UNM Pesticide Assessment: Introduction
Since World War II, pesticide use in the United States of America and the world has steadily increased (Pimental et al. 2007 and Watanabe 2014). Pesticide use is continuing on its trend of exponential growth even now, for industrial agriculture is now the world’s primary food system and requires chemicals in order to support the vast monocultures that exist (Pimental et al. 2007 and Watanabe 2014). In addition, cities are steadily increasing in size and population (Pimental et al. 2007). As urban centers are growing more rapidly than ever before, so are the pest populations occupying the urban centers, including cockroaches (Pimental et al. 2007). Pesticides are viewed as an obvious solution to the health and sanitation issues associated with such pests. As time passes, pests grow resistant to the poisons, so new ones need to be found to replace them (Maund et al. 2012 and Watanabe 2014). This results in an endless cycle of chemicals in and out of the market, and it is no easy task to monitor these chemicals (Maund et al. 2012 and Watanabe 2014). What does this mean for living beings that encounter the chemicals?
For larger beings, such as humans, the enormous rate of pesticide application means 67,000 pesticide poisonings in the United States alone (Pimental et al. 2007). On average, 27 U.S. citizens die annually from pesticide poisonings (Pimental et al. 2007). Various research around the world also shows that chronic exposure to pesticides leads to increased incidences of cancer and obesity (Wei et al. 2014 and El-Zaeney et al. 2013). For example, in a long-term study from Australia it was found that women become more likely to develop breast cancer as the amount of pesticides in the environment increases (El-Zaeney et al. 2013). In addition, women aged 25 years or younger are at the highest risk for developing breast cancer at some point in their lives if they are regularly exposed to pesticides in their everyday environments (El-Zaeney et al. 2013).
For smaller beings, such as insect pollinators (these include bees, butterflies, and flies), the consequences of the enormous rate of pesticide application are catastrophic. Pollinator populations around the world are declining, with the most notable declines occurring in populations of honey bees (Henry 2012, Pettis 2013), bumble bees (Mommaerts et al. 2010, Whitehorn et al. 2012), and monarch butterflies (Watanabe 2014). Data is lacking for most non-commercial pollinators (Easton and Goulson 2013), so the status of wild pollinator populations is inferred from the collapse trends of these charismatic species. A number of environmental issues have been named as contributors to population declines, but pesticides have been identified as the leading cause (Watanabe 2014). Pesticides that have appeared in the past decade are specifically identified as key contributors to decline. These pesticides include a class of chemicals called neonicotinoids, such as imidachloprid, clothianidin, acetamiprid, thiacloprid, and thiamethoxam(Easton and Goulson 2012, Henry 2012, Mommaerts et al. 2010, and Whitehorn et al. 2012). Synthetic pyrethrins such as bifenthrin, fluvinate, permethrin, fipronil, and deltamethrin are also included among the deadliest chemicals known to pollinators (Maund et al. 2012). A total of twelve chemicals have been listed as the main chemicals that lead to pollinator decline. In addition to the neonicotinoids and synthetic pyrethrins already named, endosulfan and spinosad are on the top twelve list (Watanabe 2014). These chemicals mainly appear in agricultural situations, rendering agricultural sites the most toxic to pollinators across the globe (Watanabe 2014). Therefore, urban areas have been named as the current best refuge for pollinators (Pimental et al. 2007 and Watanabe 2014). Although cities widely use pesticides as well, they are more hospitable to pollinators than the agricultural areas because normally the pollinators’ food source is not directly contaminated (Watanabe 2014).
Clearly pesticides pose a problem to both people and pollinators, to say nothing of the rest of the world’s biodiversity. Pests also pose a problem, eating agricultural crops and spreading disease. In the context of these two large problems, universities in urban areas need to carefully plan how to best manage their pests and promote the health and well-being of humans and pollinators. I specifically name universities because young people are the most at risk for pesticide poisonings, and universities harbor numerous young people (El-Zaeney et al. 2013 and Pimental et al. 2007). Universities also harbor lush landscapes for pollinators. Therefore universities play a meaningful role in this issue. The University of New Mexico (UNM) is one such example. Naturally representatives of both sides of the issue weigh in and make claims (sometimes unsupported) about the sustainability and efficacy of UNM’s pesticide management. Therefore, we decided to perform a pesticide risk assessment for people and pollinators at UNM in order to dispel misconceptions people may have about pesticide use at UNM.
I teamed up with Omega Delgado, Sharlynn Lee, and Earl Shank from UNM’s Sustainability 434 class in order to determine the following:
1) Identify what pesticides are applied at UNM, where, and their effects.
2) Map key locations of people, pollinators, pesticides, and stakeholders on campus.
3) Maintain objectivity and professionalism throughout the project.
Deliverables for this project include a map of people, pollinator, and stakeholder populations on campus. We also planned to show pesticide application sites in our map. We hypothesized that people, pollinator, stakeholder, and pesticide concentration areas overlap or are in close proximity to each other on UNM’s main campus. We predicted such overlap would be a problem if chemicals that have been proven to cause harm to pollinators and people were present in the environment. We were not sure if the pesticides used on campus caused harm or not, so we also included a list that delineates the nature of the pesticides used on campus in our deliverables for this project.
