In general, the h LC 50 values for resorcinol have been in the range between In move-by way of checks and analytical monitoring, DeGraeve et al. As talked about in section 9. Complete therapeutic was famous after about 1 week of absence from work. However, with growing resorcinol concentrations, there was additionally an increase in the variety of persons who examined positive. Resorcinol was also tested in hairdressers, who could have been in contact with resorcinol-containing hair dyes.


Koppers Company studied attainable pores and skin irritating effects of flaked or industrial resorcinol in male albino rabbits mg underneath occlusive conditions over 24 h, scoring after 24 and seventy two h. In one research performed with male Syrian golden hamsters, which targeted solely on results on the forestomach, pyloric region, and urinary bladder, the animals had been dosed with 0 or 0.

Determination of resorcinol conjugates in the h urine samples after 14 days of continuous product therapy confirmed that a maximal 23 mg 2. Assuming a physique weight of sixty four kg IPCS, gives an exposure estimate of zero. In a report primarily based on client research information Gans, , under cheap maximum-use situations i.
In both species, there have been no adverse results on final imply body weights, haematology, or medical chemistry parameters, and no chemical-associated gross or microscopic lesions have been observed. In another research, rats have been uncovered to zero or 0. No thyroid hormone measurements have been carried out.
The elimination was biphasic, with half-lives of 18—21 min and eight. The 14 C activity was quickly distributed in main tissues such as muscular tissues, kidneys, and liver, with out indication of bioaccumulation Merker et al. Any new info being provided in the course of the OECD assessment might be offered to the IPCS so that an addendum may be prepared for consideration.


The third examine, performed in , included of energetic employees. In subjects men, 13 women with a mean age of 37 years, each laboratory and different exams, together with medical examination, had been done; no irregular thyroid glands or adjustments in T 4 values have been found in any of the subjects when compared with normal values Bauer, The above knowledge are restricted as a result of small examine sizes, lack of comparability groups, lacking current and historical management data, and lacking information regarding potential exposure classes. In a research in a plant producing resorcinol by sulfonation of benzene — and in addition producing beta -resorcylic acid, resorcinol—formaldehyde resins, sulfites, and sulfates — staff have been exposed primarily to resorcinol, but the publicity to different brokers was not measured for exposure ranges, see part 6. In this plant, three cross-sectional studies had been carried out between and Flickinger, In , medical examinations, chest X-rays, pulmonary perform, haematology, and medical chemistry have been carried out with of individuals actively employed at a production plant in Pennsylvania, USA. In addition, male rats have larger circulating ranges of TSH than females.


Resorcinol is understood to type covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported each in animal research and in case-reports in people. However, there are species variations in the susceptibility to goitrogens.
