  • Exposure to sewage from on-site sanitation and child health: a spatial analysis of linkages and externalities in peri-urban Bolivia

    Exposure to fecal contamination is a leading cause of childhood infectious diseases in low- and middle-income countries. Low-quality sanitation infrastructure and inadequate maintenance can make on-site solutions prone to spillage, exposing children to sewage. This paper uses a unique dataset with independent verification of sewage in and around the parcels of more than 20,000 houses with ...

  • Monitoring the effectiveness of advanced sorption materials for removing selected metals from water

    There are a number of ways to remove heavy metals from water. Sorption on granular media based on iron oxides and hydroxides is currently the most used option. The experiment was carried out using sorption materials GEH, CFH 0818, CFH 12 and Bayoxide, which are primarily designed to remove arsenic from water. Four columns were prepared with an inner diameter of 4.4 cm for the purpose of the ...
