“…They are found in ambient air, soil, as well as surface and underground waters. Elevated concentrations of heavy metals are also observed in bottom sediments of lakes and rivers where they are accumulated and bound to organic matter (14). Toxic metals migrate in the environment freely and change their chemical form, becoming available for plants and animals at various levels of the food chain, which ends in human consumers.…”

The aim of the study was to determine the concentrations of lead (Pb), cadmium (Cd), and mercury (Hg) in the liver, kidneys, and muscles of European beavers (Castor fiber) and thus to evaluate the degree of heavy metals contamination in Warmia and Mazury region in Poland. The study was conducted on free-living beavers captured in region of Warmia and Mazury during autumn 2011. Concentrations of the elements were determined by atomic absorption spectrometry. The presence of the metals was detected in all individual tissue samples. Mean Pb and Hg concentrations were relatively low. However, the high mean Cd level, especially in the kidneys (7.933 mg/kg) and liver (0.880 mg/kg) was demonstrated. Despite the fact that region of Warmia and Mazury is considered to be "ecologically clean", the conducted studies indicate that systematic monitoring for the presence of heavy metals is necessary not only in industrialised but also in agricultural regions, as well as in natural ecosystems.

“…They originate from several sources that can contaminate soil, water and plants, and consequently, animals (Hammond and Aronson, 1964;Kuno et al, 1999;Patra et al, 2007;Reis et al, 2010;Rajaganapathy et al, 2011) and humans (Duarte and Pasqual, 2000). These sources include atmospheric deposition, farming and cattle-raising residues, fertilizers and soil correctives, agrochemicals, sewage sludge, irrigation water, urban garbage composts, and urban, industrial and mining wastes.…”

-The objective of this research was to determine the concentration of heavy metals in the blood (Pb, Ni and Cd), serum (Cu and Zn) and hair (Pb, Ni, Cd, Cu and Zn) of horses raised in non-industrial and industrial areas (with steel mill), and to verify the possibility to use these data as indicators of environmental pollution. The samples were collected during summer and winter, aiming to verify animal contamination related to environment and season of the year. Copper and Zn contents determined in the serum and Cd and Ni contents obtained in the blood indicated no contamination effects of industries. For some animals, contents of Pb in the blood were higher than those considered acceptable for the species, but without relationship with industrialization and without clinical signs of Pb intoxication. The heavy metals evaluated on the hair of horses in this study were not increased with the presence of industries, but Cu and Cd contents were influenced by the season. The contents of some heavy metals in biological components analyzed were influenced by season sampling; however, serum, blood and hair may not be suitable to indicate differences in environmental contamination between the two contrasting areas. Most part of the heavy metal contents was lower or close to the reference values for horses. Serum, blood and hair components from horses may not be effective as indicators of environmental pollution with heavy metals. Industrialization and seasons have no effects on most part of heavy metals contents from those components.

“…But the case of acute (immediate) poisoning is rare through ingestion or dermal contact but is possible [2]. The toxicity of trace metals is one of the major environmental health concerns and potentially dangerous due to bioaccumulation through the food chain [4].…”

“…Trace metals persist for a long time in the environment because they are not degradable. In addition, they are translocated to different components, thus affecting the biota [2][3][4]. The persistence of trace metals can result in bioaccumulation and biomagnifications causing heavier exposure for some living organisms that are present in the environment [8].…”

“…Contamination refers to the condition of the land or water where any chemical substance or waste has been added at the above background level. The signifies of water, air, and land pollution include an adverse health or environmental impact [2][3][4] runoff, aerial deposition of chemicals used for agriculture or industry, materials stored or dumped on the site, and contaminants in imported fill, and building demolition can also result in contamination of the soil and water that are close to residential communities [5]. Contaminants such as trace metals may be introduced into drinking water via the aforementioned activities or leached from the soil into groundwater [6].…”

Environmental contamination by trace elements is becoming increasingly important problem worldwide. Trace metals such as cadmium, copper, lead, chromium, and mercury are major environmental pollutants that are predominantly found in areas with high anthropogenic activities. Therefore, there is a need for rapid and reliable tools to assess and monitor the concentration of heavy metal in environmental matrices. A nondestructive, cost-effective, and environmentally friendly procedure based on near-infrared reflectance spectroscopy (NIRS) and chemometric tools has been used as alternative technique for the simultaneous estimation of various heavy metal concentrations in environmental sample. The metal content is estimated by assigning the absorption features of metals associated with molecular vibrations of organic and inorganic functional groups in organic matter, silicates, carbonates, and water at 780-2500 nm in the near-infrared region.This chapter, reviewed the application of NIRS combined with chemometric tools such as multiple linear regression (MLR), principal component regression (PCR), and partial least squares (PLS) regression. The disadvantages and advantages of each chemometric tool are discussed briefly.
