AI Article Synopsis
- The Black Sea region's population decline may impact river pollution, but a clear understanding of the relationship between population change, economic growth, and urbanization is essential.
- Future projections indicate that more than half of the rivers will see increased pollution levels compared to 2010, particularly in scenarios with poor wastewater management.
- Implementing advanced wastewater treatment could significantly reduce pollution by 68-98% by 2100, emphasizing the need for coordinated international efforts to achieve sustainability.
Article Abstract
The population in the Black Sea region is expected to decline in the future. However, a better understanding of how river pollution is affected by declining trends in population and increasing trends in economic developments and urbanization is needed. This study aims to quantify future trends in point-source emissions of nutrients, microplastics, Cryptosporidium, and triclosan to 107 rivers draining into the Black Sea. We apply a multi-pollutant model for 2010, 2050, and 2100. In the future, over half of the rivers will be more polluted than in 2010. The population in 74 sub-basins may drop by over 25% in our economic scenario with poor wastewater treatment. Over two-thirds of the people will live in cities and the economy may grow 9-fold in the region. Advanced wastewater treatment could minimize trade-offs between economy and pollution: our Sustainability scenario projects a 68-98% decline in point-source pollution by 2100. Making this future reality will require coordinated international efforts.

Background/aim: The epidemiological data on heart failure (HF) vary between regions within the same country. We aimed to investigate the epidemiological data on HF in Türkiye across all age groups regarding seven geographical regions.
Materials And Methods: We included all patients from the Turkish population who received a first diagnosis of HF between January 1, 2016 and December 31, 2022, using ICD-10 codes from the National Electronic Healthcare Database.

In the present study, the effects of coenzyme Q10 (CoQ10), which is widely used in daily life, on the methotrexate (MTX)-induced hepatotoxicity, which is widely used today in malignancies and autoimmune diseases, were examined. Twenty-four female Wistar albino rats were divided into four groups. The group 1 ( = 6) was given 1 mL corn oil by oral gavage (p.

As the intersection of river, sea, and land, river deltas are hotspots for the accumulation of microplastics (MPs). This study investigated the abundance and characteristics of MPs in surface sediments from shoreline area of the Yellow River Delta in northern China, elucidated their sources, and assessed their risk. The MPs isolated from sediment samples were detected and characterized using optical microscopy and micro-Fourier transform infrared spectroscopy (μ-FTIR).

Anthropogenic and climate factors are increasingly affecting the composition and functions of many marine biogenic reefs globally, leading to a decline in associated biodiversity and ecosystem services. Once dominant ecological component, modern oyster reefs in the Mediterranean and Black Sea and the Atlantic Ocean have already been profoundly altered by overharvesting, habitat loss and the introduction of alien species. Far less known are deep-water oyster reefs, which can however form substantial biogenic structures below 30 m depth.

Wastewater treatment plants (WWTPs) are one of the major collection points of microplastics (MPs). The MPs in influents and effluents of WWTPs were assessed for three cities on the southern coast of the Caspian Sea in the winter and spring seasons. The MP removal rate of WWTPs ranged between 71.
