Sources and sinks of atmospheric carbon dioxide, methane and nitrous oxide are estimated for the tropospheric box over Hungary. It is found that the total (biogenic and anthropogenic)
strength of CO2-C emission is around 100 TgCyr-1.
16-20 % of this quantity is due to fossil fuel burning. This results in an annual anthropogenic emission of slightly less than 2 t per capita. The vegetation removes annually from the air over the country
about half of the mass emitted, while a small part of carbon dioxide molecules goes to the stratosphere by diffusion. This means that our region is a net carbon source, even if combustion effects are neglected. The total methane release of the country lies around 500 GgCyr-1 with the predominance of anthropogenic sources like solid waste treatment, natural gas production and distribution as well as
animal husbandry. Taking into account appropriate numerical values, a chemical removal of 233 GgCyr-1 can be calculated for the tropospheric air above the country. The sum of the magnitudes of
the methane diffusion into the stratosphere and dry deposition is less nearly by an order of magnitude than the mass removed chemically. The comparison of sources and sinks indicates that the tropospheric
box over the country is also a net source of carbon in reduced form. The emission of nitrous oxide (14 GgNyr-1 for 1992) is controlled by the use of fertilizers, while a smaller amount is liberated during combustion. The quantity emitted is practically balanced by the stratospheric loss.
