【摘要】：目的分析成都市畜禽血制品中甲醛本底含量及污染狀況,并對畜禽血制品中甲醛的風險進行初步評估。方法對全市范圍內(nèi)畜禽血制品中甲醛含量進行測定,結(jié)合成都市居民膳食消費數(shù)據(jù),計算成都市居民甲醛暴露量及安全限值(MOS),采用點評估的方法開展成都市居民攝入畜禽血制品中甲醛的風險評估。結(jié)果畜禽血制品及新鮮畜禽血中甲醛平均含量(中位數(shù))分別為2.51 mg/kg、2.53 mg/kg,但是在畜禽血制品中明顯存在個別甲醛含量極高的現(xiàn)象,最高值為3 200.00 mg/kg。采用平均暴露量的點評估模型獲得的畜禽血制品中甲醛急、慢性暴露的MOS分別是780、2 500,而采用高端暴露量的點評估模型獲得的甲醛急、慢性暴露的MOS分別是0.5、0.9。結(jié)論成都市大部分畜禽血制品可能會有一個較低的本底含量,但不排除部分的畜禽血制品中甲醛含量極高,提示可能存在一個人為添加的過程。采用高端暴露量評估提示該物質(zhì)對人體健康的風險超過了可以接受的限度,應當采取適當?shù)娘L險管理措施。
[Abstract]:Objective to analyze the content and pollution of formaldehyde in blood products of livestock and poultry in Chengdu, and to evaluate the risk of formaldehyde in blood products of livestock and poultry. Methods the formaldehyde content in the blood products of livestock and poultry was determined in the whole city, and the dietary consumption data of Chengdu residents were combined. The formaldehyde exposure and safety limit of Chengdu residents were calculated and the risk assessment of formaldehyde intake in blood products of livestock and poultry was carried out by using point evaluation method. Results the average formaldehyde content (median) in blood products of livestock and poultry was 2.51 mg / kg and 2.53 mg / kg, respectively. However, there was a very high concentration of formaldehyde in the blood products of livestock and poultry, the highest value was 3 200.00 mg 路kg ~ (-1) 路kg ~ (-1). The MOS of the blood products of livestock and poultry obtained by the point assessment model of average exposure amount was 780,25000.The MOS of chronic exposure was 0.50.9g / L, while that of the point assessment model with high exposure level was 0.50.90.The results showed that the formaldehyde in the blood products of livestock and poultry was acute, and the MOS of chronic exposure was 780g / 2 500, respectively. Conclusion most livestock and poultry blood products in Chengdu may have a relatively low background content, but it is not excluded that the formaldehyde content in some animal and poultry blood products is extremely high, suggesting that there may be a process of artificial addition. The use of high-end exposure assessments indicates that the risk to human health of the substance exceeds acceptable limits and appropriate risk management measures should be taken.
