Environmental Environmental Pollution Monitoring Center

Environmental Environmental Pollution Monitoring Center continuously monitors the atmosphere, water environment, noise and vibration to understand the current status of environmental standards related to the living environment and to confirm the effects of environmental measures related to conservation. Monitoring of the atmosphere and water environment has been conducted since the 1960s, when industrial pollution had become a major social problem, and road traffic noise surveys have been conducted since the 1980s.
On this website, the current atmospheric environment measurement data (updated every hour in principle) will be released, and the results of surveys on air, water environment, noise and vibration will be compiled and published in monthly reports and annual reports. , And widely disseminated as environmental information.

Monitoring of the air environment measures air pollutants, harmful air pollutants, dioxins, and spatial radiation doses.
Air pollutants are measured 24 hours a day at 27 locations in the city, and the current status of the atmospheric environment is announced on the 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 Act)
Dioxins are measured twice a year at six locations in the city. (Article 26 of the Act on Special Measures against Dioxins)
Space radiation doses are measured 24 hours a day on municipal land in the west of Buddha, Hodogaya Ward, and the current status of spatial radiation is published on our website.

Photochemical smog occurs when the causative substances mainly composed of nitrogen oxides (NOx) and volatile organic compounds (VOCs) emitted from automobiles and factories are irradiated by ultraviolet rays contained in sunlight and undergo chemical reactions. Photochemical oxidants, a secondary contaminant, occur. This phenomenon is called photochemical smog [Kanagawa Prefecture] (outside site) because when the concentration of photochemical oxidants increases, white haze becomes applied.

The photochemical smog advisory will be issued by Kanagawa Prefecture.
When a photochemical smog advisory is issued, we alert citizens to prevent damage caused by photochemical smog.

If damage that seems to be caused by photochemical smog occurs, consult your nearest medical institution.
Environmental Environmental Pollution Monitoring Center reports the damage to Kanagawa Prefecture.
From 8:30 to 17:15 (Saturday, holiday, nighttime on the next open day), please inform the Environment Environmental Pollution Monitoring Center of the following matters.

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

Monitoring of the water environment measures the quality of public water bodies and groundwater and dioxins.
The water quality of public water bodies is measured once a month at 11 rivers and 7 sea areas based on the public water bodies water quality measurement plan formulated by Kanagawa Prefecture. (Article 106 of the Water Pollution Control Act)
Water quality of underground water is measured once a year. (Article 106 of the Water Pollution Control Act)
Dioxins measure the pollution status of water quality (including the bottom of the water) at six locations in the city once a year. (Article 206 of the Act on Special Measures against Dioxins)

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