Dissolved and total dissolvable manganese concentrations at station TT045_28-38

Current values have been verified by comparison to the NASS-4 SRM and by DDDC/APDC extraction with GFAAS analysis.当前数值已通过与NASS-4标准参考物质（NASS-4 SRM）比对，以及采用二乙基二硫代氨基甲酸钠/吡咯烷二硫代氨基甲酸铵（DDDC/APDC）萃取结合石墨炉原子吸收光谱法（GFAAS）分析的方式完成验证。
