Abstract
PDF - OBJECTIVES
Particulate contaminants, such as total and respirable dusts, can harm the health of farm workers via several routes. The principal aims of this field study were to determine the concentrations and emissions of particulate contaminants: total and respirable dusts, in the different types of swine houses used in Korea, and allow objective comparison between Korea and the other countries in terms of swine housing types. METHODS: The swine houses investigated in this research were selected with respect to three criteria: the manure removal system, ventilation mode and growth stage of pigs. Measurements of total and respirable dust concentrations and emissions in the swine houses were carried out on 5 housing types at 15 different farm sites per housing type. The swine houses investigated were randomly selected from farms situated within the central districts in Korea: province of Kyung-gi, Chung-buk and Chung-nam. RESULTS: The total and respirable dust concentrations in the swine houses averaged 1.88 and 0.64 mg/m3, ranging from 0.53 to 4.37 mg/m3 and from 0.18 to 1.68 mg/m3, respectively. The highest concentrations of total and respirable dusts were found in the swine houses with deep-litter bed systems: 2.94 mg/m3 and 1.14 mg/m3, while the lowest concentrations were found in the naturally ventilated buildings with slats: 0.83 mg/m3 and 0.24 mg/m3, respectively (p< 0.05). All the swine houses investigated did not exceed the threshold limit values (TLVs) for total (10 mg/m3) and respirable (2.5 mg/m3) dusts. The mean emissions of total and respirable dusts, per pig (75 kg in terms of live weight) and area (m2), from the swine houses were 97.33 and 9.55 mg/h/pig and 37.14 and 12.83 mg/h/m2, respectively. The swine houses with deep-litter bed systems showed the highest emissions of total and respirable dusts (p< 0.05). However, the emissions of total and respirable dusts from the other swine houses were not significantly different (p> 0.05). CONCLUSION: The concentrations and emissions of total and respirable dusts were relatively higher in the swine houses managed with deep-litter bed systems and ventilated naturally of the different swine housing types tested. In further research, more farms than the number used in this research should be investigated, which will present objective and accurate data on the concentrations and emissions of total and respirable dusts in Korean swine houses. In addition, personal sampling should be performed to objectively assess the exposure level of farm workers to particulate contaminants. -

- PURPOSE
To investigate the association between the type of preferred alcoholic beverage and drinking pattern and health characteristics. METHODS: A Cross-sectional study was conducted from 22 April to 3 May in 2002. 301 females and 699 males aged 13 to 59 were personally interviewed. Data on sociodemographic characteristics, drinking pattern and health characteristics were collected. 735 drinkers who were 19 year-old or over were included in analysis. Beverage preference was classified 3 categories: Beer drinker, wine drinker (including wine, makguly, chungju and yakju) and soju drinker (including soju and spirits). RESULTS: Beer drinkers were likely to be females. Compared to wine or soju drinkers, beer drinkers were less frequently drank, and consumed less total alcohol per week and less alcohol per 1 drinking among both male and female. Controlling for various confounders, beer drinker had significantly less total alcohol consumption per week, and alcohol consumption per 1 drinking than wine and soju drinker. CONCLUSION: Beer drinking were associated with less smoking in males and healthy drinking pattern in both gender than soju drinking. -
