Heavy metal composition in the Plantago major L. from center of the Murmansk City, Kola Peninsula, Russia

Plantago major is an indicator of environmental pollution in the city. The plant grows along the traversed paths, close to the sidewalks. Contaminating substances accumulate on the leaves of the plantain. In the summer of 2016, samples of plants were collected in the central Murmansk region for analysis using a scanning electron microscope to identify dust particles on their surface, and to study leaves using the ICP-MS method to determination of heavy metals content. A relatively serious concentration of lead, zinc, copper, nickel as well as high arsenic and chromium content has been demonstrated in the city center, along with ties with human activities (vehicular traffic). High iron content is associated with peat soils used in the city for fertilization. The remaining metal content is relatively low. DOI: http://dx.doi.org/10.5281/zenodo.146106

Political challenges of Global Environmental Security: uranium legacy in Kyrgyzstan, obstacles, perspectives and regulatory infrastructure

학위논문 (석사)-- 서울대학교 대학원 : 국제대학원 국제학과(국제지역학전공), 2018. 8. 송지연.After 1991, since declaring and independence from the USSR, Kyrgyzstan and other Central Asian countries have encountered a wide pattern of concerns including environmental and security issues which were inherited with the fall of the Soviet Union and its vast nuclear infrastructure. One of them is abandoned uranium mines, unprotected uranium tailings, and wastes located in vicinity to populated areas. If an environmental emergency involving these tailings were to happen, particularly in transboundary areas, it can influence the health, economy, and environment of the whole region. Such well-known threats are widely consulted at numerous levels of government and by diverse groups of experts. The paper is aimed to analyze risks posed by the uranium legacy sites and radioactive sources in Kyrgyzstan since obtaining an independence 1991 from USSR as well as examining efforts undertaken by the country and international community to address these threats. The case studies show an integral example of security dangers and could help to address similar issues in other countries.

Nuclear Nonproliferation: U.S. and International Assistance Efforts to Control Sealed Radioactive Sources Need Strengthening

A letter report issued by the General Accounting Office with an abstract that begins "Sealed radioactive sources, radioactive material encapsulated in stainless steel or other metal, are used worldwide in medicine, industry, and research. These sealed sources pose a threat to national security because terrorists could use them to make "dirty bombs." GAO was asked to determine (1) the number of sealed sources worldwide and how many have been reported lost, stolen, or abandoned; (2) the controls, both legislative and regulatory, used by countries that possess sealed sources; and (3) the assistance provided by the Department of Energy (DOE) and other U.S. federal agencies to strengthen other countries' control over sealed sources and the extent to which these efforts are believed to be effectively implemented.

Effects of Irrigation Rate and Planting Density on Maize Yield and Water Use Efficiency in the Temperate Climate of Serbia

Scarce water resources severely limit maize (Zea mays L.) cultivation in the temperate regions of northern Serbia. A two-year field experiment was conducted to investigate the effects of irrigation and planting density on yield and water use efficiency in temperate climate under sprinkler irrigation. The experiment included five irrigation treatments (full irrigated treatment – FIT; 80% FIT, 60% FIT, 40% FIT, and rainfed) and three planting densities (PD1: 54,900 plants ha–1 ; PD2: 64,900 plants ha–1; PD3: 75,200 plants ha–1). There was increase in yield with the irrigation (1.05–80.00%) as compared to the rainfed crop. Results showed that decreasing irrigation rates resulted in a decrease in yield, crop water use efficiency (WUE), and irrigation water use efficiency (IWUE). Planting density had significant effects on yield, WUE, and IWUE which differed in both years. Increasing planting density gradually increased yield, WUE, and IWUE. For the pooled data, irrigation rate, planting density and their interaction was significant (P < 0.05). The highest two-year average yield, WUE, and IWUE were found for FIT-PD3 (14,612 kg ha–1), rainfed-PD2 (2.764 kg m–3), and 60% FITPD3 (2.356 kg m–3), respectively. The results revealed that irrigation is necessary for maize cultivation because rainfall is insufficient to meet the crop water needs. In addition, if water becomes a limiting factor, 80% FIT-PD3 with average yield loss of 15% would be the best agronomic practices for growing maize with a sprinkler irrigation system in a temperate climate of Serbia
