Water quality evaluation and ecological-health risk assessment on trace elements in surface water of the northeastern Qinghai-Tibet Plateau

Ecotoxicology and Environmental Safety, Год журнала: 2022, Номер 241, С. 113775 - 113775

Опубликована: Июнь 15, 2022

The Qinghai-Tibet Plateau is a unique area with water sources for approximately 40 % of the population in world. Water resources and quality are closely associated ecological security human health. Fifty-one trace elements surface samples (n = 40) were measured, quality, health risks assessed. Trace showed significant variations different bodies study area. Concentrations minor relatively high saline salt lakes while those REEs varied from 0.05 to 33.62 μg/L an average value 3.80 μg/L. Nemerow pollution index (NP) values ranged 0.08 3.48, 0.36 rivers, fresh reservoir samples; heavy metal (HPI) 3.70 21.18, indicating that most within critical limit; evaluation (HEI) degree contamination (DC) indicated free status. (WQI) 96 belonged excellent status samples. More attention should be given Cr, Zn Hg according potential risk assessment. Hazard quotients residential children 30 sites exceed 1.0 maximal 10.97, suggesting non-carcinogenic U, Zr Cr ingestion pathway, U dermal pathway primary contributors total risk. Carcinogenic recreational receptors range 3.20 × 10-5-7.38 10-3 8.62 10-6-3.63 10-3, respectively. carcinogenic higher than target 1 10-4, As below results this provided information on protection management northeastern Plateau.

Abstract This paper presents the state and spatial distribution of surface sediment contamination 77 lakes in Poland by Cr, Ni, Cd, Pb, Zn, Cu. The analyzed were located within a network nature protection areas territory European Union (EU). Spatial heavy metals (HMs), factors favoring delivery/accumulation HMs sediments, pollution sources analyzed. results indicate lake sediments HMs, but potentially toxic effects are only found single lakes. Cr indicates predominant impacts point sources, while for impact non-point sources. analysis showed presence with very high values particular (hot spots) western part Poland, group 5 low Zn (cold was identified central Poland. Principal component that wetlands is factor limiting inflow to Also, lower concentrations catchments higher proportion national parks reserves. Higher Special Protection Areas designated under EU Birds Directive. positive matrix factorization four HMs. High their delivery from industrial, urbanized, agricultural areas. However, these overlap, which disturbs characteristic quantitative profiles assigned
