Principles Of Organic Chemistry By Sylianco
Lim-Sylianco received an associate degree for the pre-medicine program at Siliman University in 1947. However, she switched out of the Medicine track shortly after to pursue a bachelor's degree in chemistry, where she graduated as magna cum laude in 1949. Lim-Sylianco then pursued a master's in Chemistry at University of the Philippines in 1949. There, she worked as a research assistant until 1951 and later took on an instructor role until she graduated in 1953. After receiving a Fulbright scholarship, she went to the United States to pursue her doctoral studies in biochemistry and organic chemistry at the University of Iowa. She was a research assistant in the university's Department of Pediatrics from 1953 to 1955 and a research fellow in the Department of Biochemistry from 1955 to 1957.

Lim-Sylianco moved back to teach at the chemistry and biochemistry departments of the University of the Philippines in 1957. From 1970 to 1973, she served as a consultant for the National Institute of Science and Technology. Lim-Sylianco was a prolific researcher, making contributions to several fields such as environmental mutagens and anti-mutagens, biochemical nutrition, bioorganic mechanisms, and mutagenicity of Philippine medical plants (oftrilaurin, trilinolein, etc.). In 1989, she became a member of the International Advisory Committee on Anti-mutagens. She was also dedicated to chemical education and wrote textbooks on organic chemistry and molecular biochemistry that were adopted nationally. These include: Principle of Organic Chemistry, 5th ed., 1975; Modern Biochemistry, 1976; Monograph Series on Molecular Biochemistry: Nucleic Acids, Protein, Carbohydrates, Lipids, 1974; Laboratory Manual in Organic Chemistry, 1965; and Laboratory Manual in Biochemistry, 1961.

The chemistry of the reactions between chlorine and the organic materials present in water is complex and poorly understood; however, important factors include the type and concentrations of organic materials in the raw water, the chlorine reaction time, temperature and chlorination pH (Williams et al., 1998). Consequently, there is a great degree of variation in the measured concentrations of chloroform in drinking water. Some specific contributors to the spatial and temporal variations in concentrations have been identified. Concentrations of organic materials in the raw water vary from one region to another, although the levels are generally higher in surface water than in groundwater. The extent of formation of chloroform varies with different water treatment processes (e.g., chlorine-chloramine, chlorine-chlorine, ozone-chlorine). Concentrations of chloroform in chlorinated water in treatment plants and distribution systems are approximately twice as high during summer months as during winter months, as a consequence of the higher concentrations of the precursor organic materials in the raw water during the warmer period. Levels can increase as the chlorinated water moves from the water treatment plant through the distribution system (Williams et al., 1995). Further increases in concentrations of chloroform in water can occur in domestic hot water tanks (Benoit et al., 1997).
