Data on fate and distribution of organophosphate esters in the soil - sediments from Kathmandu Valley, Nepal

Globally, soil and sediments are known as the likely sinks of various organic pollutants, such as organophosphate esters (OPEs). However, the fate of OPEs in soil/sediment matrices is limited in the whole of South Asia, especially if there should be an occurrence of Nepal. This data article elucidates the fate and distribution of OPEs in soil and sediment samples from the capital city of Nepal (Kathmandu). A total of eight different compounds of OPE was measured in soil (N = 19) and sediment (N = 20) samples collected during October 2014. The median concentration and composition of the individual OPE have been discussed. Additionally, health risk exposure due to ingestion and dermal contact of OPE was assessed to mark the endanger of OPE. Moreover, risk quotient (RQ) for fish, Daphnia, and algae was calculated to forecast the risk of OPEs on aquatic organisms.
