“…Chloroguaiacols and cathecols can be biologically methylated to anisoles and veratroles during effluent treatment or later in the environment (Häggblom et al 1988). A part of chlorinated compounds in pulp mill effluents have been found to degrade in recipient water (Remberger et al 1986;Paasivirta et al 1988). However, chlorinated guaiacols and catechols can preserve for a long time in sediments.…”

“…Typically, large molecules like lignin have been considered to be biologically inert and non-toxic to organisms (Paasivirta et al 1988;Maatela et al 1990;Pessala et al 2010). A molecule with large molecule size (> 2 kDa) is biologically inactive because they are too large to penetrate into cells.…”

“…Several workers have quantified these compounds in effluents and receiving waters [12][13][14][15][16][17] and in sediments [18][19][20]. Studies that identified chlorinated phenolics concurrently in both receiving waters and sediments include Xie et al [17], Paasivirta et al [15,18], and Owens et al [4].…”

Abstract-Chloroguaiacols are common components of bleached-kraft pulp mill effluent known to bioaccumulate in aquatic organisms and to sorb on particulate material and sediments. Ionization properties of the chloroguaiacols must be known in order to explain their sorptive behavior in aquatic systems. To obtain this information, thermodynamic acid dissociation constants (pK a ) of guaiacol (omethoxyphenol) and nine chloroguaiacols have been determined by spectrophotometric methods. These experimental pK a values have been compared with literature values, values predicted by the Hammett equation, and predictions by quantum chemical calculations using MOPAC 6.0 with AM1 and MNDO Hamiltonian operators. Experimental and predicted acidities were strongly correlated, and the correlation equations obtained have been used to calculate pK a values for those chloroguaiacols that were unavailable for experimental measurement.

“…Chlorophenols have been used as wood preservatives, fungicides, and intermediates in the production of chlorinated pesticides, and in the preparation of adhesives for more than 50 years [1]. Other sources of chlorinated phenols in the environment are the hydrolysis of phenoxyacidic herbicides [2] and the chlorination of phenol resulting from the degradation of lignin in pulp and paper mills when chlorine is used during the bleaching process [1,[3][4][5]. Chlorine treatment of drinking water can also produce chlorophenols [6].…”
