    Society of Chemists and Chemical Engineers of Canton Sarajevo was founded in the year 2000 with an idea to promote chemistry in different sectors of our community. Its aim is to develop and improve the scientific, professional and educational activities in all areas of pure and applied chemistry. In Sarajevo, for the first time ever, Congress of Chemists and Chemical Engineers of Bosnia and Herzegovina with international participation will be held from 10th to 12th October, 2014. The conference is organized by the Society of chemists and technologists of the Sarajevo Canton and Faculty of Natural Science, Sarajevo. This conference will initiate and organize meetings of scientists doing research in different fields of chemistry and chemical technology, which will, I sincerely hope, result in a more intensive scientific cooperation, exchange of scientific knowledge and professional experience, and potential international scientific projects in perspective. 

    The scientific program will be of high quality with a great number of interesting topics and educational lectures with subjects as:
    - Analytical and Environmental Chemistry
    - Biochemistry and Biotechnology
    - Inorganic Chemistry
    - Biological Chemistry

    Air pollution has increased in recent decades in the industrialized world, resulting in a raise of allergic and other diseases that are becoming growing public health problem. Air pollution is a mixture of solid particles and gases in the air. Particle pollution, called particulate matter or PM, is a combination of fine solids and aerosols that are suspended in the air we breathe. Particles can come in almost any shape or size, and can be solid particles or liquid droplets. The particles are divided into two major groups. These groups differ in many ways. One of the differences is size, the bigger particles are called PM10 and the smaller particles PM2.5. The big particles are between 2.5 and 10 micrometers (from about 25 to 100 times thinner than a human hair). The small particles are smaller than 2.5 micrometers (100 times thinner than a human hair). Inhaling them can increase the chance to have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution. Particle size is an important determinant of the fraction of inhaled particles deposited in the various regions of the respiratory tract. Most aerosols present in natural and work environments are polydisperse. This means that the constituent particles within an aerosol have a range of sizes and are more appropriately described in terms of size distribution parameters. Size is not the only difference. Each type of particle is made of different material and comes from different places.

    Atmospheric particles are emitted from a wide variety of anthropogenic and natural sources, and consequently their physical and chemical properties may vary widely. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Susceptibility of an individual to adverse health effects of PM can vary depending on a variety of host factors such as age, physiological activity profile, genetic predisposition, or preexistent disease.

    Recent epidemiological studies have provided solid evidence for the association of airborne particulate matter (PM) concentrations with adverse respiratory health effects. Acute and chronic inhalation can result in damage to the lung including cancer, and chronic inhalation affects other organ systems. However, the mechanism is unknown. Thus, determining, identifying and tracking air pollution and its adverse effect on health, requries continuous focus in attempt to address and stop this serious problem of modern world.

    Subscribing to modern lifestyle, humans have directly and indirectly affected the environment in a positive and sometimes less positive way. A number of “so called modern age” diseases have a direct link to environmental changes. The World Health Organization estimates that about a quarter of the diseases facing mankind today occur due to prolonged exposure to environmental pollution. Apparently, there was a price to be paid for a commodity of a modern life. Inorganic and organic pollutants have found its way into a water streams, soli, and air disrupting complete eco systems, and affecting human health. At this time, the need for trained environmental chemist is not only necessary but urgently needed.

    The field of environmental chemistry is both very broad, but core knowledge stems from basic chemical principles containing all the aspects of organic chemistry, analytical chemistry, physical chemistry and inorganic chemistry. Additional topics dealing with a specific aspect of applied chemistry in environment ads to a broad and interdisciplinary nature of a subject.

    Environmental chemistry is a fairly a new science discipline that emerged only in the last decades of the 20th century. The benefits of having sound environmental chemistry program are immense and absolutely necessary in regards to a global environmental strategy outlined by international and regional organization. Thus, a new program at Faculty of Science, Department of Chemistry, focusing on monitoring and environmental protections with strong core knowledge in chemistry is exactly what is needed at this time. After all, we are morally obligated to consider the consequences of our acts and act upon it.

