Odor - Legislative Provisions

Legislative Provisions

While developing environmental legislation in Germany, it was noted that there was a need for a method to accurately measure odor. Since that time, the following laws have been established:

  1. "refinery guideline" (early 1970s)
  2. federal emission protection law (1974)
  3. technical guideline to keep the air fresh
  4. olfactory emission guideline (early 1980s until 1998)

Barriers around the sources of the odors have turned out to be badly feasible. Ramparts, plantings etc. are little effective, whereas plantations are, after all, often at least perceived as a remarkable factor.

The only workable principle is, so far, to place the sources of the odors far enough from anybody who could feel disturbed, and to pay attention to the prevailing wind direction. Also diluting the emissions with a large air flow promises so be an effective way to avoid complicated and expensive technical measures.

Encapsulating of olfactorily relevant asset areas is only theoretically the ideal method to reduce the emission. Within an enclosure, damp and an oppressive atmosphere can arise, so that the inner materials of the capsule produce a strong mechanical stress. Encapsulating even brings about a noteworthy explosion hazard.

For encapsulation to be viable, there must be some way to exhaust the spent air. Odorants remain inside the medium and tend to leak at the next suitable spot. The encapsulated space is never really gas-proof, and at some spots substances may leak out at considerably higher concentrations than they would do without the made efforts to hold them back.

There are three different ways exhausted air may be treated:

  • chemical treatment
  • physical treatment
  • biological treatment

Famous quotes containing the words legislative and/or provisions:

    “Let reverence for the laws, be breathed by every American mother, to the lisping babe, that prattles on her lap—let it be taught in schools, in seminaries, and in colleges;Mlet it be written in Primers, spelling books, and in Almanacs;Mlet it be preached from the pulpit, proclaimed in legislative halls, and enforced in courts of justice.”
    —Abraham Lincoln (1809–1865)

    “Drinking tents were full, glasses began to clink in carriages, hampers to be unpacked, tempting provisions to be set forth, knives and forks to rattle, champagne corks to fly, eyes to brighten that were not dull before, and pickpockets to count their gains during the last heat. The attention so recently strained on one object of interest, was now divided among a hundred; and, look where you would, there was a motley assemblage of feasting, talking, begging, gambling and mummery.”
    —Charles Dickens (1812–1870)
