In the recent years, the pollution of the environment by heavy metals has become a crucial problem across the world. Heavy metals consist of a group of metals and metalloids which have atomic density greater than 4000 kg m-3. Heavy metals such as Nickel (Ni), Cobalt (Co), Copper (Cu), Zinc (Zn), Lead (Pb) are present in the biota. These metals are also known as trace elements which play a very important role in various metabolic processes of plants, animals and microorganisms. Heavy metals may gain entrance into the human body through consumption of contaminated drinking water or ingestion of soil or crops grown on contaminated land. Heavy metals such as lead, mercury, cadmium and copper are collective poisons, which causes environmental hazards and are reported to be exceptionally toxic. These metals are important sources of oxidative stress in the cell and play an important role in a etiology of diverse human pathologies such as carcinogenesis. Exposure to heavy metal toxicity leads to brain damage, mental retardation, cerebral palsy, lung cancer, gastrointestinal abnormalities, dermatitis and death of the unborn fetus. Many metals have been shown to directly modify and/or damage DNA by forming DNA adducts that induce chromosomal breaks. The unrestricted access to the dumpsite means that each day, scavengers search for raw materials, much of which eventually finds its way back to neighborhoods as animal feed and even human food. Stray chicken, pigs, goats, dogs and cats roam the dumpsite eating the toxic matter and becoming vectors of pests and parasites that are eventually transferred to the surrounding home and hence causing diseases to both animals and human beings.

Measurement Results

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.

The Public Sphere

Durch den digitalen Medienwandel ist der Begriff der Öffentlichkeit problematisch geworden. Die Debatte fokussiert sich zumeist auf die Frage, ob die sogenannte bürgerliche Öffentlichkeit durch das Internet im Niedergang begriffen ist oder eine Intensivierung und Pluralisierung erfährt. Rudolf Maresch zeichnet die berühmte Untersuchung der Kategorie durch Jürgen Habermas nach und zieht den von ihm konstatierten Strukturwandel der Öffentlichkeit in Zweifel. Dagegen verweist er auf die gouvernementalen und medialen Prozesse, die jede Form von Kommunikation immer schon gesteuert haben. Öffentlichkeit sei daher ein Epiphänomen nicht allein des Zeitungswesens, sondern der bereits vorgängig ergangenen postalischen Herstellung einer allgemeinen Adressierbarkeit von Subjekten. Heute sei Öffentlichkeit innerhalb der auf Novitäts- und Erregungskriterien abstellenden Massenmedien ein mit anderen Angeboten konkurrierendes Konzept. Mercedes Bunz konstatiert ebenfalls eine Ausweitung und Pluralisierung von Öffentlichkeit durch den digitalen Medienwandel, sieht aber die entscheidenden Fragen in der Konzeption und Verteilung von Evaluationswissen und Evaluationsmacht. Nicht mehr die sogenannten Menschen, sondern Algorithmen entscheiden über die Verbreitung und Bewertung von Nachrichten. Diese sind in der Öffentlichkeit – die sie allererst erzeugen – weitgehend verborgen. Einig sind sich die Autoren darin, dass es zu einer Pluralisierung von Öffentlichkeiten gekommen ist, während der Öffentlichkeitsbegriff von Habermas auf eine singuläre Öffentlichkeit abstellt. </br></br>Due to the transformation of digital media, the notion of “publicity” has become problematic. In most cases, the debate is focused on the question whether the internet causes a decline of so-called civic publicity or rather intensifies and pluralizes it. Rudolf Maresch outlines Jürgen Habermas's famous study of this category and challenges his claim concerning its “structural transformation,” referring to the governmental and medial processes which have always already controlled every form of communication. Publicity, he claims, is an epiphenomenon not only of print media, but of a general addressability of subjects, that has been produced previously by postal services. Today, he concludes, publicity is a concept that competes with other offers of mass media, which are all based on criteria of novelty and excitement. Mercedes Bunz also notes the expansion and pluralization of the public sphere due to the change of digital media, but sees the crucial issues in the design and distribution of knowledge and power by evaluation. So-called human beings no longer decide on the dissemination and evaluation of information, but algorithms, which are for the most part concealed from the public sphere that they produce in the first place. Both authors agree that a pluralization of public sphere(s) has taken place, while Habermas's notion of publicity refers to a single public sphere.

