Medical wastes are wastes released during healthcare. The institutions with the highest medical waste generation are hospitals. However, medical wastes are generated at many points, such as health cabins, pharmacies and infirmary facilities that employ more than 50 workers. Although 75-90% of these wastes fall under the general waste category, the rest fall into hazardous waste. Medical wastes are beginning to form in large volumes today due to the developing technology, increasing welfare level and widespread health services. Especially, the increase in the use of disposable devices and consumables used to provide hygiene are the most important factors that increase the formation of medical waste. In addition to being infected, medical wastes contain hazardous chemicals, drugs, toxins, radioactive substances, etc. Medical wastes are in hazardous / risky waste group that threatens human and environmental health. The separation, temporary storage, transportation and disposal of medic...

Abstract The main objective of this study is to determine the effects of COVID-19 measures on air quality in Turkey. For this investigation, a daily mean of PM10, PM2.5, NO2, CO, O3, and SO2 air pollutant data, provided from the measurement stations run by the Ministry of Environment and Urbanisation and the Istanbul and Izmir Metropolitan Municipalities were used. The R program, an open-code statistics program, was used to generate associated distribution maps using the data obtained. Data for 29 metropolitan cities and the province of Zonguldak, where the pandemic measures were first implemented, were examined for air quality changes. In evaluating whether the COVID-19 measures have had an impact on the air quality of the 30 given cities, two time periods were selected: a period before the COVID-19 measures were implemented (between January 1 and March 15) and the period in which the measures were in force (between March 16 and April 15). In order to take the effects of seasonal conditions on air quality based on the 2020 post-epidemic data into account, the average data from 2018 and 2019 were also compared. This study finds that the restrictions imposed during the COVID-19 pandemic period in the 30 major cities, in which most of the Turkish population lives, significantly improved the air quality. Assuming that some of the measures taken during the pandemic period will become permanent over time (such as the increase in home working, the decrease in air travel thanks to online meetings, the widespread use of distance education, the change in consumption habits and a reduction of waste), the epidemic period is thought to represent a turning point in increasing global air quality.

In today's conditions, with the phenomenon of urbanization, natural habitats, which people and animals need, are disappearing at an increasing rate. As a result of the rapid consumption of natural habitats, many species and human life are adversely affected. Open public spaces which people can spend their leisure time and get away from urban life, albeit for a short-term, and reach recreation, remain inadequate in terms of quality and quantity. Zoos, one of the places where people spend time with animals, are planned and designed with the concept of insufficient space. However, in order to be efficient for people and animals, exhibit areas of animals should have a wide and unlimited effect. In this study, the concept of zoo and purposes, types and planning-design principles of zoos will be discussed. Subsequently, the concept of wildlife park (safari park) will be examined. In summary, the fact that safari parks are in fact typologies of zoos and how they differ in our country will be explained. © SGEM 2015

ABSTRACT Desire of earn and consume more contempt of people leads to aggravate their environment. As a result, the air, water and soil have been affected and continue to this effect. Extinction of various species creatures and colorful plants is most important problem of recent decades. As a result, the ecological balance is affected negatively. While it is important to take precautions in preventive medicine before illnesses, it is important to keep clean the environment instead of cleaning after environmental pollution. Because cleaning process after environmental pollution requires great cost than keeping clean. The important thing is to keep the environment clean and use it without polluting. It is obvious that world is giving a distress signal because of contemptible and selfish usage of environment. Climate change and meteorological disasters are being adversely affected by the waste of resources. For a beautiful future, must be avoided from waste and green areas must be increased. Only one tree may be conducive to rid our planet. In this study, it has focused on the feasibility and the benefits of the projects which include the replanting of our environment particularly the roads sides.

Uygun olmayan uretim teknikleri sonucunda toprak kalitesi bozulmakta, toprak organik maddesi azalmakta, toprak icerisinde su, hava ve bitki besin maddesi hareketi engellenmekte ve bitki gelisimi zarar gormektedir. Tarimsal alanlarda organik madde azalmasinin baslica nedeni oksidasyon sirasinda karbonun atmosfere salinmasindan kaynaklanmaktadir. Bu baglamda topraga kaybettigi karbonu, artima camuru ve zirai atiklarla elde edilecek olan karbon saglamaktadir.

