Carcinogens: ICMR to study samples
New Delhi: The Indian Council of Medical Research (ICMR) submitted a reply to the National Green Tribunal stating that it will soon initiate a study by collecting blood and urine samples of drivers to evaluate whether chemical compounds called TCEP, TCIPP and TDCIPP found in flame retardants materials used in the cars are potentially carcinogenic. The response comes in the wake of a study published in journal Environmental Science and Technology saying that cars have flame retardant chemicals considered potentially carcinogenic. The study was concerned about Tris (1-chloro-isopropyl) phosphate (TCIPP), Tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) and Tris (2-chloroethyl) phosphate (TCEP). Of these, ICMR has already recognised TCEP as a carcinogen. A bench headed by NGT chairman, justice Prakash Shrivastava, had sought details about the matter. Responding on July 22, ICMR said it intends to test 360 professional drivers by collecting their urine and blood sample to test for presence of the chemical compounds. The study could take at least 18 months. The proposal of ICMR-NIOH, Ahmedabad, would detail the study objectives, methodology, budget requirements, as well as timelines for conducting the research, ICMR told NGT. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Seniors Say This Drugstore Wrinkle Cream Is Actually Worth It Best Of Beauty Learn More Undo Some of the objectives would be to assess exposure of flame retardants and their metabolites among professional drivers and to compare biological levels of flame-retardants/their metabolites in "variable climatic conditions and vehicular stratification".

In terms of the proposal, completing laboratory analysis of biological samples, data processing, statistical valuation, exposure modelling, and reporting would require approximately 18 months," ICMR said. "Apart from the time period mentioned above, since a budgetary requirement of approximately Rs 85,32,800 is involved to conduct the proposed research study, due sanction and approval have to be obtained from the authorities concerned. Therefore, additionally, a period of nine months approximately would be required in obtaining the said requisite approvals/sanctions." Earlier in May, an ICMR report referred to several leading international agencies, including the International Agency for Research on Cancer under the World Health Organization and environment and toxicology institutes in the US and Europe having published systematic reviews identifying carcinogenic chemicals in flame retardants used in motor cars to which humans may be exposed through ingestion, inhalation or skin contact. The report said that only one of the compounds, namely TCEP, appeared on the list of potential carcinogens, while others did not. In response, NGT had requested a more detailed analysis of the compounds.

One Car Flame Retardant TCEP Deemed Carcinogenic: ICMR to NGT
New Delhi: Indian Council of Medical Research (ICMR) has submitted its response to National Green Tribunal (NGT) concerning the presence of potentially carcinogenic chemicals in car interiors. The response comes in the wake of a study published in the journal Environmental Science and Technology, which found that several cars contain flame retardant chemicals considered potentially carcinogenic—specifically, Tris (1-chloro-isopropyl) phosphate (TCIPP), Tris (1,3-dichloro-2-propyl) phosphate (TDCIPP), and Tris (2-chloroethyl) phosphate (TCEP). Of these, the ICMR has recognised TCEP as a carcinogen. The ICMR's report, dated May 22, referenced several leading international agencies, including International Agency for Research on Cancer (IARC) under the World Health Organisation, United States Environmental Protection Agency (US-EPA), US National Toxicology Program (US-NTP), and European Chemicals Agency (ECHA). These organisations have published systematic reviews identifying carcinogenic chemicals to which humans may be exposed through ingestion, inhalation, or skin contact. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo ICMR stated that, according to IARC, the chemicals are classified into different groups based on the strength of evidence—human carcinogen, probable carcinogen, possible carcinogen, and unclassified. "As of today, only one of the compounds, namely TCEP, qualifies for any of these categories, specifically Group 3 (unclassified carcinogen), while the other two chemicals, namely TDCIPP and TCIPP, do not appear on the list. In addition to the above, it is humbly submitted that India follows the World Health Organisation-IARC on carcinogens," stated ICMR. "India follows the WHO-IARC classification on carcinogens," the ICMR stated in its submission. Additionally, ICMR offered to conduct a systematic review of existing scientific literature on the carcinogenic potential of these compounds if the NGT requires it. While the council has the laboratory expertise and equipment to test biological samples such as blood for traces of these chemicals, it clarified that it does not have the mandate or technical capacity to analyse environmental samples like air from car interiors. "Detection of TCIPP, TDCIPP, and their metabolites in biological samples can be carried out, especially for individuals regularly exposed to enclosed car environments," ICMR noted.
