The levels of 16 polycyclic aromatic hydrocarbons (PAHs) were determined in 24 soil and 12 wild chard samples collected in Tarragona County (Catalonia, Spain), an area with an important number of chemical and petrochemical industries. Samples were also collected in urban/residential zones and in presumably unpolluted sites (control samples). In soils, the(More)
Background, aim and scope In 2005, a comprehensive comparison of life cycle impact assessment toxicity characterisation models was initiated by the United Nations Environment Program (UNEP)–Society for Environmental Toxicology and Chemistry (SETAC) Life Cycle Initiative, directly involving the model developers of CalTOX, IMPACT 2002, USES-LCA, BETR, EDIP,(More)
The concentrations of polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), polychlorinated biphenyls (PCBs) and polychlorinated naphthalenes (PCNs) were determined in air samples collected at four sampling sites located in two zones of Barcelona (Spain): near a municipal solid waste incinerator (MSWI) and a combined cycle power plant (3 sites), and at a(More)
In recent years, fuzzy-logic-based methods have demonstrated to be appropriated to address uncertainty and subjectivity in environmental problems. In the present study, a methodology based on fuzzy inference systems (FIS) to assess water quality is proposed. A water quality index calculated with fuzzy reasoning has been developed. The relative importance of(More)
Zinc and copper levels were determined in serum and urine of 434 subjects living in an industrial and an agricultural area of Tarragona Province, Spain. Zinc and copper concentrations were related to a range of factors such as sex, age, blood pressure, and drinking and smoking habits. Geometric mean serum zinc and copper concentrations were, respectively,(More)
In 2005, the concentrations of various metals and organic pollutants were analyzed in soils collected in different areas of Tarragona (Catalonia, Spain), where an important chemical/petrochemical complex is located. The levels of seven elements (As, Cd, Cr, Hg, Mn, Pb and V), as well as those of polychlorinated biphenyls (PCBs), polychlorinated naphthalenes(More)
Composting is a good alternative for the treatment of organic waste. However, an important amount of hazardous agents such as bioaerosols and volatile organic compounds may be released during the process. Therefore, the presence of microbiological and chemical pollutants emitted to air may mean a risk for the health of composting plants workers. We here(More)
OBJECTIVES To determine blood and urine concentrations of a number of metals and organic substances in workers at a hazardous-waste incinerator (HWI) 1 year after regular operations in the facility, and to compare these concentrations with the baseline levels. METHODS The employees were divided into three groups according to their workplaces. Plasma(More)
Mercury concentrations were determined in scalp hair of 233 school children aged 6-16 years. The study was carried out in three communities (Flix, Tarragona and Tortosa) from Tarragona Province (Southern Catalonia, Spain). The influence of the variables place of residence, age, sex, fish and seafood consumption, number of dental amalgam fillings, hair(More)
The concentrations of a number of metals were determined in the brain, bone, kidney, liver, and lung of 20 autopsied subjects who had lived, at least 10 years, in the neighborhood of a hazardous waste incinerator (HWI) in Tarragona (Catalonia, Spain). Results were compared with those obtained in 1998 (baseline survey) and previous surveys (2003 and 2007).(More)
