Abstract

Protozoa: A Method for Monitoring of the Morphofunctional Disorders in Cells Exposed in the Cell Phone EMF Uskalova DV, Igolkina YV, Sarapultseva EI. Intravital Computer Morphometry on Protozoa: A Method for Monitoring of the Morphofunctional Disorders in Cells Exposed in the Cell Phone Communication Electromagnetic Field. Bull Exp Biol Med. 2016 Aug;161(4):554-7. doi: 10.1007/s10517-016-3459-2. Abstract Morphofunctional disorders in unicellular aquatic protozoa - Spirostomum ambiguum infusorians after 30-, 60-, and 360-min exposure in electromagnetic field at a radiation frequency of 1 GHz and energy flow density of 50 μW/cm(2) were analyzed by intravital computer morphometry. Significant disorders in morphometric values correlated with low mobility of the protozoa. The results suggested the use of intravital computer morphometry on the protozoa for early diagnosis of radiation-induced effects of the mobile communication electromagnetic field, for example, low mobility of spermatozoa. Excerpt In 2003 sanitary epidemiological regulations and Sanitary Regulations and Standards 2.1.8/2.2.4.1190-03 were introduced in Russia. These regulations set up the most stringent in the world maximal allowable values for energy flow density (EFD) - 10 μW/cm2 at a frequency of 900-1800 MHz for whole-body absorbed energy flow (SAR0 of 44 mW/kg) [5]. These standards are based on observations carried out with participation of few volunteers and in model experiments on warm-blooded animals, cultured cells, lower animals, and plants [13]. It should be noted that communication network operators use several technologies and wireless communication standards simultaneously, as a result of which the mean EMF levels in the Moscow region increased by an order of magnitude higher than the allowed values [2]. ncbi.nlm.nih.gov
