Support your choice by describing the types of health consequences associated with the pollutant (including any susceptible populations), its major sources, and when the standards were last reviewed and/or changed. Then, provide a brief explanation of one or more global implications for regulation of this pollutant by the United States. Be sure to cite your sources. Response: ?????
