Like the gradient study . From the above results, IARC classified it in Group 2B since evidence for carcinogenicity due to styrene exposure was limited in both humans and experimental animals (IARC 82 (2002)). The International Agency for Research on Cancer (IARC) has classified styrene as a group 2B carcinogen (possibly carcinogenic to humans). Monograph evaluations are assessments of the strength of the published scientific . Rather than "reasonably anticipated," IARC says styrene is "possibly carcinogenic to humans" — the same classification they give to pickles and the coffee I like to enjoy in a foam cup. 5.1 Exposure data This designation is applied when there is limited evidence of carcinogenicity in humans as well as sufficient evidence of carcinogenicity in experimental animals. The Styrene Information and Research Center does not agree with the The agents in this list have been classified in group 2A (probable carcinogens) by the International Agency for Research on Cancer (IARC).

It is also noted that the possible mechanism of formation of metabolite styrene 7,8-oxide in mice is not likely to operate in humans. Cox regression analyses estimated rate ratios (RRs) and 95% CIs by quartile of cumulative exposure to . Furthermore, styrene is a possible human carcinogen as determined by the International Agency for Research on Cancer (IARC) (Kogevinas et al., 2018). Since that time, new data have become available, and these have been incorporated into the monograph and taken into consideration in the present evaluation. met at the International Agency for Research on Cancer (IARC) in Lyon, France, to finalise their evaluation of the carcinogenicity of quinoline, styrene, and styrene-7,8-oxide. 2 The IARC Monographs identify the preventable causes of human cancer. The term "agent" encompasses both substances and exposure circumstances that pose a risk. In 1988, the International Agency for Research on Cancer (IARC) initiated a study of workers in the reinforced plastics industry in Denmark, Finland, Italy (two centres), Norway, Sweden and the UK (in the UK, two centres) to investigate associations between the risk of tumours of the lymphatic and haematopoietic systems and exposure to styrene. IARC has based this classification on the increased cases of cancer observed in a few cases in which rats and mice were given styrene by Styrene oxide is a reactive metabolite of styrene and shows positive carcinogenic results in oral exposure bioassays. classification is not based on new health data relating to either humans or animals, but on a change in the IARC classification system. According to the court, "as plaintiff points out, there is no finding of sufficient evidence that styrene is a carcinogen for either animals or human[s] in IARC's 2002 monograph."

The toxicology of styrene was reviewed by the Commission in 1987 (Henschler 1987). 2008. IARC's 2018 decision to reclassify styrene as a Group 2A "probable" carcinogen was due, in part, to changes that IARC has made since its 2002 assessment of styrene to the technical guidelines IARC uses to assess data. "Recently published studies tracing 50,000 workers exposed to high occupational . This classification is not based on evidence that styrene may be carcinogenic, This classification is not based on evidence that styrene may be carcinogenic, but rather on a revised definition for Group 2B, and Overall Evaluations of Carcinogenicity to Humans, as evaluated in IARC Monographs Volumes 1-99 (a total of 935 agents, mixtures and exposures). Styrene has been listed by the National Toxicology Program (NTP) as reasonably expected to be a human carcinogen.The International Agency for Research on Cancer (IARC) has listed styrene as a group 2B carcinogen (possibly carcinogenic to humans). In the present English translation of the supplement from 1998, the genotoxic and carcinogenic potential of styrene is evaluated within the framework of the new system for classification of carcinogenic substances (1998 MAK documentation: see "Changes in the Classification of Carcinogenic Chemicals in the Work . This new classification is not based on new health data relating to either humans or animals, but on a change in the IARC classification system. In general, IARC attributes the carcinogenic effect of styrene to genotoxic and carcinogenic metabolite of styrene - styrene 7,8-oxide. The Styrene Information and Research Center does not agree with the IARC definition and list of compounds The Styrene Information and Research Center does not agree with the reclassification and has published the following statement.

REGULATORY INFORMATION Classification and Labeling of Commonly Used Dangerous Chemical Substances. deliberations on styrene carcinogenicity and agree with the NTP in its classification of styrene. Styrene. These include chemicals, physical and biological agents, pharmaceuticals, complex mixtures, occupational exposures, and other exposures of everyday life (e.g. Methods Employees were followed from 1943 through 2009 to determine mortality outcomes. IARC (International Agency for Research on Cancer). findings, styrene was subsequently classified as 'possibly carcinogenic to humans' (group 2B) by the International Agency for Research on cancer2 and as 'reasonably anticipated to be a human carcin-ogen' in the US Report on Carcinogens.13 Subsequent to those evaluations, further anal-yses of several cohorts exposed to styrene have This volume of the IARC Monographs provides evaluations of the carcinogenicity of quinoline, styrene, and styrene-7,8-oxide. Nov 2, 2012. This volume provides evaluations of the carcinogenicity of styrene, styrene-7,8-oxide, and quinoline. IARC classifications are based on hazard assessments and not risk assessments.

Compounds or physical factors assessed by IARC (International Agency for Research on Cancer) are classified in four groups based on the existing scientific evidence for carcinogenicity.. Group 1: "Carcinogenic to humans" There is enough evidence to conclude that it can cause cancer in humans. Styrene oxide has been detected in workers exposed to styrene. Some substance identifiers may have been claimed . Styrene, also known as vinylbenzene, is a clear, colorless to yellow, oily liquid that has a sweet odor at low concentrations.It is used in the manufacture of plastics, paints, synthetic rubbers, protective coatings and resins. New Window. The Court noted that vinyl acetate's 1995 IARC classification was based on inadequate evidence of carcinogenicity in humans and limited evidence of carcinogenicity in experimental animals, while styrene's 2002 IARC classification was based on limited evidence of carcinogenicity in both humans and experimental animals. The exposure circumstance entails exposures that are possibly carcinogenic to humans. Description of first aid measures Inhalation Move person to fresh air immediately. Quinoline also occurs in the processing of petroleum and shale oil, and is found in groundwater and soil at sites contaminated by coal tar and creosote. As reliable information is provided by studies, classification and number of CMRs may change.
