Effects of different irrigation practices using treated wastewater on tomato yields, quality, water productivity, and soil and fruit mineral contents
Wastewater use in agricultural irrigation is becoming a common practice in order to meet the rising water demands in arid and semi-arid regions. The study was conducted to determine the effects of the full (FI), deficit (DI), and partial root-zone drying (PRD) irrigation practices using treated municipal wastewater (TWW) and freshwater (FW) on tomato yield, water use, fruit quality, and soil and fruit heavy metal concentrations. The TWW significantly increased marketable yield compared to the FW, as well as decreased water consumption. Therefore, water use efficiency (WUE) in the TWW was significantly higher than in the FW. Although the DI and the PRD practices caused less yields, these practices significantly increased WUE values due to less irrigation water applied. The water-yield linear relationships were statistically significant. TWW significantly increased titratable acidity and vitamin C contents. Reduced irrigation provided significantly lower titratable acidity, vitamin C, and lycopene contents. TWW increased the surface soil and fruit mineral contents in response to FW. Greater increases were observed under FI, and mineral contents declined with reduction in irrigation water. Heavy metal accumulation in soils was within safe limits. However, Cd and Pb contents in fruits exceeded standard limits given by FAO/WHO. Higher metal pollution index values determined for fruits also indicated that TWW application, especially under FI, might cause health risks in long term
THE EFFECT OF DIFFERENT IRRIGATION APPLICATIONS ON THE BLOSSOM-END ROT IN TREATED WASTEWATER-IRRIGATED TOMATOES (LYCOPERSICON ESCULENTUM)
The study investigates the effect of water deficit conditions on blossom-end rot (BER) in tomato. Drip irrigation was used in irrigation. Therefore, experiment was conducted as a randomized complete block design (three replicates), in a 2 x 5 factorial arrangement, corresponding to two different water resources [treated wastewater (TWW) and freshwater (FW)] and five different irrigation practices. The irrigation strategies comprised full irrigation (100%), deficit irrigation, which involves the use of 75% and 50% of the water used in full irrigation, and partial root drying (PRD). According to the study results, in the full irrigation applications, blossom-end rot according to the fruit number values were 10.85% in fresh water irrigation while it was the lowest with 8.57% for treated wastewater. Also, in full irrigation applications, blossom-end rot values according to fruit weight were found to be lower compared to those in other applications. It was determined that there was a negative relation between blossom-end rot and Ca value. The lowest blossom-end rot incidence was observed in the full irrigation applications, while it was lower in the PRD applications than in the D applications. In the production of marketable tomato, the PRD applications can be more advantageous than the D applications under water shortage conditions
AN EVALUATION OF WATER QUALITY IN MICRO-CATCHMENTS WITH HIGH EROSION RISK WITH CCME WATER QUALITY INDEX: CASE OF CAPAKÇUR MICROCATCHMENT
A significant portion of the world's freshwater resources is allocated to agricultural irrigation. However, these waters are increasingly polluted due to various environmental factors. This pollution subsequently leads to soil contamination through irrigation and the degradation of specific productivity characteristics. As a result, monitoring water resources has become a critical global concern. In this study, we evaluated the water quality of the & Ccedil;apak & ccedil;ur Stream, an essential water source for the Bing & ouml;l Plain, using the Water Quality Index (WQI) developed by the Canadian Council of Ministers of the Environment (CCME). Monthly samples were collected from six different locations throughout 2019. Subsequently, 22 physicochemical parameters related to water quality were analyzed. The analysis indicated that the lowest water quality index values for the & Ccedil;apak & ccedil;ur Stream occurred in July in the monthly assessment and during the spring season. In contrast, the highest water quality index was recorded in January, both monthly and during summer. Notably, all obtained results were classified as marginal according to the WQI classification. The index values ranged from 50 to 54 according to the seasons, 49 to 56 according to the months, and 48 to 56 according to the sampling points. Consistent results (52) were observed during both dry and wet precipitation periods. These findings emphasize the urgent need for a cautious approach in using this water resource for irrigation, alongside the importance of regular monitoring and periodic analyses to maintain its quality

Public health challenges after the February 6 earthquakes: A comprehensive review of immediate and long-term impacts in Türkiye
Earthquakes are one of the most destructive natural hazards that cause loss of life, loss of property and destruction of infrastructure when they interact with vulnerabilities in human systems. The health impacts of these events are not only limited to immediate trauma and injuries, but also affect both physical and mental health in the short and long term. In this context, understanding the short- and long-term public health impacts of earthquakes and developing effective solutions is a priority both nationally and internationally. This review comprehensively examines the health challenges posed by earthquakes, focusing on the earthquakes that occurred in Türkiye on February 6, 2023. It addresses acute responses such as post-earthquake trauma management, emergency health services, potential earthquake-related risks and search and rescue activities, as well as chronic challenges such as sustained physical rehabilitation and psychosocial support in the long term. By analyzing current strategies and outcomes, this study aims to provide important insights into effective health management practices following earthquakes
