“…It is reported that peaks in the 535, 635 and 1270 nm wavelengths confirm that there is singlet oxygen in the studied solution, which emits photons of light during the transition into a basic triplet state. This conforms with the opinion stated in some papers [14,15] in which it is said that one of the reasons for a changed chemiluminescence of DNA aqueous solutions under the lowfrequency EMF influence could be the production of reactive oxygen species in water. In one article [21] it is said about doubleand single-stranded breaks in DNA solutions which occur under the influence of peroxide radicals and low-frequency EMF exposure [22].…”

“…A low-frequency EMF exposure is used to change the rate of some of important biochemical processes: repair of DNA elements with evident somatic mutations, generation of reactive oxygen species by neutrophils, change in cytokine levels etc. [3,[14][15]. A well-known manifestation of a cellular stress reaction is damage to biologically significant molecules, DNA first of all.…”

“…A well-known manifestation of a cellular stress reaction is damage to biologically significant molecules, DNA first of all. In one article [14] an opinion is presented that changes in DNA hydration shell under the influence of specific low-frequency EMF exposure leads to the restoration of hydrogen bonds, bridging and DNA repair as a whole.…”

This research was aimed to study a combined influence of a low-intensity electromagnetic field (EMF) with 5-30 Hz frequency in presence of cadmium ions on structural changes in deoxyribonucleic acid (DNA) and human seralbumin (HSA). Special attention is paid to HSA, as it transports drug molecules and bound ligands. Changes that occur with DNA and HSA after exposure to EMF and cadmium ions are studied using the method of fluorescence spectroscopy. Material and Methods -Aqueous solutions of HSA and DNA were the objects of this study. They were extracted from whole blood samples obtained from volunteers. The samples were processed for 10 minutes with EMF intensity at 24±4 А/m and frequency increased stepwise by 2 Hz. Results -It was shown that after HSA and DNA were treated by EMF and cadmium ions, there was a significant increase in their fluorescence intensity when compared to control solutions, which reflects building of cadmium ions into DNA double helix as an intercalating agent and a disbalance in nucleic acid metabolism as well. When concentration of cadmium ions in aqueous HSA solution was as high as 10 2 maximum acceptable concentration there was a softening of protein globules of HSA molecules within their native structure without complete protein denaturation. Conclusion -A conclusion was made that combined exposure of studied factors on DNA and HSA molecules leads to a more significant change in structure of these biopolymers when compared to separate exposure of low-intensity EMF and cadmium ions.

“…The target of EMF can be water, cell plasma membrane and genome. Under the EMF irradiation, the structure of the soft clusters of water molecules was changed and activated, thereby enhancing the metabolic function of the organism and improving the function of the organism (Tekutskaya et al, 2015). The effect of EMF on ion migration is mediated by direct or indirect effects on cell membranes (Dihel et al, 1985).…”

Improving the relative abundance of bacteria and their activity is still the basis for the efficient operation of anammox process. Here, biomagnetic effect was used to promote anammox granules. Batch test results show that the application of an electromagnetic field (EMF) with a strength of 0.09 μT increased the nitrogen removal performance of anammox by 32.44% while higher strength EMF of 0.20 and 0.25 μT inhibited the activity of anammox bacteria. Long-term experiment indicated that the addition of EMF with a strength of 0.09 μT greatly improved nitrogen removal performance of the granular sludge, especially the total nitrogen removal performance increased by 15.3%. After 120 days of reactor operation, the nitrogen loading rate was increased to 6.4 kg N/m3/d, and the total nitrogen removal rate of the reactors with and without EMF addition reached 4.92 kg N/m3/d and 4.25 kg N/m3/d, respectively. Throughout the experiment, the removal rate of NH4+-N and NO2−-N of anammox reactor with 0.09 μT EMT addition was always higher than that without EMF addition. The high-throughput sequencing analysis showed that the proportion of Candidatus Brocadia in reactors with and without EMF addition were 21.3% and 15.8%, respectively. The application of EMF with an intensity of 0.09 μT increased the relative abundance of the main anammox bacteria. 70 kos were enriched under EMF conditions, including ko00780 (Biotin metabolism), ko00540 (Lipopolysaccharide biosynthesis), ko00590 (Arachidonic acid metabolism). 51 kos like ko03030 (DNA replication) decreased after EMF addition. This study demonstrates the feasibility of EMF to promote anammox and expands the application of EMF in wastewater treatment.

“…Lain halnya dengan medan listrik, medan magnet ELF sulit dilemahkan oleh bahan bangunan atau bahan lainnya. Medan magnet ELF dapat menembus dinding hampir tanpa gangguan (Jiao et al, 2019;Tekutskaya, Barishev, & Ilchenko, 2015). Hal ini menunjukkan bahwa sumber medan magnet ELF eksternal seperti saluran listrik dan sumber tegangan di sekitar manusia mungkin memiliki pengaruh yang signifikan terhadap sistem biologi.…”

Kekhawatiran masyarakat mengenai dampak negatif yang ditimbulkan dari paparan radiasi elektromagnetik ini masih terus diteliti hingga saat ini. Oleh karena itu, sangat perlu dilakukan suatu studi penelitian untuk mengukur dan memetakan tingkat radiasi elektromagnetik dengan tujuan menganalisis potensi risiko yang terjadi. Paparan radiasi elektromagnetik diukur menggunakan electromagnetic field tester, kemudian hasilnya dibandingkan dengan pedoman keselamatan yang dikeluarkan oleh ICNIRP dan WHO. Hasil yang diperoleh bahwa tingkat paparan radiasi yang diukur dalam satuan mikrotesla di 29 titik lokasi di Universitas PGRI Yogyakarta jauh di bawah pedoman ICNIRP untuk lingkungan pendidikan dan kerja. Nilai medan magnet terukur tertinggi adalah 132,46 µT, sedangkan nilai medan magnet terukur terendah adalah 1,436 µT. Medan magnet diatas 0,3 hingga 0,4 µT dapat meningkatkan risiko leukimia dalam jangka panjang. Penelitian ini telah menghasilkan informasi yang bermanfaat sebagai dasar pengambilan kebijakan kesehatan di lingkungan kampus Universitas PGRI Yogyakarta
