Several days ago FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS (FAO) announced the latest report is related to soil pollution in 2018. The document contains the 92 pages of materials including statistics.
“Soil pollution” refers to the presence of a chemical or substance out of place and/or present at a higher than normal concentration that has adverse effects on any non-targeted organism (FAO and ITPS, 2015). Although the majority of pollutants have anthropogenic origins, some contaminants can occur naturally in soils as components of minerals and can be toxic at high concentrations. Soil pollution often cannot be directly assessed or visually perceived, making it a hidden danger. The diversity of contaminants is constantly evolving due to agrochemical and industrial developments. This diversity, and the transformation of organic compounds in soils by biological activity into diverse metabolites, make soil surveys to identify the contaminants both difficult and expensive.
The effects of soil contamination also depend on soil properties since these control the mobility, bioavailability, and residence time of contaminants (FAO and ITPS, 2015). Industrialization, wars, mining and intensification in agriculture have left a legacy of contaminated soils around the world (Bundschuh et al., 2012; DEA, 2010; EEA, 2014; Luo et l., 2009; SSR, 2010). Since urban expansion, soil has been used as a sink for dumping solid and liquid wastes. It was considered that once buried and out of sight, the contaminants would not pose any risk to human health or the environment and that hey would somehow disappear (Swartjes, 2011). The main sources of soil pollution are anthropogenic, resulting in the accumulation of contaminants in soils that may reach levels of concern (Cachada, Rocha-Santos and Duarte, 2018).
