AB  - Surface soils from Guiyu, China (an intense e-waste processing center) were 
      analyzed for persistent organic pollutants (POPs) and variations in composition 
      of the resident bacterial communities. Denaturing Gradient Gel Electrophoresis 
      analysis of bacterial 16S rRNA gene showed that e-waste pollution altered the 
      bacterial community structure by promoting changes in species composition and 
      species richness. Bacterial diversity was not decreased at e-waste open-burning 
      sites, compared with a non e-waste site (reservoir site), due to flourishing of 
      possible POPs-consuming bacterial cohorts. PAH-incubated experiments confirmed 
      that different levels of PAHs might affect the bacterial community by suppressing 
      or favoring certain groups of bacteria, for instance, uncultured Clostridium sp. 
      and Massilia sp., respectively. Taxonomic analysis indicated beta-proteobacteria 
      and Firmicutes were abundant bacterial lineages in PAH-polluted soils. This study 
      is the first reporting bacterial community structures at e-waste processing 
      sites, and indicated that crude processing of e-waste has become a biohazard to 
      the terrestrial environment warranting more extensive studies of microbial 
      communities at e-waste polluted environments.
