黄河三角洲滨海湿地植被的碳储量和固碳能力

在测定黄河三角洲滨海湿地盐生植被、湿生植被和水生植被3类天然湿地植被以及稻田的生物量、净初级生产力基础上,估算了黄河三角洲滨海湿地植被的总碳储量、总固碳能力和各种湿地植被单位面积的碳储量、固碳能力.黄河三角洲滨海湿地全部天然湿地植被和稻田的总碳储量为200.54×104 t,总固碳能力为69.91×104 t/a.其中,单位面积草本湿生植被和稻田的固碳能力低于当地地带性植被温带落叶阔叶林的平均固碳能力(1.06 kg/(m2·a)),高于中国陆地植被的平均固碳能力(0.49 kg/(m2·a))和全球陆地植被的平均固碳能力(0.41 kg/(m2·a));单位面积盐生植被和水生植被的固碳能力低于中国和全球陆地植被的平均固碳能力.结果表明,黄河三角洲滨海湿地植被总的碳储量较小,固碳能力较低,但植被的顺行演替过程会使其碳储量不断增大,固碳能力不断提高.因此,应该保护黄河三角洲滨海湿地的天然植被,尤其要保护芦苇(Phragmites australis)群丛等碳储量大、固碳能力较强的湿生植被.

Gender differences in DUI offenders in treatment in Texas

OBJECTIVE: This is a study of 8,464 adult women and 21,155 adult males who entered substance abuse treatment in Texas between 2000 and 2005. Participants were either on probation for driving under the influence (DUI), were referred to treatment by DUI probation, or had been arrested for DUI in the past year. METHODS: The female and male clients were compared on demographic characteristics, substance use patterns, DSM-IV diagnoses, and levels of impairment. T tests and chi square tests were used to determine significance and multivariate logistic regression identified predictors of completing treatment and being abstinent at follow-up. RESULTS: The proportion of females who were sent to treatment as a result of DUI increased from 27% in 2000 to 32% in 2005. Females were significantly more likely than males to be White (73% vs. 56%), to have used substances a shorter period of time (17 vs. 19 years), to be seeking custody to regain their children (11% vs. 2%), to meet the DSM criteria for drug dependence (32% vs. 23%), to have injected drugs (31% vs. 23%), to have used substances daily (42% vs. 40%), to have a depressive disorder (16% vs. 7%) or bipolar disorder (12% vs. 5%), and to be have been in treatment before (60% vs. 49%). In contrast, males were more likely to be alcohol dependent (49% vs. 44%). Females were less likely to complete treatment (67% vs. 72%) and reported significantly more days of problems on the 6 domains of the ASI at both admission and at 60-day follow-up. Furthermore, at follow-up, they were more likely to be living with someone who abused alcohol or used drugs (9% vs.7%). CONCLUSIONS: Although females comprised only 29% of the DUI treatment admissions, they were more impaired and experienced more problems than their male counterparts. The findings indicate that additional resources, including treatment for co-occurring mental health problems and living in sober households, may be keys to helping these women achieve abstinence and prevent additional DUI episodes.     

Trends in chemical hazards in Japan

In the past, the chemical industry in Japan has been the cause of a number of major industrial accidents. Subsequent to each accident, specific lessons have been learned. These lessons learned have been implemented in terms of safety education of the employees and/or safety measures of the equipment and facilities resulting in a rapid decrease of corresponding accident frequencies. In this paper, we summarized both recent and past major accidents caused by chemical substances in fixed installations in Japan. Case studies show that runaway reactions are among the main causes of major accident occurrences in the chemical process industry in Japan. A recent fatal poisoning accident caused by H₂S gas generated during maintenance work again highlights the necessity of adequate safety management in a chemical factory. Therefore, even if hazard evaluation of chemical substances and chemical processes is necessary to prevent runaway reactions, human error is also an important factor contributing to reaction hazards [Wakakura, M. (1997) Human factor in chemical accidents, J. Safety Eng. High Press. Gas. Safety Inst. Japan, 34, 846].     

Trends in occupational hygiene in Finland

The aim of this work is to evaluate and describe the current status of, and prospects for, the future of occupational hygiene in Finland. The main sources of information include a seminar held in the annual meeting of Finnish Occupational Hygiene Society and interviews with different stakeholders. Nanotechnology and other new materials, changing work environments, circular economy including green jobs, new medical methods and advances of construction methods were recognized as future challenges. Future work opportunities for occupational hygiene experts included exposure assessments in indoor air surveys, private consulting and entrepreneurship in general, international activities and product safety issues. Unclear topics needing more attention in the future were thought to be in new exposures, sensitive persons, combined effects, skin exposures and applicability of personal protective equipment. Occupational hygiene should broaden its view; occupational hygienists should have to cooperate with other specialists and grasp new challenges.     

Violence in the workplaces in Finland

The aim of this study was to describe violence in Finnish workplaces by comparing it with leisure-time violence. The data were derived from 13,762 interviews made from a representative sample of the Finnish population in 1988. The subjects were asked to report all the violent incidents they had encountered during the previous 12 months. There were 394 victims of violence in workplaces, that is, 40.6 victims per 1,000 workers. The rate of occupational violence was almost identical for males (40.6) and females (40.5). The most hazardous occupations were prison guard, police officer, and mental health nurse. The main reasons for violence at work were related to refusal of an authority's order to go away or to the relationship between doctor or nurse and patient. A typical assailant was an unaccompanied man who was under the influence of alcohol.

WTO与中国安全生产

新世纪之始,中国将要迈进世界贸易组织（ＷＴＯ）。在入世的过程中,与美国为首的发达国家之间始终存在着阻挠与反阻挠、限制与反限制的斗争,目前虽已告一段落,但远未结束。可以预见,中国加入ＷＴＯ之后,斗争非但不会停止,甚至可能会更复杂、更激烈。这场经济、贸易斗争实际上还有着深刻的政治与社会背景。最近几年,发达国家一直在努力使社会条款纳入世界经济贸易体系之中,在“关注发展中国家人权状况”的旗号下,反复提出“劳工标准”问题,即把本国安全生产问题与国际贸易挂钧。实际上这是“涂上绿色’”的贸易保护主义。中国是一…
