AB  - This study aims to evaluate the dynamics and their ecological risks for aquatic 
      species of lipid regulator, nervous stimulant, anti-inflammatory and endocrine 
      disrupters in an upflow anaerobic sludge blanket (UASB), submerged aerated 
      biological filters (SABF) and horizontal subsurface flow constructed wetland 
      (HSSF-CW) reactors that treat swine wastewater. Four organic loads of swine 
      wastewater (SW) were used according to changing the chemical oxygen demand. 13 
      contaminants were quantified, standing out the endocrine disruptors, lipid 
      regulator and anti-inflammatory. In phase III, 8318.4 ng L(-1) of 4-ocylphenol 
      was found at the influent of the UASB reactor and removal from 1877.1 to 
      13.7 ng L(-1) in the bisphenol A system. With the maximum organic load, there was 
      a reduction among all the treatment units, with concentrations between 1877.1 and 
      13.7 ng L(-1) of bisphenol A and had naproxen removal of 94.5% and 2,7 ng L(-1) 
      after treating phases II and III. It was found that 24.6% of the contaminants 
      presented a high ecological risk, with maximum values of 27.4 (4-nonylphenol, 
      phase II), 24.6 and 5.9 (17beta-estradiol, phase IV and I, respectively), 13.4 
      (4-ocylphenol, phase III) and 4.4 (estrone, phase IV) in the influent system. The 
      reduction of ecological risk potentials was optimized by SABF and HSSF-CW. The 
      effect oxygen availability and microbiological activities optimized the reduction 
      of ecological risks on zebrafish (Danio rerio) and cnidarian (Hydra attenuata) 
      species, moreover, the reduction of mass flows and ecological risks of the 
      emerging contaminants are associated with the use of biological reactors in 
      series and organic stabilizations.
