6 Overview of the Urban Pesticide Reduction Program (UPRP) Effects of Pesticides on Human and Environmental Health What is a Pesticide?

7 USA: 74-90% of households utilize pesticides on an annual basis (Whitmore et al. 1994; Landrigran et al. 1999, Fishel 2007) Oregon: 46% of households used pesticides in 2007 (PURS 2008) Portland Metro: 29% of households used lawn and garden pesticides and 17% used indoor pesticides (Peters et al. 2007)

8 Pesticide use is generally underreported, and risk perception is generally underestimated (Nieuwenhuijse et al. 2005) PURS (Oregon’s Pesticide Use Reporting System) Survey “participants were unable to determine what products were pesticides” “continued concerns about the ability of pesticide users to read the label and correctly identify information” “Moss control products accounted for 47% of the pounds of active ingredient, but only 2% of the reports identified moss control as the purpose”

10 Reduce pesticide use in residential areas – both inside and outside of home. Increase knowledge about pesticides. Safe pesticide use Alternatives to pesticides

11 Three classes Class 1: Overview of UPRP. Pesticides, defined. Assess your pesticide use in the home, garden and lawn. Class 2: Reading a pesticide label. Proper use, storage and disposal of pesticides. Class 3: Environmental fate of pesticides. Alternatives to pesticides for pest management. Prevention rather than reaction.

12 Does this program work? Does this program decrease pesticide use and increase knowledge? Voluntary, anonymous surveys Pre-tests Post-test Follow-Up (6 months following classes) IRB Approved (Institutional Review Board)

15 Take 3-5 minutes to think about your pesticide use over the last 12 months. On a piece of paper: list all of the pesticides that you have used OR list all of the pests for which you have used products

20 A 2000-2005 U.S. Geological Survey (USGS) study found a variety of pesticides in the lower Clackamas River mainstem and tributaries, along with trace-level detections of pesticides in treated drinking- water samples. A total of 63 pesticide compounds were detected. The herbicides atrazine and simazine were the most common, detected in half of the samples. High-use herbicides such as glyphosate and triclopyr/2,4-D-the active ingredients in RoundUP TM and Crossbow TM, respectively-also were frequently detected...." The full press release may be viewed at: http://www.usgs.gov/newsroom/article.asp?ID=1895 http://www.usgs.gov/newsroom/article.asp?ID=1895 The full report may be found at: http://pubs.usgs.gov/sir/2008/5027/http://pubs.usgs.gov/sir/2008/5027/ March 18, 2008 Press release, USGS

22 Colony Collapse Disorder: worker bees in honey bee hives abruptly disappear Pesticides may be a contributing factor. Until scientists know more, it is best to use pesticides with caution. CCD Hive Healthy Hive

23 Organophosphates: commonly sold, broad spectrum, contact insecticide Will kill ladybugs, lacewings, bees, spiders, flower flies and other beneficial insects.

24 Cholinesterase is present in many organisms, including all mammals (like humans!) Cholinesterase is an enzyme that is ubiquitous in the human body Cholinesterase is critical for many nervous system functions

25 Organophosphates Irreversibly inhibits cholinesterase that is present in the human body Cholinesterase must be replaced, by the body, after exposure to an organophosphate pesticide Carbamates Temporarily inhibits cholinesterase that is present in the body Effects can be rapidly reversed (time required depends on level of exposure)

26 Negative effects of pesticides are amplified when pesticides are: Misused Overused Used at an inappropriate time Incorrectly stored Incorrectly disposed

27 Overview of the Urban Pesticide Reduction Program (UPRP) Effects of Pesticides on Human and Environmental Health What is a Pesticide?

28 A pesticide is any substance intended to control, destroy, repel, or attract a pest.

29 We determine what is a pest. Causes damage or economic loss Transmits or produces disease Pests can be animals (including insects). Pests can be unwanted plants. Pests can be microbes.

30 Is an EPA registration number on the container? If so, it is a pesticide. EPA Reg. No. 3120-280 Identifies manufacturer Identifies product

31 Toothpaste, mouthwash (regulated by FDA and not EPA) Fertilizers (except for weed and feed products) Compost tea Beneficial insects that eat insect pests Ladybugs, Lacewings, Preying Mantis, etc. Parasitoid wasps Nematodes Bt and spinosad are microrganisms that ARE pesticides

32 Do not have an EPA Registration Number Are deemed ‘demonstrably safe’ A complete list of Minimum Risk Pesticides can be viewed at: http://www.epa.gov/oppbppd1/biopesticides/regtools/25b_list.htm http://www.epa.gov/oppbppd1/biopesticides/regtools/25b_list.htm CitronellaWhite pepper Castor oilEgg whites and egg solids Cinnamon oilCitric acid Clove oilRosemary oil Dried BloodThyme oil Mint oilCorn gluten meal

33 Please take 10 minutes to complete the survey. We will revisit the different parts of the survey throughout the UPRP.

34 Was there a difference between your original narrative, and the checklist audit of your pesticide use?

35 Please bring a pesticide from home. We will be using this pesticide for an activity focused on reading labels. We will also discuss safe use, storage and disposal of pesticides, as well as the use of personal protective equipment.
