Ecological Risk Assessment and Source Contributions of Heavy Metals in the Sediment of the Chan Thnal Reservoir, Kampong Speu, Cambodia

Abstract: Metal contamination from farming, inadequate wastewater treatment, and poor disposal of municipal garbage are major threats to public health. This research aimed to (1) assess the extent of heavy metal contamination in sediment samples, (2) describe the distribution of heavy metals by locating likely pollution sources using a positive matrix factorization (PMF) model, and (3) quantify the potential ecological consequences associated with these metals at six different places around the Chan Thnal Reservoir. The… Show more

“…Similarly, woodland areas, despite being less intensively managed, may accumulate As due to the application of livestock manure and other organic fertilizers, which are common in sustainable forestry practices. Long-term agricultural activities and green management practices can lead to significant As buildup in the soil [42,43]. Sumiahadi and Acar's research [44] suggests that improper agricultural practices may elevate soil erosion rates.…”

“…Soil contamination by metal(loid)s is a serious global environmental problem [53], especially in rivers and agricultural lands that utilize water, which is directly related to human health. Soil contamination with metal(loid)s is caused by a variety of sources, including natural weathering [54,55], mining activities [56,57], industrial activities [58,59], civil engineering, construction activities [60,61], and increased traffic [61][62][63].…”
