Fluorides 



15. Aggravates emphysema, asthma, and 

 bronchitis 



16. Impairs lung function in patients 

 with bronchitis-emphysema 



17. Eye and respiratory irritation and 

 impairment in performance of 

 student athletes 



18. Increased probability of motor- 

 vehicle accidents 



20. Irritant to respiratory tract 



21. Impairs lung function 



23. Impairs oxygen transport function 



27. (Discolors atmosphere) 



30. Increased storage in body 



31. (Lethal to animals eating 

 contaminated feed) 



34. Increased mortality from acute 

 exposures 



35. Causes sensory irritation 



36. (Damages property (paint)) 



39. Sensory irritation (odor) 



41. (Damages vegetation; harms animals) 



19. Alteration of oxygen consumption 



22. Acceleration of aging, possibly due 

 to lipid peroxidation and related 

 processes 



24. Increased general mortality and 

 coronary mortality rates 



25. Impairment of central nervous 

 system function 



26. Causal factor in atherosclerosis 



28. Factor in pulmonary emphysema 



29. Impairment of lung defenses such as 

 mast cells and macrophages or 

 altered lung function 



32. Impairment of hemoglobin and 

 porphyrin synthesis 



33. Probably decreases enzyme level 



37. Impaired sensory detection or 

 reflexes 



38. (Socio-cultural nuisance) 



40. Headache, nausea, and sinus 

 affections 



42. Fluorosis of teeth
