“…Since the US EPA methodology is recommended by the Royal Decree 9/2005 for assessing risk at contaminated sites, it is very often applied in Spain (Nadal et al, 2007, Nadal et al, 2016Ordóñez et al, 2011Ordóñez et al, , 2013Peña-Fernández et al, 2014;Rovira et al, 2012Rovira et al, , 2015.

“…It should be noted that although there are many examples of the US EPA risk assessment methodology application in Spain and worldwide, they do not address segregating non-carcinogens by primary target organs or systems and deriving target organ/system-specific hazard indices (Nadal et al, 2007, Nadal et al, 2016Ordóñez et al, 2011Ordóñez et al, , 2013Peña-Fernández et al, 2014;Rovira et al, 2012Rovira et al, , 2015Xu et al, 2016).…”

“…RfD is an estimate of daily exposure that will probably have no adverse effect on the human population (Smith 1996). SF relates exposure to the probability of having a carcinogenic effect (Peña-Fernández et al 2014). Both RfD and SF are expressed in milligrams per kilogram per day.…”

Geochemical characterisation of surface waters, topsoils and efflorescences in a historic metal-mining area in Spain

Purpose Mining activities generate large amounts of wastes that may contain potentially toxic elements (PTE), which, if released into the environment, may cause air, water and soil pollution long after mining operations have ceased. This paper describes the environmental relevance of efflorescences, topsoils and surface waters from the abandoned mine of Sierra Minera of Cartagena-La Unión, SE Spain. The exposure of the population to arsenic and the associated risk were also assessed. Materials and methods A total of 10 topsoils and surface waters and 11 efflorescences affected at varying degrees by mining activities were studied. The total potentially toxic element content (As, Cd, Cu, Fe, Pb and Zn) was determined in all samples. In addition, the mineralogical composition of solid samples was determined by X-ray diffraction and some efflorescences were also analysed using a scanning electron microscopy-energy dispersive X-ray spectrometer. Finally, an arsenic-intake risk assessment was carried out, both as regards carcinogenic and non-carcinogenic effects and considering the total and the bioaccesible As content. Results and discussionThe study area is heavily polluted as a result of historical mining and processing activities, during which time great amounts of wastes were produced, characterised by a high PTE content, acidic pH and minerals resulting from supergene alteration. The supergene mineralogical assemblages include soluble metal salts, mainly sulphates, iron hydroxysulphates and iron oxyhydroxides, all of which form ochreous precipitates. Topsoil samples showed risk values and hazard quotients higher than the reference levels, particularly for children. In the efflorescences, these values were lower but still unacceptable. Conclusions The efflorescences are of significance for monitoring purposes because they are involved in cycles of retention release of hydrogen ions, sulphate and potentially toxic elements. In addition, in a semi-arid climate, such as the study area, these minerals contribute to our understanding of the response of the system to episodic rainfall events. In general, it was observed that the arsenic in collected samples represent a potential risk for human health through ingestion.

“…Urban environments are vital for human health and sustainable development, and globally, more than 50% of the world population now live in urban areas (Statista 2016;Peña-Fernández et al 2014). Urban rivers in rapidly developing regions are often severely impacted by uncontrolled population growth and lagging infrastructure development (Singh et al 2010;Enger et al 2012).…”

Antibiotic resistance genes (ARGs) in urban rivers are a serious public health concern in regions with poorly planned, rapid development. To gain insights into the predominant factors affecting the fate of ARGs in a highly polluted urban river in eastern China, a total of 285 ARGs, microbial communities, and 20 physicochemical parameters were analyzed for 17 sites. A total of 258 unique ARGs were detected using high-throughput qPCR, and the absolute abundance of total ARGs was positively correlated with total organic carbon and total dissolved nitrogen concentrations (P < 0.01). ARG abundance and diversity were greatly altered by microbial community structure. Variation partitioning analysis showed that the combined effects of multiple factors contributed to the profile and dissemination of ARGs, and variation of microbial communities was the major factor affecting the distribution of ARGs. The disparate distribution of some bacteria, including Bacteroides from mammalian gastrointestinal flora, Burkholderia from zoonotic infectious diseases, and Zoogloea from wastewater treatment, indicates that the urban river was strongly influenced by point-source pollution. Results imply that microbial community shifts caused by changes in water quality may lead to the spread of ARGs, and point-source pollution in urban rivers requires greater attention to control the transfer of ARGs between environmental bacteria and pathogens.
