Lead and chrome have been used as anticorrosive pigment starting with polychlorinated biphenyl (PCB) for anticorrosion painting of steel structutes commencing with bridge. With deterioration thereof, when carrying out a coated film peeling work, it is hoped to give consideration to appropriate waste disposal and surrounding environment, commencing with prevention of exposure to workers.

We make a related investigation starting with a toxic substance analysis such as these PCBs.

Purpose analysis method feature preliminary survey content test pretreatment: Compliant with "Measuring method related to low concentration PCB containing waste (second version)" (Ministry of the Environment on September in 2014). Measurement: Compliant with high resolution GC-MS method high-sensitive waste determination elution test "Detecting method of metal and so on contained in industrial wastes" (1973 Environment Agency Notification No.13)
