Some formed during natural processes. may be substituted chlorine atoms, nitrated, methylated or alkylated. both catechols harmful ecotoxins. Toxic action these stems from unspecified toxicity to hydrophob ocity radicals reactive oxygen species. re veal peroxidative capacity, they hematotoxic hepatotoxic, provoke mutagenesis carcinogenesis toward humans living organisms.
