水泥生产急性硫化氢中毒事故分析

硫化氢（H2S）是无色、剧毒,有臭鸡蛋气味的刺激性气体,人体吸入后可致急性中毒,且中毒多为群体急性中毒事件。其毒性作用的主要靶器官是中枢神经系统和呼吸系统,亦可伴有心脏等多器官损害,吸入高浓度硫化氢后立即发生急性中毒,引起昏迷,呼吸与血管中枢麻痹、细胞内缺氧和窒息,     

从鸡蛋有"身份证"说起

据报载,即使像鸡蛋这样小的产品,德国人也一点不马虎.德国市场上销售的鸡蛋通常用硬纸盒包装,见不到散装的.最令人惊讶的是,盒里每一只鸡蛋都有说明"身份"的红色编码.     

鸡蛋有乳头？

近日，四川广安武胜县盛传一条新闻——“彭川家的鸡生了一个‘怪蛋’”。彭川是小学六年级学生，他说：“怪蛋是我家的一只母鸡昨天产下的。”这个蛋长约2厘米，宽1厘米多，蛋的一端还有个形似乳头的突起，拿到手上轻飘飘的，用称中药的秤来称，只有两克重。畜牧师介绍，怪蛋是当地村民过去俗称的“鬼蛋”，其形成原因是母鸡体内分泌的卵蛋白不足，里面只有蛋清没有蛋黄，实际上就是蛋生长时营养不足。     

催化光度法测定鸡蛋中的碘

研究了在 80～ 1 0 0℃条件下制备样品 ,利用催化光度法间接测得鸡蛋中碘的含量。在 0～ 0 .0 2 1 mg/ L内符合比耳定律 ,摩尔吸光系数达 2 .0 3× 1 0 5L.mol- 1 .cm- 1。可用于其它食品中微量碘的测定。     

日常吃鸡蛋的十大误区

鸡蛋是日常生活中的常见食物,不过在食用鸡蛋的过程中我们常常有些误区,这些误区都会严重影响我们对于鸡蛋营养的吸收,下面我们就给大家说说日常生活中鸡蛋的营养误区有哪些吧。     

应用EM生物技术降低鸡蛋胆固醇的试验研究

应用EM生物技术饲养蛋鸡,可以降低鸡蛋胆固醇含量52.05 %?67. 78 %,同时可以保障高蛋白营养,降低脂肪含量,成为老少皆宜的 健康食品。      

燕翅鲍参不敌牛奶鸡蛋

鱼翅与燕窝、海参、鲍鱼一起被称为四大美味，历来被视为益寿、养颜的珍品。“这些所谓的珍稀食物在营养价值上并没有什么特别之处。”多位营养专家日前表示，这些昂贵的食品所含的营养成分主要是蛋白质，而蛋白质在其他食物中也有，甚至含量更丰富，品质更优良。     

基质固相分散萃取-液相色谱-质谱/质谱测定牛奶和鸡蛋中的烷基酚和双酚A

体内、体外实验以及野外调查的结果表明，烷基酚(alkylphenol，AP)和双酚A(bisphenolA，BPA)，尤其是壬基酚(nonylphenol，NP)、辛基酚(octylphenol，OP)和双酚A等具有雌激素效应和慢性毒效应．近年来已经成为当前国际上研究的热点。     

Polybrominated diphenyl ethers in chicken tissues and eggs from an electronic waste recycling area in southeast China

The levels and distributions of polybrominated diphenyl ethers (PBDEs) in chicken tissues from an electronic waste (e-waste) recycling area in southeast China were investigated. Human dietary intake by local residents via chicken muscle and eggs was estimated. The mean PBDEs concentrations in tissues ranged from 15.2 to 3138.1 ng/g lipid weight (lw) and in egg the concentration was 563.5 ng/g lw. The results showed that the level of total PBDEs (PPBDEs) in the chicken tissue was 2–3 orders of magnitude higher than those reported in the literature. The large di erence of PPBDEs concentrations between tissues confirmed that the distribution of PBDEs in tissues depend on tissue-specificity rather than the “lipid-compartment”. BDE-209 was the predominant congener (82.5%– 94.7% of PPBDEs) in all chicken tissues except in brain (34.7% of PPBDEs), which indicated that deca-BDE (the major commercial PBDE formulation comprising 65%–70% of total production) was major pollution source in this area and could be bioaccumulated in terrestrial animals. The dietary PBDEs intake of the local residents from chicken muscle and egg, assuming only local bred chickens and eggs were consumed, ranged from 2.2 to 22.5 ng/(day kg body weight (bw)) with a mean value of 13.5 ng/(day kg bw), which was one order of magnitude higher than the value reported in previous studies for consumption of all foodstu s.
