Causes of Soil Pollution. The major causes of soil pollution are water and air pollution, chemical waste from factories and pesticides. The most common type of soil contamination is due to the use of fertilizers or chemicals in agricultural production, such as fertilizer runoff that releases nitrates and other nutrients into surface waters or groundwater. ments (air, rain water, runoff water, surface soil, sludge and plant) of different industrial cities of Chhatisgarh states (viz., Raipur, Bhilai and Korba) was investi- gated (Patel et al. 2010a ). Water, Air and Soil Contamination. Pollution is an environmental concern for people throughout the world. One university study suggests that pollutants in the water, air, and soil cause up to 40% of the premature deaths in the world's population. The majority of these deaths occur in developing countries.. Water in many developing countries is contaminated with toxic chemicals, also known as Polluted soil becomes unfit for growing crops and plants, and is usually accompanied by water pollution. The significant causes of soil pollution are over-irrigation, usage of pesticides, dumping of sewage and garbage, deforestation and mining. The most common soil pollutants are heavy metals like lead and mercury, pesticide compounds, salt and This study reports on adsorbed metals in a fine-grained soil from a large cemetery in Northwest Ohio. Metal analyses were performed by atomic absorption and inductively coupled plasma spectrometry. This preliminary investigation revealed numerous possible sources of contamination, and the data support the need for further research. Effect on Ecosystem and Biodiversity: Soil pollution can lead to the lack of biodiversity in an ecosystem. The life of bird, insect, mammal and reptile species that live in the soil can get affected by pollution. The soil is an important habitat. 7. Contamination of Water Sources: When it rains, surface run-off carries Soil degradation may have direct impacts on water and air quality, biodiversity, and climate change [6]. Thus, it may result in a reduction in the soil's capacity to support human communities and ecosystems, and to desertification. Moreover, it can also impair the human health and threaten food and feed safety.
