At the end of last month, the Standing Committee of the Beijing Municipal People’s Congress scrutinized the “BEIJING AIRCRAFT POLLUTION CONTROL PROVISIONS (Draft)” to require a maximum fine of 20,000 for open-air grilling in the restricted area, which is four times the existing RMB 5,000 in Beijing. However, under the temptation of having a monthly income of over 20,000 yuan in a barbecue stall, there is still a steady stream of people taking risks.

So, where are the Beijing barbecue stalls? What are the effects of untreated barbecue fumes on the air? Who should monitor the air pollution caused by barbecue stalls? The reporter visited and investigated several open-air barbecue stalls. The survey found that there was a vacuum zone in the contest between open-air barbecue and reality supervision.

"Don't dare to open windows on the 16th floor"

Five kilometers outside the East Fifth Ring, Yangzha Huandao to the east, fruit stalls and barbecue stalls along the north side of Chaoyang Road, occupying the pedestrian path and part of the driveway. On a tricycle, the barbecue grill straddled the tricycle and there were five or six guests around the skewer stalls. The stall owners were busy greeting them. The gluten, skewers, fish tofu, steamed buns, and barbecue grills about 1.5 meters long are filled with various skewers to be grilled.

On the south side of Chaoyang Road, the two hotels are filled with white plastic tables and chairs and hold parasols waiting for guests. Two or three meters long barbecue grill placed in front of the hotel, rising smoke and the smell of barbecue exudes business. The skewers were naked and the fumes quickly dissipated in the air under the effect of powerful fans.

Outside the west gate of Jingtongyuan Community, a restaurant will place grills along the street, and diners have filled most of the tables and chairs. As to whether or not the open-air barbecue is illegal, skewers shook their heads. "I don't care about that, I just want to skewer."

In the one-kilometer radius around Yangzha Huandao, barbecue stalls are not uncommon. Three Beer Squares surround the island, and in the beer square, there are barbecues.

“This is not an open-air barbecue, we don’t have a house.” The chef of a skewer stood in a small wooden house. The fumes in the grill made him have to blink. “We’re not occupying the road. The venue was rented and there was no problem.” In the wooden house, there was no smoke processing equipment, the barbecue grill was tightly clinging to the windows, the walls were darkened and the smoke was diffuse.

In January of this year, Beijing Municipal Environmental Protection Bureau drafted the "Beijing Municipal Air Pollution Prevention and Control Regulations (Draft for Ratification)", there are provisions stipulating that "in the open air barbecue in urban areas, riding a wall (window) barbecue".

The reporter’s investigation found that there are 13 large and small barbecue stalls in a radius of one kilometer around Yangzha Huandao, all of which are barbecue grills or barbecues with untreated smoke.

Outside Tiantongyuan North District II, several small Mazars are placed in front of the community, and several estate agents are sitting next to the barbecue stalls. The large skewers are placed on the table. Near the residential wall, white smoke rising from the grill, only four or five meters away from the nearest residential window. A resident said, “There are a lot of such open-air barbecue stalls in Tiantongyuan. They don’t pollute the air, and they make the residential environment particularly dirty.”

The same situation also plagued Liu Qiang, who lives in the four districts of Wangjing West Park. She smoked smoke in the open air barbecue stalls downstairs every evening. “Don’t dare to open windows on the 16th floor, or smoke enters the house. How much pollution, we can only keep the windows closed."

Many stall owners said that barbecue stalls are concentrated in areas where residents are concentrated. "The residents have a large concentration of passengers. Only in this way can they be eaten, or else they should be open around the university. This is also a good choice."

There must be a mobile barbecue stall at the transport connection

Every evening from 10:00 pm to 10:00 pm, the northwest exit of Shuangjing Station on Line 10 will always be illuminated by the lights of mobile vendors. The “shelves” of mobile vendors are all tricycles. There are also pedal and electric vehicles. Under normal circumstances, at least two of the five or six mobile booths next to the subway station are related to barbecue - a grilled noodles, a grilled fish tofu and gluten.

The tofu and gluten of grilled fish used the same apparatus and methods as the shish kebab. The smoke produced was much stronger than the cold noodles, and the number of diners attracted was relatively high. In the oven about one meter long, more than a dozen of gluten and six skewers of fish tofu were roasted on a red-hot charcoal fire. Five skewers of fish tofu were placed on the right end of the oven. In less than five minutes, the diners coming out of the subway emptied them all.

In the northeast mouth of Shuangjing Station is a similar scene. Uncle Yang, who lives nearby, revealed that in the northeastern mouth of Shuangjing Station, as long as it does not rain, these mobile stalls for the sale of barbecued foods will definitely appear. “One of them specializes in selling kebabs and smokes every day. of."

Sanyuanqiao subway station outside the C mouth, is the aggregation of mobile vendors, all kinds of small barbecue stalls not only occupy the edge of the road outside the exit, and some even directly in the entrance to the station entrance and ground entrance and exit in the underground channel. The smell of barbecue pervades the entire passage.

