Of course, you need qualifications and relevant tests and certificates. In real life, there is odor pollution. Sewage and garbage cause environmental odor pollution, with various odors. Especially when a variety of smells are mixed together, it is difficult to complete the detection only by equipment. It is difficult to analyze and judge its impact on the environment and the degree of pollution by human sense of smell. Judging by the analysis of the smell, such a person is called? Sniffer? .

In foreign countries, this major is more vividly called? Do you smell that smell? Smelling bad smells is not a new occupation. 1994, the relevant departments of our government formulated the emission standard of odorous pollutants. Since then, the state began to conduct formal training and examination for odor sniffers, and issued professional certificates and unified numbering management. The occupation of smell sniffer has become more standardized and professional. Most sniffers work in environmental protection departments at all levels. The sniffer uses his nose to distinguish various smells, even unusual smells, so as to describe the smell grade and confirm whether it meets the requirements. Emission standard of malodorous pollutants? .

The judgment made by Master Wen Xiang is legally valid. If it is determined that the smell exceeds the standard, the relevant departments can order it to be dealt with according to law. The judgment of the olfactory owner provides technical support for environmental management decision-making. Landfills, sewage treatment plants, sewers and other places are the identification tasks of odor sniffers. Being an odor sniffer doesn't mean that the more sensitive your nose is, the better. On the contrary, smelly teachers are ordinary people's sense of smell. They are not as sensitive as others think. They must represent the sense of smell of ordinary people.

If the sense of smell is very sensitive, it is an objective reflection of the incorrect odor concentration, which will affect the judgment result. To be a smelly teacher, you need to undergo strict training and examination. First of all, candidates need to learn theory and master basic knowledge such as measurement methods and national standards of malodorous gases. After passing the written test, they need to conduct a series of on-site olfactory tests. Only through professional certification can you engage in related work. However, the professional qualification of smelly teachers is not lifelong. For physiological reasons, the sense of smell will decline with age. Therefore, smelly teachers must re-certify their professional qualifications every three years, and their age should not exceed 45.
