The data collection about the input and output of mercury for the year 2008, was carried out during the years 2014 and 2015. The data used for estimation are mainly obtained from the Costa Rican Government’s official publications. The research was developed in order to create a national inventory of mercury releases into all environmental sectors in order to aid mercury management in Costa Rica. Total input and output of mercury, distribution into different environmental sectors, major contributions by mercury sources (“steps” “categories” and “subcategories”) are discussed. The standard estimation of total mercury input is 7174.00 kg/year. The biggest mercury input are “waste treatment and recycling” (3086.00 kg Hg, 43.17%) and “general consumption of mercury in products, as metal mercury and as mercury containing substances” (3189.00 kg Hg, 44.62%). The total mercury released is 31,689.29 kg/year. The biggest emission of mercury corresponds to the source “waste treatment and recycling” (28,359.29 kg/year, 89.49%). The “air” is the main impacted environmental sector due the different mercury inputs. A total of 28,155.60 kg/year (88.55%) is released in this media. Only 1635.10 kg/year (5.16%) of the total mercury emissions is deposited in the environmental sector named “general waste”. The rest of the environmental sectors evaluated are impacted with less of 3.00% of the total mercury released.展开更多
