Thiophanate-methyl
Identification Number: CASRN | 23564-05-8

  Substance Attributes

• Birth/Developmental

  Known to effect development of fetus.

• Metabolic Interference or Disruption

  Interferes with human metabolism. This can be a very serious thing. Some of these interference mechanics are well established. However, often long term effects and health consequences remain largely unknown. Additionally an emerging area of concern and one that is not currently studied, is the combined synergistic effects these metabolically disrupting chemicals have on human health.

  
  

  Metabolic interference happens when the substance produces highly reactive and often damaging intermediates during detoxification or when the substance binds to specific enzymes, important structural groups on molecules, receptors and membranes or targets DNA or mimics key nutrients.

• Exposure Produces Health Symptoms

  Symptoms maybe short term or long term depending on the exposure duration and intensity and effects areas like Cardiovascular, Gastrointestinal, Cognition, Fatigue. A substance with this attribute may cause an allergic skin reaction, serious eye irritation, allergy or asthma symptoms or breathing difficulties if inhaled.

• Toxic to Wildlife

  May kill plants, fish, birds or other animals and insects or may be very toxic to aquatic life with long lasting effects. This then effects delicate environmental ecology and food supply in ways we don't fully understand yet.

These attributes are ONLY based on peer-reviewed evidence. See link to Data Sources below. Everyone benefits from knowing this stuff. Please Share.

• DESCRIPTION: Thiophanate-Methyl (TM) is a systemic fungicide. It was first registered to be used as a fungicide by the EPA in 1973. It is effective against a wide range of fungal pathogens including: eyespot and other diseases of cereals; scab on apples and pears; Monilia disease and Gloeosporim rot on apples; Monilia app. On stone fruit; Canker on fruit trees; powdery mildews on pome fruit, stone fruit, vegetables, cucurbits, strawberries, vines, roses. Thiophanate methyl is also used on almonds, pecans, tea, coffee, peanuts, soya beans, tobacco, chestnuts, sugar cane, citrus fruit, figs, hops, mulberries, and many other crops.

  From Safe Work Australia and the Hazardous Substances Information System (HSIS) in Australia:
  
  Suspected of causing genetic defects. Harmful if inhaled. May cause an allergic skin reaction. Very toxic to aquatic life with long lasting effects | Chronic Health Hazard Environmental Hazard General Health Hazard | A Hazardous Substance that may be found in the Australian Workplace. Check with your employer or health and safety officer. Stay informed and become aware of the dangers that surround you. This chemical is included on the list of recognised hazardous chemicals from the Safe Work Australia - Hazardous Substances Information System (HSIS) that is based on the Globally Harmonised System of Classification and Labelling of Chemicals (GHS)
  
  Work Health and Safety (WHS) Regulations are the basis for hazardous chemicals regulations in Commonwealth, State and Territory jurisdictions in Australia. Under the model WHS Regulations, manufacturers and importers of substances, mixtures and articles supplied for use in workplaces are required to determine whether they are hazardous to health and safety before supply. The model WHS Regulations mandate that the hazards of a chemical as determined by the Globally Harmonised System of Classification and Labelling of Chemicals (GHS) must be included in safety data sheets and on labels. There are transitional arrangements in place for moving to the GHS-based system.
  
  The GHS Hazardous Chemical Information List contains chemicals classified by an authoritative source (such as the European Commission or NICNAS) in accordance with the Globally Harmonized System of Classification and Labelling of Chemicals (the GHS). This list contains the vast majority of chemicals currently in HSIS. This list and its detail are regularly updated by Work Safe Australia. The model Work Health and Safety (WHS) Regulations require chemicals to be classified in accordance with the Globally Harmonised System of Classification and Labelling of Chemicals (GHS). However transitional arrangements allow use of classification information in HSIS derived from the Approved Criteria until the 31 December 2016.

  Health Associations

Mostly focused on Health Implications of Long Term Exposure to this substance

• SYMPTOMS: Thiophanate-methyl can cause skin, eye and respiratory irritation, shortness of breath, chest pains, burning eyes, dizziness, and fatigue.
• POSSIBLE HEALTH CONSEQUENCES: Thiophanate-methyl is likely a human carcinogen. It increases of risk of liver tumours in mice. Thyroid/parathyroid weights were increased The developmental toxicity studies showed the decreased fetal body weight and increases in skeletal variations in the fetuses of rabbits exposed to thiophanate-methyl. It induced histopathological damages in rat thyroid and adrenal glands. |
• ACTION OF TOXIN:
• TOXIN SITES OF ACTION IN CELL: "Membrane"
• Additional Exposure Routes: This is a man-made compound that is used as a pesticide.
