The current standards used for nitrogen pollution evaluation are lacking, and scientific classification methods needed to improve water quality management capabilities. This study addresses the important issue of assessing surface by utilizing two advanced multivariate statistical techniques: self-organizing maps (SOMs) obtained using K-means algorithm Hasse diagram technique (HDT). research ta...

Abstract. Iron (Fe) in aerosol particles is a major external source of micronutrients for marine ecosystems and poses potential threat to human health. To understand the impacts Fe, it essential quantify sources dissolved Fe total Fe. In this study, we applied receptor modeling first time apportion fine collected under five different weather conditions Hangzhou megacity Eastern China, which upw...

Electricity demand in megacities may exert substantial stress on water resources, which is often expressed through the scarcity footprint for electricity consumption (WSFE). Conversely, constrain production, leading to increased vulnerability production. The WSFE and related of production reflect two aspects water-electricity conflict. This varies over time by both amount location However, no s...
