River sand is widely employed in landscaping and gardening applications.

Sand and gravel have long been used as aggregate for construction of roads and building. Today, the demand for these materials continues to rise. In India, the main source of sand is from river flood plain sand mining, in-stream mining, coastal sand mining, paleo channel sand mining, and sand mining from agricultural fields.

Drying. Expressing MP results as dry weight (MP/g sediment) is recommended due to high variability in the water content of sediments collected at different locations on the river bank ( van Cauwenberghe et al., 2015 ). For sample processing, drying methods such as oven drying, air drying, and freeze-drying can be used.
