“…Based on correlation and PCA analyses, Cr only showed a relationship with Cu and was the only metal to show a high loading weight on PC3. The tanning industry, which was a historically abundant industry in the study area, is a known source of Cr contamination (Srinivasa et al, 2010); however, the Cr contamination levels in our study area were low compared to the other metals. Song et al (2012) reported Cr contents of 43.9e1892.7 mg kg À1 in sediments in Wen-Rui Tang River, which were similar or higher than the Cr concentrations found in this study (94.2e439.6 mg kg…”

“…In particular, electroplating, printing and dyeing, paper mills, tanning, chemical and synthetic leather are primary industries located within the study area. These factories have historically discharged non-treated industrial effluents with high concentrations of heavy metals into Wen-Rui Tang River and are considered an important metal pollution source (Srinivasa et al, 2010). In addition, the significant positive correlation of metals with OM indicates that sediment characteristics also play an important role in heavy metal concentrations and fractionation (Yu et al, 2001).…”

TitleDistribution and source analysis of heavy metal pollutants in sediments of a rapid developing urban river system. Heavy metal pollution of aquatic environments in rapidly developing industrial regions is of considerable global concern due to its potential to cause serious harm to aquatic ecosystems and human health. This study assessed heavy metal contamination of sediments in a highly industrialized urban watershed of eastern China containing several historically unregulated manufacturing enterprises. Total concentrations and solid-phase fractionation of Cu, Zn, Pb, Cr and Cd were investigated for 39 river sediments using multivariate statistical analysis and geographically weighted regression (GWR) methods to quantitatively examine the relationship between land use and heavy metal pollution at the watershed scale. Results showed distinct spatial patterns of heavy metal contamination within the watershed, such as higher concentrations of Zn, Pb and Cd in the southwest and higher Cu concentration in the east, indicating links to specific pollution sources within the watershed. Correlation and PCA analyses revealed that Zn, Pb and Cd were dominantly contributed by anthropogenic activities; Cu originated from both industrial and agricultural sources; and Cr has been altered by recent pollution control strategies. The GWR model indicated that several heavy metal fractions were strongly correlated with industrial land proportion and this correlation varied with the level of industrialization as demonstrated by variations in Chemosphere 207 (2018) 218e228 local GWR R 2 values. This study provides important information for assessing heavy metal contaminated areas, identifying heavy metal pollutant sources, and developing regional-scale remediation strategies.

RESUMENLa contaminación del aire es considerada como uno de los mayores desafíos ambientales debido a sus efectos sobre los ecosistemas y la salud humana. En este estudio se investigan los niveles de concentración y las fuentes de la contaminación por metales pesados en muestras de polvo de caminos recolectadas en varios sitios que incluyen áreas con cuatro actividades diferentes en Delhi, India: industriales, carreteras, residenciales y de uso mixto. El contenido de metales en polvo de caminos se analizó mediante espectroscopia de emisión atómica por plasma de acoplamiento inductivo. Los resultados muestran altos niveles de concentración de Ni, Cr y Pb en áreas industriales. Los coeficientes de correlación de Pearson acoplados con análisis de componentes principales revelaron que el CD, el Cr, el Ni y el Pb están vinculados con fuentes industriales en tanto que el Zn y el Cu proceden principalmente del tráfico vehicular. La contaminación en polvo de caminos se valoró a través de varios métodos: grado de contaminación, índice ecológico e índice de contaminación. El análisis de los factores de contaminación reveló que las muestras de polvo de caminos estaban contaminadas de manera considerable con Zn y Pb. Los índices de potencial ecológico indicaron la presencia de contaminación significativa por Cd y moderada por Pb en el polvo de camino, en tanto que la contaminación por Cr, Cu, Ni y Zn fue baja. El índice de contaminación de la mayoría de los metales fue mayor a 1, lo cual revela un deterioro en la calidad del polvo de caminos en Delhi a causa de las emisiones antrópicas. El grado de contaminación, el índice de potencia ecológico y el índice integrado de contaminación indican que el polvo de caminos en áreas industriales, de carreteras y de uso mixto exhiben alta contaminación por metales pesados. El polvo del camino también está contaminado de manera significativa. Evaluaciones realizadas por diversos métodos indicaron que todas las técnicas son importantes para valorar la calidad ambiental. ABSTRACTAir pollution has been considered one of the major environmental challenges because of its effect on ecosystems and human health. The concentration levels and sources of heavy metals contamination were studied in road dust samples collected from various locations including four different activity areas: industrial, highways, residential and mixed use in Delhi, India. Metal content in road dust was analyzed by inductively coupled plasma atomic emission spectroscopy. The results showed high concentration levels of Ni, Cr and Pb in industrial areas. Pearson's correlations coupled with principal component analysis revealed that Cd, Cr, Ni and Pb are associated with industrial sources whereas Zn and Cu are mainly contributed by vehicular traffic. Road dust contamination was assessed by various methods: degree of contamination, potential ecological index and pollution index. Contamination factor analysis showed that road dust samples are significantly contaminated by Zn and Pb. The potential ecological indices indicate...

“…In addition, the above elements in the upstream WLFZ had relatively higher EF values at S9 and S21, as the residential area located at S21 led to more untreated sewage discharge and the tributaries adjacent to S9 contributed heavy metals to the mainstream. In the downstream WLFZ, higher EF values for As, Cd, Pb and Zn were found at X8 and X10; these higher values could be attributed to the chemical fertilizer application in the adjacent farmlands (Srinivasa Gowd et al 2010, Zhao 1996. As for Cr, Cu and Ni, the EF values were relatively lower, ranging from 1.1 to 1.6, both in the upstream and downstream WLFZs; therefore, these metals might come from crustal materials or natural weathering (Acevedo-Figueroa et al 2006).…”

Purpose The intersections of the terrestrial and aquatic systems (water-level fluctuation zones, WLFZs) suffer from the increasing pressure of hydroelectric construction and operation. Taking WLFZs upstream and downstream of Manwan Dam (first dam completed in Lancang River) as an example, the dam operation impacts on the heavy metals in soils in WLFZs were assessed. Materials and methods In December 2011, 117 soil samples were collected in the WLFZs and infralittoral reference zones (IRZs) with respect to heavy metal (Cd, Cr, Cu, Ni, Pb and Zn) and metalloid (As) concentrations. Their concentrations were determined with the application of inductively coupled plasma atomic absorption spectrometry, ICP-AES. Enrichment factor (EF), ecological risk index (RI) and principal component analysis (PCA) were employed for element contamination and ecological risk assessment and source identification, respectively. The multivariable statistic approaches, an analysis of variance (ANOVA) and a paired-samples T test were performed in the data analysis.Results and discussion Parts of element concentrations in the upstream were significantly higher than those in the downstream and significant differences existed between the WLFZs and IRZs. No significant difference was detected between the different water elevations in the WLFZs. Compared to the soil quality guidelines, As and Cd exceeded the standard in both the WLFZs and IRZs. In addition, the water-level fluctuation during the submergence increased the enrichment degree and risk level in the WLFZs. The sources of the studied elements could be divided into natural factors and anthropogenic inputs. In addition, the submergence changed the major contaminants in the upstream WLFZs. Conclusions The results verified that dam operation had an effect on the heavy metals in the soils in WLFZs. In addition, this study proposed a useful tool (modified enrichment factor) to assess the enrichment degree caused by the water-level fluctuation. Assessing the heavy metal contamination of soils in WLFZs could be an important first step to the rational management of the dam operation.
