Purpose: The purpose of this study was to investigate if companies' efforts of environmental management practices have positive effect on the companies' performance in the first stage of study. In the second stage, we tried to confirm whether the degree of companies' making efforts on cost leadership strategy and quality leadership strategy function as moderate variable on relationship between environmental management practices and performance. Methods: The collected data through survey were analysed using multiple regression model in the first stage of the study and moderate regression model in the second. Results: The results of this study are as follows; environmental management practices have positive effect on corporate performance. Moreover, much effort on quality leadership strategy has limited significant moderate effect on relationship between environmental management practices and performance, while much effort by companies on cost leadership strategy does not have significant moderate effect on the relationship between the two variables. Conclusion: Manufacturing and services companies in Korea need to make effort for environmental management practices to improve corporate performance. Moreover, if that efforts are combined with quality leadership strategy, they can expect synergy effect with environmental management practices for performance improvement.

We were carried out to monitor pesticide residues in herbal medicine. In Korea Pharmacy, these are no critics for pesticides except 5 kinds of organic chlorines (BHC, DDT, Aldrin, Endrin, Dieldrin) and heavy metals. We analysed 53 kinds of pesticides consisted of 14 kinds of organochlorines, 20 kinds of organophosphoruses, and 19 kinds of pesticides estimated endocrine disruptor on 373 samples consisted with 30kinds of herbal medicine. In this study, Domestic, Chinese and Japanese herbal medicines were tested with GC/ECD, GC/NPD and then confirmed with GC/MSD. Recoveries were 75$\sim$l10% in ECD detector and 76$\sim$97% in NPD detector. Detection limits were 0.004$\sim$0.064ppm in ECD detector and 0.006$\sim$0.094ppm in NPD detector. Organochlorines and others were not detected in samples.

2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin(TCDD), a prototype of many halogenated aromatic hydrocarbons, is a ubiquitous, persistent environmental contaminant and the most powerful carcinogen categorized by IARC. Despite extensive research, the mechanisms of TCDD-induced carcinogenesis are poorly understood, and its carcinogenic potential in human is not clear.(omitted)

There has been many findings of natural, environmental or manufactered nonsteroidal substances shown to have estrogenic activity. Since estrogens affect reproduction and cellular development to cause disease in people or animals, chronic exposure may have a major impact on health.(omitted)

Among the environmental toxic metals, cadmium and lead compounds are very hazard for human health because these may affect the biological function of human body and furthermore enhance the cause of various disease. In recent years, as the view of environmental toxicology, the combination of toxic metals suffering human health is especially significant cadmium chloride (10 mg/kg P. 0., 1 mg/kg I.P.) and lead acetate (20 mg/kg P.O., 2 mg/kg I.P.) were administered to rats for 4 weeks on alternate days and then examined the effect of these on body weight, tissue weight and also biochemical function in blood and tissue were investigated and comparision of the two experimental groups such as single and combined administration. According to the results of this experiment, accumulation of heavy metals increased and biological metabolic function grew worse but, in tissue, toxic effect decreased by combined administration and intraperitoneal administration was more toxic than per OS.

This study was investigated the residual contents of sulfur dioxide on the 373 kinds of herbal medicine distributed from Korea, China, and Japan. A modified Monier-Williams method was described for the determination of $SO_{2}$ contents in herbal medicines. The residual contents of $SO_{2}$ were not detected at 221 products$(59.8{\%})$ in total 373 products. Regardless of region, $SO_{2}$ contents were not found at Farfarae Flos, Zizyphi Spinosi Semen, Castanea crenata, and Strychni Ignatii Semen. But it's found at Asparagi Radix, Codonopsitis Radix, Lilii Bulbus, and Kaempferiae Rhizoma of every region collected the samples. Also, $SO_{2}$ contents were not detected at the herbal medicines which collected cultural fields of dometic. $SO_{2}$ contents ranged 11$\~$3990 mg/kg(mean 152 mg/kg) at domestic samples, 11$\~$3440 mg/kg(mean 603 mg/kg) at imported samples. After treated with water wash and hot water extraction, the reduction rates of sulfur dioxide were appeared with $24.4{\%}\~68.7{\%}\;and\;83.8{\%}\~100.0{\%},$ respectively. These data will be used to establish a criteron of residual sulfur dioxide in herbal medicines.
