In the world, most of the underground and surface water supply sources are affected by the presence of manganese Mn2+, which is one of the biggest pollutants and causes an impact on the environment. Underground mining operations generate acidic water, whose pH is between 2 and 6; however, the mining companies do not present methodologies for control. Acid water samples were obtained from the industrial area of the Carahuacra mining production unit (Volcán S.A.A. Mining Company), according to the Water Monitoring Protocol of the National Water Authority (ANA) at 4600 meters above sea level, in the province of Yauli, Junín Region. The acidic water studied has a pH between 3.5 and 5.5 and a Mn2+ concentration of up to 250 mg/L. According to current regulations, the concentration is required to be reduced below 0.2 mg/L (ECA-2017). The objective of this work is proposing the use of sodium ...

The experience of waterbird censuses in Peru started at the beginning of Century XXth with this kind of censuses made by the Peruvian Guano Company and then by IMARPE. Between 1992 and 2016, annual censuses have been conducted in 61 wetlands on 12 Peruvian departments, a total of 151 residents and migratories birds were registered. Censuses have contributed greatly to improve species of waterbirds knowledge and synergies among institutions and ornithologist that through volunteerism collect important data to the conservation of species and wetland management with particular reference to the high Andean slopes. The taxonomic composition of the species, the importance of the inventories, the migration routes of birds from the Nearctic, Austral and high Andean regions, and the protected areas in the conservation of wetlands and biodiversity are analyzed. The aim of this paper is to make a h...