This article argues for more extensive attention by environmental historians to the role of agriculture and animals in twentieth-century industrialisation and globalisation. To contribute to this aim, this article focuses on the animal feed that enabled the rise of ‘factory farming’ and its ‘shadow places’, by analysing the history of fishmeal. The article links the story of feeding fish to pigs and chickens in one country in the global north (the Netherlands), to that of fishmeal producing countries in the global south (Peru, Chile and Angola in particular) from 1954 to 1975. Analysis of new source material about fishmeal consumption from this period shows that it saw a shift to fishmeal production in the global south rather than the global north, and a boom and bust in the global supply of fishmeal in general and its use in Dutch pigs and poultry farms in particular. Moreover, in different ways, the ocean, and production and consumption places of fishmeal functioned as shadow places of this commodity. The public health, ecological and social impacts of fishmeal – which were a consequence of its cheapness as a feed ingredient – were largely invisible on the other side of the world, until changes in the marine ecosystem of the Pacific Humboldt Current and the large fishmeal crisis of 1972–1973 suddenly changed this.

Vegetables growing in mining areas have become a serious food safety concern because of the high levels of heavy metals always associated with mining. In this study, water used for irrigation, soil, cabbage, green pepper and green beans grown in tin mine areas of Heipang District, Barkin-Ladi LGA of Plateau State were analyzed for lead, cadmium and zinc, using Atomic Absorption Spectrophotometer (AAS). The concentrations of the heavy metals in water, soil, vegetables were all in the order Pb, >> Cd > Zn. In the vegetables, the order was: Pb → cabbage > green beans > green pepper; Cd → green beans > cabbage > green pepper; Zn → cabbage > green pepper = green beans. The transfer factors for all the metals (heavy metal in plant / heavy metal in soil) ranged from 0.95 to 1.48. There were high levels of Pb and Cd in all the vegetables, which may be attributed to the metals in the water used for irrigation. Whilst the concentration of Zn in all the samples were lower than recommended limits, the levels of Pb and Cd in the water, soil and vegetables were higher than the WHO/FEPA standard recommended limits reported for vegetables. The Cd concentrations of the vegetables also exceeded the tolerance thresholds for animals and human beings and therefore consumption of vegetable from the area would endanger the health of the population.

The relevance of the article is determined by the fact that in Russia there is no effective mechanism of state support for the activities of non-profit organizations in the field of “green Finance”. The role of non-profit organizations is leveled, which can become a serious help in solving economic problems, in particular, the problems of recycling and processing of secondary raw materials, the placement of industrial waste and household garbage, and landscaping of large megacities. The main financial burden in the field of “green economy” falls on States and large enterprises. Meanwhile, we cannot ignore the important role of non-profit organizations that can not only draw attention to environmental problems to the public, but also offer their own measures to solve environmental problems. In this regard, it becomes relevant to consider the participation of non-profit organizations in the implementation of environmental projects by attracting “green Finance”.

The aim of this paper is to discuss the major technological changes related to the implementation of large-scale cogeneration and biofuel production in the sugar and alcohol industry. The reduction of the process steam consumption, implementation of new alternatives in driving mills, the widespread practice of high steam parameters use in cogeneration facilities, the insertion of new technologies for biofuels production (hydrolysis and gasification), the energy conversion of sugarcane trash and vinasse, animal feed production, process integration and implementation of the biorefinery concept are considered. Another new paradigm consists in the wide spreading of sustainability studies of products and processes using the Life Cycle Assessment (LCA) and the implementation of sustainability indexes. Every approach to this issue has as an objective to increase the economic efficiency and the possibilities of the sugarcane as a main source of two basic raw materials: fibres and sugar. The paper briefly presents the concepts, indicators, state-of-the-art and perspectives of each of the referred issues.

