Chugai Technos Corporation

We utilize our plant measurement technologies, such as exhaust gas measurement, that we have developed over many years to provide a wide range of services, including performance tests and trial operations. We also provide our own unique technologies for the analysis of various gases and amines related to decarbonization.

In order to determine the suitability of environmental standards for air quality in the general environment and to understand the current situation in environmental impact assessments, we conduct surveys of sulfur dioxide ( _SO2 ), nitrogen dioxide ( _NO2 ), suspended particulate matter (SPM), carbon monoxide (CO), fine particulate matter (PM2.5), and harmful air pollutants, as well as make predictions and evaluations and propose environmental conservation measures.
Air quality surveys involve installing air measurement vehicles such as those shown in the photograph to conduct meteorological observations and measure the concentration of air pollutants.

We conduct surveys and analyses on items related to protecting human health and preserving the living environment, measure river flow rates, and measure groundwater levels, with the aim of determining the suitability of environmental standards for rivers, lakes, and oceans, and grasping the current situation for environmental impact assessments, etc. We also predict and evaluate water quality and propose environmental conservation measures.
Furthermore, by installing water quality measuring equipment like the one in the photograph in rivers and other water bodies and building a constant water quality monitoring system (using mobile phone networks), it is possible to grasp the current water quality, such as pH and turbidity, in real time (the acquired data can also be graphed and published on the web).

We conduct measurements of noise and vibration generated by various equipment in construction sites and factories, and from transportation such as roads, railways, and aircraft, in accordance with the Noise Regulation Act, Vibration Regulation Act, JIS, and various manuals.
To implement measures to reduce noise and vibration, it is important to accurately understand the source of noise, propagation path, and the condition of the object to be protected.
Therefore, in addition to general measurements, we use frequency analysis and sound source detection equipment, as well as constant monitoring systems that use communications, to propose optimal measurement methods according to the purpose and situation. At the same time, we also conduct analysis, simulations, and reduction measures based on measurements.
We also receive commissions from many local governments for "constant automobile noise monitoring" (area evaluation) and traffic volume surveys.

• 1 Designated investigation organization under the Soil Contamination Countermeasures Act

  Designation number: 2003-8-3029 Designation update date: April 1, 2020

• 4 Soil gas survey

  Volatile organic compounds (VOCs) are analyzed by collecting soil gas approximately 1m above the ground surface.
  Due to their volatility, volatile organic compounds remain in the soil as gases, and by analyzing their concentration, areas where they may have seeped in (areas with a high possibility of contamination) can be identified.
  Inspection method: PID gas chromatograph

• 5 Surface soil survey

  For heavy metals, pesticides, etc., soil samples are collected up to 50 cm from the location of any risk of contamination on the ground surface and then analyzed.
  Heavy metals, pesticides, etc. are relatively unlikely to penetrate or disperse deep underground, and tend to remain near the source of contamination. The presence or absence of soil contamination can be assessed by collecting and analyzing soil that contains these substances.
  Testing methods: Headspace GC/MS, ICP optical emission spectrometry, ICP mass spectrometry, etc.

• 6 Depth soil survey/Groundwater survey

  After contamination is confirmed by soil gas surveys and surface soil surveys, a survey is conducted in the depth direction to identify the presence or absence of contaminants and their depth distribution, etc. If groundwater contamination is confirmed, the groundwater is sampled and analyzed.
  Testing methods: Headspace GC/MS, ICP optical emission spectrometry, ICP mass spectrometry, etc.

• 1 Bioremediation

  Purification is carried out by adding chemicals that activate microorganisms that can break down pollutants, increasing their decomposition activity.
  The main chemicals used are upcycled by-products from the food manufacturing process, making them an environmentally friendly and sustainable anti-pollution measure.
  Compared to other methods, purification can be achieved at a lower cost, and it can be carried out even in small areas or in operating factories.
  Based on the information and analysis obtained from laboratory tests and test construction, we comprehensively determine the optimal injection method, amount of chemical to be injected, injection frequency, etc. We provide total support from construction plan proposal to construction management, effect monitoring, and completion of countermeasures to achieve maximum effect at minimum cost.

• 2 Pumping and treatment

  Contaminated groundwater is pumped up and treated above ground before being released or returned underground.
  We propose equipment and systems that are appropriate for the discharge destination standards and site. These equipment and systems are suitable for reducing high-concentration groundwater contamination and preventing the spread of contamination outside the site. In addition, after the pumping and treatment equipment is installed, the groundwater quality and water level can be monitored.

• 3 Excavation and removal

  The contaminated soil is excavated and removed, and the area is backfilled with clean soil. This method is applicable to most hazardous substances, and compared to other methods, it can shorten the construction period on site. The excavated contaminated soil is disposed of at a contaminated soil treatment facility certified by the Ministry of the Environment.

• 4 Insolubilization (in-situ injection mixing method)

  Chemicals are mixed into the contaminated soil to make the heavy metals insoluble, preventing harmful substances from leaching into the groundwater.
  By selecting the right chemicals, various types of contamination can be dealt with, and the cost is lower than excavation removal.

• 5 Soil gas suction

  Volatile organic compounds that have evaporated underground and become gaseous are collected by suction and adsorbed onto activated carbon for processing.
  This is effective in reducing the concentration of pollutants at the source of contamination and in recovering pollutants.

• 6 Chemical decomposition

  Volatile organic compounds and other substances are decomposed using the oxidizing power of chemicals (such as hydrogen peroxide).

Welding fume measurement

It has become clear that "welding fumes" generated during work such as metal arc welding may cause health hazards to workers, including neurological disorders. In response to this, the Ministry of Health, Labor and Welfare has revised the Enforcement Order of the Industrial Safety and Health Act and the Regulations for Prevention of Harm from Specified Chemical Substances (Specific Chemical Substances Regulations), and has issued new public notices.
From April 1, 2021 (with some transitional measures), employers who continue to perform work such as metal arc welding in indoor workplaces will be required to measure welding fume concentrations as one of the measures to prevent health hazards.
Our company provides one-stop service from on-site inspections to measurements and analysis, with qualified work environment measurement specialists.
*Requests for quotes and consultations regarding measurements are accepted via the "Inquiries" section on the website.

Mask fit test

From April 1, 2023, in order to prevent health problems caused by "welding fumes" generated during work such as metal arc welding, workers who work continuously in indoor workplaces will be required to undergo a fit test once a year to check whether they are wearing protective equipment properly.
In addition, from April 1, 2024, if the results of work environment measurements are classified as Class 3, if the employer's implementation of improvement measures is not effective and the workplace is again classified as Class 3, or if a workplace is deemed to be Class 3 again after hearing the opinions of work environment management experts, it will be mandatory to conduct a fit test once a year to check whether the respiratory protective equipment is being worn properly.
We carry out testing using fit testing equipment.
