Seasonal and spatial variability of PM2.5 concentration, and associated metal(loid) content in the Toluca Valley, Mexico.

Data
base of season and site sampling in Toluca Valley, Mexico. We reported the wind
roses parameters, temperature, humity relative, PM2.5 concentration and metal
and metalloids content. . The objective of this study was to provide evidence of the
seasonal and spatial variation of metal(lloid)s in particulate matter minor to
2.5 microns (PM2.5) in Toluca Valley. Four sites were sampled between
2013-2014, that include urban and industrial areas, in the dry-cold
(November-February) and hot-dry (March-May) season; PM2.5 were collected
using high and medium volume samplers. Metal and metalloids concentrations in
PM2.5 were analyzed using Inductively Coupled Plasma Mass Spectrometry
(ICP-MS).
