“…The concentrations of metals in soils collected in 2004 were similar to the levels recently found in other industrial and urban zones of Tarragona County (Nadal et al, 2004;Mari et al, 2007). Possible explanations for the differences found in metal concentrations after certain periods of time are rather complex, and could be due to a number of reasons.…”

In recent years, incineration has been demonstrated to be a commercially available technology for hazardous waste (HW) disposal (Richter and Johnke, 2004). However, because of the potential adverse effects of toxic emissions, waste incinerators are still an important cause for concern for the public. In spite of that, compliance with current EU emissions has vastly reduced the probability of adverse health effects (Glorennec et al., 2005). With respect to metals, a number of studies have shown that these elements are emitted by industrial, medical and municipal waste incinerators (Schumacher et al., 1997; Rimmer et al., 2006). Filter ash is an especially problematic residue because it contains high metal concentrations (Lisk et al., 1989). After combustion in modern HW incinerators (HWIs), metals contained in HW are mainly collected in bottom and fly ash, with only small quantity of metals being discharged from the stack as particulate matter or vapor (Jung et al., 2004). However, the atmospheric emission of these elements is a matter of concern.

“…Plants grown in polluted soils can accumulate potentially toxic elements at high concentrations, and cause a serious risk to human health when plant-based food stuffs are consumed (Cui et al 2004;Fytianos et al 2001;Kisku et al 2000;Nadal et al 2004;Sridhara et al 2008).…”

The aim of the study was to investigate influence of an industrialized environment on the accumulation of heavy metals in agricultural soils. Seventy soil samples collected from surface layers (0-20 cm) and horizons of five selected pedons in the vicinity area of petrochemical complex in Guangzhou, China were analyzed for Zn, Cu, Pb, Cd, Hg and As concentrations, the horizontal and vertical variation of these metals were studied and geographic information system (GIS)-based mapping techniques were applied to generate spatial distribution maps. The mean concentrations of these heavy metals in the topsoils did not exceed the maximum allowable concentrations in agricultural soil of China with the exception of Hg. Significant differences between land-use types showed that Cu, Pb, Cd, Hg and As concentrations in topsoils were strongly influenced by agricultural practices and soil management. Within a radius of 1,300 m there were no marked decreasing trends for these element concentrations (except for Zn) with the increase of distance from the complex boundary, which reflected little influence of petroleum air emission on soil heavy metal accumulation. Concentrations of Zn, Cu, Pb, Cd, Hg and As in the five pedons, particularly in cultivated vegetable field and orchard, decreased with soil depth, indicating these elements mainly originated from anthropogenic sources. GIS mapping was a useful tool for evaluating spatial variability of heavy metals in the affected soil. The spatial distribution maps allowed the identification of hot-spot areas with high metal concentration. Effective measures should be taken to avoid or minimize heavy metal further contamination of soils and to remediate the contaminated areas in order to prevent pollutants affecting human health through agricultural products.

“…These trace metals can be released from numerous anthropogenic activities such as fossil fuel combustion, automotive industries, leakage of metal-containing motor oils, tanneries, municipal waste disposal and building (Barltrop 1979;Kelly et al 1996;van der Sloot et al 1996;Tossavainen and Forssberg 1999;Councell et al 2004;Nadal et al 2004, Wong et al 2006, which are currently encountered in the basin,. The concentrations of the heavy metals analyzed in this study ranges were frequently above their associated freshwater chronic hardness adjusted criteria for aquatic life (EPA 2006) (Fig.…”

Spatial and Temporal Ion Dynamics on a Complex Hydrological System: The Lower Luján River (Buenos Aires, Argentina)

2009

The interplay of the geochemistry of the lower stretch of the Luján River is analyzed with its natural geomorphology (basin features), local hydrometeorology (tidal regime and ''sudestada'' events) and the impact of polluted tributaries. Major ions, dissolved heavy metals and limnological variables were analyzed using multivariate techniques. The water quality of the mainstream of the Luján River, flowing through urbanized and industrialized areas is strongly and positively influenced by the input of the Paraná River through deltaic watercourses and is negatively impacted after receiving the discharge from polluted watercourses. The longitudinal spatial variations evidenced major discontinuities in the Lower Luján Basin, showing clearly the riverine and the deltaic water influenced zones. Seasonal variations were also marked and were either temperature driven or associated with the estuarine cycle and the ''sudestada''.
