Risk Assessment 1 Running head RISK ASSESSMENT Risk Assessment Student Name College Name Risk Assessment It is with much consideration on both sides that I have come to my decision and I hope everyone will understand While going over the information provided and assessing all areas of possible contamination sickness and even the possibility of deaths caused by both hazards we are faced with I could only make one decision Over the past few days I have contemplated the good that can come from spraying our wetlands with the pesticide Malathion and I have also considered the damage that can be done It has been a long hard process of deliberating with my wants and my conscious but I have finally decided So without taking any further time from the council members my decision is against spraying with the pesticide Malathion This decision is based on a risk assessment that I did with the information provided by both sides The need is great to stop the spread of the West Nile Virus WNV but it does not justify the use of a pesticide that could have a devastating effect on our natural environment With very little evidence that this pesticide will not contaminate the very water we use to irrigate our fields or even kill the local wildlife I must say that we need to look for alternative ways of dealing with our mosquito problem Since the population of mosquitoes is dependent on the female of the species and the females are the only ones that feed on blood which allows them to produce eggs 1997 then a study on the females might be our best defense If we can isolate the chemical needed to produce their eggs and alter it then their need for feeding would cease We could also look at the breeding grounds of the mosquito and set up observation stations and control stations to try and reduce the larva that will turn into mosquitoes Since these larva oat near the surface of the water a sweep of the water with small nets at least twice a week could slow the growth population and reduce the chances of tourists or our locals contracting the WNV This is only a suggestion for the possible short term control of the mosquito population however for a long term control I feel we need to find a treatment for the disease Any attempt in trying to eliminate the mosquito population could result is a much larger environmental problem We need t try and keep it safe and simple One of the reasons I made this decision is based on the rates that mosquitoes bread If their species only lives around a week then their need to breed constantly is there With this need our need to continuous spraying of the pesticide is also present The pesticide Malathion has been reported that it breaks down into harmless other chemicals shortly after being sprayed however this report does not state that it was sprayed over and over again in the same place Without a substantial report about continuous use in one area and the use has provided no negative effect whether ecological or biological then we cannot accept the use of this pesticide If the pesticide is only used once I feel there would not be a substantial kill in the mosquito population and if the spraying is a constant job of once a week then we are taking a chance on destroying our eco system and along with it many different species including the people the rely on the tourists This does not take into account the possibilities of the people getting sick or even worse due to the exposure of the pesticide Since this poison will be distributed via aerial drop the wind currents can carry the pesticide into the human population causing havoc and possible death especially to the young This is an unacceptable chance that we do not have to take and will not take just yet We need to continue our fight against the WNV by finding a treatment or even a cure not by poisoning our environment Sometimes the war that is won is the one fought behind the front lines Reference 1997 Using live insects for in elementary classrooms The University of Arizona Arizona Center for Insect Science Education Outreach
