In the phosphate fertilizer industry in Karnataka, India, 24 employees had their urinary fluoride concentrations reported. Using NIOSH technique 7902, gaseous fluoride particles were analyzed. Urinary fluorides were greater in fertilizer industry workers. As anticipated, particulate fluorides and respirable dust concentrations among the fertilizer industry personal monitoring showed a substantial significant positive correlation (r>0.36, p>0.01) between urine fluoride levels among exposed workers. These results suggest that there is a significant risk of fluoride exposure for phosphate fertilizer workers in India. For Indian phosphate fertilizer industries, it is advised that effective regulatory and protective measures be put in place to confirm the Occupational Safety and Health Hazards (OSHA) regulations or the Environmental Health & Safety (EHS) guidelines.
