Cigarette butts are one of the most prevalent forms of litter worldwide and may leach toxic compounds when deposited in aquatic environments. Previous studies demonstrated that smoked cigarette leachate is toxic toward aquatic organisms. However, the specific bioavailable chemicals from the leachate and the potential for human and wildlife exposure through the food chain were unknown. Using a nontargeted analytical approach based on GC×GC/TOF-MS, 43 compounds were confirmed to leach from smoked cigarettes when exposed to a water source. Additionally, the bioaccumulation potential of organic contaminants in an edible fish, rainbow trout (Oncorhynchus mykiss), was assessed through direct exposure to the leachate of smoked cigarettes at 0.5 CB/L for 28 days. There was a significant reduction in fish mass among the exposed rainbow trout vs the control group (χ2 (1) = 5.3, p = 0.021). Both nontargeted and targeted chemical analysis of representative fish tissue identified four tobacco alkaloids, nicotine, nicotyrine, myosmine, and 2,2′-bipyridine. Their average tissue concentrations were 466, 55.4, 94.1, and 70.8 ng/g, respectively. This study identifies leached compounds from smoked cigarettes and demonstrates the uptake of specific chemicals in rainbow trout, thus suggesting a potential for accumulation in food webs, resulting in human and wildlife exposure.

“…There are industrial complexes located in the Imjin-Hantan River and Anseong Stream watershed areas, and the Han River mainstream watershed is one the most urbanized areas in South Korea. In other countries, studies measuring VOCs in aquatic environments have primarily investigated urban and industrial sources that exhibited relatively higher VOC concentrations than rural areas [19,22,23,50,51]. Therefore, the differences in the VOC concentrations among the sub-watershed areas are potentially related to the sources of the halocarbons.…”

Volatile organic compounds (VOCs) are ubiquitous pollutants in surface water, which is the main source of drinking water in South Korea. We investigated the behavior (concentration, distribution, and environmental risk) of eleven selected VOCs in the surface water of the Han River tributaries using purge-and-trap gas chromatography/mass spectrometry. The average concentration of VOCs was 0.29 ± 0.47 μg/L. Chloroform and trichloroethylene (TCE) were the major pollutants, accounting for approximately 64.2% and 25.6% of the total concentration, respectively, and showing that halocarbons accounted for 94%. Chloroform was positively correlated with TCE and xylenes, and TCE was positively correlated with tetrachloroethylene (PCE). No differences were observed in the temporal average concentrations of total VOCs, but the concentrations differed significantly among sub-watershed areas. The Imjin-Hantan River, Han River mainstream, and Anseong Stream watersheds had a high positive association with TCE, whereas the Bukhan and Namhan River watersheds had a strong positive link with chloroform. The contamination and detection frequency of VOCs were highest in industrial complexes, followed by urban and rural areas. Thus, point source pollution significantly contributed to VOC contamination of these tributaries. Risk quotients for most VOCs were <1, suggesting negligible risk. Considering the relatively high occurrence of VOCs and their potential ecological risks, continuous environmental monitoring and study of environmental impacts based on ecotoxicity studies of domestic aquatic species are warranted.

This study reports the occurrence and risk assessment of 2,4-Dinitrophenol (2,4-DNP), Phenol (PHE), and 2,4,4, in drinking water sources in three South western States in Nigeria (Osun, Oyo and Lagos). Groundwater (GW) and surface water (SW) were collected during dry and wet seasons of a year. The detection frequency of the phenolic compounds followed the trend: Phenol > 2,4-DNP > 2,4,6-TCP. The mean concentrations of 2,4-DNP, Phenol, and 2,4,6-TCP in GW/SW samples from Osun State were 639/553 µg L − 1 , 261/262 µg L − 1 , and 169/131 µg L − 1 respectively, during the rainy season and 154/7 µg L − 1 , 78/37 µg L − 1 , and 123/15 µg L − 1 during the dry season. In Oyo state, the mean concentration were 165/391 µgL − 1 for 2,4-DNP and 71/231 µgL − 1 for Phenol in GW/SW samples respectively, during rainy season. Generally, in the dry season, these values decreased. In any case, these concentrations are higher than those previously reported in water from other countries. The concentration of 2,4-DNP in water posed serious ecological risks to Daphnia on the acute scale while it was Algae on the chronic scale. Estimated daily intake and hazard quotient calculations suggests that 2,4-DNP in water pose serious toxicity concern to humans. Additionally, the concentration of 2,4,6-TCP in water from Osun State in both seasons pose signi cant carcinogenic risk to persons ingesting water from this State. Every exposure group were at risk from ingesting these phenolic compounds in water. However, this decreased with increasing age of the exposure group. Results from the Principal Component Analysis indicate that 2,4-DNP in water samples is from an anthropogenic source different from that for Phenol and 2,4,6-TCP. There is a need to treat these GW and SW before drinking while maintaining regular assessment of these water sources.drinking water (Sonawane and Korake, 2016). In Brazil, the Brazilian potability standard for drinking water set the maximum permissible level for 2,4,6-TCP at 200 ng L − 1 (Sartori et al., 2012). However, there is a dearth of data on the presence of these phenolic compounds in water bodies and drinking water sources in Africa, even though these compounds are vastly used in industries and particularly for agricultural purposes in the continent. Consequently, no limit has been determined for these priority pollutants in aquatic environments in West African countries.To make matters worse for millions of Africans, the major sources of drinking water are some of these aquatic environments, including streams, rivers, hand-dug wells and boreholes. In fact it is estimated that > 50% of Africans use groundwater as their primary source of drinking water (https://businessday.ng/opinion/article/world-water-day-2022-where-are-we/ ). Water from these sources is not pre-treated before use. The quality of these drinking water sources from Africa and especially Nigeria, with respect to phenolic compounds is relatively unknown.Based on the observed gaps, this study aims to provide baseline data on the occurrence of some p...
