ABSTRACT
OBJECTIVES:
This study was conducted to determine the cadmium (Cd) concentration in brown and polished rice collected from the 9 farms in Barangay Real, Calamba City. This study also assessed the non-cancer health risk to adults (?20 years old) of long-term consumption of rice with Cd using the non-cancer hazard quotient (NHQ).METHODS:
Rice grains with hull were collected in November-December 2013. Both rice types were analyzed for Cd using a graphite furnace atomic absorption spectrophotometer (GFAAS). The NHQ was calculated by dividing the estimated daily intake of Cd via rice consumption by the oral reference dose (RfD) for Cd.RESULTS:
Mean Cd concentrations in brown and polished rice collected from the 9 farms in Barangay Real ranged from 0.0062 to 0.0725 mg/kg and 0.0047 to 0.0778 mg/kg, respectively. The NHQ values of Cd in both rice types were less than 1.0 for adults (?20 years old).CONCLUSION:
Cd concentrations in brown and polished rice from the 9 farms did not exceed the 0.4 mg/kg maximum allowable Cd concentration in rice set by FAO/WHO. Since the NHQ did not exceed 1.0, long-term exposure to Cd through consumption of brown and polished rice from these farms is unlikely to cause non-cancer health effects in adults (?20 years old). It is unlikely for adults to develop kidney diseases such as tubular proteinuria, decreased glomerular filtration rates, and itai-itai disease.
