Health Risk Assessment of Wastewater with Carbinol in Gas Field

The carbinol in wastewater from inhalation and direct contact present more risk to human health, as well as cause hazard to ecological environment through waste water emission directly and soil infiltration. In this paper, health risk assessment of wastewater with carbinol in gas field is performed using mathematical models of non-carcinogenic health risk assessment. The results show that the non-carcinogenic health risks caused by wastewater with carbinol are in the range of 6.33×10-5 to 9.20×10-5, which are much higher than the acceptable risk level 7.00×10-5. Through the calculation of the threshold of the carbinol concentration in the wastewater, the carbinol concentration in the wastewater is less than 24500mg/L, not on human body risks. However, the carbinol concentration in the wastewater is much than 24500mg/L, it is a health risk to human body, which provides the scientific basis for the prevention and mitigation of wastewater with carbinol health risks.
