Plastic waste is a ubiquitous form of marine pollution and recent studies have identified threats of plastic debris and the associated chemical compounds to wildlife. Sponges pump substantial quantities of water and are important in benthic-pelagic coupling, making them susceptible to interacting with such pollutants in the water column. Here, a method to detect common plastic-associated compounds including phthalates, a phthalate metabolite, bisphenol-A, and a brominated flame retardant in sponge tissue was developed. The method was applied to samples of Xestospongia muta and Niphates digitalis from a reef in the Florida Keys. All sponge samples had quantifiable levels of di(2-ethylhexyl) phthalate, with trace levels of the associated metabolite detected in some N. digitalis samples. There was no quantifiable detection of bisphenol-A, or the brominated flame retardant. This work is a preliminary assessment of the relationship between plastic marine debris and marine sponges.

More than 16,000 chemicals are incorporated into plastics to impart properties such as color, flexibility, and durability. These chemicals may leach from plastics, resulting in widespread human exposure during everyday use. Two plastic-associated chemicals-bisphenol A (BPA) and di(2-ethylhexyl) phthalate (DEHP)-and a class of chemicals-brominated flame retardants [polybrominated diphenyl ethers (PBDEs)]-are credibly linked to adverse health and cognitive impacts.

Benzotriazoles (BZTs) and benzothiazoles (BTs) are high-production-volume chemicals utilized in many different commercial products and industrial processes, such as metal corrosion inhibitors, vulcanization accelerators, plastic-associated UV stabilizers, and pharmaceutical precursors. This study assessed age, gender, and temporal trends of BZTs and BTs in deidentified surplus pathology urine samples, pooled and stratified by age, gender, and sample collection year from a general Australian population (168 pools representing 16,800 individuals). Tolyltriazole (TTri), 5,6-dimethyl-1H-benzotriazole (DMBZT), 1,3-benzothiazole (BTH), 2-hydroxybenzothiazole (2-OH-BTH), and 2-aminobenzothiazole (2-amino-BTH) were detected in >50% of the pools.

Epidemiological research investigating the impact of exposure to plastics, and plastic-associated chemicals, on human health is critical, especially given exponentially increasing plastic production. In parallel with increasing production, academic research has also increased exponentially both in terms of the primary literature and ensuing systematic reviews with meta-analysis. However, there are few overviews that capture a broad range of chemical classes to present a state of play regarding impacts on human health.

Understanding the impact of plastic and its additives on wild species is crucial as their presence in the environment increases. Polybrominated diphenyl ethers (PBDEs), once used as flame retardants, were restricted due to known toxic effects, but are still detected in the environment. Naturally occurring methoxylated PBDEs (MeO-BDEs) can result from PBDE transformation and may cause similar hazardous effects.

Purpose Of Review: To present recent evidence that strengthens the concept that exogenous pollutants contribute to adipose dysfunction and increased rates of disease and to highlight the ineffective regulation of this risk as industry switches to related but similarly toxic variants.
Recent Findings: Substitutes for common phthalates and the highly regulated bisphenol A (BPA) show similar deleterious effects on adipocytes. The well tolerated limit for BPA exposure has been reduced in Europe to below the level detected in recent population studies.
