A modified computer hazard and operability study procedure

The application of modifications of the hazard and operability study method (Hazop) to process facilities using computer-based control systems has led to the development of computer Hazop (Chazop) procedures. A number of the Chazop procedures cited in the literature broaden the method and depart from the base documentation of the Hazop method. It is suggested that a robust Chazop method requires implementation at the line-by-line level of detail and as a separate, complementary study using the same base documentation (piping and instrumentation diagrams) as that used in the Hazop method.

南宁城市大气污染对人体健康的危害及治理对策

南宁市大气属煤烟型污染 ,大气的主要污染物为SO2 、NOx、TSP、降尘 ,虽然随着环境管理和污染治理工作的加强 ,污染物浓度逐年下降 ,但是工业区大气污染仍然较重。污染物流行病学调查显示 :工业区癌症和呼吸系统疾病死亡率均高于全市平均水平 2倍左右 ,城区又高于郊区 2倍 ,大气污染综合指数与呼吸内科门诊就诊人数呈正相关。用邓聚龙的灰色系统理论分析得知污染物对癌症和呼吸系统疾病死亡率有关联 ,关联度从大到小排序为 :TSP >降尘 >SO2 >NOx ,最后提出了大气污染治理的对策。

海州湾表层沉积物磷的吸附容量及潜在释放风险

利用磷吸附指数（PSI）、磷吸附饱和度（DPS）和磷释放风险指数（ERI）研究了2016年10月和2017年5月海州湾表层沉积物的磷吸附容量及潜在释放风险.结果显示,2016年秋季PSI变化范围为99.58~199.39[mgP/（100g）]/[μmol/L],DPS变化范围为23.118%~34.289%;2017年夏季PSI变化范围是130.29~198.57[mgP/（100g）]/[μmol/L],DPS变化范围为25.545%~42.135%,两次调查中PSI和DPS均表现出相反的平面分布趋势.PSI和Al_ox、Fe_ox呈显著正相关,说明Fe_ox和Al_ox是影响海州湾表层沉积物吸附磷的主要因素,且Fe_ox占主导作用;DPS与Al_ox和Fe_ox分别表现出了显著负相关性和极显著负相关性,说明Al_ox和Fe_ox含量的增大会降低表层沉积物的磷吸附饱和度.2016年10月磷释放风险指数（ERI）的变化范围为11.59%~34.18%,2017年5月磷释放风险指数（ERI）的变化范围为12.86%~32.34%,从2次调查结果整体来看,海州湾表层沉积物的磷释放风险为中度风险.     

Ecological Risk Assessment of Abandoned Shrimp Ponds in Southern Thailand

The potential ecological risks associated with contaminants from 15 abandoned shrimp ponds in southern Thailand were assessed at the screening level. Shrimp ponds reported as out of production for more than 2 years were selected as sampling sites. The assessment endpoint was identified as the protection of aquatic life from hazard of multiple agents or stressors in water or sediment from the ponds. The measurement endpoints were amount of toxic phytoplankton species, Yellow Head Viruses, SEMB viruses, oxytetracycline, cadmium, copper, and manganese. Data from field measurements and laboratory analyses obtained primarily from April to June 2003 were used in the risk analysis. The results showed that insignificant amounts of stressors were present, except for the metals. So, only concentration values of the metals were used in the calculation of hazard quotients (HQ) for risk characterization. The highest potential ecological risk characterized by the highest HQ value observed for each metal was 19 for manganese, 4.3 for cadmium, and 1.8 for copper. These findings indicated a need for further ecological risk assessment at a more detailed level to focus on the bioavailability and effects of metals from abandoned shrimp farms, with manganese the highest priority.
