چکیده

Despite management of point sources, heavy metals today remain at an elevated level in the urban environment, with diffuse sources dominating the emissions. In order to manage these pollutants, it is necessary to understand the coupling between the urban sources of heavy metals and their monitored, environmental levels, for example in aquatic sediments. In this work, we suggest a simple approach to quantitatively model Cu from its urban sources through a complex aquatic system. We apply the proposed model to Stockholm, situated between Lake Mälaren and the archipelago of the Baltic sea, and discuss data availability along with conceptual difficulties. Using literature data, we show that Cu occurs at elevated levels in the aquatic sediment close to the centre of Stockholm, Sweden.

Health System Resilience: What Are We Talking About? A Scoping Review Mapping Characteristics and Keywords

Background Health systems are based on 6 functions that need to work together at all times to effectively deliver safe and quality health services. These functions are vulnerable to shocks and changes; if a health system is unable to withstand the pressure from a shock, it may cease to function or collapse. The concept of resilience has been introduced with the goal of strengthening healt...
