▶ Biogeochemical cycles 生化地质循环
·carbon 碳，methane 甲烷，nitrogen 氮，sulfur 硫，phosphorus 磷，oxygen 氧，mercury 汞（水银）

太古宙时期金元素的生化地质循环
·基础定义：
--Reservoir 容器：physically well defined sphere of a substance
--transport path 传播途径: the route by which a substance is transphered from ne reservoir to another
--Flux 流通量: the amount (mass) of substance transferred per unit of time, for carbon this will often be Gt/year
--Important cycles 重要的循环:Hg 汞, Au 金, Fe 铁, Ag 银

▶Carbon cycle 碳循环
--major component of biomass 生物质的主要成分
--Influence climate system primarily through affecting CO2 (gas) level (and methane CH4,) both of them are
green house gases 温室气体 ：absorb the infrared energy being emitted by earth 吸收地球发出的红外线能量
（而不是吸收太阳光 solar radiation）
--other cycle interacted with carbon cycle, N, P 氮循环，磷循环 since they influence organism; and O
because of photosynthesis 光合作用 and _______________________________呼吸作用

✔主要 reservoir
1. sedimentary carbon 沉积物中的碳：millions and millions years
2. marine dissolved carbon 海洋里面溶解的碳：1000-50000years or so
3. soil and surface sediments 土壤和沉积物：100-1000 years
4. atmosphere 大气：10-100years
5. living biomass 生物质：years

✔主要的 natural transport path and fluxes
1. photosynthesis and respiration 光合作用+呼吸作用
2. burial in soil/surface sediments 埋在表层和土壤沉积物里
3. flux to and from the ocean(solubility)流入/流出海洋，和溶解度有关
4. Dissolution/precipitation of the carbonate （CaCO3）溶解，凝固成碳酸钙
5. Long term burial in sediments/rocks 长久埋藏在沉积物和岩石中
6. Weathering of silicate rocks (利用 atmosphere 中的 CO2)把含有硅元素的岩石侵蚀
7. Release of CO2 from plate tectonic/ volcanic activities.从地质板块和火山活动中放出 CO2

✔Major human transport paths and fluxes 主要的人为排放途径
1． Burning of fosil fuels 化石燃料的燃烧
2． Land use changes 土地利用改变

▶甲烷循环 methane cycle


Notes：一开始，并不是 plants 使得整体 atmopshere 被 oxygenate，而是_________________________
蓝藻进行的光合作用使得地球大气的环境逐渐变成有氧.
▶氮循环 Nitrogen cycle
·N 元素的重要性：Protein，DNA 组成部分，大气中 78%是 N2
·重要的反应步骤：
1. Nitrogen _____________________固氮
Specialiszed bacteria convert N2 into biological usable forms of nitrogen (ammonia, NH3)
·Haber-Bosch process:nitrogen fixed in this manner now greatly exceeds nitrogen fixed naturaly 以这
种方式固定的氮现在大大超过了自然固定的氮.哈伯-博世是第一个使用高压进行化学反应的
工业化学工艺。 它在极高的压力和适度的高温下将空气中的氮与氢直接结合。

▶ Sulfur Cycle 硫循环---essential component of protein 蛋白质的基础成分之一
·major cloud forming agent in atmosphere 大气中云的主要成分之一
·Sulfate aerosol (SO4
2-) make cloud condensation nuclei (CCN). 硫酸盐气溶胶形成云凝结核。
·Affect climate 会影响气候
·Major component of acid rain – ________________________________________硫酸 (H2SO4)
·Like Carbon – on long time scale is important in controlling how much oxygen is in the atmosphere

▶Phosphorus cycle 磷循环
·no significant atmospheric component
·Phosphate 磷酸盐 used in DNA and ATP (chemistry energy)
·Phosphates move through the food chain 磷酸盐是通过食物链传递
·Land→Organism→ Organism→ land

▶Oxygen cycle 氧循环
·占据 20% of atmosphere
·Essential for oxygen respiring ogranisms (like us )对于有氧呼吸生物至关重要
·coupled strongly to the carbon cycle (but also to the sulfur cycle)
·Burning of fossil fuel 燃烧化石燃料需要氧气助燃
·same as respiration 呼吸作用：
·C6H12O6 （organic matter 有机物）+6O2 → 6CO2 + 6 H2O
·all of our estimated fossil reserved only require 1% of the oxygen 我们估计所有保留的化石只需要 1％
的氧气
