An effective method, use of a 2,4-dinitrophenylhydrazine (DNPH) derivatization and high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection, has been used for separation carbonyl compounds. In particular, acetonitrile/water composition as a mobile phase could not separated acrolein/acetone and 2-butanone/ butyraldehyde. In this study, however, that"s compounds separated using acetonitrile/water/tetrahydrofuran as a mobile phase. The resolution was 1.48 and 1.46, respectively. Also, aldehydes and ketones was shown different decrease rate and increase resolution at increase tetrahydrofuran ratio. But butyraldehyde become coeluted methacrolein.
Therefore, it is need to consider of mobile phase for separation of butyraldehyde.

In this study, the emission characteristics of landfill gas (LFG) were investigated with respect to reduced sulfur compounds (RSC) and elemental mercury. To describe their emission characteristics accurately, methane and dilution-to-threshold (D/T) ratio were also analyzed as reference. LFG samples were collected in three different pathways; (1) old landfill (LF), (2) new LF, and (3) composite from both LFs. Differences in RSC concentrations between two LFG samples were relatively insignificant in the case of H2S, CS2, and SO2. On the other hand, a significant reduction in CH3SH and DMS concentrations was observed from old landfill. The concentration data of Hg and methane showed a similar spatial trend between new and old LF, as seen from RSC. In general, a large quantity of trace gas pollutants came out from new rather than old LF. The correlation analysis indicated strong relationship between most sulfur compounds, while it is not for other components including Hg, CH4, and D/T ratio. It suggests that trace composition of LFG comply well with the maturity of landfill.

Recently, odor and white smoke emitted from textile industry has emerged as a social problem. Most of pollutants from textile industry is due to the emissions from tenter facility, and in many case wet scrubber is widely used for treating this waste gas from tenter facility. However, it is still difficult to improve the environment of textile complex because of low treatment efficiency. For this reason, we carried out the EFC (Electric Fume Collector) pilot test (50 CMM) for removing odorous substances from waste gas emitted from tenter facility. EFC is a kind of wet electrostatic precipitator. As a result of this study, pollutants and white smoke were eliminated effectively and quite large amounts of oil could be recovered.

The civil consciousness for reducing odor by increasing the flow rate with the Gulpo river which has been played a major water course in Incheon area were investigated with the survey of odor related questions for the citizens neighboring the river. The citizens suferred from odors generated from the river and factories has shown that the increase of the flow rate had good effect for reducing odors from the results of survey.

Odors were produced in the reactor where contained the swine excreta sampled from the pigery and were analyzed the major odor materials based on the odor contribution index. The container hoggery where six pens were separated was set up in S-myun, Gyeonggi-do, Korea: one was control group, the other were experimental group. Sixty weaners were raised and their excreta were sampled every week to the test of the effect of feed type probiotics. Some probiotics showed very effective deodorizing activity during the whole experimental periods. All products had positive effects on the reducing odor intensities after 4 to 5 week periods. The odor contribution analysis represented the main odor compounds were trimethylamine and volatile sulfur compounds such as hydrogen sulfide, mercaptane, and dimethyl sulfide.

MIt is important to estimate odor impact from the emission sources located in the industrial complex to near-by residential area. To understand modeling capacity in describing the odor dispersion, we examined an accuracy of odor modeling comparing with concentric measurements of sensory odors from the industrial complex. The odor measurements were carried out 6 times at 10 sites along the concentric circles and they were compared with odor modeling results using CALMET and CALPUFF. Although there are some discrepancies between the modeled and measured odor intensities, the model could depict key characteristics of odor dispersion patterns.
The uncertainties in emission data and meteorology were main causes of the discrepancies. The odor modeling procedure developed in this study can be used in odor forecasting system and odor impact assessment. In order to improve the accuracy of odor modeling, the improvement of odor emission data and systematic monitoring of the odor using sensor network are necessary in future.
