Dissolved and total dissolvable manganese concentrations at station TT045_19-10

Current values have been verified by comparison to the NASS-4 SRM and by DDDC/APDC extraction with GFAAS analysis.当前数值已通过两种方式完成验证：其一为与NASS-4标准参考物质（Standard Reference Material, SRM）进行比对，其二为采用二乙基二硫代氨基甲酸/吡咯烷二硫代氨基甲酸铵（DDDC/APDC）萃取后，结合石墨炉原子吸收光谱法（Graphite Furnace Atomic Absorption Spectrometry, GFAAS）开展分析。
