The principles of precaution and sustainability require more consideration in the assessment of environmental risks posed by chemicals and genetically modified organisms. Instead of applying risk reduction measures when there are serious indications for damage, full scientific certainty is often waited for before taking action. The precautionary principle particularly should be applied in those cases in which the extent and probability of damage are uncertain, e.g. in the case of persistent chemicals which are additionally bioaccumulative or highly mobile. Based on these principles, environmental action targets for risks associated with GMOs and chemicals can be developed. Risk management not only includes statutory measures but also instruments designed to influence behaviour indirectly are important to achieve the goals. Particularly for risks of GMOs which provoke fear, risk communication is important. Some rules to which attention should be paid in communication with the public are presented. 相似文献

碱渣处理装置的现状与展望 总被引:4,自引:0,他引:4
张振铎 《石油化工环境保护》1998,(2):48-52
碱渣处理一直是困扰炼厂环境保护的一大难题。碱渣处理装置成为炼厂的主要恶臭污染源,亟需处理。为此,我们通过国内外技术交流,在文献调研基础上,提出了碱渣空气氧化预处理脱臭治理方案。该工艺成熟、简单、可靠,已用于国外一些炼厂,并可大大改善大气污染,提高回收副产品的质量。 相似文献

The Finnish approach that is starting from the basic human needs of food, housing, mobility and related lifestyles enables us to address the social dimension of sustainable development alongside the ecological and economic dimensions. In this context environmental problems cannot be resolved in isolation from people’s everyday lives, as can happen if environmental policies are based purely on emissions.But it is also worth questioning the potential for national SCP programmes in today’s global markets. Over the last ten years, domestic material flows within the Finnish economy have remained fairly constant, with gains in material efficiency cancelled out by increasing levels of material consumption. However, external material flows and the consequent environmental impacts have steadily increased, and the magnitude and environmental impacts of both imports and exports are approximately the same as for domestic flows. This means that the role of external material flows can no longer be ignored in national SCP policies.It is also important to integrate SCP with climate policies. Finland’s national climate and energy strategy is mainly based on the need to reduce CO2 emissions from energy production and industrial installations, but there is also a need for complementary actions to reduce the carbon footprints caused by private and public consumption. 相似文献
