Pharmacology Report 1: Determination of an insecticide in cockroaches Introduction Pesticides are toxic and go through many different testings and procedures before they are put on the shelf in various industries. One general method that is used to asses toxicity of pesticides before released for sale is the LD50 (Lethal Dose 50) method. This method is conducted by calculating the most accurate dose of toxin that will kill animals 50% of the time. Before determining an accurate LD50 of a chemical

such as automobiles and aircrafts and even pesticides. With these great innovations come consequences. Such as global warming as Bill Mckibben states in his essay “The Environmental Issue from Hell”. In this essay Mckibben talks about how humanity in the past century has contributed to global warming by using fuel burning vehicles and aircraft. Before Pesticides‚ farmers had a tough time keeping crops alive due to insects. With the creation of pesticides this problem went away‚ but these chemicals

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities.

is the fact that nobody has an inkling as to why it occurs. CCD is no doubt one of the largest threat to the bee‚ but close behind is the increased use of neonicotinoid pesticides‚ and the spread of the Varroa mite. Neonicotinoid pesticides are used in almost every aspect of the agriculture industry. They are systematic pesticides‚ meaning that the seeds of the plant that are soaked in the mixture carries the chemicals into the plant‚ nectar and seed‚ and can be passed on to the bees. These chemicals

For example‚ most strains of GMO sweet corn already have pesticides in the seed before it is planted. If the planter did not know that they were pretreated to begin with‚ they might spray them more than necessary with pesticides‚ thus leading to run off into streams and rivers surrounding the fields (Becky Bell). Although it would have extra pest prevention qualities‚ it could hurt the environment. With even more pesticides in rivers this could lead to large fish kills and algal blooms in