    This issue of the magazine is dedicated to the initiator of chemistry in Bosnia and Herzegovina, an academician Mladen Dezelic.

    Academician Dezelic was a pioneer in many ways: the establishment of the Department of Chemistry at Faculty of Philosophy, registrar of the Faculty of Science and Mathematics in Sarajevo, founder Society of Chemists and Technologists of Bosnia and Herzegovina, the first Editor-in-Chief of the Bulletin of the Chemists and Technologists of Bosnia and Herzegovina, one of the founders of the Academy of Sciences and Arts of Bosnia and Herzegovina, and much more.

    It all started back in 1949 at the invitation of the authorities of Bosnia and Herzegovina to come in Sarajevo and founded university chemistry classes. On his initiative and thanks to his efforts, the Institute of Chemistry and Physics in Sarajevo was designed and built, and after the establishment of the Faculty of Science and Mathematics, he became the head of the Department of Chemistry and director of the Chemical Institute.

    Mladen Dezelic can be said to be the father of chemical science in Bosnia and Herzegovina.

    In his scientific work, he dealt with organic synthesis and research of natural compounds. He researched the chemistry of pyrrole, porphyrin and hemin, studied nicotine and its derivatives, coumarin derivatives and their anticoagulant effect, and glycosidic compounds. Engaged in the problem of stabilization of vitamin C in solutions. He worked in the field of physical chemistry with thermochemistry, polarography and spectrophotometry. Work on the study of balance mixture of heavy water D2O and ordinary water H2O gave results that are still cited in manuals with tables of physical and chemical data on hard water.

    The bibliography of Dr. Mladen Dezelic scientific works includes a large number of scientific works in magazines and scientific anthologies, books, works from the history of science and culture, patents, professional and encyclopedic articles.

    "Academician Mladen Dezelic day" was recently organized at the Faculty of Science and Mathematics in Sarajevo, where his life and work were presented.

    Dear user,

    In front of you is the 38th issue of the magazine "Bulletin of the Chemists and Technologists of Bosnia and Herzegovina", published by the Faculty of Science and Mathematics in Sarajevo. If only we had luck, if God granted us a more civilized environment, this would be, at least, the 58th number, and this text would not even exist. Barbaric attempts from the hills to destroy all civilization achievements in our country resulted, unfortunately, in a serious setback in the development of chemistry, chemical technology and scientific fields and disciplines that rely on chemistry, as well as difficult compensable stoppage in scientific and professional journalistic activities throughout Bosnia and Herzegovina, and especially in Sarajevo. Regardless of all these difficulties, the scientific and professional curiosity of the local chemists as well as the necessary and present enthusiasm and need to develop and progress, were not absent. The results of scientific and professional research of our personnel were announced in such scientific journals in our immediate environment, but also far beyond it. With considering the capacities of today's chemists, especially their youth and good health training, it is no longer enough to perform and publish individually, even if it is within the framework of respectable world scientific institutions and reputable reference journals. This practice should be continued whenever it is useful for our environment and people, but must gradually focus on incorporating the acquired knowledge into our chemical reality.

    Today, this work must be approached from a systematic and systemic platform approach to science, and the results of this approach must be published in domestic, own, scientific and professional magazines. Despite the fact that the modern world has become "small" in many aspects, even in scientific informatics, the continuation of the appearance of this journal will give contribution to the world of science from Bosnian-Herzegovinian sources, primarily from Sarajevo, but also from other university and scientific research centers in Bosnia and Herzegovina.

    With the desire that this magazine becomes a respectable scientific and professional publication, which will affirm our environment, the Earth and people in chemistry and related branches of science and thus achieve the desired goals, we recommend you to intensify your scientific activities, and inform our and the world's scientific public about their results by publishing them in this journal.
