“…21 days or more) [1]. Sanz et al [133] highlighted that spiking high concentrations (e.g. 230 g/kg) of linear alkyl sulphonate, nonylphenol, and bis(2-ethylhexyl) phthalate to a laboratory-scale in-vessel compost did not have negative impact on composting efficiency and TrOC removal, nonetheless further investigation using other types of TrOCs must be performed.…”

“…Significant TrOC removal (e.g. >60%) of linear alkyl sulphonate [132,133], nonylphenol [68,[130][131][132], polycyclic aromatic hydrocarbons [129], and certain pharmaceuticals (e.g. ciprofloxacin and norfloxacin) [40] have been reported depending on composting conditions (Table 1).…”

“…Meanwhile, Das and Xia [135] found that decreasing the ratio of sludge and wood chips from 65:35 to 43:57 significantly decreased the half-life of nonylphenol, probably due to the enrichment of nonylphenol-degrading microorganisms at lower carbon to nitrogen ratio in the compost. The importance of the nutritional makeup of the compost to TrOC removal is also apparent in batch cultures of composted sludge by Sanz et al [133], which exhibited 10-20% increase in the removal of linear alkylbenzene sulphonates upon supplementation of glucose, tryptone soy broth, yeast extract, or peptone.…”

“…The mechanism of TrOC removal during composting is generally attributed to microbial degradation [68,69,133,135], although volatilisation of compounds with relatively high Henry's constant k H , (e.g. nonylphenol and polychlorinated biphenyls) has also been observed [68].…”

“…Compounds biodegradation could range from 98 to 99%. [12−14] Although for a long time biodegradation under anaerobic conditions was thought not to occur, indications of LAS anaerobic biodegradation have been recently reported [15,16] based on studies conducted in pilot and bench-scale upflow anaerobic sludge blanket reactors. Therefore, it is possible that under certain specific conditions, LAS and soap biodegrade without oxygen.…”

In this work we present a monitoring study of linear alkylbenzene sulfonates (LAS) and insoluble soap performed on Spanish sewage sludge samples. This work focuses on finding statistical relations between LAS concentrations and insoluble soap in sewage sludge samples and variables related to wastewater treatment plants such as water hardness, population and treatment type. It is worth to mention that 38 samples, collected from different Spanish regions, were studied. The statistical tool we used was Principal Component Analysis (PC), in order to reduce the number of response variables. The analysis of variance (ANOVA) test and a non-parametric test such as the Kruskal-Wallis test were also studied through the estimation of the p-value (probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true) in order to study possible relations between the concentration of both analytes and the rest of variables. We also compared LAS and insoluble soap behaviors. In addition, the results obtained for LAS (mean value) were compared with the limit value proposed by the future Directive entitled "Working Document on Sludge". According to the results, the mean obtained for soap and LAS was 26.49 g kg(-1) and 6.15 g kg(-1) respectively. It is worth noting that LAS mean was significantly higher than the limit value (2.6 g kg(-1)). In addition, LAS and soap concentrations depend largely on water hardness. However, only LAS concentration depends on treatment type.

The impact of a full-scale biosolid composting plant on the fate of a broad range of priority organic pollutants was investigated. Chemical analysis was performed at different steps of the process during two seasons. Simultaneously, the toxicological quality was assessed using estrogen α-, dioxin-, and pregnane X-receptor reporter cell lines. Mass-balance calculation highlighted the removal of easily degradable pollutants during composting. The important variations observed for each compound and for the two seasons might be explained by pollutant-fate dependency on process parameters like temperature. The final compost displayed low pregnane X activity but high estrogenic activity. The dioxin-like activity stayed constant through the process. The chemical and toxicological results highlight the importance of combining both approaches to accurately assess the compost quality. Such compilation of data on full-scale processes may be also very helpful for the environmental risk assessment of new organic waste disposal practices.