The Impact

This paper seeks to understand why there has been an increase in photographic images exposing military violence or displaying bodies killed by military forces and how they can freely circulate in the public without being censored or kept hidden. In other words, it aims to analyze this particular issue as a symptom of the emergence of new wars and a new regime of their visual representation. Within this framework, it attempts to relate two kinds of literature that are namely the history of war and war photography with the bridge of theoretical discussions on the real, its photographic representation, power, and violence.  Rather than systematic empirical analysis, the paper is based on a theoretical attempt which is reflected on some socio-political observations in the Middle East where there has been ongoing wars or new wars. The core discussion of the paper is supported by a brief analysis of some illustrative photographic images that are served through the social media under the circumstances of war for instance in Turkey between Turkish military troops and the Kurdish militants. The paper concludes that in line with the process of dissolution/transformation of the old nation-state formations and globalization, the mechanism and mode of power have also transformed to the extent that it resulted in the emergence of new wars. This is one dynamic that we need to recognize in relation to the above-mentioned question, the other is the impact of social media in not only delivering but also receiving war photographies. Today these changes have led the emergence of new machinery of power in which the old modern visual/photographic techniques of representing wars without human beings, torture, and violence through censorship began to be employed alongside medieval power techniques of a visual exhibition of tortures and violence.

The present seminar paper mainly highlight  the concept of  water pollution, causes of water pollution,  Its Effects, Elements of  pollutants, Methods  used to prevent the water pollution in environment  and the mandatory initiatives taken by the concerned authorities for prevention of  water pollution. Water   is essential for survival of all living organisms on the earth. Thus for human beings and plants to survive on land, water should be easily accessible. The term “Pollution” is generally refers to addition of any foreign body either living or non – living or deletion of anything that naturally exists. The basic Sources of Water pollution causes due to Culmination into lakes, rivers, ponds, seas, oceans etc. Domestic drainage and sanitary waste, Industrial drainage and sewage, Industrial waste from factories, Dumping of domestic garbage, Immersion of Idols made of plaster of Paris, Excess use of Insecticides , pesticides, fungicides, Chemical fertilizers, Soil erosion during heavy rains and floods, Natural disasters, tsunami etc. General pollutants  which are also caused for water pollution  which include Organic, Inorganic, and Biological entities, Insecticides, Pesticides, Disinfectants ,Detergents, Industrial solvents, Acids, Ammonia fertilizers, heavy metals, Harmful bacteria, Virus, Micro –Organisms and worms, Toxic chemicals. Agricultural lands become infertile and thereby production also drops, Spread of epidemic diseases like Cholera, Dysentery, Typhoid, Diarrhea, Hepatitis, Jaundice etc. The  basic responsibility of the Government, NGOs, National Pioneer scientific Research Institutions may conduct  research oriented programs on control of water pollution by create  awareness among the public through mass media and Environmental Education on recycling units,  and  water treatment plants must be established both at domestic levels and Industry levels, Every citizen must feel responsible to control water pollution. There have been many water pollution prevention acts that have been set up by the governments of the world. But these are not enough for permanent water pollution solutions. Each of us needs to take up the responsibility and do something at an everyday at individual level. Otherwise we can’t survive in a society forever in a future.

AbstractThe heavy metals, such as Cr(VI), Pb(II) and Cd(II), in aqueous solutions are toxic even at trace levels and have caused adverse health impacts on human beings. Hence the removal of these heavy metals from the aqueous environment is important to protect biodiversity, hydrosphere ecosystems, and human beings. In this study, magnetic Nickel-Ferrite Nanoparticles (NFNs) were synthesized by co-precipitation method and characterized using X-Ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Field Emission Scanning Electronic Microscopy (FE-SEM) techniques in order to confirm the crystalline structure, composition and morphology of the NFN’s, these were then used as adsorbent for the removal of Cr(VI), Pb(II) and Cd(II) from wastewater. The adsorption parameters under study were pH, dose and contact time. The values for optimum removal through batch-adsorption were investigated at different parameters (pH 3–7, dose: 10, 20, 30, 40 and 50 mg and contact time: 30, 60, 90, and 120 min). Removal efficiencies of Cr(VI), Pb(II) and Cd(II) were obtained 89%, 79% and 87% respectively under optimal conditions. It was found that the kinetics followed the pseudo second order model for the removal of heavy metals using Nickel ferrite nanoparticles.
