NARAHA, Japan — Two years after the triple calamities of earthquake, tsunami and nuclear disaster ravaged Japan’s northeastern Pacific coast, debris containing asbestos, lead, PCBs — and perhaps most worrying — radioactive waste due to the crippled Fukushima Dai-Ichi nuclear plant looms as a threat for the region.
So far, disposal of debris from the disasters is turning out to have been anything but clean. Workers often lacking property oversight, training or proper equipment have dumped contaminated waste with scant regard for regulations or safety, as organized crime has infiltrated the cleanup process.
Researchers are only beginning to analyze environmental samples for potential health implications from the various toxins swirled in the petri dish of the disaster zone — including dioxins, benzene, cadmium and organic waste-related, said Shoji F. Nakayama of the government-affiliated National Institute for Environmental Studies.
Apart from some inflammatory reactions to some substances in the dust and debris, the longer-term health risks remain unclear, he said.
The mountains of rubble and piles of smashed cars and scooters scattered along the coast only hint at the scale of the debris removed so far from coastlines and river valleys stripped bare by the tsunami. To clear, sort and process the rubble — and a vastly larger amount of radiation-contaminated soil and other debris near the nuclear plant in Fukushima, the government is relying on big construction companies whose multi-layer subcontracting systems are infiltrated by criminal gangs, or yakuza.
In January, police arrested a senior member of Japan’s second-largest yakuza group, Sumiyoshi Kai, on suspicion of illegally dispatching three contract workers to Date, a city in Fukushima struggling with relatively high radioactive contamination, through another construction company and pocketing one-third of their pay.
He told interrogators he came up with the plot to “make money out of clean-up projects” because the daily pay for such government projects, at $160-$180, was far higher than for other construction jobs, said police spokesman Hiraku Hasumi.
