Environmental Environmental Pollution Monitoring Center

Environmental Environmental Pollution Monitoring Center continuously monitors air and water environments, noise and vibrations in order to understand the current situation of the suitability of environmental standards and to confirm the effects of environmentalconservation measures. Monitoring of air and water environments has been conducted since around the 1960s, when industrial pollution had become a major social problem, and road traffic noise surveys have been conducted since the 1980s.
In addition to publishing the current atmospheric environment measurement data (updated every hour in principle) will be released, and the results of the results of the air / water environment, noise and vibration surveys are compiled and published in monthly reports and annual reports. , And widely disseminated as environmental information.

Monitoring the air environment measures air pollutants, harmful air pollutants, dioxins, and spatial radiation doses.
Atmospheric pollutants are measured 24 hours a day at 27 locations in the city, and the current status of atmospheric environment is announced on our website. (Article 22 of the Air Pollution Control Law)
Hazardous air pollutants are measured once a month at three locations in the city. (Article 18-44 of the Air Pollution Control Law)
Dioxins are measured twice a year at six locations in the city. (Article 26 of the Special Measures Law Concerning Dioxins)
Space radiation dose is measured 24 hours a day on municipal land in the west of France, Hodogaya Ward, and the current status of spatial radiation is published on our website.

Photochemical smog is caused by chemical reactions when causative substances, mainly nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted from automobiles and factories undergo a chemical reaction when exposed to ultraviolet rays contained in sunlight. , Photochemical oxidants, a secondary contaminant, are generated. This phenomenon is called photochemical smog [Kanagawa Prefecture] (outside site) because the concentration of photochemical oxidant increases, it becomes white hazes.

A photochemical smog advisory is issued by Kanagawa Prefecture.
When photochemical smog advisory is issued, we alert citizen to prevent damage from photochemical smog.

If you experience any damage caused by photochemical smog, please consult your nearest medical institution.
Environmental Environmental Pollution Monitoring Center reports the damage situation to Kanagawa Prefecture.
From 8:30 to 17:15 (Saturdays, holidays, nights are the next open day), please inform the Environmental Environmental Pollution Monitoring Center of the following matters.

• Name, age, grade, gender, contact information, number of people, etc.
• Symptoms (irritation of eyes and throat, dizziness, numbness, dyspnea, etc.)
• Status of treatment, etc.

Monitoring of the water environment measures the water quality and dioxins of public water bodies and groundwater.
The water quality of public water bodies is measured once a month at 11 locations in rivers and 7 locations in the sea area based on the public water body water quality measurement plan formulated by Kanagawa Prefecture. (Article 1066 of the Water Pollution Prevention Act)
Water quality of underground water is measured once a year. (Article 1066 of the Water Pollution Prevention Act)
Dioxins measure the pollution status of water quality (including the bottom of the water bottom) once a year at six locations in the city. (Article 206 of the Special Measures Law for Dioxins)

The noise monitoring measures road traffic noise, Shinkansen noise noise and vibration.
Road traffic noise monitors 160 locations in a five-year plan. We measure about 30 sites every year. (Article 18 of the Noise Control Law)
Shinkansen noise and vibration are measured at two of the eight measurement lines along the Tokaido Shinkansen every year. (Article 16, Paragraph 1 of the Basic Environmental Law)
