The aim of this research is the application of the Method of Organizational Congruencies before and after the substitution of organic solvents with vegetable agents for the cleaning of an offset printing machine in order to assess the organizational changes. A solvent-free process is the goal of the Subsprint Project (Technology Transfer Program of the European Community). This, study shows how human and environmental health is improved by using vegetable agents, though this change may lead to some other organizational constraints such as an increase of tbe time needed, monotony, and repetitiveness of the technical actions involved. The authors underline that the knowledge of the impact of the new technology on health helps a better understanding of the resistance to the change and its further amelioration. 相似文献

High concentrations of copper and tributyltin, two biocides used in antifouling paints, are found in harbors. Efforts are necessary to reduce the adverse impact of biocides from antifouling paints, but little is known about the actual use of such material. I surveyed the operators of 435 boats berthed in San Diego Bay, to determine what paints and maintenance procedures were being used.More than 90% of the respondents used conventional leaching paints. These paints contain 40% to 65% copper compounds and 3% to 7% tributyltin compounds. Few respondents used copolymer paints. Those who did use copolymer paints seemed to repaint less frequently than those using conventional leaching paints.Professional maintenance companies do not initiate repainting as frequently as individuals doing their own maintenance.It appears that the input of antifouling biocides to harbor waters could be reduced by at least one-third simply by educating boat-owners about the chemical mechanisms involved in antifouling paints, by explaining the environmental and economic advantages of using slow-release paints, and by encouraging them not to repaint until their paint's useful life has expired. 相似文献

豆制品是中国的传统食品,在生产过程中产生高浓度废水,如果对高浓度有机废水进行预处理,采用回收蛋白质以及化学混凝处理方法可以大大降低废水浓度,一定程度上可以减轻后续处理的难度、降低处理成本。针对豆制品生产废水问题,对高浓度豆制品废水的预处理方法作了实验研究。采用调节等电点酸沉降的方法回收蛋白质,然后用聚合硫酸铁化学混凝处理上清液以降低COD的含量。实验证明了方法的可行性并得出了最佳实验条件。 相似文献

A knowledge transfer (KT) strategy was implemented by the IRSST, an occupational health and safety research institute established in Québec (Canada), to improve the prevention of psychological and musculoskeletal problems among 911 emergency call centre agents. An evaluability assessment was conducted in which each aspect of the KT approach was documented systematically to determine whether the strategy had the potential to be evaluated in terms of its impact on the targeted population. A review of the literature on KT in occupational health and safety and on the evaluation of such KT programmes, along with the development of a logic model based on documentary analysis and semi-structured interviews with key stakeholders, indicated that the KT strategy was likely to have had a positive impact in the 911 emergency call centre sector. Implications for future research are discussed. 相似文献

We conducted acute toxicity tests and sediment toxicity tests for copper pyrithione (CuPT) and a metal pyrithione degradation product, 2,2′-dipyridyldisulfide [(PS)2], using a marine polychaete Perinereis nuntia. The acute toxicity tests yielded 14-d LC50 concentrations for CuPT and (PS)2 of 0.06 mg L−1 and 7.9 mg L−1, respectively. Sediment toxicity tests resulted in 14-d LC50 concentrations for CuPT and (PS)2 of 1.1 mg kg−1 dry wt. and 14 mg kg−1 dry wt., respectively. In addition to mortality, sediment avoidance behavior and decreases in animal growth rate were observed; growth rate was the most susceptible endpoint in the sediment toxicity tests of both toxicants. Thus, we propose lowest observed effect concentrations of 0.3 mg kg−1 dry wt. and 0.2 mg kg−1 dry wt. for CuPT and (PS)2, respectively, and no observed effect concentrations of 0.1 mg kg−1 dry wt. for both CuPT and (PS)2. The difference in the toxicity values between CuPT and (PS)2 observed in the acute toxicity test was greater than the difference in these values in the sediment toxicity test, and we attribute this to (PS)2 being more hydrophilic than CuPT. In addition to the toxicity tests, we analyzed conjugation activity of several polychaete enzymes to the toxicants and marked activity of palmitoyl coenzyme-A:biocides acyltransferase and UDP-glucuronosyl transferase was observed. 相似文献

为了探讨在光催化分解水(下称光解水)制氢反应中含苯有机废水作为牺牲剂的可行性,以光沉积法制备了Pd/TiO2〔w(Pd)为0.5%〕模型催化剂,并且通过XRD(X射线衍射)、BET(N2物理吸附)、TEM(透射电镜)、XPS(X射线光电子能谱)和UV-vis DRS(紫外-可见漫反射吸收光谱)等表征手段考察了催化剂的微观结构及性质, 使用泊菲莱Labsolar-Ⅲ AG系统评价了苯甲酸、邻苯二甲酸、间苯三甲酸作为牺牲剂的光催化性能. 结果表明:引入的Pd以Pb0和Pb2+高度分散在TiO2基底表面,未改变TiO2的晶体结构;与TiO2相比,Pd/TiO2具有更大的比表面积、更小的孔径和更强的光吸收性能. 苯甲酸、邻苯二甲酸、间苯三甲酸光解水产氢速率分别为4.264、6.429和5.400 mmol/(g·h),分别为空白处理〔无牺牲剂,0.733 mmol/(g·h)〕的5.8、8.8、7.4倍. 依据乙酸和三氟乙酸的光解水产氢速率数据及结构特征,初步探讨了苯甲酸参与价带空穴氧化反应的机理,发现光解水产氢速率的大小与苯甲酸牺牲剂的还原性强弱、羧基个数以及空间位阻有关,表现为牺牲剂发生photo-Kolbe脱羧反应越容易、羰基数目越多、空间位阻越小,其光解水产氢速率越高. 未来应进一步探寻高效、稳定的模型牺牲剂,以应用于氢能源生产研究. 相似文献
