Whereas recent scientific studies have confirmed that some depletion of the ozone layer has already occurred and that the changes observed may be due, wholly or in part, to the increased presence in the atmosphere of trace gases, particularly chlorofluorocarbons (CFCs)

Considerando que estudos científicos recentes confirmaram que já se registou uma certa redução da camada de ozono e que as alterações observadas podem dever-se, total ou parcialmente, à presença crescente, na atmosfera, de gases residuais, nomeadamente clorofluorocarbonos;

The zero-CO2 power station is a long-term vision. Preventive climate protection demands the timely development of processes for the technically and economically rational separation of environmentally relevant trace gases from power-station emissions with a view to preventing the release of CO2 into the atmosphere.
A aposta em centrais eléctricas com «emissão zero» de CO2 é uma visão a longo prazo. A protecção preventiva do clima exige o desenvolvimento atempado de processos que permitam uma separação racional em termos técnicos e económicos dos gases residuais nocivos para o ambiente resultantes das emissões das centrais eléctricas, no intuito de impedir a libertação de CO2 na atmosfera.

gases traço


Explanation:
A expressão "traço" tem definição precisa em quimica analítica - trata-se de quantidades tão infimas que não são quantificáveis pelos meios de análise disponíveis, mas cuja presença foi detectada qualitativamente.

agree  Oliver Simões: De fato, existem várias referências aos gases traços na internet, inclusive este artigo na Wikipedia que define precisamente o que são: https://pt.wikipedia.org/wiki/Atmosfera_terrestre
5 mins
  -> Thanks Simões

agree  Matheus Chaud
2 hrs
  -> thanks Matheus

agree  Mario Freitas: Pensando em regras gramaticais, deveria ser "gases-traço" com hífen. Rsrs, se nem os professores se lembram do hífen, quanto mais os engenheiros, Mauro. Dont worry!
2 hrs
  -> Thanks Mario. Na verdade o 'traço' tem que ser singular, mas não me lembro de ter visto o hifen em textos de análise de gases. LATER - pois é, Mario o assassinato do hiffen por nossos literatos, foi mais um caso, felizmente, de lei "que não pegou"
