“…The activities in this industrial complex could be important potential sources of discharge of trace elements to marine ecosystem. Several studies on contamination of soils has been conducted in this area (Chiang, 1985;González and Berqvist, 1986;González and Ite, 1992;Ginocchio, 2000Ginocchio, , 2004Parra et al, 2014) but a systematic study on the level of trace element contamination in marine sediments along the Quintero Bay has not been carried out.…”

“…The Los Maitenes wetland is subject to the local wind patterns determined by the contrast between the Quintero bay, and inland along an west‐east direction. The combined effect of source‐proximity and wind direction has been systematically indicated as the main driver for spatial variations in the content of elements in local rainfalls (Cereceda‐Balic et al., 2020), vegetation (Gorena et al., 2020) and topsoils (De Gregori et al., 2003; Parra et al., 2014b; Salmani‐Ghabeshi et al., 2015; Tapia‐Gatica et al., 2020). Indeed, independent geostatistical models (González et al., 2014; Tapia‐Gatica et al., 2020; Tume et al., 2019) consistently reproduce lower concentrations of metals around the northern tip of the Quintero bay and higher concentrations in sites proximal to VIA (e.g., La Greda and Los Maitenes towns, Figure 1a).…”

“…There has been much research on the pollution status, distribution, risk assessment and source of heavy metals in soil [10][11][12]. Some methods have been suggested to evaluate heavy metal pollution level, such as pollution index (PI), geo-accumulation index (I geo ) contamination factor (CF), Nemerow integrated pollution index (NIPI), and pollution load index (PLI) [4,[13][14][15][16].…”

“…Source identification is mainly used to qualitatively determine the source of pollutants, such as correlation analysis, cluster analysis, PCA and other methods [22,25]. Source apportionment can not only determine the main pollution sources, but also quantify the contribution of pollution sources [10]. At present, the most common source-apportionment methods for heavy metals include the chemical mass balance (CMB) model [26], positive matrix factor (PMF) model [27], UNMIX model [28], the absolute principle-component scores multiple linear regression (APCS-MLR) model [29], etc.…”
