Re: LIMIT VALUES FOR DIOXINS

    This question is interesting and I wonder if anyone could answer a 
    few more to help my understanding?
    
    
    I wonder how fentograms per cubic meter in the air co-relates to 
    uptake.  Is the method primarily air deposition onto vegetation 
    and then consumption by animals and concentration in fats?  Or is 
    there more transport from the air to the soil to the water and 
    then up through the food chain?  
    
    Is there a "background" level in soils from historical deposition? 
    
    Thanks,
