Highway toll collectors wear gas masks
Highway toll collectors at a toll booth on the freeway that passes through Yanling county in Hunan province have to wear gas masks because the booth is less than 200 meters from two polluting plants, one producing silicon and the other producing manganese. The heavy smoke released by the two plants smell like rotten eggs. The toll booth was opened in December of 2013. The county authorities have issued orders to the plants to clean up their act by December 30, 2014.
