The high usage of pesticides in the subtropical climate of Florida presents a worst case scenario under which registrations that may impact public health and the environment must be judged A methodology is presented that utilizes chemical environmental fate factors in conjunction with chronic toxicity parameters to better assess new active ingredients that are submitted for registration A ranking index related to leaching potential is assigned to a pesticide as a preliminary screening process If the index falls within a certain numerical range, then a more in depth analysis of the environmental fate and toxicological data for the pesticide occurs A decision matrix that incorporates the results of chronic toxicity analysis and computer simulation of leaching behavior is then applied to the pesticide to decide which registration action may be appropriate This tool has widespread potential for assessing the leaching potential of pesticides to, and the chronic toxicity of pesticides in, ground water
