Abstract:
Objectives To determine the contents of heavy metals lead, cadmium, mercury, arsenic, and chromium in water and sediment samples from Luoyang River in Quanzhou City, Fujian Province, and to understand the temporal and spatial distribution of heavy metal pollutants. Methods In 2018, 231 water and sediment samples were collected from 43 sampling points in 6 representative areas in Luoyang River during normal, rainy and dry seasons. The presence of heavy metals in the samples was then determined. Results Pb, Cd, Hg, As and Cr6+ were not detected in the water samples. Pb, Cd, Hg, As and Cr were detected in the sediments were 10.33,0.33,0.029,5.18 and 23.3 mg/kg , but the contents were low. Conclusion The water and sediments of Luoyang River in 2018 had good quality, both of which met Class I standards according to the environmental quality standards for surface water and for marine sediment quality, respectively.
