AB  - The present study aimed to determine persistent organic pollutants (POPs) and 
      contaminants of emerging concern in endangered angelshark and guitarfish species 
      from southeastern Brazil, and to investigate potential impacts of these compounds 
      on morphometric indexes. Pesticides of emerging concern, pharmaceutical and 
      personal care products (PPCPs), polycyclic aromatic hydrocarbons (PAHs), and 
      polybrominated diphenyl ethers (PBDEs) were determined in hepatic and muscular 
      tissues of Pseudobatos horkelii, P. percellens, Squatina guggenheim, and Zapteryx 
      brevirostris obtained from artisanal and industrial fisheries operating in 
      southeastern Brazil. Accumulation profiles and effects of contaminants on 
      condition factor and hepatosomatic index were investigated. No differences were 
      detected regarding species contaminant concentration, potentially due to 
      similarities in habits, occurrence and trophic position shared by guitarfishes 
      and angelsharks. Polycyclic aromatic hydrocarbons (23.2-495.3 ng g (-1)), and 
      PPCPs such as diclofenac (<LOQ - 448.4 ng g(-1)) and methylparaben (<LOQ - 
      645.5 ng g(-1)) presented the highest concentrations, regardless of the species. 
      Effects of elasmobranch size were not significant on contaminant levels, 
      indicating the lack of bioaccumulation over time. We suggest that the exposure to 
      contaminants in elasmobranchs inhabiting this region is highly dependent on the 
      economic activities and high urban development in southeastern Brazil. Regarding 
      potential impacts of such exposure, the condition factor was only negatively 
      influenced by PBDEs concentrations, whereas the hepatosomatic index was not 
      influenced by any contaminant. Despite this, our results indicate that 
      guitarfishes and angelsharks are exposed to POPs and contaminants of emerging 
      concern potentially toxic to aquatic organisms. In this context, more refined 
      biomarkers should be used to predict potential impacts of these contaminants on 
      elasmobranch's health.
