Abstract
To protect the workers' health, we evaluated the hazards of gasoline which the large amounts of use and lack of information, and perform the risk assessment through the measurement of working environment. It is estimated the reproductive toxicity, and has germ cell mutagenicity class 1B, also IARC 2B, ACGIH A3 with carcinogenicity. With working environment, it is measured as below the TLV-TWA $900mg/m^3$. It is also calculated $0.3mg/m^3$ as carcinogenicity RfC (worker), $2.7mg/m^3$ as chronic inhalation toxicity RfC (worker), $2.7mg/m^3$ as developmental toxicity RfC (worker). From all of these results, it is calculated that the risks are 459, 51 and 51 as carcinogenicity, chronic inhalation toxicity and developmental toxicity, respectively. It is concluded that the risk of gasoline is evaluated over 1.
화학물질로부터 근로자의 건강보호를 위해 사용량이 많으나 작업환경 및 유해성 평가 자료가 부족한 gasoline에 대해 유해성(hazards)을 조사하고 국내 취급실태 및 일부 취급 사업장의 작업환경 측정을 통해 위해성(risk assessment)을 평가하였다. 연구결과 gasoline은 생식독성 추정 및 생식세포 변이원성 물질인 1B, 그리고 IARC Group 2B, ACGIH A3 물질이었다. 작업환경 측정결과는 TLV-TWA 기준 $900mg/m^3$미만이었으며, 유해성 평가결과 발암 $RfC_{(Worker)}$는 $0.3mg/m^3$, 만성흡입독성 $RfC_{(Worker)}$는 $2.7mg/m^3$, 발달독성 $RfC_{(Worker)}$는 $2.7mg/m^3$이었다. 그리고 위험도 평가에서 발암성은 459, 만성흡입독성은 51, 발달독성은 51이었으며, 이를 토대로 한 gasoline의 위험도는 1을 초과하는 물질로 평가되었다.
