A civic group in Seoul on Wednesday protested the use of dirt containing asbestos in ballparks and high school sports grounds.
The pro baseball season will continue despite the asbestos scare, officials at the Korea Baseball Organization say.
Earlier this week, environmental watchdogs reported that testing showed that dirt in five of the seven pro baseball stadiums contains higher-than-standard levels of asbestos.
Until they can rip the dirt out, groundkeepers will water the fields more often to reduce dust levels, the KBO said in a statement.
