North Gujarat is a high energy-importing region with around 17 Industrial Development areas. In various edible oil refineries of this area some of the edible oil is lost and is disposed of in the soil as a waste which creates pollution of soil. The main objective of this paper is to present an analysis of soil which is contaminated with edible oil .The description in the paper is thus summarized on various parameters of edible oil contaminated soil. This pollution may disturb food chain and affect the normal flora of the soil. Keywords: Industrialization, crude oil, waste, Environmental pollution.
Rapid industrialization for sustaining economic stability, is leading to the pollution of the environment. There are around 17 Industrial Development areas in and around North Gujarat region. All these Industrial Development areas are concerned with the production of various economically important compounds such as Cereals, Oil Seeds, Isabgul, Castor, Cotton and Pulses. They are the main annual crops grown as well as like other parts of India and Gujarat, economy of North Gujarat region largely depends upon agriculture. Industrialization and urbanization are responsible for the Air, Soil and Water pollution. There are various edible oil industries also located in Industrial Development area and involved production of edible oil. The crude or unrefined oils extracted from oilseeds generally consists of free fatty acids (FFA), mono-, di-, and triacylglycerides (MAGs,DAGs, and TAGs), phosphatides, pigments, sterols, tocopherols, glycerol, hydrocarbons, vitamins, proteins fragments, trace amounts of metals, glycolipids, pesticides and resinous and mucilaginous materials among others1.The first step in producing oils for edible applications involve the separation of the oil (containing more than 90% TAGs) from other solid components of the seeds2. Generally the two methods employed for obtaining edible oil are pressing and solvent extraction. For the majority of oilseeds, this is achieved by pressing followed by solvent extraction 3. The crude oil thus obtained may be refined, bleached and de-odourised to remove pigments, objectionable odors and flavors and non-triglyceride material. It was achieved by various methods such as deacidification, neutralization, bleaching, and deodorization. 4 A significant amounts of by-products such as soap stocks, deodorizer distillates and acidic water are produced from crude oil refining processes, and these by-products are potentially harmful to the environment. Additionally; edible oil that escaped while being transferred through a pumping station to a tanker and reservoir considered as a waste and create soil pollution to some extent and thus affecting the cultivated area and normal flora of the region.
AIMS & OBJECTIVES:
The main aim of the study is to determine edible oil contamination in north Gujarat region and was achieved by analysis of edible oil contaminated soil.
MATERIALS AND METHODS:
Selection of Site
Site has been selected on the basis of the fact that numerous edible oil refineries are located in the vicinity of Industrial Development Areas of North Gujarat region which principally involved in production of various types of edible oil. Edible oils are derived from seeds of plants. Among the oilseeds cultivated in North Gujarat, from which edible oil is obtained, are groundnut, rapeseed, mustard, sesame, soyabean, and castor. The other sources of vegetable oil are palm, cottonseed, coconut and rice bran. In spite of using efficient oil recovery equipment some of the edible oil is lost and is disposed of in the soil as...
