Effective communication about complex environmental issues: Perceived quality of information about carbon dioxide capture and storage (CCS) depends on stakeholder collaboration

This experimental research addresses the effectiveness of communication about complex environmental issues, depending on whether the same information is provided by multiple collaborating or by individual organizations (i.e., stakeholders). The information provided pertains to carbon dioxide capture and storage (CCS) technology, as an example of a complex environmental issue. In Studies 1 (N = 75) and 2 (N = 66) we found that participants perceived factual information from collaborating stakeholders to be of higher quality than when the same information was provided by individual stakeholders. As predicted, the expectation of diverse perspectives being represented in the collaborative information mediated this effect. In addition, in Study 3 (N = 79) the perceived dissimilarity of collaborating stakeholders was shown to be an important precondition for the collaboration effect observed in Studies 1 and 2. Finally, these studies indicate that occasional collaboration between different stakeholders does not necessarily harm the perceived credibility of each individual stakeholder.     

Relation between management's behavioural intentions toward the environment and environmental actions

Drawing on Ajzen's Theory of Planned Behaviour, this paper analyses whether there is a relation between management's behavioural intentions toward an environmental problem and the company's specific actions in this area, and also considers the impact of the company size on these actions. For the data, a questionnaire was sent to 184 managers employed in industrial companies located in Spain which belonged to the automobile industry. The empirical analysis produces positive and significant regression coefficients and provides support for the hypotheses proposed. Specifically, the results show that the environmental actions carried out in the company respond at least in part to management's behavioural intentions toward these issues and the size of the firm.

Will photosynthetic capacity of aspen trees acclimate after long-term exposure to elevated CO2 and O3?

Photosynthetic acclimation under elevated carbon dioxide (CO₂) and/or ozone (O₃) has been the topic of discussion in many papers recently. We examined whether or not aspen plants grown under elevated CO₂ and/or O₃ will acclimate after 11 years of exposure at the Aspen Face site in Rhinelander, WI, USA. We studied diurnal patterns of instantaneous photosynthetic measurements as well as A/C_i measurements monthly during the 2004-2008 growing seasons. Our results suggest that the responses of two aspen clones differing in O₃ sensitivity showed no evidence of photosynthetic and stomatal acclimation under either elevated CO₂, O₃ or CO₂ + O₃. Both clones 42E and 271 did not show photosynthetic nor stomatal acclimation under elevated CO₂ and O₃ after a decade of exposure. We found that the degree of increase or decrease in the photosynthesis and stomatal conductance varied significantly from day to day and from one season to another.     

珠江三角洲潮土和水稻土酸缓冲特性试验研究

珠江三角洲潮土和水稻土对不同种类的酸具有一定的缓冲性,不同种类的酸对不同类型土壤的酸化趋势不同。大旺水稻土对酸的敏感性强于龙山潮土,龙山潮土属于稍易受害的稍敏感土壤,大旺水稻土属于易受害的敏感土壤;同一土壤对酸的缓冲能力比对碱的缓冲能力强;不同种类的酸对土壤的敏感性不同,土壤对硝酸的敏感性强于对硫酸的敏感性;土壤加酸后酸缓冲曲线和土壤中铝释放曲线的交点可以作为衡量土壤对酸敏感性的指标,交点越低,敏感性越强;加酸后土壤中铝的释放可以用模型y=nx+k来预测。

高氯酸钾项目生产过程中的环境风险及防范措施

根据国家环保总局发布的"高污染、高环境风险"产品名录(2009年),无机盐产品高氯酸钾属于高环境风险的产品,其生产存在较大风险。高氯酸钾项目在生产过程中的环境风险主要来源于强酸、强碱、有毒有害、易燃易爆等原辅材料、产品,运输、贮存和使用过程产生的燃爆、泄漏、贮运风险以及工艺废气治理措施失效等环节。识别项目产生的环境风险主要包括爆炸风险、泄漏风险、危险化学品贮运风险及氯气直排风险,并从生产管理、生产工艺及贮运等方面提出相应的防范措施。
