The researchers studied water quality in the Dnipro River basin from 2016-2021. They found that the amount of water in the river has decreased, leading to lower water intake and poorer water quality. Pollution levels in the water exceeded safe limits, with high levels of organic compounds and harmful substances like pesticides and heavy metals. Climate change and industrial activities are major factors affecting water quality. The study suggests the need for better water management strategies and stricter regulations on wastewater discharge to protect the river's resources.
