Evaluation the soil and some vegetable plants pollution by heavy metals in weast water resulting from the Baiji refinery company

This study was conducted in Dept. of Biology laboratories on 2013 and the aim of this study to was estimate some physical and chemical characteristics of waste water resulted from the North Refineries Company / Baiji they was used to irrigate ,and estimating some heavy metals Cd, Zn, Pb, Ni, Cu, Mn and their effects on plants growth of that have been studied (celery, analyzed, tomato, sweet pepper,) located within the study area and selected region that has been collecting water samples inside Baiji refinery as station(1) and Albu Juwaree village that is located in the city of Baiji and adjacent besides to the company, it near wide agricultural areas as station(2) After estimating some physical and chemical characteristics of water,. soil, and the proportion of oil waste ,the study estimating heavy metals in samples water, solid and plants were studied as well as the assessment of (carbohydrates, proteins) in addition to the germination on those plants The results showed that the water of industrial waste led to a reduction in germination, rate results also shown that the average concentration of Cd in irrigation water was 0.025 mg/l and more than the acceptable level for WHO, while the average concentration of Ni in soil was 116 mg/kg which is more than WHO limit, results for plants show that the average concentration of Pb in all samples was more than WHO limit, it was 1.80, 1.375, 1.8, and 1. mg/kg in, celery, sweet pepper, tomato, analyzed, The Results showed that the contaminated water led to the reduction of the proportion of carbohydrates with the increase of pollution, where the least proportion of carbohydrates was at celery 20.7 mg/L also the result showed a decrease in protein concentration at pepper was 54,54 mg/L therefore the increasing of consumption for this contaminated plants by community could cause health problems in the future.
