As the use of wood pellets increases, there is an increasing interest in the safety of the wood pellets themselves to avoid physical and chemical damage to people and the environment. This study investigated the contents of nitrogen, sulfur, chlorine, arsenic, cadmium, chromium, copper, lead, mercury, nickel, zinc, and cesium in wood pellets distributed in Korea as a preliminary survey for establishing safety evaluation standards for wood pellets. Nitrogen, sulfur, chlorine, and heavy metal contents of wood pellets produced in Korea met the specification for the 1st grade of wood pellets determined by the National Institute of Forest Science and the specification for the commercial and residential wood pellets of A1 grade determined by the ISO and the evaluation standards for wood pellet safety determined by the Korean Forest Service. However, among imported wood pellets, some wood pellets contained nitrogen, sulfur, chlorine, and heavy metal exceeding the safety evaluation standards. Cesium radioactivity was not detected in domestic wood pellets. Cesium radioactivity was detected from wood pellets imported from Japan, but it was below the limits specified in the wood pellet safety evaluation standards. In conclusion, by establishing safety standards for wood pellets, we believe that safe wood pellets will be used.

목재펠릿 사용량이 증가함에 따라 사용하는 사람과 환경에 물리적 화학적 피해가 발생하지 않도록 목재펠릿 자체의 안전성에 대한 관심이 증가하고 있다. 본 연구는 목재펠릿의 안전성평가 기준 제정을 위한 예비조사로서, 국내에서 유통 중인 목재펠릿의 질소, 황, 염소, 비소, 카드뮴, 크롬, 구리, 납, 수은, 니켈, 아연, 세슘방사능의 함유량을 조사하였다. 국내산 목재펠릿의 질소, 황, 염소 및 중금속 함유량은 국립산림과학원의 목재펠릿 품질 1급 기준과 ISO의 비산업용 목재펠릿 A1급 기준 및 목재펠릿 안전성 평가기준을 만족하였다. 그러나 수입 목재펠릿의 경우 일부 목재펠릿의 질소, 황, 염소 및 중금속 함유량이 안전성 평가기준의 허용량을 초과하였다. 국내산 목재펠릿에서는 세슘방사능이 검출되지 않았다. 일본으로부터 수입된 목재펠릿으로부터는 세슘방사능이 검출되었으나, 목재펠릿 안전성평가 기준에 규정된 허용량을 하회하였다. 결론적으로 목재펠릿 안전성 평가기준 설정은 안전한 목재펠릿 이용에 기여할 것으로 판단된다.
