There are few bibliometric studies showing current technologies and their combinations for the remediation of contaminated soils. For this reason, a scientometric study was carried out in order to know the trends in soil contamination treatment technologies. The study considered original articles and reviews published in the Scopus and Web of Science databases between January 2010 and June 2021, evaluating: (a) characteristics of the publications, (b) main research sources, (c) citations and production by journals, (d) keywords used, (e) countries, institutions and authors active in research production, (f) most cited articles and (g) trends in soil treatment and remediation techniques. The results showed: (a) continuous growth of publications on soil remediation in the “Environmental Science” subject area and a limited contribution of the “Soil Science” and “Agriculture and Bi...

A total of 188,859 meteorological-PM10 data validated before (2019) and during the COVID-19 pandemic (2020) were used. In order to predict PM10 in two districts of South Lima in Peru, hourly, daily, monthly and seasonal variations of the data were analyzed. Principal Component Analysis (PCA) and linear/nonlinear modeling were applied. The results showed the highest annual average PM10 for San Juan de Mirafores (SJM) (PM10-SJM: 78.7 µg/m3) and the lowest in Santiago de Surco (SS) (PM10 -SS: 40.2 µg/m3). The PCA showed the infuence of relative humidity (RH)-atmospheric pressure (AP)temperature (T)/dew point (DP)-wind speed (WS)-wind direction (WD) combinations. Cool months with higher humidity and atmospheric instability decreased PM10 values in SJM and warm months increased it, favored by thermal inversion (TI). Dust resuspension, vehicular transport and stationary sources contributed m...
