The Geita Gold Mine (GGM) and North Mara Gold Mines (NMGM) have developed large quarries in the middle of fertile agricultural lands. Possible hazardous impact on the natural recourse has warranted a study on the trace element concentrations in soils, sediments, and natural waters. Generally, ...
Several critical migration routes and pathways of human exposure to PTEs in ASGM exist. Firstly, there is a common occurrence of incidental ingestion of soils, especially by young children and pregnant women that exhibit pica (Dooyema et al.2012b; Gottesfeld et al.2015; Moyo et al.2021; Nya...
