Yasin İlhanlı | Erman Ulker
Considering the importance of water in the world, the amount of usable water is not sufficient throughout the world, the existing available fresh water resources are not enough, therefore, water shortages may be encountered in the following years. Keeping the quality of water as it is demanded gains more importance than before. Particularly, heavy metals begin to interfere with groundwater resources, and the quantity of pollution growing due to industrialization, and urbanization. In the present study, the quantitative analysis of heavy metals in harvested rainwater from the rooftop of public buildings in Bornova, Izmir is investigated. The results show that a minimum of 5 μg of copper, 4 μg of zinc, 2.69 μg of lead, 0.095 μg of cadmium, 0.55 μg of chromium, 89,7 μg of iron, 0.96 μg of arsenic, 0.0119 μg of mercury and 3.88 μg of nickel should be tossed away for obtaining a liter of potable water. In conclusion, first flush diverters are recommended to convert these non-point pollutants to point source. Thus, municipalities can take necessary measures to protect the environment such as using phytoremediation and hyperaccumulator plants in sewages.

2022
Gülen Yıldız Turp | Tuğçe Avcı
Nowadays, consumer demand for healthy and natural food is reflected in the meat industry and researches and investments on this issue have gained speed. Nitrite is a widely used synthetic additive in meat products due to its contribution to the development of characteristic color and flavor, controls lipid oxidation and has an antimicrobial effect on pathogenic microorganisms, especially Clostridium botulinum. However, the fact that nitrite causes the formation of toxic, mutagenic and carcinogenic N-nitrosamine compounds and constitutes a risk to human health has led to the searches for alternative additives. An important part of the studies on this subject consists of testing the use of natural additives as an alternative to nitrite. In recent years, instead of using nitrate and nitrite in meat products, studies have been carried out to use organic acids and microbial resources. In addition to these methods, up-to-date technology applications such as high pressure, irradiation, encapsulation, active packaging containing nitrite, zinc protoporphyrin IX compound formation and cold plasma technology constitute other research areas that we encounter in reducing the nitrite rate in meat products. Within the scope of this review, the functions of nitrite in cured meat products, current potential methods for reducing nitrite content and the limitations of transferring these methods to industry were examined.

Roasting is the most important coffee processing stage that affects coffee flavour. Coffee brew is prepared by various methods and Turkish coffee brewing technique is one of the oldest methods among other coffee preparation techniques. In this study, volatile compounds of light, medium, dark roasted ground coffee and Turkish coffee brews prepared from light, medium, dark roasted coffees were evaluated and the effect of roasting process was determined. The volatile compounds from acid (2), alcohol (1), aldehyde (2), furan (8), furanone (3), ketone (1), lactone (1), phenol (3), pyrazine (19), pyridine (1), pyrrole (6), and thiophene (1) chemical group was detected in all roasted ground coffee samples. However, volatiles compounds from acid, alcohol and furanone group were not detected in any Turkish coffee brew. Pyrazines were main volatile compounds of light roasted ground coffee and Turkish coffee brew of light roasted coffee. On the other hand, furans were main volatile compounds of medium, dark roasted ground coffee and Turkish coffee brew prepared from medium, dark roasted coffees followed by pyrazines.

Güngör Karakaş
Global climate change, the effect of which has been increasingly felt in the last ten years, has made itself felt more in many regions in Turkey, especially in 2020 and 2021, and a serious temperature increase, floods and forest fires have been seen. Climate change affects the most vulnerable agricultural production. Since the adaptation of farmers to climate change is important in terms of food prices and sustainability of agricultural production, it is important to identify the barriers to adaptation of farmers to climate change. The aim of this research is to investigate the barriers to the adaptation to climate change of wheat producing farmers in Çorum province, where wheat is produced on 37% of the total agricultural land. In order to achieve this aim, 424 farmers were interviewed and their climate change 'understanding', 'perceptions', 'attitudes' and climate change adaptation 'barriers' were examined. As a result of the research, it has been determined that the farmers perceive climate change as "drying of water resources" and “increase in drought”, and they have an attitude that "we should strive together to adapt to the changing climate" rather than an individual struggle. In addition to these, it has been determined that “climate change is perceived as a serious problem” by the farmers and as a result of all these, the lack of “access to water resources” is the most important obstacle in adapting to climate change. In order to accelerate the adaptation of farmers to climate change, to protect them against the negative effects of climate change and to make local adaptation strategic plans, politicians, non-governmental organizations, public, private sector, universities, national and international organizations have important duties.

