PURs are collected by the California Department of Pesticide Regulation CADPRR) for any commercial application of restricted-use pesticides (defined as "agents with harmful environmental or toxicologic effects") and, since 1990, all commercial uses of pesticides regardless of toxicologic profile.
For a review of current knowledge of tungsten, including environmental chemistry, toxicologic properties, and ongoing investigation into its possible toxicity, see Koutsospyros et al. (2006).

These authors present a conceptual paradigm that integrates infectious disease and toxicologic environmental health research, promotes cross-disciplinary education and communication, and elucidates a fuller body of environmental health risk factors.
Basically, there are not enough peers on grant and contract review panels to provide a balanced evaluation of exposure science proposals, which are often inappropriately reviewed as if they were environmental science or toxicologic studies.
The evidence that mineral dust exposure poses a significant hazard to agricultural workers for interstitial lung disease is based on a handful of case reports, inferences from exposures to mineral dusts in other industries, studies of wild and farm animals exposed to environmental dusts, and toxicologic studies (Gylseth et al. 1984; Schenker 2000; Schoning 1996; Vallyathan et al. 2007).
Wherever possible and feasible, toxicologic and environmental epidemiological studies should be designed and have sufficient statistical power to quantify differential gender-based exposures and outcomes.
Recent publications have extensively reviewed and summarized the known toxicologic properties, environmental distribution, and potential health concerns related to PFOA (Kennedy et al. 2004; Kudo and Kawashima 2003; Lau et al. 2007).
In some areas of toxicology, understanding of the toxicologic effects of mixtures of environmental chemicals is relatively well developed and can be modeled (see Liao et al. 2002).
Recent research has pointed to the developing immune system as a remarkably sensitive toxicologic target for environmental chemicals and drugs.
