煤中有害元素对环境和人体健康影响的评价参数

煤中有害元素对环境和人体健康影响的较为全面的评价体系一直未建立，环保部门也缺乏系统性评价参数对电厂等在煤煤过程中有害元素排向大气的释放量进行监测估算。本文在查阅大量资料（主要为外文）的基础上，认为评价煤中有害元素对环境和人体健康影响的参数应该包括以下方面的数据C、H、O、N、无机硫，有机硫，有害微量元素的含量，分布规律，赋存状态，迁移转化行为（在燃煤过程中），洁净能力，淋滤力，矿物质，有机化学特征，煤炭学特征，并对煤中有害元素的污染方法进行探讨，如果上述各参数的数据被全面提供，并据此数据作针对性的抑制措施，煤中有害元素对环境和人体健康危害影响必将降低到最小。

蔬菜的硝酸盐污染及其控制措施

硝酸盐对人体健康危害极大。蔬菜中的硝酸盐含量比其它作物高，但不同种类蔬菜对硝酸盐的积累有很大的差异。我国大城市郊蔬菜的硝酸污染较严重，主要原因是偏施氧肥，也与土壤、气温、光照及蔬菜种类等有关。应从合理施用肥料等5方面采取措施，控制蔬菜中的硝酸盐含量。     

A 1 and 6 month follow-up of prenatal diagnosis patients who lost pregnancies

This paper reports results of an exploratory study of prenatal diagnosis patients who experienced voluntary terminations of pregnancy following the detection of an abnormality or spontaneous miscarriages. The 121 participants were part of the national collaborative Chorionic Villus Sampling and Amniocentesis Study. They completed semi-structured telephone interviews and mailed questionnaires at 1 month and 6 months after the pregnancy losses. Scores on the Profile of Mood States showed that mood levels improved significantly over time. However, there were some declines in loss-related support from partners and others. The persisting distress and difficulties of a minority highlight the variability in women's responses to pregnancy losses. Women who lost pregnancies later in gestation, showed the greatest mood disturbances at initial assessments, used professional mental health assistance after the loss, or reported less satisfactory loss-related support from significant others showed the greatest levels of mood disturbance at the six-month assessment. Follow-up contacts with patients who lose pregnancies should be used to inform women about the variation in possible grief reactions, to assess the extent of support the women are receiving from their partners and significant others, and to provide additional follow-up or referral of those experiencing the greatest distress.

2000年北京大气中SO2浓度削减50%的健康效益—人力资本法实例研究

人力资本法是评估环境污染健康损害价值（或治理污染的健康效益）的常用方法，但在发达国家，它逐渐被隐含价格法等所取代。本文通过实例研究，探讨了人力资本法在我国目前的适用性，研究结果表明，当使用流行病学关于疾病负担的计量方法（ＹＰＬＬ）时，人力资本法在我国有很大的适用性。

Relationship between abundance of rodents and damage to agricultural crops

Developing a relationship between pest abundance and damage to crops is essential for the calculation of economic injury levels (EIL) leading to informed management decisions. The crop modelling framework, APSIM, was used to simulate the impact of mouse damage on yield loss on wheat where a long-term dataset on the density of mice was available (1983–2003). The model was calibrated using results from field trials where wheat plants were hand clipped to imitate mouse damage. The grazing effect of mice was estimated using the population density, daily intake per mouse and the proportion of wheat grain and plant tissue in the diet to determine yield loss. The mean yield loss caused by mice was 12.4% (±5.4S.E.; range −0.5 to 96%). There were 7/21 years when yield loss was >5%. A damage/abundance relationship was constructed and a sigmoidal curve explained 97% of variation when accounting for different trajectories of mouse densities from sowing to harvest. The majority of damage occurred around emergence of the crop when mouse densities were >100 mice ha⁻¹. This is the first time that field data on mouse density and a crop simulation model have been combined to estimate yield loss. The model examines the efficacy of baiting and how to estimate EILs. Because the broadscale application of zinc phosphide is cheap and effective, the EIL is very low (<1% yield loss). The APSIM model is highly flexible and could be used for other vertebrate pests in a range of crops or pastures to develop density/damage relationships and to assist with management.
