“…microbial biomass) density is an important factor affecting the outcome of chemical biodegradation tests (Thouand et al 1995;Godhead et al 2014) and in particular, inconsistent 70 test results may reflect differences in inoculum quality because of temporal and spatial variability of microbial community density and diversity within environmental compartments (Courtes et al 1995;Mezzanotte et al 2005).…”

“…For these reasons, use of biofilms in biodegradation tests could provide a means of reducing the chance of common test failures described by Thouand et al (1995) and Godhead et al (2014), by eliminating the 110 'biodegradation lottery' associated with low biomass in regulatory tests (Kowalczyk et al, 2014). However, to date, investigations of the potential to use biofilm inoculum in regulatory tests has centered on laboratory generated inoculum.…”

“…Despite MPTs prohibited use in agriculture in 2004 in Thailand, its metabolite PNP was recently detected in 2009 among farmers and children in > 90 % in all samples analyzed and attributed to exposure from continued MPT use [10]. Furthermore PNP is a usable model chemical pollutant in the elaboration of biodegradability tests due to its erratic biodegradability [11,12]. More recently water remediation by biological systems has attracted worldwide attention to decontaminate nitro-aromatics polluted sources [13].…”

We report for the first time on the elaboration of a remarkable sensitivity type C/p-NiTSPc carbon fiber microelectrode (CFME) for p-nitrophenol (PNP) pollutant. We observed the best performances using square wave voltammetry (SWV) technique in the place of differential pulse voltammetry (DPV). Also the combination of p-NiTSPc optimized cycles of electrodeposition and accumulation time, helped us to increase remarkably the sensor slope (320 times) and the limit of detection (LOD) (1000 times), with a final LOD of 0.1 mg/L, the current regulatory limit for drinkable waters. Furthermore the recoveries of the standards added are close to 100 % indicating that the method has some suitability. The proposed voltammetric procedure might be applied for organophosphorus pesticides and their by-products with a remarkable sensing in natural polluted waters.

“…The biases of the poor comparability for ready biodegradation resulting from different properties of activated sludge and experimental conditions in different laboratory can be avoided. Many reports had indicated that properties of activated sludge (microbial activities, species of the microbial inoculums, et al) might result in great variation of ready biodegradation (Goodhead et al 2014;Kowalczyk et al 2015;Thouand et al 1995). Our study first obtained a number of experimental data under the same experimental conditions to demonstrate the effects of molecular descriptors on ready biodegradation.…”

Ready biodegradation is the primary biodegradability of a compound, which is used for discriminating whether a compound could be rapidly and readily biodegraded in the natural ecosystems in a short period and has been applied extensively in the environmental risk assessment of many chemicals. In this study, the effects of 24 molecular properties (including 2 physicochemical parameters, 10 geometrical parameters, 6 topological parameters, and 6 electronic parameters) on the ready biodegradation of 24 kinds of synthetic aromatic compounds were investigated using the OECD 301B CO2 Evolution test. The relationship between molecular properties and ready biodegradation of these aromatic compounds varied with molecular properties. A significant inverse correlation was found for the topological parameter TD, five geometrical parameters (Rad, CAA, CMA, CSEV, and N c), and the physicochemical parameter K ow, and a positive correlation for two topological parameters TC and TVC, whereas no significant correlation was observed for any of the electronic parameters. Based on the correlations between molecular properties and ready biodegradation of these aromatic compounds, the importance of molecular properties was demonstrated as follows: geometrical properties > topological properties > physicochemical properties > electronic properties. Our study first demonstrated the effects of molecular properties on ready biodegradation by a number of experiment data under the same experimental conditions, which should be taken into account to better guide the ready biodegradation tests and understand the mechanisms of the ready biodegradation of aromatic compounds.
