Environmental distribution and ecotoxicological concerns of phthalic acid esters in creek ecosystem
The long-term ecological risk of synthetic organic contaminants, exclusively endocrine disrupting chemicals (EDCs) such as phthalates has threatened reclaimed seawater quality in marine environment. In this study, environmental distributions of 14 phthalic acid esters (PAEs) in seawater, and biota (fish and crab) across Thane Creek, Mumbai India is reported. Identification and quantifications of phthalates in environmental matrices was carried out using GC-MS technique. Abundance of phthalates in each matrix was discussed and compared with literature value. Total phthalate esters concentrations in seawaters, fish and crab samples were found to be 104.8 ± 37.8 μg L−1, 113 ± 36.4 μg g−1 and 155 ± 38 μg g−1 (dry weight) respectively. Di-n-butylphthalate (DBP) was most abundant compound among analyzed PAEs in all tested aquatic media. In situ bio-concentration factors (BCFs) were calculated for all monitored phthalates in fish and crabs and compared with log Kow values. Risk quotient and estradiol equivalent concentration were also calculated to evaluate ecological risk and estrogenic potential of seawater in terms of DBP and di (2-ethylhexyl) phthalate. The average values of total PAEs daily intake were calculated as 58.1 ± 13.6 and 79.6 ± 19.6 (µg kg–1-bw/day) for fish and crab respectively in an adult population.
