Occurrence and Distribution of 1,3-Diphenylguanidine, Benzotriazole, Benzothiazole, <i>N</i>-(1,3-Dimethylbutyl)-<i>N</i>′-phenyl-p-phenylenediamine, and Their Derivatives in Surface Water, Drinking Water, Stormwater Runoff, and Rainwater from New Yo

1,3-Diphenylguanidine (DPG), benzotriazole (BTR), benzothiazole (BTH), N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine (6PPD), and their derivatives are rubber additives (RAs) widely used in tires and various consumer products. Nevertheless, little is known about their occurrence in aquatic environments. We determined 17 RAs in 233 grab samples of water collected from New York State, USA, in 2024. The geometric mean concentration of ∑All (sum concentration of all 17 analytes) varied among different sample types in the following decreasing order: stormwater runoff (8330 ng/L) > river water (222 ng/L) > rainwater (183 ng/L) > tap water (157 ng/L) > lake water (80.3 ng/L) > swimming pool water (66.6 ng/L) > bottled water (5.95 ng/L). DPGs, BTRs, and BTHs were the dominant classes of chemicals found in stormwater runoff (accounting for 48% of ∑All), surface water and rainwater (55–89%), and tap water (97%), respectively. Water samples from the Mohawk River and Onondaga Lake contained elevated concentrations of DPGs, BTRs, and BTHs. The annual mass discharge of the 17 RAs from the Hudson River to the Atlantic Ocean was estimated to be as high as 10,200 kg. The calculated risk quotient of 6PPD-quinone was >0.1 in 38% of the river water samples, suggesting moderate to high ecological risks posed by these chemicals in the aquatic environment.
