exhaust gas
The gaseous waste product produced during combustion in engines, heating systems, or industrial plants. Exhaust gases are often harmful to the environment and to health.
Alte Autos stoßen oft zu viele schädliche Abgase aus.
Old cars often emit too many harmful exhaust gases.
'Abgas' is composed of the prefix 'ab-' and the noun 'Gas' (gas). The prefix 'ab-' here expresses that something goes away or is a waste product. So it is literally a 'gas that goes away.'
Die Industrie muss ihre Abgase filtern.
Industry has to filter its exhaust gases.
Although the singular form 'das Abgas' exists, the word is almost always used in the plural, 'die Abgase' (exhaust gases). This is because combustion typically produces a mixture of different gases.
In vielen Städten ist die Belastung durch Abgase zu hoch.
In many cities, pollution from exhaust gases is too high.
Common verbs used in connection with exhaust gases are 'ausstoßen' (to emit), 'produzieren' (to produce), or 'reduzieren' (to reduce). Typical adjectives are 'schädlich' (harmful), 'giftig' (toxic), or 'sauber' (clean).
