In the article we studied chemical elements in the hair of children as a form of environmental monitoring of metals in a given area, since one of the objective indicators of the ecological and hygienic well-being of a territory is the status of trace elements as the most sensitive part of the population, especially children. Many foreign scientific studies have shown that a hair sample is a good indicator of a negative technogenic impact on humans, and it is known that the unfavorable state of children characterizes the ecogeochemical features of the area, so we took into account the accumulation of trace elements in the hair. The study showed an increase in lead and cadmium and a decrease in zinc, copper and chromium.

Background. Concentration of trace elements in the hair allows to get an idea how they are taken by the organism over a long period of time and to study relative correlations with different genetic, dietary and environmental factors. Research aim was to identify changes in the macro- and microelement status for young athletes involved in different sports activities depending on the preparation period within one-year training cycle. Methods. A total of 78 young athletes aged 12–17 years, 32 of which were swimmers (group I), 17 – tennis players (group II) and 29 – Taekwondo athletes (group III) participated in the study. Biological material (hair samples), the volume of 0.1–0.15 g were taken for experimental studies in three periods of time: preparatory, competitive and transition period within a one-year training cycle. Hair samples were analyzed using the method of X-ray fluorescence (XRF) in order to detect multiple elements. For quantitative analysis, 8 chemical elements (sulfur, potassium, calcium, iron, copper, zinc, strontium and selenium) were determined in a single hair sample. Results and conclusion. A non-invasive method to determine mass fraction of the chemical elements (sulfur, potassium, calcium, iron, copper, zinc, lead, chlorine, bromine, strontium, selenium) in a hair sample is an informative method for assessing the physiological response of the body (young athletes) with physical activity at different stages of training. The statistical analysis of the obtained results revealed the dependence of the concentration of trace elements from a kind of sports activity and stage of preparation for young athletes.

The article presents the results of a study of the element status of residents of different ethnic groups (Koryak, even, mestizo) Magadan region. By atomic emission and mass spectral analizovs inductively coupled plasma quantity content of co, cu, Fe, Zn, si, al, cd, Pb, sn, Hg hair. there was a slight deviation of the content of some essential elements (copper, iron, zinc) in aboriginal and Mtis on average. it is suggested that this phenomenon is caused by adaptation to the conditions of the indigenous population of the north. these low levels of heavy metals - aluminum, cadmium, lead, tin, cobalt, mercury, indicates the relative well-being of the environment in terms of pollution with toxic elements. the higher silicon content in the hair of aboriginal and Mtis is consistent with the data that the Magadan region is silicic province. Variability of the most studied trace elements higher in the Mtis compared with the natives. High individual variability of chemical elements can be the result of an imbalance element in disadaptative organism to the environment, or a manifestation of the individual characteristics of the organism. the possible consequences of deficiency and excess of trace elements in the indigenous population of the north.

The distribution of dissolved chemical elements (major ions, nutrients, and trace elements) in the Yenisei River estuary and adjacent water area in 2009 and 2010 are presented. These results were compared to the data obtained during previous hydrochemical studies of this region. The transport of major cations (Na, K, Mg, Ca) and some trace elements (Rb, Cs, Sr, B, F, As, Mo, U) in the estuary follows conservative mixing. Alkalinity also belongs to conservative components, however this parameter exhibits substantial spatial heterogeneity caused by complex hydrological structure of the Yenisei Bay and adjoining part of the Kara Sea formed under the influence of several sources of desalination and salty waters inflow. Concentrations of Pmin, Si, and V in the desalinized waters of photic layer decrease seaward owing to uptake by phytoplankton. The losses of these elements reach 30–57, 30, and 9% of their supply by river runoff, respectively. The content of dissolved phosphates and vanadium in the intermediate and near-bottom layers of the Yenisei River estuary strongly increases with salinity due to regeneration of precipitated organic matter, whereas silica remineralization is much less pronounced. Barium is characterized by additional input of dissolved forms in the mixing zone in the quantity comparable to that carried out by river runoff. This may be caused by its desorption from river suspended matter due to ion exchange. The transport of dissolved Al and Mn in the estuarine zone is probably controlled by the coagulation and flocculation of organic and organomineral colloids, which is indicated by a decrease in the concentration of these elements at the beginning of the estuary (31 and 56%, respectively) followed by a stable concentration further seaward.

The Status

Waste is generated by various day to day human activities. Adopting improper waste handling and disposal methods can harm the well-being of public and environment. Waste management creates new opportunities for entrepreneurs in terms of social causes and it affects the economic structure and economic status of any country. One of the new approaches in waste management and income generation is Social entrepreneurship. But in Bharat i.e. India the young entrepreneurs have a dearth of consciousness towards social entrepreneurship. This paper discusses the status of solid waste management in India and Government initiatives for managing Solid Waste at Dharamshala. The main objectives of study are 1) to check awareness of people in managing solid waste at Dharamsala 2) and how to convert the plastic waste into theme based parks as skilled initiative for entrepreneurs at tourist spots in Himachal Pradesh. The paper thus explores the scope for entrepreneurs in waste management. The study reveals that Solid waste management concept attracted the attention of government around 1970s. But till now we believe in filling the waste in the ground or putting them in the dustbin. Government of India has created few acts and rules on waste management which are listed in this paper. Through this study it is revealed that people of Dharamshala welcome to the construction of themed parks made from plastic bottles. Majority of these people believe in separating waste at home and according to them conditions of waste disposal at Dharamshala are not very good. There is a positive correlation between people’s opinion of constructing theme parks and using plastic bottles in park’s construction. Study believes that the quantity of plastic waste in our country is endless which creates lot scope and opportunity to the social entrepreneurs.

Research Approach: This in-depth qualitative case study explores one school leader’s enactment of social justice leadership in an elementary school in Ciudad Juárez, Mexico. Analysis of interviews and observations revealed how this leader adapted her leadership to prioritize the severe needs of families and students in one of the world’s most violent cities. Findings: The article describes how the leader made sense of the community and its needs. Then, it examines how the leader enacted social justice leadership by addressing the out-of-school challenges that affected student achievement and well-being. Consequently, the leader’s focus shifted toward meaningful family engagement through adult education, community advocacy, and critical questioning of the status quo. Implications: Implications for future research, theory, and administrator preparation programs are presented at the conclusion of the article.

The Status

Both mainstream and disability bioethics sometimes contend that the self-assessment of disabled people about their own well-being is distorted by adaptive preferences that are only held because other, better options are unavailable. I will argue that both of the most common ways of understanding adaptive preferences—the autonomy-based account and the well-being account—would reject blanket claims that disabled people’s QOL self-assessment has been distorted, whether those claims come from mainstream bioethicists or from disability bioethicists. However, rejecting these generalizations for a more nuanced view still has dramatic implications for the status quo in both health policy and clinical ethics.
