Case Study

Toxicity Evaluation of Naphthalene Sulfonic Acid Congeners Such as Calcium Dinonylnaphthalene Sulfonate

Matten, K. J., et al. Environmental Pollution, 2020, 267, 115604.

Naphthalene sulfonic acids (NSAs), widely employed as dispersants in dyes, rubbers, and pesticides, and as anti-corrosive agents in coatings and sealants, were assessed for their toxicity to benthic organisms Tubifex tubifex and Hyalella azteca. The study focused on three NSA variants-barium dinonylnaphthalene sulfonate (BaDNS), calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS)-using substrates with contrasting organic carbon content: sand (0%) and sediment (2%).
Key Findings
For T. tubifex, juvenile production emerged as the most sensitive endpoint. In sand, 28-day EC50 values were <18.2, 22.2, and 64.0 μg/g dry weight (dw) for BaDNS, CaDNS, and DNDS, respectively, while sediment EC50s were markedly higher (281.3, 361.6, and 218.9 μg/g dw). H. azteca 28-day LC50s in sand ranged from 49.0 (DNDS) to 115.3 μg/g dw (BaDNS), with sediment LC50s exceeding 627.3 μg/g dw for BaDNS and CaDNS. Notably, when toxicity was evaluated based on NSA concentrations in overlying water (a key exposure route for H. azteca), BaDNS and CaDNS exhibited 3-4 orders of magnitude greater toxicity than DNDS.
Toxicity was consistently amplified in low-organic carbon substrates: NSA effects were >3-fold stronger in sand for all H. azteca endpoints and for T. tubifex sublethal responses. Sediment organic carbon reduced bioavailability, likely sequestering NSAs and mitigating their toxicity.
