The measurement of eight petrochemical factories indicates potential leaks in four factories. Of the eight fenceline screening lines, three factories are found to exceed fenceline permissible levels. The factories are requested to propose pollution reduction plans to EPA, and to conduct consequent pollution reduction measures. Totally there are 331 metric tons of VOC being reduced, and economic returns reach NTD$5,050,000 in 2005. The measurement of five wastewater treatment plants shows that instream water contains a variety of chemical compounds, such as 2-butanone, vinyl chloride, acetone, 1,2-dichloroethane, 1,3-butadiene, styrene, ethylbenzene, methyl acetate…etc. The uncovered unit reveals higher emission strength than covered unit. The average emission strength is 0.0026 kg/m3 which is similar to the previous investigations conducted by two other universities. Acetone is found to be the predominant compound in instream wastewater among LCD, DRAM, and Biotech factories. The wastewater treatment units of LCD factories have the highest VOC removal rates above 99%. There are four tasks of emergency measurements performed in this year. The OP-FTIR test method was legalized in November 2005, and was coded with NIEA A002.10C.
