AB  - BACKGROUND: Diisocyanates are widely used in surface coatings, polyurethane (PUR) 
      foams, adhesives, resins, elastomers, binders, and sealants. Isocyanate exposure 
      is irritative to the skin, mucous membranes, eyes, and respiratory tract. The 
      most common adverse health outcome associated with isocyanate exposure is asthma 
      due to sensitization. OBJECTIVE: The goal of this study is to find statistical 
      predictive model to determine the relationship between airborne hexamethylene 
      diisocyanate (HDI) and selective psychrometric variables. MATERIALS AND METHODS: 
      All air samplers (by midget impinger) were collected by mini personal sampler 
      pump fixed to work stations near the source of pollution. The air samples and 
      psychrometric parameters were separately collected and determined in a working 
      shift for three periods of 2 h, each at a flow rate of 2 l/min in an impinger 
      containing a solution of reagent of dimethyl sulfoxide in tryptamine [US National 
      Instituteof Occupational Safety and Health (NIOSH), 1994]. RESULTS: There was a 
      significant correlation between HDI concentration and relative humidity and dry 
      bulb temperature (P < 0.05). No significant correlation was seen between altitude 
      and dimension of PUR factories (P > 0.05). CONCLUSIONS: The finding of the study 
      may be a useful initial tool in estimating possible HDI pollution situation in 
      the PUR workplaces, based on simple psychrometric factors (indoor air temperature 
      and relative humidity).
