石钢工伤事故规律分析及对策

石钢公司是以钢铁冶金为主的国家大型企业，是全国地方钢铁骨干企业之一，具有年产200万吨钢的能力。生产连续性强，节奏快，工艺、设备状况复杂，物料流转迅速，职工人数多，素质参差不齐。各种人、物、环境的不安全因素较多。本文探索了石钢公司事故规律，为加强预防工作，实现公司更高目标的安全生产提出了建议。     

原油对草原植被的影响

为了定量说明落地原油对大庆地区草原植被的影响，选择了四种植物群落进行浇原油试验，浇油厚度为0．2、0．4、0．8cm，浇油时间为秋、春、夏。试验结果表明原油对植物个体的影响因原油量、季节和植物种类的不同而不同，随原油量的增加影响增大。     

略论信息技术在农业气象灾害减灾中的应用

农业气象灾害减灾对策是一项十分复杂的系统工程，其系统可划分为两个子系统：农业气象灾害子系统和减灾对策子系统。农业气象灾害子系统包括灾害的发生、发展到消亡的整个过程。减灾对策子系统是指减轻灾害的对策措施，可概括为灾前防御、灾中抗御、灾后补救等。其系统涉及到灾害的监测、预报、防御、抗御、治理、灾情评估和减灾效益的分析等环节。因此，对这样一个系统工程，除总结和继承传统的农业气象灾害的减灾方法外，还需要利用现代的信息技术；遥感技术、人工智能技术、作物模拟技术等来提高防灾、减灾的能力。     

Weathering of lead bullets and their environmental effects at outdoor shooting ranges

Lead contamination at shooting range soils is of great environmental concern. This study focused on weathering of lead bullets and its effect on the environment at five outdoor shooting ranges in Florida, USA. Soil, plant, and water samples were collected from the ranges and analyzed for total Pb and/or toxicity characteristic leaching procedure (TCLP) Pb. Selected bullet and berm soil samples were mineralogically analyzed with X-ray diffraction and scanning electron microscopy. Hydrocerussite [Pb3(CO3)2(OH)2] was found in both the weathered crusts and berm soils in the shooting ranges with alkaline soil pH. For those shooting ranges with acidic soil pH, hydrocerussite, cerussite (PbCO3), and small amount of massicot (PbO) were predominantly present in the weathered crusts, but no lead carbonate mineral was found in the soils. However, hydroxypyromorphite [(Pb10(PO4)6(OH)2] was formed in a P-rich acidic soil, indicating that hydroxypyromorphite can be a stable mineral in P-rich shooting range soil. Total Pb and TCLP Pb in the soils from all five shooting ranges were significantly elevated with the highest total Pb concentration of 1.27 to 4.84% (w/w) in berm soils. Lead concentrations in most sampled soils exceeded the USEPA's critical level of 400 mg Pb kg(-1) soil. Lead was not detected in subsurface soils in most ranges except for one, where elevated Pb up to 522 mg kg(-1) was observed in the subsurface, possibly due to enhanced solubilization of organic Pb complexes at alkaline soil pH. Elevated total Pb concentrations in bermudagrass [Cynodon dactylon (L.) Pers.] (up to 806 mg kg(-1) in the aboveground parts) and in surface water (up to 289 microg L(-1)) were observed in some ranges. Ranges with high P content or high cation exchange capacity showed lower Pb mobility. Our research clearly demonstrates the importance of properly managing shooting ranges to minimize adverse effects of Pb on the environment.
