The Department of Environment and Natural Resources (DENR) has not found toxic chemicals on the dolomite sand from the Manila Bay beach nourishment project, based on the test results released by its Environmental Management Bureau (EMB) and Mines and Geosciences Bureau (MGB). EMB and MGB released on Wednesday evening the test results of the analyses conducted on the dolomite sand samples taken from the beach nourishment project on Sept. 18 to determine if they contain heavy metals that are harmful to health and marine life. Both bureaus conducted testing on the presence of iron, nickel, lead, and mercury; grain size analysis; acidity/alkalinity (pH) and specific metals using the Toxicity Characteristic Leaching Procedure (TCLP); and x-ray diffraction analysis.
