are the excessive use of chemicals in agricultural (S. Savci 2012), domestic waste
(Nyenje et al. 2013), livestock and municipal wastes (Ali et al. 2014), agrochemicals
(Wimalawansa and Wimalawansa 2014), and petroleum-derived products (Pinedo
et al. 2013). Soil pollution also results from atmospheric deposition from smelting
(Gunawardena et al. 2013) and transportation (Begum et al. 2011). Generally, there
are two types of soil pollution, which is natural and manmade soil pollution, which
includes former factory sites, inadequate waste and wastewater disposal,
uncontrolled landfills, excessive application of agrochemicals, spills of many
types, etc. Soil pollution can be divided into six types based on the source of
pollutant (Fig. 8.1).
