Plastic in global rivers: are floods making it worse?

چکیده

Abstract Riverine plastic pollution is of global concern due to its negative impact on ecosystem health and human livelihood. Recent studies show a strong link between river discharge transport, but the role floods still unresolved. We combined high-resolution mismanaged waste data flood extents with increasing return periods estimate flood-driven mobilisation, from local scale. that 10 year period already tenfold mobilisation potential compared non-flood conditions. In worst affected regions, increases up five orders magnitude. Our results suggest high inter-annual variability in previously ignored by transport models. Flood defences reduce substantially, regions vulnerable flooding often coincide during floods. Consequentially, clean-up mitigation measures risk management are inherently interdependent need be managed holistically.

Here we show that winter flood events in the UK are connected to Atmospheric Rivers (ARs), narrow ribbons along which a large flux of moisture is transported from the subtropics to the mid-latitudes. Combining river flow records with rainfall measurement...

Tuberculosis: are we making it incurable?

Tuberculosis (TB) is most probably the disease that has caused more damage to the human species throughout its history in terms of number of patients and, above all, death toll. There have been thousands of years spent fighting against Mycobacterium tuberculosis in which the human species could only rely on the efficiency of the immune system [1]. We must recall its importance as, in the pre-an...