From the northeast entrance of Sun Palace Station, about 2 kilometers away from Sanyuan Bridge, the mobile vendors also put on a “welcome welcome” battle. Most of them are barbecues, kebabs, cold noodles, grilled ham, etc. .

A stall owner said that the main reason for choosing the subway is to have a large flow of people. “Now it's hot. Most people buy some kebabs for dinner on our booth. There's more or less to make, and certainly not lose money anyway. And this place does not have to pay rent."

In addition, some of the traffic routes below the underpass overpass are also places where mobile barbecue vendors prefer. Under the Guangqumen Bridge, diners in mobile barbecue stalls in the southeast corner and northeast corner continued.

The residential area is heavier than the daytime pollution at night

The slogans claiming strict punishments for open-air barbecues were hailed for several years, but there have been no reports that stall owners have been heavily punished.

In Dongbai Street near Shuangjing Station, there are five barbecue stalls on a street less than 300 meters long. There is only one oven next to the door of its own restaurant, and the other four places the oven in close proximity to the road. On the sidewalk. A barbecue stall owner said that his colleagues have been very concerned about penalties for open-air barbecues. “On the internet, I’ve seen that the maximum penalty may be 20,000, but I think it’s not enough. These barbecue racks are added up to a few thousand dollars. How can they be fined? Twenty thousand people? But now everyone is careful. When they see the city management, they all go back to the table. It was not until then.” He also said, “The barbecue business is not doing well now, and the city is getting stricter.”

The smoke from several barbecue stalls caused many passers-by to cover their noses, and one resident said that the barbecue fumes will continue until the early hours before they gradually fade away.

Wang Yuesi, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, believes that in many communities, barbecues often occur, and the scale of booths varies. The impact on the residents upstairs or nearby has been considerable. Originally, it was necessary to open the windows to allow the air to circulate. As a result, all the people had come from the "barbecue". Barbecue is not completely burned, it will produce carbon monoxide, nitrogen oxides, sulfur oxides and so on. And barbecue stalls are in the evening, at this time there will be an inversion effect, the smoke emitted is not easy to spread, resulting in more serious than the daytime pollution.

Wang Yuesi's analysis of Beijing PM2.5 found that catering emissions can account for 10% to 15% of the PM2.5 source, and can reach 17% when it is high. Food and beverage sources are also a relatively important source of pollution in Beijing. The emissions from barbecues are part of the pollution from food and beverage sources, but the data does not specifically reflect the proportion of barbecues. “The barbecue definitely affects Beijing’s air pollution, and how specific the air impact is, and there is currently no specific study.”

City tube can not reach the barbecue thick smoke

The reporter dialed the Beijing Environmental Protection Bureau's environmental complaints and reporting service hotline 12369 as a citizen and complained about open-air barbecue stalls on the grounds of excessive smoke, affecting window opening and normal life. The staff member said, “Our environmental protection department has no enforcement power. The report of open-air barbecues is handled by the city management department.” The staff explained: “According to the relevant regulations of the 'Rulings of the Rule No. 83', there are barbecues for smoke exhaust facilities to the environmental protection departments. In general, barbecue stalls without smoke exhaust facilities, whether belonging to road occupation or not, are all returned to urban management.”

One stall owner on the roadside doing an open-air barbecue said, “Like we are racking stoves on the side of the road, we don’t actually let those stoves set up on the sidewalks in front of our own restaurant, and we’re not even on the sidewalk. For an open-air barbecue, there are times when city management comes. We have to pack things up and leave people at the door.

Whether or not open-air barbecue stall owners want to receive a share depends on the “mood” of the city management. More often, when the urban management team patrols, they will conduct verbal exhortations to the stall owners. “Say not letting here, let us quickly close up.” Another stall owner said that his barbecue grill had been taken away by the urban management team. "Finally, two cigarettes were sent and the shelves came back. When the law enforcement was severe, fines were also punished. But the penalty was not much, and the confiscated shelves were generally returned."

"This is actually not a scientific problem, but a management problem. Since there are relevant regulations and norms, we must supervise, inspect, and impose fines as soon as possible, and supervise open-air barbecues and barbecue sites that have not been treated," said Wang Yuesi. Now that some of the environmental issues, many phenomena are management is not in place. Barbecue has become a habit. For such a phenomenon, it is necessary to increase the intensity of guidance and law enforcement. At the same time, the illegal cost cannot be too low. First of all, from the food culture, we can advocate that the public try to eat as little as possible, especially on the roadside barbecue, which takes a long time. Helping people understand the dangers and impacts on human health and air quality needs the support and understanding of the mass consumers.

“The current situation is that environmental protection agencies believe that open-air barbecue is not the jurisdiction of the environmental protection department, but the urban management should be managed. The urban management department thinks that they are responsible for whether the booth takes business, and whether the pollution caused by whether it belongs to an open-air barbecue should be The environmental protection department will supervise it.” Wang Yuesi suggested that in terms of management, the environmental protection department should jointly enforce the law with the urban management department to avoid loopholes in each other and management.
