Dolomite contains high amount of heavy metals that contribute to pollution and acidity of Manila Bay, said a fisherfolk group that has looked into the impact of the dumping of white sand along the Manila Baywalk. The Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya) warned of even more drastic consequences that the people will face due to the sand that came from crushed dolomite boulders in Cebu. The Department of Environment and Natural Resources (DENR) has started to cover the 500-meter stretch of baywalk on Roxas Boulevard with white sand as part of its rehabilitation efforts in the area.
