cresols poisoning
the form of poisoning depends on the route of entry and the dose. There may be local corrosion, or cardiac depression, or liver damage with signs of jaundice, weakness, coma and death.

Phenol and cresols were biodegraded by 80%, but the concentration of dimethylphenols practically did not change.
Phenol, cresols, formaldehyde and other components of resin binders and acids and alkalines used as catalysts, which would be present in many waste foundry sands (including green sand), would probably result in the waste being treated as special waste.
Analysis of structure/functional property relationships for novolak resins containing cresols has only been recently reported (13- 15).
Dimers of the meta or para-cresols with the 2,3,5 trimethyl phenol with a small amount of dimers of the meta or para cresols or cross products were found under these conditions (18).
The novolacs were prepared in the usual manner by condensation of halogenophenols or cresols with formaldehyde in the presence of an acid catalyst (6).
We had found convenient development conditions for a three-component resist formulation (halogenophenol novolac/cresol novolac/melamine crosslinker Cymel 303) containing cresol novolac additionally.
Reportlinker Adds Production and Market of Cresols in China
Cresols as key fine chemical intermediates play an important role in producing antioxidant, Vitamin E, pesticides, flavor and so on.
What is the situation of cresols production in China?
The fact that this value was higher than the values for p-cresol, 5-methylresorcinol, resorcinol and o-cresol indicates that phenol was more readily oxidized by the studied activated sludge than cresols or resorcinols.
The obtained results showed that phenol, hydroxyphenols and cresols were degraded by activated sludge faster than dimethylphenols.
