By using the equipment designed and developed by ourselves, experiment of investigating the influence of dissolution on some geo-chemical parameters (such as δ13C,δD,and iC4/nC4 in water-dissolved gas (WDG) during migration) was performed. The result shows that, with the increase of distance, 1) the relative abundance of non-hydrocarbon (CO2) and hydrocarbon (CH4) increase while the relative abundance of hydrocarbon (C2+) decreases (the relative abundance of hydrocarbon (C5+) can be basically negligible); 2) the relative abundance of benzene and methylbenzene increase in the initial time and then decrease. The carbon and hydrogen isotopes of methane vary slightly, which can be regarded as indicators of gas dissolved in water formation. 展开更多

The accumulation of generated chemical wastes posed a serious problem for the UP College of Pharmacy. The faculty from the Department of Pharmaceutical Chemistry devised a scheme for the identification and segregation of the chemical wastes and created a system for proper disposal of future chemical wastes. There were a total of 1,142 of accumulated chemical waste bottles, 804 of which were subjected to identification and segregation procedures. The wastes were preliminarily tested for its solubility/miscibility in water and acidity or basicity. The identification was done by qualitative tests for cyanide, sulfide, halogenated, non-halogenated, oxidizing, nitro, and heavy metal compounds. The final segregation was based on the presence of the most hazardous component or on pH and water-miscibility. The Department then developed and implemented a scheme for the proper disposal of the chemical wastes generated in laboratory experiments done in the College. Laboratory experiments were also modified to use less toxic and less amounts of chemicals. 展开更多
