“…Crotamiton is a scabicide and antipruritic agent that has frequently been detected in sewage effluent in Japan because of its stable nature and wide consumption [27][28][29]. The effect of coexisting matter from the wastewater matrix on inhibiting crotamiton degradation was evaluated.…”

Abstract:Reverse osmosis (RO) concentrate from wastewater reuse facilities contains concentrated emerging pollutants, such as pharmaceuticals. In this research, a paper-like composite sheet consisting of titanium dioxide (TiO 2 ) and zeolite was synthesized, and removal of the antipruritic agent crotamiton from RO concentrate was studied using the TiO 2 /zeolite composite sheet. The RO concentrate was obtained from a pilot-scale municipal secondary effluent reclamation plant. Effective immobilization of the two powders in the sheet made it easy to handle and to separate the photocatalyst and adsorbent from purified water. The TiO 2 /zeolite composite sheet showed excellent performance for crotamiton adsorption without obvious inhibition by other components in the RO concentrate. With ultraviolet irradiation, crotamiton was simultaneously removed through adsorption and photocatalysis. The photocatalytic decomposition of crotamiton in the RO concentrate was significantly inhibited by the water matrix at high initial crotamiton concentrations, whereas rapid decomposition was achieved at low initial crotamiton concentrations. The major degradation intermediates were also adsorbed by the composite sheet. This result provides a promising method of mitigating secondary pollution caused by the harmful intermediates produced during advanced oxidation processes. The cyclic use of the HSZ-385/P25 composite sheet indicated the feasibility of continuously removing crotamiton from RO concentrate.

“…However, knowledge of if and how they transfer into the terrestrial food web is still scarce. Many polar emerging contaminants have a high potential to pass through treatment processes commonly used for landfill leachates or in WWTPs and can thus be detected in effluents and the environment (Nakada et al 2010). Thus, more knowledge of environment–food web transfer of such compounds is important.…”

Emerging contaminants in wastewater and sewage sludge spread on agricultural soil can be transferred to the human food web directly by uptake into food crops or indirectly following uptake into forage crops. This study determined uptake and translocation of the organophosphates tris(1-chloro-2-propyl) phosphate (TCPP) (log Kow 2.59), triethyl-chloro-phosphate (TCEP) (log Kow 1.44), tributyl phosphate (TBP) (log Kow 4.0), the insect repellent N,N-diethyl toluamide (DEET) (log Kow 2.18) and the plasticiser N-butyl benzenesulfonamide (NBBS) (log Kow 2.31) in barley, wheat, oilseed rape, meadow fescue and four cultivars of carrot. All species were grown in pots of agricultural soil, freshly amended contaminants in the range of 0.6–1.0 mg/kg dry weight, in the greenhouse. The bioconcentration factors for root (RCF), leaf (LCF) and seed (SCF) were calculated as plant concentration in root, leaf or seed over measured initial soil concentration, both in dry weight. The chlorinated flame retardants (TCEP and TCPP) displayed the highest bioconcentration factors for leaf and seed but did not show the same pattern for all crop species tested. For TCEP, which has been phased out due to toxicity but is still found in sewage sludge and wastewater, LCF was 3.9 in meadow fescue and 42.3 in carrot. For TCPP, which has replaced TCEP in many products and also occurs in higher residual levels in sewage sludge and wastewater, LCF was high for meadow fescue and carrot (25.9 and 17.5, respectively). For the four cultivars of carrot tested, the RCF range for TCPP and TCEP was 10–20 and 1.7–4.6, respectively. TCPP was detected in all three types of seeds tested (SCF, 0.015–0.110). Despite that DEET and NBBS have log Kow in same range as TCPP and TCEP, generally lower bioconcentration factors were measured. Based on the high translocation of TCPP and TCEP to leaves, especially TCPP, into meadow fescue (a forage crop for livestock animals), ongoing risk assessments should be conducted to investigate the potential effects of these compounds in the food web.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-012-1363-5) contains supplementary material, which is available to authorized users.

“…Under wet weather conditions, the pollution bound to particulate matter in sewers constitutes a major source of surface water pollution (Gromaire et al 2001, Chebbo andGromaire 2004). Depending on their hydrophobicity, pharmaceutical substances, such as hydrophobic antibiotics (Thomas et al 2007) or carmabazepine, an anti-epileptic drug, (Miao et al 2005) and related substances (e.g., antibacterial triclosan (Nakada et al 2010)), discharged from households and hospitals are transported by particles through sewers. Most high priority substances, as defined by the European Water Framework Directive, appear to be transported in the particulate phase (Zgheib et al 2011).…”

International audiencePollutant quantification offers a wide range of applications in the field of water resources. With respect to sewage, a key issue is sample representativeness, as samples are often collected under technically challenging conditions. A new series of experimental measurements were conducted in actual sewers in order to investigate the influence of the major factors affecting sampling. Such factors include water velocity, sampling velocity, sampling tube location and orientation of the sampling point relative to the flow direction. Results show that the influence of these factors remains within 5% of the mass of the total suspended solids concentrations, meaning that in most practical applications, this influence may be neglected
