    Determination of the carbon footprint of animal waste and climate change; karaman example
    (Konya Teknik Univ, 2024) Argun, Yusuf Alparslan; Çakmakcı, Özgür
    Climate change is a major concern around the world. In this context, the carbon footprint of animal waste is of critical importance for sustainability and climate change management. The aim of this study is to estimate the carbon footprint resulting from animal breeding and animal waste in the Karaman region. In the study, 2022 data was used and there are 1019277 sheep and 81368 cattle for Karaman. In the study, Tier 1 and Tier 2 approaches were used to estimate methane gas emissions related to both enteric fermentation resulting from animal digestive processes and manure management. According to the results of the study, the results obtained using Tier 1 and Tier 2 approaches are as follows: 0.4924-0.5014 kg CO2e per 1 liter of milk for Cattle. For sheep, it is 4.5167-6.5627 kg CO2e per 1 kg of meat. For goat, it is 5.08136.0231 kg CO2e per 1 kg of meat. These results can be taken into account when creating strategies to reduce methane gas emissions. It is recommended to add better quality and high energy content foods to the feed ration, especially to reduce enteric fermentation. In addition, this study is a resource for relevant researchers working in the field in calculating the carbon loads of animal waste and is thought to be a guide for decision makers and practitioners.

    Examination of heavy metal concentrations and their interaction with anthropogenic sources in Ermenek Dam Lake (Turquoise Lake)
    (Springer, 2025) Argun, Yusuf Alparslan
    This study aims to determine the spatial distribution of heavy metal pollution in Ermenek Dam Lake, water quality assessment and pollution sources. For this purpose, samples were taken 6 times a year from 12 points determined in 2024. Physico-chemical parameters and heavy metals were analyzed in the study. Using the analysis results, indexes such as Water Quality Index and Heavy Metal Pollution Index were calculated. The results show that the lake water complies with TS 266 and WHO standards. The index results indicate that the lake water is at low pollution and risk level and is safe. The distribution and sources of heavy metals were examined using correlation analysis, Principal Component Analysis and Hierarchical Cluster Analysis. Correlation analyses showed that there were significant relationships between pH, temperature, conductivity, dissolved oxygen and TDS and heavy metals. PCA results revealed that Zn was positively correlated with temperature and pH, while Mn and Ni were inversely correlated. The alignment of Pb, Cu and Cd in the same direction showed that these parameters were affected by common sources. HCA results showed that Cr and Fe have similar transport and source properties, while Mn and Ni are affected by different sources. In general, it was determined that heavy metal pollution in lake water was at low levels and local concentrations were present. The study revealed the effects of anthropogenic activities on the lake ecosystem. The findings of the study provide a guiding basis for water quality management in similar hydrological systems.

    Mapping the dispersion pollution load of animal waste and ınvestigating its environmental effects: the case of karaman
    (2023) Argun, Yusuf Alparslan; Çakmakcı, Özgür
    Animal wastes are not stored correctly and are used haphazardly without control in agricultural lands. As a result, it causes many irreparable environmental pollution, especially water pollution. These wastes, which are described as diffuse pollution, cause pollution of both underground and surface water resources directly or indirectly and even make them unusable. In this research, waste generation as a result of animal breeding in Karaman province, its districts, neighborhoods and villages and the effects of animal wastes on environmental pollution were evaluated with distributed pollutant load calculations. In the study, the number of 1019277 ovine and 81368 bovine in Karaman in 2022 was used. The total nitrogen (TN) produced annually by the animals has been calculated as 1,723.23 tons/year, and the total phosphorus (TP) amount is determined as 124.23 tons/year. Additionally, for large ruminant animals, the annual total amount of dry manure is 130,305.77 tons, and for small ruminant animals, it is 41,984.27 tons. To prevent environmental pollution, these wastes should be stored in closed areas in compliance with standards, and processes such as composting, drying, and biogas production should be applied. By doing so, not only can environmental pollution be mitigated but also economic value can be obtained. The proper management and utilization of these wastes have high economic potential and can contribute to sustainable development, supporting the country’s economy. In addition, this study is a source for researchers working in the field in calculating the pollution load of animal wastes and is thought to be a guide for decision makers and practitioners.

    Waste characterization of karaman province and determination and comparison of individuals' waste approaches
    (2023) Argun, Yusuf Alparslan; Bilgin, Melayib
    The most basic building block of solid waste management is to determine the amount of waste generated by individuals in a day. As it can be understood from here, the most important issue in solid waste management is individuals. Therefore, all kinds of waste management studies should be based on the individual. In our study, a questionnaire was applied to 1 263 people residing in Karaman. In addition, according to income levels, 5 pilot regions were determined and characterization studies were carried out in different time periods. Of the wastes generated as a result of characterization, 45.08% of kitchen wastes, 3.41% of park and garden wastes and 30.36% of recyclable wastes. Only 18.6% of the recyclable waste potential is collected with the existing system. Within the framework of the survey, the rate of those who collect recyclable waste separately is 21%. In addition, it is understood from the survey study that individuals do not know what type of waste is produced in their homes. In this framework, waste collection and evaluation suggestions were presented by determining the waste potentials with the characterization study and the individual attitudes with the survey study.
