【摘要】：為探明廣州地區(qū)丙環(huán)唑和矮壯素在葉菜的殘留以及膳食暴露風(fēng)險(xiǎn)情況,對(duì)2016年第2季度廣州市9個(gè)區(qū)農(nóng)貿(mào)市場(chǎng)和超市的芥藍(lán)、菜心和普通白菜樣品中丙環(huán)唑和矮壯素殘留水平進(jìn)行了分析。應(yīng)用點(diǎn)評(píng)估和基于@Risk評(píng)估軟件的概率評(píng)估方法 ,對(duì)這3種蔬菜中丙環(huán)唑和矮壯素殘留膳食暴露風(fēng)險(xiǎn)進(jìn)行了研究。結(jié)果顯示,芥藍(lán)、菜心、普通白菜中丙環(huán)唑殘留均值為0.162 8~0.002 8 mg/kg,最高為芥藍(lán),與菜心和普通白菜差異顯著,平均檢出率為100%~70.25%,最高為芥藍(lán),與普通白菜差異顯著。矮壯素殘留平均值為0.010 9~0.001 0 mg/kg,最高為菜心,三者間差異不顯著,平均檢出率為14.99%~8.46%,最高為芥藍(lán),三者間差異不顯著。通過(guò)膳食攝入3種蔬菜,丙環(huán)唑殘留暴露急性風(fēng)險(xiǎn)熵為1.81~7.93,99%人群暴露慢性風(fēng)險(xiǎn)熵為1.02~25.03,0.1%人群存在芥藍(lán)丙環(huán)唑膳食暴露慢性風(fēng)險(xiǎn);矮壯素殘留暴露急性風(fēng)險(xiǎn)熵為55.14~62.26,100%人群暴露慢性風(fēng)險(xiǎn)熵為3.26~8.11。3種蔬菜中丙環(huán)唑和矮壯素殘留膳食暴露風(fēng)險(xiǎn)在可接受范圍。
[Abstract]:In order to find out the residue of pyrazole and dwarf in leafy vegetables and the risk of dietary exposure in Guangzhou, mustard was used in 9 farmers' markets and supermarkets in Guangzhou in the second quarter of 2016. The residual levels of propiconazole and dwarf in Chinese cabbage and Chinese cabbage were analyzed. The risk of residual dietary exposure to pyrazole and dwarf in these three vegetables was studied using point assessment and probabilistic assessment based on the software of @ risk. The results showed that the mean value of propiconazole residue in Brassica oleracea, Brassica rapae and Brassica campestris was 0.162 ~ 0.0028 mg/kg, the highest was Brassica oleracea, and there was a significant difference between Brassica oleracea and Brassica campestris, the average detection rate was 1000.25 and the highest was mustard, which was significantly different from that of common cabbage. The average residual value of dwarf hormone was 0.010 mg/kg, the highest was cabbage, and the difference among the three was not significant. The average detection rate was 14.999.46 and the highest was kale. There was no significant difference among the three groups. By dietary intake of three vegetables, the acute risk entropy of residual exposure to pyrazole was 1.81 ~ 7.9399%. The chronic risk entropy of exposure to chronic risk was 1.02% 25.03% of the population had chronic risk of dietary exposure. The acute risk entropy of Dwarf residual exposure was 55.140.62.26100% of the population exposed to chronic risk entropy was 3.260.8.11.3 species of vegetables pranocyrazole and Dwarf residual dietary exposure risk in acceptable range.
