AB  - The persistent organic pollutants (POPs) due to their physicochemical properties 
      can be widely spread all over the globe; as such they represent a serious threat 
      to both humans and wildlife. According to Stockholm convention out of 24 
      officially recognized POPs, 16 are pesticides. The atmospheric life times of 
      pesticides, up to now were estimated based on their gas-phase reactivity. It has 
      been only speculated that sorption to aerosol particles may increase 
      significantly the half-lives of pesticides in the atmosphere. The results 
      presented here challenge the current view of the half-lives of pesticides in the 
      lower boundary layer of the atmosphere and their impact on air quality and human 
      health. We demonstrate that semivolatile pesticides which are mostly adsorbed on 
      atmospheric aerosol particles are very persistent with respect to the highly 
      reactive hydroxyl radicals (OH) that is the self-cleaning agent of the 
      atmosphere. The half-lives in particulate phase of difenoconazole, tetraconazole, 
      fipronil, oxadiazon, deltamethrin, cyprodinil, permethrin, and pendimethalin are 
      in order of several days and even higher than one month, implying that these 
      pesticides can be transported over long distances, reaching the remote regions 
      all over the world; hence these pesticides shall be further evaluated prior to be 
      confirmed as POPs.
