“…Most of the analyzed elements were below the values of prevention, but many were exceeding the QRV, which characterizes soil contamination. The QRV reflects the average natural content of the elements, indicating situations of non-contamination (HUGEN, 2010;KABATA-PENDIAS, 2011;SUPPI, 2018). Contents of Co, Cr, Cu, Mn, and Ni were higher than the QRV in urban gardens with spatial variation, which is evidenced by the standard deviation.…”

Urban environments are contaminated in many ways with persistent organic and inorganic pollutants as a result of anthropogenic activities, endangering human health and natural resources. The objective of the present study was to evaluate the soil contamination by cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) in 10 vegetable gardens of urban schools located near or on Botucatu sandstone outcrops of Guarani Aquifer in the urban areas of Lages, Santa Catarina, Brazil. In each garden, three soil samples at each position (in the soil immediately outside and the soil in the garden) were collected at a depth of 0-20 cm. The ISO 11466 method was used to extract the metals. Inductively coupled plasma optical emission spectrometry was used to quantify the elements and certified materials to evaluate the quantities (SRM 2709a - San Joaquin Soil - NIST). To evaluate the data, principal component analyses and cluster analyses were performed. The cluster analysis for the evaluated metals showed that the highest contents of elements were reported in three gardens. Values above the prevention value defined by resolution no. 420/2005 of the National Council for the Environment -Conselho Nacional do Meio Ambiente (CONAMA) - were reported for cobalt in one garden and copper in three gardens; thus, these areas were categorized as Class III areas. Principal component analysis explained 74.7% of the data and showed the enrichment of some elements within gardens.

“…To quantify Mn, the USEPA 3050B method in a digester block was used, determining the levels by optical emission spectrometry with inductively coupled plasma source (ICP OES) (Suppi, 2017). While for the Cu and Zn contents determination, 0.75 g of samples were kept in contact, in a digester block, with 0.5 mL of H2O and 7.0 mL of aqua regia solution (sample opening) under 90 ± 5°C for 120 min.…”

The aim of this study was to evaluate the spatial variability of Cu, Zn and Mn in non-anthropic soils in the Santa Catarina state, using ordinary kriging and ordinary cokriging models. The Cu, Mn and Zn contents were taken from the database of the Department of Soils and Natural Resources of the State University of Santa Catarina. The geostatistical methods of ordinary kriging and ordinary cokriging were applied to fit the theoretical models to the experimental semivariograms. The model choice with the best fit was based on the parameters of Average Square Root, Average Standard Error, Akaike Criterion and Spatial Dependency Index. For ordinary kriging the Gaussian model (R² 0.998) explains the spatial variability of Cu, while the circular model describes the variations of Mn (R² 0.894) and Zn (R² 0.991). For ordinary cokriging, the exponential model describes the behavior of trace elements versus land elevation. Geostatistical methods are effective in the spatializing of Cu, Mn and Zn contents in non-anthropic soils in the Santa Catarina state. Finally, land elevation does not show a linear relationship with the trace elements levels, which are concentrated in the western region, correlating with the source material.

The presence of trace elements in the soils, above its natural concentrations, can indicate anthropogenic contamination. Therefore, knowing the natural level of trace elements contents in soils is extremely important in monitoring and remediating contaminated areas. The Brazilian National Environment Council (CONAMA) determines that the states and the Federal District establish the Quality Reference Values (QRV), based on the natural levels of inorganic substances content in soils. Thus, this study aimed to determine the QRV of barium (Ba), cadmium (Cd), nickel (Ni), copper (Cu), zinc (Zn), chromium (Cr), lead (Pb), manganese (Mn) and cobalt (Co) for soils from Santa Catarina. For such, the natural content levels of Cu, Zn, Cr, Pb, Ba, Cd, Ni, Co and Mn were obtained for 43 representative profiles from the state. The natural content and the Quality Reference Values determination for soils from Santa Catarina complied with that requested by the current legislation. The QRV (mg kg-1) was determined based on the 75th percentile (upper quartile) and it was evident, due to the differences among the source materials in SC soils, the need in keeping it by soil groups with similar physical and chemical characteristics, in order to reduce the error possibility in future inspections.

Resumo A presença de elementos-traço nos solos acima das concentrações naturais pode indicar contaminação antrópica. Sendo assim, o conhecimento dos teores naturais de elementos-traço dos solos é de extrema importância no monitoramento e remediação de áreas contaminadas. O Conselho Nacional de Meio Ambiente (CONAMA) determina que os estados e o Distrito Federal estabeleçam os Valores de Referência de Qualidade (VRQ), baseados nos teores naturais de substâncias inorgânicas nos solos. Dessa forma, este trabalho objetivou determinar os VRQ de bário (Ba), cádmio (Cd), níquel (Ni), cobre (Cu), zinco (Zn), cromo (Cr), chumbo (Pb), manganês (Mn) e cobalto (Co) para solos de Santa Catarina. Para tanto foram utilizados os teores naturais de Cu, Zn, Cr, Pb, Ba, Cd, Ni, Co e Mn obtidos para 43 perfis representativos do estado. Os teores naturais e a determinação dos Valores de Referência de Qualidade para solos de Santa Catarina obedeceram ao preconizado pela legislação vigente. Os VRQ foram determinados com base no percentil 75 (quartil superior) e devido às diferenças entre materiais de origem nos solos de SC, viu-se a necessidade de manter os VRQ por grupo de solos com características físicas e químicas semelhantes, a fim de reduzir a possiblidade de erros em futuras fiscalizações.