Organic air pollutants represent many different pollutants, including persistent toxic organics and volatile organic compounds (VOC). The VOC group includes about 150 different compounds, the majority of which are considered harmful and toxic to human health. Considering all these features, the removal of VOC is of great importance. According to the Industrial Air Pollution Control Regulation, VOCs in flue gases are classified, and the limit value for the most dangerous group is specified as 20 mg/m3 according to the degree of damage. From past to present, many different removal technologies have been developed and continue to be developed. Removal of pollutants at low concentrations by conventional methods is more inadequate than those above certain concentrations. Photocatalytic oxidation (PCO) is one of the technologies used for VOC removal recently. It has been determined that many different organic pollutants can be removed with this method. Within the scope of this study, the removal of benzene and toluene pollutants, which are two important VOCs frequently encountered in flue gases, by the photocatalytic oxidation method has been studied under UVC irradiation. In this study, a new photocatalyst by doping silver (Ag), a noble metal, and nickel (Ni), one of the transition metals, on TiO2 nanoparticles was developed and a laboratory-scale reactor system was designed. Many experiments were carried out by changing the system parameters such as ambient temperature (120 °C, 150 °C, 180 °C), humidity (25% and 50%), and percentage of Ag and Ni doping on TiO2 (0.5%, 1%, 2.5%, %5) and the most successful conditions for the removal of benzene and toluene contaminants were tried to be determined based on the results obtained. When all experiments carried out within the scope of this study were considered, the average removal efficiency for benzene was found as 89.33%, while the average removal efficiency for toluene was 88.23%. According to the obtained results, the most suitable conditions for the simultaneous removal of benzene and toluene pollutants with photocatalytic oxidation method under UVC light were determined as 120 °C temperature, 25% humidity, and 0.5% doping photocatalyst.

Water is the main source of life for all living creatures and water resources should be protected from draining away. There are two main sources of water that is used for water supply such as ground water and surface water. Both of them are fed by precipitation water in order to stay stable for providing consumption requirements. Thus, only one drop of precipitation water should not be wasted so storm water management practices come to light. Two of the mostly known storm water management practices are low impact development (LID) which works with nature to manage stormwater at place closer to its source and green infrastructure which uses natural processes to provide infiltration and evapotranspiration or reuses runoff on the generation area. There are many LID practices that have been used to adhere to these principles such as bio retention facilities, rain gardens, vegetated rooftops, rain barrels and permeable pavements. Green infrastructure can be used in wide range of landscap...

Hydrological cycle and water resources were affected by climatic change. Climate change mainly driven by human activity is affecting back to human being in various aspects. Especially water, a necessity of all creatures on the earth, is closely related with the climate change, and a number of research projects have complied the knowledge of global hydrological cycles and world water resources over past, present, and future. In order to see this effect, a semi-distributed monthly water balance model was proposed and developed to simulate and predict the hydrological processes. GIS techniques were used as a tool to analyze topography, river networks, land-use, human activities, vegetation and soil characteristics. The model parameters were linked to these basin characteristics by regression and optimization methods. The model development will also be used to obtain an appreciation of the process controls of water balance in large heterogeneous catchments in semi-arid climates. Results...

Konya Closed Basin is one of the largest basins in Turkey that takes minimum precipitation in the country. The current direction of underground water and surface waters of the basin is towards Salt Lake. Treated and untreated domestic and industrial wastewater from the city, solid waste leachate and surface water are going to Salt Lake via Konya Main Discharge Canal. The underground water level has been dropped as a result of climate change, drought, and excessive withdrawal of groundwater in recent years. This decline has caused a rapid degradation of the quality of groundwater, which in turn has deteriorated the irrigated soil by this water. Moreover, the annual drought index is at the most critical level in this arid and semi-arid region, which is seriously threatened by desertification due to an increase in temperature and evaporation resulting from climate change. Groundwater pollution is generally caused by domestic and industrial wastes and agricultural activities. Cleaning p...

