Environmental Hazards Caby Flotation Cells

Sources of Hazards Types of Data Needed As shown in Figure 1–1 for each hazard to be evaluated in the ongoing study it will be necessary to determine where the substance comes from and how much of it enters the environment in order to 1) derive exposure data and 2) take effective steps towards decreasing exposure from a particular source Two types of sources of pollutants include
