Animals have been maintained for several months with periodic sacrifices Flickinger, The animals were then examined weekly for 10 further weeks. Sacrificed animals confirmed brown-dyed abdomen walls and filling of stomach and small intestine with a dark-brown to orange substance. These findings were not famous in survivors.
The tolerable intake of 0. It is therefore potential that these neurological effects are because of the acute effect of the gavage administration. CNS results in humans and animals have been associated with acute exposure to resorcinol.
No resorcinol-related macroscopic findings, organ weight, or adverse microscopic target organ results had been noticed in the F zero and F 1 parental animals. The F 0 and F 1 females continued to obtain the resorcinol throughout mating, gestation, and lactation and through the day of euthanasia for examine design, see Appendix 7. There had been no F 0 and F 1 parental resorcinol-associated deaths or clinical findings during the weekly detailed bodily examinations. In controls and the high-dose group, a qualitative histopathological analysis of the mind forebrain, midbrain, and hindbrain was additionally performed for the aforementioned animals RTF, There have been no adverse results regarding reproductive performance, mortality, and physique or organ weights.
Experimental data on soil sorption utilizing silty loam point out a very low potential for geoaccumulation. However, the uncovered space cm 2 was significantly in extra of the typical space of pores and skin often handled for pimples. Formulations tested in the important thing research anti-pimples cream and hair dye have in all probability changed during the last 20 or more years. Resorcinol enters the surroundings primarily throughout its usage in client products hair dyes and pharmaceuticals. In addition, localized high concentrations can seem in coal conversion wastewater or in wastewater in regions with oil shale mining.
Furthermore, chronic studies with fish and Daphnia were performed. For the toxicity to aquatic plants, no guideline examine is on the market. However, taking into account the available studies for toxicity to aquatic vegetation, the NOEC for algae may be assumed to be higher than that for Daphnia magna. Exposure to resorcinol by means of peeling brokers presents an acute publicity state of affairs the place the particular person is exposed to a high focus 7. Acute effects have been described under these circumstances.
- No other biologically vital variations in organ weights have been noticed.
- Owing to concern about the thyroid results of resorcinol, which have been shown in human research to happen at excessive doses, this finish-level particularly has been the point of focus in a number of studies.
- Five of 3.
- British Journal of Industrial Medicine , Toxicologic Pathology , Toxicology and Applied Pharmacology , Arnott DG, Doniach I The impact of compounds allied to resorcinol upon the uptake of radioactive iodine I by the thyroid of the rat.
- There were no F zero and F 1 parental resorcinol-related deaths or clinical findings during the weekly detailed bodily examinations.
- From the scarce knowledge obtainable, using resorcinol in hair dyes 0.
- In these instances, the tested concentration of resorcinol was 0.
Koppers Company studied possible pores and skin irritating results of flaked or industrial resorcinol in male albino rabbits mg under occlusive conditions over 24 h, scoring after 24 and 72 h. In one examine performed with male Syrian golden hamsters, which focused solely on results on the forestomach, pyloric region, and urinary bladder, the animals have been dosed with 0 or zero.
Resorcinol is thought to form covalent bonds with haem Sessler et al. Effects on the thyroid gland have been reported each in animal research and in case-reviews in humans. However, there are species variations in the susceptibility to goitrogens.
Animals that died confirmed hyperaemia and distension of stomach and gut, while there were no gross lesions at necropsy in survivors Flickinger, In one other study with CFY rats. Most of the studies are of sufficient quality and acceptable for risk characterization functions.
From the scarce data obtainable, using resorcinol in hair dyes 0. The use of anti-acne cream is taken because the situation of most concern due to the chance of steady publicity.
