Pollutant: Effects of mold as an indoor pollutant and how it can cause asthma Please answer in paragraph format for each question. 1- What are the history, chemical composition and physical properties of the pollutant? 2- What are its sources and modes of transport? 3- How prevalent is it in the environment and where would human exposure occur? Are animals or other environmental systems also affected? 4- What are all the modes of exposure (e.g. Dermal, inhalation and/or ingestion)? 5- What are the different ways one may measure the pollutant in the environment and in people to estimate exposure and dose? 6- Are in vivo and /or in vitro methods or direct and/ or indirect methods used? 7- What populations are affected? Are some populations particularly at risk (with high exposures and/or high sensitivities)? 8- Using time/activity patterns what is an estimate of either a daily or yearly exposure of a typical population, a specific subpopulation or an individual (show the calculations and where you got the data on a separate piece of paper)? 9- What are an estimated internal dose and an estimated biologically effective dose of the above exposure of the individual or population