2022
Özlem Boran | Uğur Serbester
Hayvancılık sektörü, antropojenik sera gazı emisyonlarına katkıda bulunarak iklim değişikliğinde önemli bir rol oynamaktadır. Özellikle ruminant hayvanlarının üretim sistemlerinde sera gazı salınımının azaltılmasına yönelik çalışmalar küresel çapta büyük ilgi görmektedir. Metan gazı selüloz, hemiselüloz, pektin ve nişasta gibi hidrolize olmuş karbonhidratların rumende mikrobiyal fermantasyona uğraması sonucunda oluşmaktadır. Ruminantlar küresel sera gazı emisyonlarının yaklaşık %16’sına, küresel antropojenik metan emisyonlarının da %33’üne katkıda bulunmaktadır. Atmosferdeki metanın yarılanma ömrünün 12,4 yıl olduğu tahmin edilmekte olup radyoaktif etkisi ve küresel ısınma potansiyeli dikkate alındığında bu süre önemlidir. Dünya nüfusunun artması ile birlikte beslenmek için hayvansal ürünlere olan talep yükselecek ve daha fazla hayvansal üretime gereksinim duyulacak, bunun sonucunda metan emisyonuda yükselecektir. Hayvansal üretimi düşürmeden metan emisyonunun azaltılması önem kazanmaktadır. Bu derlemede, ruminant hayvanlardan kaynaklı metan salınımı, azaltma yolları ve ölçüm yöntemleri incelenmiştir.

Difficulties in adventitious root formation in blackberry (Rubus fructicosus L.) cuttings create a disadvantage for producers. The aim of this study is to investigate the effect of different growth regulator applications on the rooting ability of blackberry hardwood cuttings in order to avoid this problem. The experiment was carried out in the polycarbonate greenhouse of Tokat Gaziosmanpaşa University Agricultural Research and Application Center In the experiment, in addition to the control (pure water) group, Indole-3-Butyric Acid (3000 ppm IBA) and different doses of paclobultrazole (500 ppm PBZ1, 1000 ppm PBZ2, 1500 ppm PBZ3) were applied to hardwood cuttings separately and in combination. After the application, the cuttings were planted in perlite medium and left to root for 90 days. At the end of this period, in the cuttings removed; rooting rate, callus formation rate, root number, root length and root diameter parameters were examined. As a result of the study, the highest rooting rate was obtained from the IBA applied cuttings (%42.22), followed by the PBZ1 applied cuttings closest (%33.33). In addition, it was determined that PBZ applications had positive effects on root diameter compared to the control group. The results obtained are important in terms of contributing to the literature and benefiting the enterprises

Serpil Yilmaz | Esra Erikçi Bilgin
Although land-based pollution is expressed as the most important pollution factor in the pollution of the seas (80%), the rate of pollution originating from ships (approximately 20%) is not to be underestimated. The fact that marine pollution is caused almost exclusively by ships requires investigation of the measures to be taken against marine pollution from ships and their applicability. As a matter of fact, the most important cause of pollution caused by ships is ballast water, and it has been determined that over 7,000 marine organisms are transported between ports with ballast waters on a global scale every day. Ballast water is used to maintain the balance of the ship on the water when the ships are not loaded. Considering that 90% of international trade is still provided by ships and 3-5 billion tons of ballast water is transported by approximately 85,000 ships every year with world maritime trade, the importance of pollution caused by ballast water becomes apparent. While ballast water is one of the elements that cause the transport of exotic marine and freshwater organisms between all seas of the world and cause pollution, the pollution in question is very effective especially in the aquaculture sector. Therefore, in this article, the connection of ballast water with fisheries management has been examined and solutions have been sought for the problems.
