Abstract This study aims to assess the occurrence of arsenic in the intertidal sediments of River Scheldt in Belgium. Samples of the sediments were collected from eleven different locations along the River Scheldt up to 100 cm depth and analysed for physicochemical properties including arsenic contents. The study revealed that the arsenic contents in the sediment samples varied in a wide range, from 2.3 to 140.2 mg kg-1 dry weight. However, the arsenic concentrations were generally below the background concentrations and the remediation thresholds of arsenic in Flanders, Belgium. In addition, it is observed that a strong positive correlation exists between arsenic, organic matter and clay contents. On the contrary, negative correlation exists between arsenic, sand and pH. Based on the regression studies between organic matter and arsenic, it is recommended that proper management practices has to be developed that stops the increase in organic matter in the study areas.
