Internet companies moved to new locations, white-collar workers could not bear the strange smell of the surrounding, have to wear masks to work. Recently, Ms. Pan of a company in Optics Valley reflected her concern.

Ms. Pan said that at the beginning of this month, her company moved to the Modern Optics Valley World Trade Center on Guanggu Avenue. In recent days, there has been a pungent odor floating around the neighborhood. Colleagues have been wearing masks in their offices. They still feel unwell. Some people even vomit, and they ask for leave.

On the morning of the previous day, a reporter from Chutian Metropolis Daily came to the intersection of Guanggu Avenue and Guannanyuan Road and did not smell the pungent odor. Ms. Pan came to Wuhan Cono Biotech Co., Ltd. opposite to the reporter and approached the company's fermentation workshop to smell some odors. Ms. Pan said that this odor is what the company usually smells.

The person in charge of the biotech company stated that the company uses bean pods, rice, peanuts, corn and other foods to ferment and produce feed. In the fermentation process, more or less certain odor will be produced, but it is non-toxic and harmless. Previously, the company has invested capital in the introduction of gas purification facilities, and the odor has faded a lot. In the future, they try to stagger the production time with the surrounding company's work time.

After receiving the report from Ms. Pan, the staff of the Environmental Protection Branch of Donghu High-tech Zone came to the factory the day before. According to reports, since last year, the environmental protection department has repeatedly come to the company, and the inspection found that the plant's pollution prevention and control facilities are in normal operation and discharge standards. On the same day, the staff sampled again for testing.
