Incorporating variations in pesticide catabolic activity into a GIS-based groundwater risk assessment

Risk assessment of exposure to volatile organic compounds in groundwater in Taiwan

“…Accurate risk assessment and ongoing risk management thus become important factors in civic programs to minimise potential threats to the public (Posen et al, 2006). Examples of relevant risk-assessment studies in the literature include: (i) estimation of the cancer risk from inhalation and dermal absorption of chloroform when showering in Taiwan (Kuo et al, 1998); (ii) estimation of the cancer risk from trihalomethanes in drinking water and inhalation exposure to chloroform (Wang et al, 2007); and (iii) estimation of the risks from exposure to trichlorethylene (TCE) and perchloroethylene (PCE) in contaminated groundwater in Taiwan (Chen and Ma, 2006).…”

Influence of Agricultural Irrigation Activity on the Potential Risk of Groundwater Pollution: A Study with Drastic Method in a Semi-Arid Agricultural Region of China

“…It is also one of the most important factors determining the groundwater pollution area and the pollutant migration rate. For example, the presence of fine particles and organic microorganisms in the soil layer can reduce its intrinsic permeability, increase the soil catabolic activity, and delay or prevent the migration of pollutants via physicochemical processes [40][41][42]. The data for S were for 2017, and the corresponding ratings are shown in Table 1 and Figure 2.…”

Ubiquity of microbial capacity to degrade metaldehyde in dissimilar agricultural, allotment and garden soils

“…pesticides) presence/augmentation is well documented for a range of compound classes, including: several semi-volatile hydrocarbon pollutants (Kelsey and Alexander 1997;Reid et al, 2002;Springael and Top, 2004;Hickman et al, 2008), pesticides (Duah-Yentumi and Johnson, 1986;Reid et al, 2005;Bending et al, 2006;Posen et al, 2006;Trinh et al, 2012;Reid et al, 2013) and antibiotics (Islas-spinosa et al, 2012;Bennet et al, 2017). These studies confirm the capacity of microbial communities to respond to organic compound input by becoming more catabolically competent (Reid et al, 2005;Bending et al, 2006;Posen et al, 2006;Reid et al, 2013). For example, Reid et al (2005) reported soil microbial communities, of initially low catabolic competence, to degrade the herbicide isoproturon, (mineralisation C. 5 %) to increase in their competence following the incubation of soil with a low (0.05 μg kg -1 ) application of the herbicide (mineralisation increased to C. 40 %).…”
