TAILIEUCHUNG - Measurements of heavy metals and natural radioactivity levels in water, soil and vegetation around the titanium mining site in Phu Cat district, Binh Dinh province

This study was formulated specifically to provide data of radioactivity of soils, waters and vegetation from two regions: Cat Thanh and Cat Lam in Phu Cat District which earmarked for Titanium mining project. The field survey was done at the beginning of the study. | Nguyễn Thị Thúy Hằng và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 139(09): 121 - 124 MEASUREMENTS OF HEAVY METALS AND NATURAL RADIOACTIVITY LEVELS IN WATER, SOIL AND VEGETATION AROUND THE TITANIUM MINING SITE IN PHU CAT DISTRICT, BINH DINH PROVINCE Nguyen Thi Thuy Hang*, Dang Vu Xuan Huyen, Lai Duy Phuong, Trinh Thi Bich Huyen, Dang Vu Bich Hanh Ho Chi Minh City University of Technology SUMMARY This study was formulated specifically to provide data of radioactivity of soils, waters and vegetation from two regions: Cat Thanh and Cat Lam in Phu Cat District which earmarked for Titanium mining project. The field survey was done at the beginning of the study. Groundwater samples from 30 wells or boreholes in mining (n = 6) and non-mining areas (controls, n =24), 15 soil samples and 15 vegetation samples were collected. Then, they were analyzed to examine the relationship between community health and characteristics (pH, electrical conductivity, turbidity, total dissolved solids, sulfates, hardness, As, Cd, Fe, Mn, Pb, As, alpha, beta, and gamma radiation). A total number of thirty samples were analyzed for heavy metals using ICP/MS method. Radioactivity levels of the samples were determined using a high purity germanium (HPGe) detector. The results show that there is some points should be considered about radioactivity level in the mining area. Some water samples are detected to contain high concentration of arsenic and disease incidence nearby titanium mines is higher than other areas. Base on the study results, this paper will recommend the solutions to protect community health. Key words: Heavy metals, titanium mining, community health, natural radioactivity INTRODUCTION* Most titanium mines are located in coastal communes of the two districts Phu My and Phu Cat, and in a part of the Nhon Hoi economic zone, situated in the provincial capital Quy Nhon City. Over 30 enterprises have been granted licenses for titanium exploitation, with a registered capacity of up to 650 .
