Road dust carries various contaminants and causes urban non-point source pollution in waterbodies through runoff. samples were collected each month two years then sieved into five particle size fractions. The concentrations of ten heavy metals (As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Zn, Fe) fraction measured. load index, coefficient divergence, Nemerow integrated risk index used to analyze the temporal variation ecological different advanced three-way model wavelet analysis quantitative identification time-series sources. Results showed that both most a decreasing trend from finest (P1) coarsest (P5). frequency P1 posing extreme was about times P5. Main types metal sources similar among fractions, whereas impact intensity these varied Traffic exhaust tended accumulate finer particles, its contribution Cu P5 only 35-55% other Construction contributed more coarser Pb increased 45.34% 65.35% Wavelet indicated traffic periodicities 5-8 10-13 months. Fuel combustion displayed strongest periodicity 12-15 months, peaking winter.

The present study aims to determine the concentrations and forms of Copper (Cu), Lead (Pb), Zinc (Zn), Chromium (Cr), Cadmium (Cd), Arsenic (As) in water sediments Xutuan mining area. geoaccumulation index (Igeo) ecological risk assessment coding (RAC) methods were used assess heavy metal pollution levels risks sediments. positive matrix factorization (PMF) model absolute principal component score-multiple linear regression (APCS-MLR) quantitatively analyze sources metals evaluated results showed good quality Cu, Cr, Zn, As mainly residual form, while Cd Pb organic matter combined form. Igeo RAC that degree higher APCS-MLR PMF models analyzed contributions natural (72.5% 25.1%) anthropogenic sources, respectively, further distinguished coal (26.4%), agricultural (21.44%), traffic (27.05%) sources.

In the current study, a total of 40 agricultural surface soil samples were collected from sites in Hamedan, Iran and contents As, Cd, Cr, Cu, Ni, Pb, Zn determined by ICP-OES. The average all analysed elements except Pb found to be greater than those background reported for Iran, which could presumably show anthropogenic sources these elements. EF PI values decreased order As > Cr Cu Cd Ni while, rank mean I-geo followed Pb. Additionally, cumulative RI with 175, demonstrated 'moderate ecological risk' across investigated area. results PCC, PCA, HCA showed that traffic activities regarded as most important factors affected content PTEs soils. conclusion, an accurate investigation on probability environmental risks due pollution other persistent organic pollutants (POPs) is recommended future works.
