“…Other pyrethroids frequently detected were cyfluthrin (up to 23 ng/L) and permethrin (up to 125 ng/L). In another study, Chinen et al (2016) reported the concentration of detected pyrethroids at 5.1-1408 ng/g dry weight in October 2013 and 11-1210 ng/g dry weight in February 2014; this difference was attributed to the size of the storm event during the sampling time.…”

“…Diazinon and chlorpyrifos concentrations in urban stormwater runoff increased gradually throughout the storm hydrograph, with peak concentrations occurring in the last sample. Chinen et al (2016) suggested that the seasonal nature of the rainfall in Los Angeles, California creates a long dry period, and this may allow pyrethroids to be degraded. Therefore, an evaluation of the typical half-life of the various pyrethroids can reveal opportunities to reduce emissions to the receiving water by managing application times.…”

“…The runoff transferability of pyrethroid residues from concrete is not significantly affected by concrete surface conditions Jiang et al (2012) Densely populated areas in urban watersheds with a high factor of impervious surfaces produce the highest amount of synthetic pyrethroids (SPs) runoff. Chinen et al (2016) Catchment with a significant soil moisture deficit generates low runoff volumes. Revitt et al (2002) gradually desorbed in the course of a certain period after the pesticide applications.…”

“…As a result of the undergoing rapid urban expansion, stormwater runoff in highly urbanized watersheds tend to possess a substantial concentration of OCPs and poses a potential threat to the local urban water systems . Similarly, Chinen et al (2016) reported that highly impervious urban areas can produce the largest amounts of synthetic pyrethroids (SPs) runoff. Hence, the focus should be made on the residential and commercial land uses which were identified as the highest level of dischargers.…”

Abstract:The growth and spread of impervious surfaces within urbanizing catchment areas pose signiificant threats to the quality of natural and built-up environments. Impervious surfaces prevent water infiltration into the soil, resulting in increased runoff generation. The Erbil Sub-basin was selected because the impervious cover is increasing rapidly and is affecting the hydrological condition of the watershed. The overall aim of this study is to examine the impact of urban growth and other changes in land use on runoff response during the study period of 1984 to 2014. The study describes long-term hydrologic responses within the rapidly developing catchment area of Erbil city, in the Kurdistan Region of Iraq. Data from six rainfall stations in and around the Erbil Sub-basin were used. A Digital Elevation Model (DEM) was also used to extract the distribution of the drainage network. Historical levels of urban growth and the corresponding impervious areas, as well as land use/land cover changes were mapped from 1984 to 2014 using a temporal satellite image (Landsat) to determine land use/land cover changes. Land use/land cover was combined with a hydrological model (SCS-CN) to estimate the volume of runoff from the watershed. The study indicates that the urbanization of the watershed has increased the impervious land cover by 71% for the period from 1984 to 2004 and by 51% from 2004 to 2014. The volume of runoff was 85% higher in 2014 as compared to 1984 due to the increase in the impervious surface area; this is attributed to urban growth. The study also points out that the slope of the watershed in the Erbil sub-basin should be taken into account in surface runoff estimation as the upstream part of the watershed has a high gradient and the land is almost barren with very little vegetation cover; this causes an increase in the velocity of the flow and increases the risk of flooding in Erbil city.

BACKGROUND: Pest management professionals will require a diverse, adaptive abatement toolbox to combat advanced challenges from disease vector and nuisance insect populations. Designed for post-application longevity, insecticidal paints offer extended residual effects on targeted insect pest populations; a measured understanding of active ingredient bioavailability over time is valuable to fully assess treatment efficacy and potential environmental risks. This study was initiated because a nuisance net-spinning caddisfly, Smicridea fasciatella, is lowering the quality of life for riverfront residents at the type locality. RESULTS:We tested the efficacy and potential mobility of a transfluthrin-based paint (a.i. 0.50%), comparing the impacts of UV exposure and substrate texture over time. Direct UV exposure decreased efficacy (⊎ ± S.E. = 0.008 ± 0.001, P < 0.001) and a coarse texture maintained greater efficacy (⊎ ± S.E. = −3.7 ± 1.3, P = 0.004) over time. Notably, the coarse texture + indirect UV treatment maintained 100% mortality after 240 days. UV exposure and substrate texture did not have a significant impact on leachate concentrations over time, and successive immersion tests indicated a two-phase emission pattern. Bioaccumulation increased with time on the cuticle of dead adult S. fasciatella; after 24 h of direct exposure the concentration of transfluthrin was 25.3 ± 0.9 ng/caddisfly with a maximum concentration of 345 ng/caddisfly after 7 days. CONCLUSION: Our predictions were validated with measured, time-dependent impacts on efficacy, leachability, and bioaccumulation. Because of the mobility of active ingredient in the environment, insecticidal paints merit low-impact protocols to improve public health outcomes and environmental safety.
