to substantial occupational exposure The ITC cited the National Institute for Occupational Safety and Healths (NIOSH) estimates that roughly 2 million workers are exposed to cresols. The ITC also was concerned that cresols are used in many consumer products and that these uses couldresult in a large consumer and general population exposure. C. Non-occupational chloracne has resulted from industrial accidents, contaminated industrial waste, and contaminated food products. A widely publicized example was the extensive environmental contamination with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) (Fig. 1), which occurred on J , at the ICMESA chemical plant near Seveso, Italy Cited by:

Structure and production. In its chemical structure, a molecule of cresol has a methyl group substituted onto the ring of phenol.
There are three forms of cresol: ortho-cresol (o-cresol), meta-cresol (m-cresol), and para-cresol (p-cresol).These forms occur separately or as a mixture, which can also be called cresol or more specifically, tricresol.
 About half of the. o-Cresol is a minor urinary metabolite of toluene, a widely used chemical with neurotoxicological properties.(PMID: ). o-Cresol is used commercially as a re may occur by inhalation, by cutaneous adsorption or by oral ingestion. o-Cresol denature and precipitate cellular proteins and thus may rapidly cause poisoning.

The concentration of toluene in the air of the working place was determined using stationary air sampling and gas chromatography. To determine the levels of toluene in blood as well as the concentrations of o-cresol, hippuric acid, and phenol in urine, Cited by: Permissible Exposure Limits / OSHA Annotated Table Z-1; Note: This table only includes occupational exposure limits (OELs) for substances listed in the OSHA Z-1 Table.
OELs for hundreds of additional substances have been adopted by Cal/OSHA, NIOSH, and organizations periodically make revisions to their OELs and so they should be consulted. Andersson R, Carlsson A, Nordqvist MB, Sollenberg J.

Toluene is a volatile organic solvent used by most industries and. household items such as. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here.
Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties.
Other pertinent literature is also presented, but is described in less. Cresols are a widely occurring natural and manufactured group of chemicals.
In their pure form, they are colorless solids and may be liquids if they are mixtures. Cresols smell like medicine. There are three forms of cresols that differ slightly in their chemical structure: ortho-cresol (o-cresol), meta-cresol (m-cresol, and para-cresol (p-cresol).

Description and Properties, - A colorless or straw-colored refractive liquid having a phenol-like odor and turning yellowish-brown on prolonged exposure to light. Sometimes erroneously called crecylic acid. Cresol is methyl phenol, the three isomeric forms being known chemically as ortho- meta- and paracresol.
the potential for occupational and consumer exposure and the lack of chronic toxicity data. Male F/N rats and female B6C3F1 mice were exposed to a mix-ture of m‑ and p‑cresol (m‑/p‑cresol) (greater than % pure) in feed for 2 years.
Genetic toxicology studies were conducted in Salmonella typhimurium, Escherichia. p-Cresol >95 4. First-aid measures General Advice Show this safety data sheet to the doctor in attendance.

Inhalation. At an exposure level of 9 mg o-cresol/m3, 6 hours/ day, 5 days/week for 2 months and then for 4 hours/day, 5 days/week for 2 subsequent months, exposed guinea pigs had unspecified changes 1n.
Cresol (C 7 H 8 O), any of the three methylphenols with the same molecular formula but having different structures: ortho- (o-) cresol, meta- (m-) cresol, and para- (p-) cresol. The cresols are obtained from coal tar or petroleum, usually as a mixture of the three stereoisomers (molecules with the same number and type of atoms but with unique atom arrangements).
transitional cell carcinoma of the bladder following chronic occupational exposure to cresol and creosote. Wodyka (, as cited in U.S. EPA., ) described a squamous cell carcinoma of the vocal cords in a petroleum refinery worker with a long history of exposure to cresol, dichlorooctane, and chromic Size: KB.
Clinical relevance Cresol and phenol are formed as metabolites in the body after exposure to toluene and benzene respectively. Toluene and benzene are toxic substances which are used on an industrial scale e.g. as solvents and fuel additives. In 62 male rotogravure printers, the time-weighted average (TWA) toluene exposure during one workweek ranged from 8 to mg/m3 (median 96).
Post-shift urinary excretion of hippuric acid showed a poor correlation with the air toluene concentration. Level of o-cresol excretion ranged from to mmol/mol creatinine and was associated with the Cited by: ortho-Cresol, also 2-methylphenol, is an organic compound with the formula CH 3 C 6 H 4 (OH).
It is a colourless solid that is widely used intermediate in the production of other chemicals. It is a derivative of phenol and is an isomer of p-cresol and ein Reference: Occupational exposure to 1-bromopropane occurs primarily from its use in spray adhesives, dry cleaning (including use as a spot cleaner), and degreasing (vapor, cold, and aerosol cleaning).
Workers are expected to be the most highly exposed population. Occupational exposure to 1-bromopropane may also occur through skin contact, although. Para-occupational Asbestos Exposure — The Subtle Killer The most common way through which people have been exposed to hazardous levels of asbestos dust is occupational exposure.
Prior to regulation that was enacted in the early s, asbestos and asbestos-laden materials were routinely used throughout a variety of industries for a number of. In this study, health risks of occupational exposure to eight hazardous VOCs (phenol, p-cresol, o/m-cresol, benzene, toluene, ethylbenzene, o-xylene, and m/p-xylene) that are most likely to be emitted from swine buildings were assessed using Monte Carlo simulation.
The purpose of the study was to calculate emission rates and to quantify cancer Cited by: 6.Dietary Exposure Since m-cresol and xylenol are applied only to the bases of fruit and nut trees, no residues are expected to remain in food or feed commodities.
The Agency is requesting the registrant seek an exemption from tolerance (enforceable residue limit). Occupational and Residential Exposure.Seven men came under observation who had been employed between 18 months and three years in a motor-car factory manipulating a mixture of cresol, formol, ammonia and asbestos.
All complained of headache, especially on commencing work, and nausea associated with vomiting. Examination disclosed low blood pressures and tremor.
While the condition was mild, it was Author: M. Duvoir, R. Hazemann, H. Desoille, P. Fallot.
