“…Ecological risk assessment is a tool that allows evaluating the impact of chemical pollutants on ecosystems (Huang et al 2019), used by researchers to assess the state of the soil environment due to the long-term accumulation of heavy metals (Mirzaei et In Peru, mining activity and mining environmental liabilities (effluents, emissions, waste produced by abandoned and inactive mining operations) are sources of the contamination of aquatic ecosystems, soils, air, vegetation and a permanent and potential risk to ecosystems, such as La Oroya (Chang Kee et al 2018, Loayza-Muro 2016). On the other hand, agricultural practices are sources of the heavy metal contamination associated with the use of fertilizers and agrochemicals, the farmers in the Junín region use these products to improve the production of their Andean agricultural products such as native potato (Solanum tuberosum), olluco (Ullucus tuberosus) , mashua (Tropaeolum tuberosum) and oca (Oxalis tuberosa), and these products constitute the basic food of the Andean population, due to their nutritional value as food and usefulness as natural medicine (Del Aguila Lopez 2018).…”

Soil is exposed to heavy metals that are associated with the anthropogenic activities, and is currently an environmental and food safety problem. The concentration and source of heavy metals in soils, the level of contamination and the potential for ecological risk in high Andean ecosystems were evaluated. The soil samples were collected from the surface part in which Andean crops were sown and the concentration of As, Cd, Pb, Fe and Zn was quantified. The concentrations of heavy metals in soils did not exceed the threshold of the national and international standard, while As, Pb and Zn exceeded the values of the background. The contamination factor (CF) values showed a high level of contamination for As and moderate for Pb and Zn. The geoaccumulation index (Igeo) values showed that As had the highest load of accumulated pollutants in soils by anthropogenic contribution. A moderate degree of contamination (CD) was found in 61.5% of the sampling sites. The potential ecological risk index (RI) showed that the soils of the study area presented a moderate to low potential ecological risk, and As was the main pollutant in high Andean soils. As, Pb and Zn occurring in high Andean soils mainly originated from human activities such as agricultural practices, whereas Fe mainly originated from the parent material of the soil. The effects of the use of organic and inorganic fertilizers on the accumulation of heavy metals in and Andean agricultural products must be analyzed and verified to protect the health of the inhabitants and the environment.

“…The risk of the rural region is higher than that of the central urban area. The farmland area located in the northwestern part of the rural area is susceptible to a certain degree of heavy metal enrichment due to various factors, such as sustainable modern agricultural irrigation, pesticides, fertilizers [44], and concentrated in the first-level construction of mainly residential areas near the Jinyin Lake. While in the central urban area, large-scale vehicles and heavy industries are few, and the environmental quality is high.…”

AbstractIn this study topsoil samples were collected from 57 sites of Dongxihu District which is a typical Chinese urban–rural combination area, to analyze the causes and effects of 6 heavy elements. (Ni, Pb, As, Cu, Cd, and Hg) Pollution of Enrichment factor, multivariate statistics, geostatistics were adopted to study the spatial pollution pattern and to identify the priority pollutants and regions of concern and sources of studied metals. Most importantly, the study area was creatively divided into central urban, semi-urbanized, and rural areas in accordance with the characteristics of urban development and land use. The results show that the pollution degree of potential ecological risk assessment is Hg>Ni>Cu>As>Cd>Pb, and semi-urban regions> city center> rural areas. Results based on the proposed integrated source identification method indicated that As was probably sourced from agricultural sources (33.99%), Pb was associated with atmospheric deposition (50.11%), Cu was related to industrial source 1 (45.97%), Cd was mainly derived from industrial source 2 (42.97%) and Hg come mainly from industrial source 3 (56.22%). The pollution in semi-urban areas in urbanization need more attention.

“…With the industrialization and urbanization process, TEs released from anthropogenic source are increasing, including discharge of industrial and municipal wastes, storms, run-offs, dry deposition, mine discharge, waste incineration, application of pesticides and fertilizers, sewage irrigation and transportation, and other diffused sources [1,[5][6][7][8][9][10][11]. The environmental medias, including water [10,[12][13][14], sediment, soil [3,4,[15][16][17][18][19][20][21][22][23], air particles [15] can be contaminated.…”

Trace Metals in the Environment - New Approaches and Recent Advances

Trace elements migrate among different environment bodies with the natural geochemical reactions, and impacted by human industrial, agricultural, and civil activities. High load of trace elements in water, river and lake sediment, soil and air particle lead to potential to health of human being and ecological system. To control the impact on environment, source apportionment is a meaningful, and also a challenging task. Traditional methods to make source apportionment are usually based on geochemical techniques, or univariate analysis techniques. In recently years, the methods of multivariate analysis, and the related concepts data mining, machine learning, big data, are developing fast, which provide a novel route that combing the geochemical and data mining techniques together. These methods have been proved successful to deal with the source apportionment issue. In this chapter, the data mining methods used on this topic and implementations in recent years are reviewed. The basic method includes principal component analysis, factor analysis, clustering analysis, positive matrix fractionation, decision tree, Bayesian network, artificial neural network, etc. Source apportionment of trace elements in surface water, ground water, river and lake sediment, soil, air particles, dust are discussed.
