“…TBA levels in water measured in this study are generally higher than what has been reported elsewhere, specifically, six to eight times higher than at the Great Barrier Reef, Australia, and up to two orders of magnitude higher than in Northern Europe and the Canadian Arctic (4,21,34,35). PCA has been reported in a wide range of concentrations in water, from <1 pg liter −1 to up to 290 ng liter −1 (36)(37)(38)(39)(40). Its concentration in this study was about one order of magnitude lower than the level reported in Lake Ontario but slightly higher than in seawater of the German Bight (North Sea) (39,40).…”

Halomethoxybenzenes are pervasive in the atmosphere at concentration levels that exceed, often by an order of magnitude, those of the persistent organic pollutants with which they share the attributes of persistence and potential for long-range transport, bioaccumulation, and toxic effects. Long ignored by environmental chemists because of their predominantly natural origin—namely, synthesis by terrestrial wood-rotting fungi, marine algae, and invertebrates—knowledge of their environmental pathways remains limited. Through measuring the spatial and seasonal variability of four halomethoxybenzenes in air and precipitation and performing complementary environmental fate simulations, we present evidence that these compounds undergo continental-scale transport in the atmosphere, which they enter largely by evaporation from water. This also applies to halomethoxybenzenes originating in terrestrial environments, such as drosophilin A methyl ether, which reach aquatic environments with runoff, possibly in the form of their phenolic precursors. Our findings contribute substantially to the comprehension of sources and fate of halomethoxybenzenes, illuminating their widespread atmospheric dispersal.
