1.1. 광산현황
우리나라는 협소한 국토면적에 비하여 금, 은, 동, 철 등의 금속자원과 무연탄이 풍부하여 삼국시대이전부터 광산의 개발이 이루어져 왔으며, 특히 일제강점기에 자원수탈의 목적으로 수없이 많은 광산이 개발되었다. 특히 일제 강점기에는 전 국토에 걸쳐

우리나라 폐광산의 현실
광산은 광복 이후 우리나라의 산업화의 원동력이 되었다. 당시 우리 국민들은 중요한 삶의 터전으로서 광산을 선택하였다. 그러나 국민소득이 증가하면서 80년대 중ㆍ후반 대부분의 광산들이 자동 폐기되었다. 이에 따라 한때는 산업화의 원동력이

N losses In Agricultural Fields
Generally, studies for N losses has not considered DON but DIN in agricultural systems
Whereas DON has been regarded as a major component in N losses of nonagricultural systems
Albeit lack of knowledge on DON, The idea is growing that it's contribution on N losses might not be ignorable
soil had usually required treatment with lime and years of cultivation to neutralise excess acid and to develop fertility. Irrigation was generally not necessary, but drainage systems were often needed to remove excess water.
Until the late nineteenth century, Finland's isolation required that most farmers concentrate on producing grains to meet the country's basic food needs. In the fall, farme
soils. This greatly increases yields of agricultural crops, especially those that cannot obtain nitrogen from the atmosphere. The ammonia is converted to nitric acid, an essential ingredient in explosives, via the Ostwald-Bauer process invented by German chemist Wilhelm Ostwald (1853-1932) in 1901. During World War I, synthetic ammonia was used to manufacture ammunition after Germany's nitrate su

1) principle
Soil vapor extraction, also known as soil
venting or vacuum extraction, is a cleanup
technology commonly used to remove
VOCs in vapor from contaminated property.

Contaminant : VOCs
Place : gas station base, industrial base,
military base
