Global warming is one of the most severe effects of climate change, which is evidenced by its impact on the dynamics of tropical glaciers around the world (1). Peru possesses 70% of the world’s tropical mountainous ecosystems and Ancash is the region that houses the largest glacial area: the Cordillera Blanca (8). The Quillcay sub-basin is supplied by glaciers from this mountain range and comprises the Cojup, Quilcayhuanca and Shallap micro-basins, which are sources of water for the socioeconomic activities of neighboring population centers. However, in the Shallap and Quilcayhuanca micro-basins, the presence of highly toxic heavy metals such as arsenic (As), cadmium (Cd) and lead (Pb) has been detected, which is exclusively attributable to acid rock drainage (ARD) generated due to glacial retreat, since there is no mining activity in the area (9, 13, 20). Although the presence of these heavy metals from ARD has been reported in the Quillcay sub-basin, especially in the Shallap micro-basin (14, 15, 16, 17, 18), there are no studies that 5 indicate the potential effects of exposure to heavy metals in the health of the inhabitants of the communities that use the water bodies of the micro-basins affected by the DAR as a hydrological resource. For this reason, considering the use of the Shallap-Huapish-Toclla irrigation canal as a route of exposure to heavy metals, this project proposes to determine the potential effects on the health of the communities located in the Quillcay sub-basin that may be related to exposure to heavy metals (As, Cd, Pb) generated by acid rock drainage after glacial retreat. For this purpose, a longitudinal cohort study is proposed where families who refer to the use of Shallap-Huapish-Toclla irrigation canal will be recruited to confirm their participation in the project for two consecutive years, where biological and environmental samples will be extracted every 3 months. Biological samples will be obtained according to the heavy metal, mainly blood (Pb) and urine (As and Cd). In addition, a sociodemographic survey will be taken to identify possible risk factors and routes of exposure to heavy metals. The environmental samples correspond to the water from the Shallap River, the irrigation canal, the sources of drinking water and the analysis of the concentration of metals in the roots of the crops ingested by the families and in the soil where they grow.
