Arzamas is a city located in Nizhny Novgorod Oblast, Russia. It is situated on the banks of the Tyosha River and has a population of approximately 105,000 people. The city is known for its rich history, beautiful architecture, and cultural heritage. However, like many other cities around the world, Arzamas is also affected by light pollution.

Light pollution is the excessive and misdirected artificial light that is emitted into the atmosphere, causing a disruption to natural nighttime environments. It affects not only the sky but also the natural behavior of animals and the health of humans. Light pollution is caused by various factors, including street lighting, building lighting, and vehicle headlights.

In Arzamas, light pollution is mainly caused by street lighting and building lighting. The city has a developed infrastructure and a well-organized public transport system, which requires a lot of lighting at night. Additionally, many public and private buildings are illuminated throughout the night, including churches, monuments, and commercial buildings. All of these factors contribute to the excessive light pollution in the city.

Despite the light pollution, Arzamas is still a beautiful city at night. The city's landmarks, such as the Cathedral of St. John the Baptist and the Spasskaya Tower, are illuminated with bright lights, creating a spectacular sight. The streets of Arzamas are also well-lit at night, making it easy and safe for pedestrians to walk around.

The people of Arzamas are generally aware of the impact of light pollution on the environment and are taking steps to reduce it. For instance, the city has introduced a program to switch off streetlights during certain hours of the night when they are not needed. Additionally, some private businesses have also started to turn off their lights after business hours.

Arzamas is also home to several industries, including the manufacturing of machinery, furniture, and textiles. These industries are known for their high energy consumption, which contributes to the city's light pollution. However, the local authorities are working with the industries to find ways to reduce their energy consumption and, in turn, reduce light pollution.

In terms of the estimated amount of light pollution in Arzamas, it is difficult to provide an exact figure. However, according to recent research, the city is experiencing a moderate level of light pollution, with a sky brightness of approximately 17.5 magnitudes per square arcsecond. This level of light pollution can have negative effects on the environment and human health, such as disrupting the natural circadian rhythm and increasing the risk of certain diseases.

Arzamas is a beautiful city with a rich cultural heritage, but it is also affected by light pollution. The excessive and misdirected artificial light emitted by street lighting and building lighting is the main cause of light pollution in the city. However, the people of Arzamas are aware of the impact of light pollution and are taking steps to reduce it. With the cooperation of the local authorities, industries, and individuals, it is possible to reduce the level of light pollution in the city, creating a more sustainable and healthy environment for everyone.
