Persian Gulf coral reefs are unique biota communities in the global sunbelts in being able to survive in multiple stressful fields during summertime (>36 °C). Despite the high-growth emerging health-hazard microplastic additive type of contaminants, its biological interactions with coral-algal symbiosis and/or its synergistic effects linked to solar-bleaching events remain unknown. This study investigated the bioaccumulation patterns of polybrominated diphenyl ether (PBDE) and phthalate ester (PAE) pollutants in six genera of living/bleached corals in Larak Island, Persian Gulf, and their ambient abiotic matrixes. Results showed that the levels of ∑18PBDEs and ∑13PAEs in abiotic matrixes followed the order of SPMs > surface sediments > seawater, and the cnidarian POP-uptake patterns (soft corals > hard corals) were as follows: coral mucus (138.49 ± 59.98 and 71.57 ± 47.39 ng g-1 dw) > zooxanthellae (82.05 ± 28.27 and 20.14 ± 12.65 ng g-1 dw) ≥ coral tissue (66.26 ± 21.42 and 34.97 ± 26.10 ng g-1 dw) > bleached corals (45.19 ± 8.73 and 13.83 ± 7.05 ng g-1 dw) > coral skeleton (35.66 ± 9.58 and 6.47 ± 6.47 ng g-1 dw, respectively). Overall, findings suggest that mucus checking is a key/facile diagnostic approach for fast detection of POP bioaccumulation (PB) in tropical corals. Although studied corals exhibited no consensus concerning hazardous levels of PB (log BSAF < 3.7), our bleaching evidence showed soft corals as the ultimate "summer winners" due to their flexibility/recovering ability.
