One in a thousand! Environmental protection "special forces" seek pollution control
Nanjing Municipal Bureau of Ecology and Environment organized the establishment of the country's first team of olfactory experts in the petrochemical industry
Odors directly affect the lives of ordinary people, and the production of odors is also a signal of environmental pollution.
Smells are engaged in a "smell" job. They "sniff" the type and concentration of odorous gases with their noses, and use their noses to "convince" pollution.
Recently, the Nanjing Municipal Bureau of Ecology and Environment organized and trained a group of new olfactory discriminators. This group of employees from the Nanjing petrochemical industry formed the first team of olfactory discriminators in the petrochemical industry in China.
Becoming an olfactory expert means that they need to say goodbye to spicy food such as hot pot and malatang in order to maintain a keen sense of smell.

Solve the problem of peculiar smell disturbing people by smelling
Smelling division is also called "smell smell division", which is a profession that professionally measures the concentration of odor.
According to the procedure, a bottle of "odorous odor" has to go through three stages of sampling, laboratory inspection, and smell identification. level of conclusion.
At the odor identification scene in each environmental monitoring, the nose of the sniffer can collect first-hand information for the law enforcement of odor pollution.
As early as 2020, the Nanjing Municipal Bureau of Ecology and Environment launched a team of olfactory experts. Through the cooperation with the Nanjing Environmental Monitoring Center of Jiangsu Province to adopt weekly irregular on-site olfactory and other methods, the sensitive points of the Siliu community and the key industries in the New Materials Science and Technology Park have been identified. On-site monitoring of odorous pollutants and volatile organic compounds in the factory boundary of the enterprise is carried out to provide support for patrol inspection and law enforcement monitoring.
"On-site olfactory identification can promote the transformation of the current 'emission standard' governance system to a 'mass perception' governance system, and overcome the objective problem of 'the human olfactory threshold threshold is lower than the monitoring value and the emission standard value'." Nanjing Municipal Bureau of Ecology and Environment Yuan Jinhui, deputy director of the Atmospheric Division, introduced.
Through on-site olfactory identification to identify the source of pollution, combined with comprehensive treatment to improve environmental quality, from January to May this year, the concentration of odor factors, VOCs concentration, and the number of petition complaints at Siliu Station all dropped significantly, truly realizing the improvement of environmental quality and public happiness. Double boost.
Professional training with certificates to improve the ability to smell and distinguish
"The olfactory discriminators selected within the industry can better understand the internal situation and technological level of the enterprise, and play an important role in improving the pollution control level of the enterprise." Yuan Jinhui said.
In order to further play the role of olfactory experts in pollution control, the Nanjing Municipal Bureau of Ecology and Environment recently organized the first batch of olfactory experts in the petrochemical industry in the country.
Smell-discriminators do not have a good sense of smell. They must also pass special training and obtain a smell-discriminator qualification certificate.
Recently, the Nanjing Municipal Bureau of Ecology and Environment, the Nanjing Environmental Monitoring Center of Jiangsu Province, and the Tianjin Ecological Environmental Protection Industry Association jointly held the first special training course on "Odor Pollutant Monitoring Technology" for key enterprises in 2022.
In the practical operation class, with the sound of the motor of air preparation, the flat odor identification bag quickly became stronger, and the 5 cm needle and 100 ml needle tube shuttled on the operating table in an orderly manner. The improvement of students' operational ability.
Through the training, 48 trainees from the Nanjing petrochemical industry finally obtained the olfactory distinguisher certificate, which means that this team of odor distinguishers was officially born.
They will actively promote the prevention and control of VOCs and odor pollution in their respective fields, achieve refined environmental management standards, and play an important role in building an A-level enterprise in heavy pollution weather and emission reduction performance and Sinopec's waste-free enterprise.
Use real feelings to clear the blind spot of pollution control
"We all ate white porridge this morning." Teng Hui from Nanjing Yangzi Petrochemical Co., Ltd. is one of the new batch of olfactory discriminators. The day before the task, she was asked not to wear makeup, eat hot pot, or even eat hot pot. Use soap.
The sensitivity of the nose is self-evident for the importance of the nose.
"The selection age of the olfactory division is controlled under 45 years old. In order to ensure good physical function, it is required not to smoke, not drink alcohol or even stay up late. Before performing the task, it is not allowed to eat heavy-tasting food." Nanjing Yangzi Petrochemical Co., Ltd. Ren Yaojie, deputy manager of the safety and environmental protection department, said.
Under stringent standards, only 48 out of 7,000 employees meet the standards.
As a member of "One in a Thousand Miles", Teng Hui was nervous and looking forward to it.
Before becoming a sniffer, she was a full-fledged hot pot lover, and now the important mission on her shoulders has made her voluntarily put aside her love for hot pot.
Why use the nose to identify odors, not instruments?
"There are thousands of odorous substances. When the concentration of some substances is very low, the instrument cannot detect them, but people can smell them. People's sense of smell is more warm and representative, and they can empathize with the whistleblower." Yuan Jinhui explained. .
In the handling of odor disturbing cases, it is often encountered that the data measured by the machine meets the standard, but the surrounding residents feel the presence of odor.
At this time, the role of the olfactory discriminator is highlighted.
Through the determination of odors by the olfactory discriminator, the blind area of the machine threshold is made up, and it complements the instrument detection. From the standpoint of the residents, the level of pollution control can be improved with real feelings.
"In the next step, we will promote it in the city's industrial parks and some key enterprises, expand the team of olfactory experts, and effectively solve the problem of peculiar smells disturbing the people." Yuan Jinhui said.
