Scope of Activities:

  • Situated at Ahmedabad in Gujarat, the National Institute of Occupational Health (NIOH) conducts research on occupational and environmental health to provide a safe, healthy and comfortable work environment and living, through multidisciplinary approach viz. education, service and related activities.
  • NIOH has two Regional Centres at Kolkata and Bangalore to cater the need of Eastern and Southern parts of the country.

Thrust Areas:

The following are the thrust areas of NIOH

  • Epidemiological and environmental monitoring and corollary toxicological studies in hazardous occupations for recognition and evaluation of risk factors
  • Development of tools for early diagnosis of health impairment and design of appropriate intervention measures for the prevention of hazards at work places.
  • Occupational and environmental epidemiology
  • Toxicology (metal, pesticide, reproductive, geno and neurobehavioral)
  • Environmental pollution (air, water, noise, thermal)
  • Development of safety norms (chemical physical agents)
  • Operational research
  • Women and children health
  • Agricultural health
International Recognition:

  • NIOH is a declared WHO Collaborating Centre for Occupational Health in South-East Asia region.
  • Participating institute for International Programme on Chemical Safety (IPCS) - a programme organized jointly by WHO, International Labor Organization (ILO) and United Nations Environmental Programme (UNEP).
Human Resource Development :

One of the major functions of this Institute is to develop human resources. In this direction, NIOH has carried out number of training programmes. These training programmes were carried out for medical officers working in the ESIS, PHCs, and industries, industrial hygienists, medical inspectors of factories, factory inspectors, safety officers, NGOs, etc. The period of these training programmes ranges from one week to three months. NIOH has also started three months certificate course of Associate Fellow of Industrial Health (AFIH) for the medical officers working in the industry in collaboration with Mahatma Gandhi Labour Institute, Ahmedabad.
Recognition for Doctorate/Masters by a University:

The M.S. University, Vadodara; Gujarat University, Ahmedabad; University of Kolkata and University of Jadavpur have recognized the Institutes’ scientists as Ph.D. guides.

Major Achievements:

Significant achievements of NIOH are the following
  • Undertook studies on the industries such as Slate Pencil and Agate Industry, Quartz Grinding,
    Stone Quarries, Mica Processing and also developed an exhaust system with Bag filters to
    reduce the risk of silica exposure.

  • Studies in various industries viz., Asbestos-Cement, Asbestos Mining, Milling, etc. over a
    period of time reported reduction in fiber levels from as high as several hundred fibers per
    cubic centimeter of air to less than permissible levels. It also helped Government in reducing
    the permissible level from 2 fibre/ml to 1 fibre/ml.

  • First to show through epidemiological studies a very high prevalence byssinosis especially
    in blow (30%) and card rooms (38%) of textile mills. Byssinosis was also reported for the first
    time in Jute Mill workers.

  • Reported low prevalence of pneumoconiosis and absence of more severe cases of
    pneumoconiosis in Indian coal miners. It also reported very high prevalence of non
    pneumoconiotic respiratory morbidity in coal miners.

  • Successfully undertook gloves awareness programmes in different tobacco cultivating
    regions. The Bureau of Indian standards, Tobacco Board, Ministry of Commerce (Government
    of India) has acknowledged the development for incorporation in standards and specification
    of use by the tobacco farm workers of AP and Karnataka.

  • Demonstrated very high sound pressure levels in various industries, ranging from 102-114
    dBA in textile industries, 93-103 dBA in pharmaceutical firms, 90-102 dBA in fertilizer plants,
    90-119 dBA in oil and natural gas complexes in Bombay High, 60-102 dBA due to road traffic
    in Ahmedabad city, 90-102 dBA in surface rail traffic, 70-111 dBA in metro rail, 90-112 dBA
    for air traffic.

  • Conducted evaluation of occupational exposures to metals in a number of industries such
    as printing press, type foundries, ceramic and pottery foundries, battery reconditioning
    shops, garage workers, mining and smelting plants, silver foundries and silver refinery, etc.

  • Study on insecticide hexachlorocyclo-hexane (HCH) was of its own kind that covered all
    the four HCH manufacturing units in the country resulting in Beta-HCH being taken as the
    marker for cumulative exposure for HCH and lindane for immediate past exposure.

  • Designed a prototype of a ploughing device for better tillage.

  • Research and experimental studies that helped in the development of various intervention
    strategies and engineering control devices in order to reduce the exposure level in the work
    environment.

  • Designed dust control device consisting of blower, and bag filters for traditional grinding
    machines in agate industry. Dust control device to reduce silica dust in small silica flour mill
    units was developed using ACGIH ventilation guidelines.

  • Established that glycerol hyperhydration allows maintaining an enhanced fluid reservoir,
    thereby reversing cardiovascular and thermoregulatory challenges during work-heat
    stress.

  • Developed two (portable and mobile) local exhaust ventilation (LEV) units in collaboration
    with the Rural Technology Institute, Gandhinagar, India.

  • Maiden study on cardiac toxicity due to exposure to methomyl, a carbamate pesticide.

  • Non-occupational exposure to silica dust in the vicinity of agate (Gujarat) and slate pencil
    (M.P.) industries was reported for the first time. Several cases of non-occupational silicosis
    were also reported.
