“…Electromagnetic hazarded was considered one of the most dangerous types of pollution [1] due to the electromagnetic fields which affected the functions of cells of the body [2]. The potential health risks of radiofrequency electromagnetic fields (RF EMFs) emitted by mobile phones are currently of considerable public interest [3].…”

Objective: To investigate the effects of electromagnetic fields on some hematological parameters of Male white mice. Methods: In this study two experiments were used as short-term and long-term experiments. Short-term experiments were carried out in 80 male white Balb/c mice exposed to two types of mobile phone for a period time up to 60 min a day for 2 weeks. Long-term experiments were carried out in 30 male white Balb/c mice exposed to two types of mobile phone for a period time up to 90 min a day for a month, two months, three months. Result: The present result found that a decline in hemoglobin, hematocrit, red blood cells count, in addition to the platelets count after short and long exposure to both types of mobile phone (Alcatel, Nokia). It was observed that the average number of white cells and lymphocytes increased significantly, indicating the increase to the body's immune response to radiation. Also, when exposed to both devices (Alcatel, Nokia) for 15 minutes, the red blood cells began to take a role of formation due to an increase in the viscosity of the blood and the ability of the cells adhesion. Increased duration of exposure to 30-minute to both devices revealed disparities in the sizes of red blood cells with the appearance of a large proportion of cells with pale colors due to lack of hemoglobin. In the group exposed for 45 minutes showed clearly the influence of mobile phones on examining blood smears which observed a proportion variation in the cell sizes with the emergence of forms of abnormal forms, including pellets cleft with many areas empty of red blood cells, With increasing in of exposure duration to 60 minutes, red blood cells appeared completely different from the natural form and took the forms resembling the eye and tear that appear in the case of anemia. After three months of exposure to both types of mobile phone showed pathological changes in red blood cells where gripped the outer membrane of the red corpuscle changes and become serrated. Conclusion: Exposure to electromagnetic fields is responsible for the variations of some hematological parameters in rats.

“…Large databases have been built and statistical analyses of the magnetic fields have been performed [8][9][10][11][12][13] . These studies seemed to indicate an association between living near overhead power lines and an increase in childhood leukemia [14][15][16][17][18] . This triggered a series of similar epidemiological studies in a number of countries throughout the world, as well as many laboratory studies exploring a possible mechanism that might explain the observed association.…”

This work presents a detailed study of the underground transmission cables at 231 locations within Riyadh in order to detect and identify the source of the magnetic field in very low frequencies ELF that might be present. The magnetic field was measured parallel to the path of the cable once and orthogonal with them. The aim is to explain how it affects to the nearby houses. The magnetic field is measured in the summer and spring season. Handheld triaxial EMF magnetic field metre (TM-192, Tenmars Electronics) has been used for magnetic field measurement. The measurement of magnetic field has been carried out at a distance of one metre above the ground. It was found that the magnetic field fall within a range of 1.3-197 mG with an overall mean value of 54.7±42.2 mG. The results show that the mean values of the magnetic field in this study was far below the allowable limit set by international agencies. The results of this study have concluded without doubt that the underground transmission 18 M.A. AL-Rajhi cables constitute a source of exposure to the magnetic field, which means that the presence of net current caused the pollution. Therefore, the study recommends the importance of issuing a legislation to make the magnetic field around the underground transmission cables non-existent.

In this study, the electromagnetic waves were defined with an explanation of their physical properties and negative biological effects on humans, where the importance of research appears in defining the concept of sustainability, leading to the construction of guiding standards that help designers to reach for sustainable architecture for healthy buildings. Accordingly, the research hypothesizes that sustainable buildings are high-efficiency buildings that reduce negative impacts on the environment and human health, and are designed to be economical in resource consumption. In this study, the sources and negative effects of electromagnetic fields on human health were identified as a problem and some suggestions were presented to solve them and prevent negative electromagnetic radiations from affecting human health by setting standards for protecting buildings from the negative effects of electromagnetic radiation. The main objective of this study is to reach a set of results that enable the achievement of eco-friendly buildings that take into account human needs and health.