Air pollution levels shows the interaction between the particles like dust, gas, smoke, water vapor, odor and many chemicals that presence in the amount of damage to living organisms and damage the materials. Various types of air pollutants in the atmosphere forms naturally or by human source activities the appearance of the air depends on the state of pollution. Particulate matter is one of these pollutants which has a significant effect on human health. It has the ability to stay in the air for a long period or even weeks, and because of its small size and lightweight, it can move to around very long distances. This study was carried out in the city center of Konya considering shopping centers as a measuring points to monitor the relationship between concentrations of PM2.5 and the change of climatic factors for different seasons. We took different points and at different location to measure PM pollution indoors. The highest values for summer season were obtained at location AB (1...

Flue gases are emissions that contain various pollutants in different concentrations and give rise to many health problems and environmental problems in the environment. Biological methods used in flue gas treatment; more economical, more efficient and environmentally friendly than physical and / or chemical methods. Biological methods can be applied within a filter or after contamination in liquid. The types of bacteria used in these methods are the main factors affecting the flue gas temperature, pH, and moisture treatment yield. A good control mechanism is needed under supervision as there are many factors that affect efficiency. In this study, different methods and factors affecting the treatment efficiency of ammonia in flue gas were investigated.

Desert dust rising from the African region and covered very long distances with meteorological events can be an important source of pollution for many countries from time to time. Although dust and sand masses that remain in the atmosphere for a long time are known to be inert and stable, but studies show that they affect vegetative production by changes in precipitation and radiation regimes. It is important for natural phenomena and has also revealed their effects in regions over which the atmospheric transport occurs. The Sahara dust storm of mid-May 2020 has strongly, affected many European countries. The Sahara dust and hot air transport is reported over the Mediterranean region to the Balkans and further to Turkey. Depending on the climatic conditions, the Sahara dust may remain in some regions for longer period. Rainy and humid weather conditions slow down the flow of dust and increase the settling rate in that region. In such cases it creates mud-like precipitation accompany...

In this study we activated pine barks (Pinus nigra) by using NaOH and this activated material used for the removal of Pb(II) ions from aqueous solutions. Chemical activation and its enhancement effect of adsorption capacity for treatment process have been investigated in this article. FT-IR analyses were examined for the determination of surface properties changes after activation. Maximum adsorption capacity was 49 mg/g at pH 8 and with a 180-min contact time (for 35 mg/L initial concentration and a 2.5 g/L solid-to-liquid ratio) These modification processes also decreased soluble organic compounds from pine barks leading to increase in chemical oxygen demand of water. Adsorption capacities of adsorbents increased quietly as a result of modification according increase of adsorbent surface activity.

Low concentration of chlorinated aliphatic compounds may be found in the wastewater, and has been accepted as toxic compounds for biological life. These volatile organic compounds (VOC) could be removed by different methods, but in this study, anaerobic decomposition was studied removal of VOC from the contaminated water. Aim of this work was treatment of VOC's by up-flow anaerobic blanket reactor (UASB) and to determine effects of different co-substrates (methanol and ethylene glycol) on VOC's removal at the anaerobic conditions. Furthermore, theoretical and practical investigation on the degradation of chlorinated hydrocarbons has importance in the water pollution. According to our results methanol was better co-substrate for VOC removal at anaerobic condition than ethylene glycol. Removal rates of DCM, CF, PCE and TCE in this investigation were approximately 65, 95, 100 and 90 % respectively with using co-substrate methanol.

Intended for human consumption water resources are rapidly decreased due to overuse, global warming and also polluting by pollutants. Metal concentrations are generally removed by precipitation, adsorption, biosorption and some chemical reactions in the receiving water media. Therefore, polluted waters by metals are caused to rarely toxic effects in living things in high concentrations. Metal polluted waters are generally caused to esthetic and cosmetic effects. Adsorption is one of the commonly used methods for metal removal. In recent years, researches about natural low cost adsorbents are increased. Factors such as modification and electricity costs increase the cost of adsorbent. In this study, dry acorn caps of Quercus robur were used as non-modify natural adsorbent. The batch experiments were carried out to removal of copper in water that has initial low concentration by prepared natural adsorbent.
