Implications of depositional environment on the iodine enrichment in the sedimentary system: evidences from the N-alkane in sediments

To understand the implications of depositional environment on the enrichment of iodine in sediments, the N-alkane analysis has been conducted on the sediment from the North China Plain (NCP). The iodine contents of sediments ranged from 0.03 to 2.54 μg/g with the highest content occurring in the dep...
