• Tributyltin (TBT) is a toxic organotin compound that belongs to the group of Persistent Organic Pollutants (POPs) and it is documented to cause severe sexual disorders development in aquatic fauna. According to the present study, The TBT concentration in coastal water ranged from 303 ± 7.4 ngL−1 to 25 ± 4.2 ngL−1 wherein sediment was from 107 ± 4.1 ngKg−1 to 17 ± 1.4 ngKg−1. TBT in Perna viridis was found to range from 4 ± 1.2 ngKg−1 to 42 ± 2.2 ngKg−1 wet weight and in ascending order of the body weight. The highest TBT level in water and sediment was found in the Colombo port where the highest level of TBT in P. viridis (42 ± 2.2 ngKg−1) was recorded from the Dikkowita fishery harbor. A positive correlation between the number of male P. viridis and TBT level (p < 0.05) suggests possible reproductive impairment in aquatic animals exposed continuously to a high concentration of TBT. [Display omitted] •Solid Phase Micro Extraction is a sensitive, cost effective and novel precise method to identify and quantify TBT•The highest TBT concentration in water and sediment indicate that high amount of TBT inputs are occurring in Colombo port•Positive correlation between numbers of male P. viridis and TBT concentration suggest that possible reproductive impairment•Marinas in fishery and commercial harbors are likely sources of TBT contamination in Sri Lanka•Dietary consumption of contaminated seafood would be the main pathway of TBT exposure in the environmental biota
