The acute dermal toxicity of resorcinol was studied in male albino rabbits Koppers Company, Signs of intoxication included salivation, tremors, and convulsions, and treated pores and skin areas showed slight erythema and excessive dryness. Mean information for three donors and sixteen replicates point out a plateau in receptor fluid concentration between 24 and 48 h, as reflected by cumulative absorption values of 1. A steady-state permeability coefficient. For male albino rats strain not given;.
The elimination was biphasic, with half-lives of 18—21 min and eight. The 14 C activity was rapidly distributed in main tissues such as muscles, kidneys, and liver, with out indication of bioaccumulation Merker et al. Any new info being supplied in the course of the OECD assessment might be provided to the IPCS in order that an addendum could be ready for consideration.
Furthermore, continual research with fish and Daphnia have been carried out. For the toxicity to aquatic vegetation, no guideline research is on the market. However, considering the obtainable studies for toxicity to aquatic vegetation, the NOEC for algae could be assumed to be larger than that for Daphnia magna. Exposure to resorcinol by way of peeling brokers presents an acute publicity scenario the place the individual is exposed to a excessive concentration 7. Acute results have been described underneath these conditions.
Thyroid glands from all surviving F 0 mother and father have been examined microscopically, and mind measurements had been performed on all exposed F 1 pups and people F 1 pups chosen for behavioural testing. There were no important sex differences. In females, a larger proportion was excreted as sulfate conjugate, whereas males excreted a better proportion of a diconjugate both sulfate and glucuronide groups. From these information, the authors concluded that male rats have a higher capability for glucuronidation than females.
The third examine, performed in , included of lively workers. In subjects men, 13 girls with a mean age of 37 years, both laboratory and other tests, including medical examination, were carried out; no irregular thyroid glands or adjustments in T four values were found in any of the topics in comparison with normal values Bauer, The above knowledge are restricted due to small study sizes, lack of comparability groups, lacking present and historical management data, and lacking info regarding potential exposure categories. In a research in a plant producing resorcinol by sulfonation of benzene — and also producing beta -resorcylic acid, resorcinol—formaldehyde resins, sulfites, and sulfates — staff were exposed primarily to resorcinol, but the exposure to other agents was not measured for exposure ranges, see part 6. In this plant, three cross-sectional studies have been carried out between and Flickinger, In , medical examinations, chest X-rays, pulmonary perform, haematology, and medical chemistry were carried out with of individuals actively employed at a manufacturing plant in Pennsylvania, USA. In addition, male rats have larger circulating ranges of TSH than females.
There had been no published animal studies displaying thyroidal effects with a dose—response relationship that might be used for a tolerable intake. In the frame of a full life cycle toxicity check OECD TG , Lima observed no antagonistic effects after 48 h of publicity at the highest focus tested, 0. Furthermore, Cronin et al. The fish and pond snails have been positioned directly into the aquaria, whereas the remaining 5 species have been segregated in numerous baskets and suspended within the aquaria. The solely investigation into this finish-level is that from the dose range-finding study reported in sections eight.

In both species, there have been no opposed effects on ultimate mean body weights, haematology, or clinical chemistry parameters, and no chemical-related gross or microscopic lesions were noticed. In one other research, rats had been uncovered to 0 or 0. No thyroid hormone measurements have been carried out.

• Fifty per cent of survivors were sacrificed 1 week later, and blood and urine samples were taken.





• In both species, there were no opposed effects on final mean physique weights, haematology, or medical chemistry parameters, and no chemical-associated gross or microscopic lesions were observed.





• In high-dose teams, a lower in body weight and decreased survival were famous.





• Five of 3.

Determination of resorcinol conjugates in the h urine samples after 14 days of steady product remedy confirmed that a maximal 23 mg 2. Assuming a physique weight of 64 kg IPCS, gives an exposure estimate of zero. In a report based mostly on client research knowledge Gans, , beneath cheap maximum-use conditions i.
Although thyroid results are a major end-level in each human case-research and animal studies, there is a lack of consistency within the results in the animal research. Resorcinol brought on no antagonistic results in several replica and developmental toxicity studies in rats and rabbits. Resorcinol is not thought-about to be genotoxic.

There isn't any guideline research on toxicity for aquatic crops obtainable. As only one focus was tested, the study cannot be used within the danger evaluation. There are several research obtainable on acute toxicity to completely different fish species.

There are variations in thyroid physiology between people and animals. The weight of proof means that rodents are extra delicate to thyroid effects than humans.

Other pores and skin effects were hyperplasia, hyperkeratosis, irritation, and sebaceous gland hyperplasia, whereas there have been no systemic treatment-associated lesions. With resorcinol, a number of initiation—promotion studies with hamsters Maruyama et al. Female Syrian golden hamsters 10—20 per group were handled with two subcutaneous injections of. In a examine carried out by Hasegawa et al.
The results had been extra pronounced at 72 h. The irritation index was given as four. However, owing to lacking correlating histopathological changes within the three ranges of the mind examined and within the absence of a dose—response relationship, other indicators of developmental delay, or different changes in CNS operate, these effects were not considered as conclusive evidence of a change in CNS operate. In the subsequent two-era reproductive toxicity examine RTF, , these end-points were not investigated. No resorcinol-related effects on F zero and F 1 pup survival or the final physical situation of the pups in the course of the pre-weaning period had been observed.
Apart from one positive single case-study Vilaplana et al. In these circumstances, the tested focus of resorcinol was 0. The data are summarized in Table 8. Data concerning the different job classes weren't offered.
