils from the two studied areas. Soil samples were analysed using gas chromatography coupled to high-resolution mass spectrometry (GC-HRMS). The PCDD/Fs concentrations varied from 0.01 pg g−1 dw to 520.43 pg g−1 dw in Colombia and from 0.01 pg g−1 dw to 150.48 pg g−1 dw in Spain. For dl-PCBs, levels ranged from 0.03 pg g−1 dw to 1611.83 pg g−1 dw in Colombia and from 0.06 to 189.64 pg g−1 dw in Spain. Despite the differences observed in concentration terms between the two areas studied, the same pattern of congeners was observed. The hazard index (HI) values for exposure of adults and children in soil were, in overall, smaller than one (HI < 1), while the total cancer risk (TCR) values exceeded the acceptable risk value of 10−6, which indicate probable non-carcinogenic and carcinogenic risks resulting from exposure to PCDD/Fs and dl-PCBs in these areas. The ecological risk was assessed using the Contamination Factor (CF) and the Ecological Risk Index (ERI), revealing significant contamination in the studied areas.
期刊介绍:
Emerging Contaminants is an outlet for world-leading research addressing problems associated with environmental contamination caused by emerging contaminants and their solutions. Emerging contaminants are defined as chemicals that are not currently (or have been only recently) regulated and about which there exist concerns regarding their impact on human or ecological health. Examples of emerging contaminants include disinfection by-products, pharmaceutical and personal care products, persistent organic chemicals, and mercury etc. as well as their degradation products. We encourage papers addressing science that facilitates greater understanding of the nature, extent, and impacts of the presence of emerging contaminants in the environment; technology that exploits original principles to reduce and control their environmental presence; as well as the development, implementation and efficacy of national and international policies to protect human health and the environment from emerging contaminants.
