日照石臼扇贝养殖水域夏季污染调查分析

１９９８年７月中旬，山东省日照市东港区石臼扇贝养殖区出现养殖的栉孔扇贝大面积死亡。死亡顺序由岸边开始向里面蔓延；死亡程序岸边大于里面，介体大的大于个体小的。为弄清扇贝死亡的原因，１９９８年８月，进行了该水域的环境综合调查。本文报道了污染环境的调查结果，ＣＯＤ平均值为０．９８％ｍｇ／Ｌ；石油类为６．２７ｕｇ／Ｌ；挥发酚为１．６９ｕｇ／Ｌ；悬浮物为１０．６４ｍｇ／Ｌ；Ｃｕ为６．４０ｕｇ／Ｌ；Ｚｎ为９；     

Carbon Offset Potentials of Four Alternative Forest Management Strategies in Canada: A Simulation Study

Using an Integrated TerrestrialEcosystem C-budget model (InTEC), we simulated thecarbon (C) offset potentials of four alternativeforest management strategies in Canada: afforestation,reforestation, nitrogen (N) fertilization, andsubstitution of fossil fuel with wood, under differentclimatic and disturbance scenarios. C offset potentialis defined as additional C uptake by forest ecosystemsor reduced fossil C emissions when a strategy isimplemented to the theoretical maximum possibleextent. The simulations provided the followingestimated gains from management: (1) Afforesting allthe estimated 7.2 Mha of marginal agricultural landand urban areas in 1999 would create an average Coffset potential of 8 Tg C y^-1 during 1999–2100,at a cost of 3.4 Tg fossil C emission in 1999. (2)Prompt reforestation of all forest lands disturbed inthe previous year during 1999–2100 would produce anaverage C offset potential of 57 Tg C y^-1 forthis period, at a cost of 1.33 Tg C y^-1. (3)Application of N fertilization (at the low rate of 5kg N ha^-1 y^-1) to the 125 Mha ofsemi-mature forest during 1999–2100 would create anaverage C offset of 58 Tg C y^-1 for this period,at a cost of 0.24 Tg C y^-1. (4) Increasingforest harvesting by 20% above current average ratesduring 1999–2100, and using the extra wood products tosubstitute for fossil energy would reduce averageemissions by 11 Tg C y^-1, at a cost of 0.54 TgC y^-1. If implemented to the maximum extent, thecombined C offset potential of all four strategieswould be 2–7 times the GHG emission reductionsprojected for the National Action Plan for ClimateChange (NAPCC) initiatives during 2000–2020, and anorder of magnitude larger than the projected increasein C uptake by Canada's agricultural soils due toimproved agricultural practices during 2000–2010.     

H/O生化处理系统中硫酸盐的转化规律

H／O（水解－好氧）生化处理工艺已在味精废水、柠檬酸废水、染料化工废水的治理中得到了应用，但其中硫酸根的影响是个不可忽视的问题。本文根据工程实践，着着研究SO4^2－在生化处理系统中的转化规律，以及研究克服其还原物－H2S对处理系统影响的工艺措施。     

滇池流域农村面源问题浅析

介绍了滇池流域自然和社会经济概况，分析了非点源污染的特性。认为滇池流域农村面源主要由村镇生活污水、农村固体废物、化肥施用、地表径流、土壤侵蚀和流失、畜禽养殖粪便构成。在得出结论的基础上提出了措施。
