التحليل العاملي للتلوث بالأملاح المغذية في مجرى شط العرب في مدينة البصرة و علاقتها ببعض المتغيرات البيئية

Abstract EN

This study aims to assess the environmental risk of contamination with nutrients in the Shatt al-Arab River and its canals within Basra City, and to identity the possibility of benefiting from the technique of factor analysis in determining the nature of the factors affecting these pollutants and the degree of their relationship to the environmental variables.

About 28 water samples were collected over four different seasons of 2016, and a laboratory and field testing was carried out within the measurement procedures used for nitrite, nitrate, phosphate and silica indicators, as well as temperature, conductivity and turbidity parameters.

The study showed a significant increase in the concentrations of nutrients within the studied sites, mainly due to the sources of pollution in wastewater, domestic sewage and agricultural discharge, and this indicates their potential environmental risk.

It also shows that the factor analysis of the results of the study is useful in identity the factors that make up the root of the problem and the role of the variables in determining the hierarchy of the most affected sites within the available data, and it was found that the correlation coefficient between the factors and variables reveals the nature of the strength of the relationship between them, which indicates that the variables can It plays a role in controlling both the concentration and severity of pollutants.
