If you are removing silver and noticing odours you have to rethink your process.
Odours arise from you being exposed to chemical vapours. In an industrial or hobbyist setting this is bad.
You may have to install a fume hood to suck the gases away. But (always a but) you have to make sure the exhaust froom the unit doesn't impinge on anyone else. Local laws may give direction on this. Do not suck fumes into your furnace cold air return - everyone on the hot air distribution can be impacted.
For a small experimental station a contained fume hood with an activated carbon or chemical filter may be useful.
Check with local platers or silver recovery firms as to the potential problems and solutions. Local environmental agencies (EPA or equivalent in your jurisdiction) can also give guidance.
Aside: Getting loaded up on nitric acid fumes or silver is not good for your health. The nitric acid fumes can cause severe lung damage, the silver can turn you a nice shade of grey and impair your health.

Why is it hard to clean up water pollution?
The biggest problem in cleaning up water pollution is that first, you have to identify what the pollutant(s) is/are. There are many different techniques available for removing the various types of water pollutants. Physical filtration can remove solid, insoluble material and some microorganisms such as bacteria. Biological filtration is used to break down many organic pollutants into simpler, less toxic chemicals. Adsorbent materials such as activated charcoal can be used to remove a wide range of organic pollutants. Absorbent materials such as mineral clays can be used to remove various pollutants, particularly oils. Synthetic materials called ion-exchange resins can be used to remove chemicals such as nitrates and phosphates. The complete list of techniques and materials used to clean up water pollution would fill up an entire book.
