“…Both permethrin and delta/tralomethrin storm flow concentrations were approximately 15-fold greater than low flow concentrations (based on the FWMCs), while bifenthrin storm flow concentrations were approximately 5-fold greater (note that there is greater uncertainty in FWMC estimates for pyrethroids than for the other pollutants due to a smaller sample size and a lack of sampling at turbidities in the higher range of observations ). All of the storm flow samples for permethrin and bifenthrin (generally considered to be the leading cause of pyrethroidrelated toxicity in the urban environment) exceed the non-regulatory chronic toxicity criteria developed by UC Davis, and most storm samples exceed the acute toxicity criteria as well, sometimes up to an order of magnitude in exceedance (Table 2; Brander et al, 2010;Fojut and Tjeerdema, 2011). Acute toxicity criteria were exceeded less frequently during lower flows, although all permethrin concentrations exceeded the chronic criterion value even during low flows.…”

“…Water quality criteria (WQC) have recently been developed for five pyrethroids, three OPs, and the herbicide diuron (Fojut et al 2012a, b;Palumbo et al 2012). In all cases, the WQC are lower than the US EPA benchmarks.…”

Urban pesticide use has a direct impact on surface water quality. To determine the extent of pesticide contamination, the California Department of Pesticide Regulation initiated a multi-area urban monitoring program in 2008. Water and sediment samples were collected at sites unaffected by agricultural inputs in three areas: Sacramento (SAC), San Francisco Bay (SFB), and Orange County (OC). Samples were analyzed for up to 64 pesticides or degradates. Multiple detections were common; 50 % of the water samples contained five or more pesticides. Statewide, the most frequently detected insecticides in water were bifenthrin, imidacloprid, fipronil, fipronil sulfone, fipronil desulfinyl, carbaryl, and malathion. Bifenthrin was the most common contaminant in sediment samples. Key differences by area: OC had more pesticides detected than SAC or SFB with higher concentrations of fipronil, whereas SAC had higher concentrations of bifenthrin. The most frequently detected herbicides were 2,4-D, triclopyr, dicamba, diuron, and pendimethalin. Key differences by area: OC and SFB had higher concentrations of triclopyr, whereas SAC had higher concentrations of 2,4-D and dicamba. Detection frequency, number of pesticides per sample, and pesticide concentration increased during rainstorm events. In water samples, all of the bifenthrin, malathion, fipronil, permethrin, and λ-cyhalothrin detections, and most of the fipronil sulfone and cyfluthrin detections were above their lowest US EPA aquatic benchmark. Diuron was the only herbicide that was detected above its lowest benchmark. Based on the number of pesticides and exceedances of aquatic benchmarks or the high number of sediment toxicity units, pesticides are abundant in California surface waters.

“…Because PSD technology measures C free , the levels reported are meaningful. A draft chronic criterion for water toxicity has been described and proposed at 2 ng l −1 (ppt) permethrins, which is a level similar to those measured in this study [ 35 ]. Permethrins have also been identified as a potential threat to beneficial insects, including honeybees [ 36 ].…”

It is difficult to assess pollution in remote areas of less-developed regions owing to the limited availability of energy, equipment, technology, trained personnel and other key resources. Passive sampling devices (PSDs) are technologically simple analytical tools that sequester and concentrate bioavailable organic contaminants from the environment. Scientists from Oregon State University and the Centre Régional de Recherches en Ecotoxicologie et de Sécurité Environnementale (CERES) in Senegal developed a partnership to build capacity at CERES and to develop a pesticide-monitoring project using PSDs. This engagement resulted in the development of a dynamic training process applicable to capacity-building programmes. The project culminated in a field and laboratory study where paired PSD samples were simultaneously analysed in African and US laboratories with quality control evaluation and traceability. The joint study included sampling from 63 sites across six western African countries, generating a 9000 data point pesticide database with virtual access to all study participants.
