최근 들어 기후변화로 인한 태풍의 강도는 강력해졌다. 광산지역의 광미와 폐석은 수해로 인해 환경에 악영향을 미쳤을 것으로 추정된다. 강릉지역은 3,693호(1936), 루사(2002), 매미(2003), 메기(2004) 등의 국내 최대 태풍의 영향은 받았다. 이번 연구는 태풍으로 인한 수해 이후 하천을 따라 그 주변에 높은 농도의 비소가 검출된 사례를 기초로 하였 다. 환경피해 관련 법은 오염 원인자의 책임을 명확히 하고 있지만, 잠재적인 자연재해 지역에서는 세심한 적용이 필요 하다. 이러한 지역에서 자연재해의 영향을 최소화하기 위해서 관련 법들의 개선과 연계가 필요하다. 이 연구가 하류 지 역에서 혼재된 오염물질 대응에 도움이 되길 기대한다.

A survey on the indoor air quality of schools was conducted on a total of 10 schools in each location, such as industrial zones, roadside zones and clean zones of the Jeonbuk Province. Regardless of their location, 75% of the schools were not suitable to the environmental standard, and five schools were inadequate in both the first and the second half measurement results. Compared to the public facilities survey conducted by the Jeollabukdo Institute Health and Environment Research from 2008 to 2016, the concentration of CO2, total airborne bacteria (TAB), and PM10, with the exception of HCHO, was higher in school classrooms than in any other public facilities. The correlations between pollutants and test items demonstrated that total airborne bacteria (TAB) were significantly correlated with the degree of ventilation, and the PM10 was correlated with the cleaning status, respectively. Although the other test items of indoor air quality in the school were measured in the same way as the public facilities measurement methods, the PM10 is applied in accordance with the simplified method. In order to investigate the difference between the measurement methods, the results were compared at the same point at the same time. When comparing the concentrations of PM10, the gravimetric method, which is a public facilities measurement method, showed a significant difference from the light scattering method, which is a method of measuring PM10 in schools. By comparison, it was confirmed that the light scattering method was measured lower than the gravimetric method. The light scattering method is useful for confirming the change of the particulate matter, but it is considered difficult to judge the concentration of the particulate matter in the classroom by the instantaneous measurement because of the potential error caused by high humidity, etc. Secondary pollution ions were measured at 17.1% ~ 40.5% in the industrial zone schools, 7.4%~27.4% in the roadside zone schools and 8.1%~21.8% in the clean zone schools, The percentage of pollution ions were not clearly distinguished by location.
