凡口铅锌矿床地球化学特征及成矿作用分析

凡口铅锌矿床是发育于碳酸盐岩建造中的海底热泉喷溢沉积矿床,以“一大二富三集中”的特点和典型的地质地球化学特征吸引着中外矿床地质工作者。常量元素和矿化元素的分布、矿物包裹体特征、稀土元素组成和硫同位素组成反映出该矿床与外生作用有关。铅同位素组成具有壳源和下地壳来源铅的特征,矿物包裹体水氢、氧同位素组成表明,成矿溶液可能与深层建造水有关,后期与大气降水有关。矿区主要矿层经历海底热泉喷溢沉积-成岩的演化。

苏丹红I对小鼠卵巢的损伤作用及对Caspase-3和Ki-67表达的影响

苏丹红是一种人工合成偶氮染料,可引起肝脏及泌尿系统等多个脏器的肿瘤,但苏丹红对生殖系统的毒性研究较少。本研究以昆明小鼠为受试对象,探讨苏丹红I对小鼠卵巢组织Caspase-3和Ki-67表达的影响。将24只昆明小鼠随机分为:对照组、低剂量(60 mg·kg~(-1))、中剂量(120 mg·kg~(-1))、高剂量(240 mg·kg~(-1))4组,6只/组。胃灌4周,4周末处死。HE染色观察各组卵巢组织病理变化,免疫组化法检测卵巢组织Caspase-3和Ki-67表达,Real time PCR检测卵巢组织Caspase-3和Ki-67 m RNA表达,Western blotting检测卵巢组织中Ki-67及Caspase-3蛋白表达。与对照组比较,实验组卵巢中Caspase-3阳性细胞率显著升高(P0.05),而Ki-67阳性细胞率显著降低(P0.05),Real time PCR及Western blotting结果与免疫组化法结果一致。本实验发现苏丹红染毒后颗粒细胞的Caspase-3表达增加,且Caspase-3表达呈剂量依赖性,但Ki-67表达受到抑制。     

Characteristics of PM<Subscript>2.5</Subscript>, CO<Subscript>2</Subscript> and particle-number concentration in mass transit railway carriages in Hong Kong

Fine particulate matter (PM_2.5) levels, carbon dioxide (CO₂) levels and particle-number concentrations (PNC) were monitored in train carriages on seven routes of the mass transit railway in Hong Kong between March and May 2014, using real-time monitoring instruments. The 8-h average PM_2.5 levels in carriages on the seven routes ranged from 24.1 to 49.8 µg/m³, higher than levels in Finland and similar to those in New York, and in most cases exceeding the standard set by the World Health Organisation (25 µg/m³). The CO₂ concentration ranged from 714 to 1801 ppm on four of the routes, generally exceeding indoor air quality guidelines (1000 ppm over 8 h) and reaching levels as high as those in Beijing. PNC ranged from 1506 to 11,570 particles/cm³, lower than readings in Sydney and higher than readings in Taipei. Correlation analysis indicated that the number of passengers in a given carriage did not affect the PM_2.5 concentration or PNC in the carriage. However, a significant positive correlation (p < 0.001, R ² = 0.834) was observed between passenger numbers and CO₂ levels, with each passenger contributing approximately 7.7–9.8 ppm of CO₂. The real-time measurements of PM_2.5 and PNC varied considerably, rising when carriage doors opened on arrival at a station and when passengers inside the carriage were more active. This suggests that air pollutants outside the train and passenger movements may contribute to PM_2.5 levels and PNC. Assessment of the risk associated with PM_2.5 exposure revealed that children are most severely affected by PM_2.5 pollution, followed in order by juveniles, adults and the elderly. In addition, females were found to be more vulnerable to PM_2.5 pollution than males (p < 0.001), and different subway lines were associated with different levels of risk.

基于社区的地质遗迹旅游开发研究^＊——以四川八台山省级地质公园为例

地质遗迹的开发和保护是地质遗迹资源丰富地区面临的现实问题。在介绍了社区生态旅游定义以及地质公园走社区生态旅游发展道路的意义的基础上,利用国外较为成熟的社区生态旅游理念为指导,对八台山省级地质公园进行研究。提出八台山省级地质公园社区生态旅游的开发构想：①搞好地质公园内的生态旅游规划工作;②实施补偿机制;③搞好社区生态旅游示范区：走“政府引导＋社区参与＋企业经营＋科研机构介入”的开发模式,并提出相应的开发项目,为经济不发达地区地质遗迹的合理开发提供示范作用和理论依据,避免不必要的人力、物力、财力的浪费,有利于走可持续发展道路。     

HDTMA改性粉煤灰沸石对水中铬酸盐的吸附

以自制HDTMA-粉煤灰沸石为吸附剂,对铬酸盐的吸附进行了实验研究。讨论了吸附剂的投入量、废水pH值、吸附温度和吸附时间等各因素对Cr（VI）去除率的影响。研究表明：pH值对Cr（VI）的吸附效率无显著影响,且在HDTMA-粉煤灰沸石的投加量为20 g/L、吸附温度为30℃、吸附时间为60 min的条件下,Cr（VI）的去除率可达90%左右。
