“…ASs degrade rapidly in aerobic terrestrial environments as a result of microbial activity (Litz et al, 1987;Schoberl et al, 1988;Knaebel et al, 1990). For LAS, half-life of 1-22 days in soil has been reported by Litz et al (1987), de Henau et al (1986b, Holt et al (1989), Waters et al (1989), andHERA (2004). It has been documented (Venhuis and Mehrvar, 2004) that LAS which makes up 0-16,000 mg/kg of the total dry weight of sewage sludge may influence microbial activity of the soils.…”

“…3). There it is observed that at pH values higher than 5.5, analysis times are shorter, but the resolution for the studied compounds is worse, specifically for the p-(sulfophenyl)butyric acids (2C 4 -, 3C 4 -, and 4C 4 -SPC). At pH values lower than 5.5 resolutions are better, but analysis time is longer.…”

“…The majority of this wastewater is treated via domestic treatment plants where LAS's biodegradation may occur, but they can be introduced as pollutants in natural ecosystems through the direct application of untreated wastewater as irrigation water and through the use of sewage sludge as a fertilizer on agricultural soils [4]. Moreover, LAS may enter the soil compartment through the use of pesticides, detergents incorporated to pesticide formulations as emulsifiers, dispersing, and spreading agents [5].…”

Determination of sulfophenyl carboxylic acids in agricultural groundwater samples by CE with ultraviolet absorption detection

An analytical method for the determination of six sulfophenyl carboxylic acids, namely (p-sulfophenyl)acetic, 2-(p-sulfophenyl)propionic, 2-(p-sulfophenyl)butyric, 3-(p-sulfophenyl)butyric, 4-(p-sulfophenyl)butyric, and 5-(p-sulfophenyl)valerianic acid, in agricultural irrigation water samples was developed. It involves an SPE procedure, an on-line preconcentration normal stacking mode and subsequent separation and determination using CE with UV detection (CE-UV). p-Sulfobenzoic acid was used as internal standard. The compounds were separated with an uncoated capillary and a 25 mM ammonium acetate/acetic acid buffer solution (pH 5.5) with 2-propanol (30% v/v) and 0.75 mM CTAB. Analyses were run at -25 kV, 25 degrees C, and 100 s of hydrodynamic injection with UV detection at 225 nm. Quantification limits found ranged between 4 and 6 ng/mL. The proposed method was validated using a recovery assay. It was satisfactorily used for the determination of these compounds in groundwater samples to track down the biodegradation of linear alkylbenzene sulfonates in an agricultural soil from the fertile plain of Granada (Spain).

“…However, short-chain alkyl-bonded reversed phases like C-8 (Marcomini and Giger 1987;Ahel and Giger 1985a;Leon et al 2000;Ceglarek et al 1999;Di Corcia et al 1991) and C-1 columns (Castles et al 1989), or long-chain C-18 phases with isocratic elution (Nakae et al 1980;Holt et al 1989), eluted the isomers of every single LAS homologue as one peak. Thus, the interpretation of the chromatograms becomes easier because of a greatly reduced number of peaks.…”

Surfactants in sludge-amended agricultural soils: a review

et al. 2008

Surfactants are included in different detergent formulations and are one of the most ubiquitous and important families of organic compounds. Although the generic term applies to a great number of products, 80% of their demand is covered by only ten types of compounds. The global surfactant market volume size is more than 18 million tons per year. Large quantities of surfactants are continuously released into the environment, where they can or cannot be degraded depending on their structure. The alkylbenzenesulphonate (LAS) is the most widely used surfactant. LAS can be degraded under aerobic conditions but is persistent in the environment under anaerobic conditions. Surfactants may enter the terrestrial environment through several routes, with the use of sewage sludge as fertiliser on agricultural land being by far the most important. High concentrations of surfactants and their degradation products may affect the biota. On the other hand, due to their amphiphilic nature, surfactants may interact both with inorganic as well as organic contaminants affecting their bioavailability.
