Microplastics are ubiquitous and persistent contaminants in the ocean a pervasive preventable threat to health of marine ecosystems. come wide variety shapes, sizes, plastic types, each with unique physical chemical properties toxicological impacts. Understanding magnitude microplastic problem determining highest priorities for mitigation require accurate measures occurrence environment identification likely sources. The field pollution is its infancy, there not yet widely accepted standards...
Abstract Microplastic particles (MPs) are ubiquitous across a wide range of aquatic habitats but determining an appropriate level risk management is hindered by poor understanding environmental risk. Here, we introduce framework for ecosystems that identifies four critical thresholds, ranging from low regulatory concern to the highest where pollution control measures could be introduced mitigate emissions. The thresholds were derived using species sensitivity distribution (SSD) approach and...
Abstract To assess the potential risk of microplastic exposure to humans and aquatic ecosystems, reliable toxicity data is needed. This includes a more complete foundational understanding better characterization hazards they may present. expand this understanding, an international group experts was convened in 2020–2021 identify critical thresholds at which microplastics found drinking ambient waters present health organisms. However, their findings were limited by notable gaps literature....
About 3 billion new tires are produced each year and about 800 million become waste annually. Global dependence upon from natural rubber petroleum-based compounds represents a persistent complex environmental problem with only partial often-times, ineffective solutions. Tire emissions may be in the form of whole tires, tire particles, chemical compounds, which is transported through various atmospheric, terrestrial, aquatic routes built environments. Production use generates multiple heavy...
Abstract Throughout the past decade, many studies have reported adverse effects in biota following microplastic exposure. Yet, field is still emerging as current understanding of toxicity limited. At same time, recent legislative mandates required environmental regulators to devise strategies mitigate pollution and develop health-based thresholds for protection human ecosystem health. The publication rate also presents a unique challenge scientists, managers, other communities may find it...
Wildfires can be extremely destructive to communities and ecosystems. However, the full scope of ecological damage is often hard assess, in part due limited information on types chemicals introduced affected landscapes waterways. The objective this study was establish a sampling, analytical, interpretive framework effectively identify monitor contaminants emerging concern environmental water samples impacted by wildfire runoff. A nontargeted analysis consisting comprehensive two-dimensional...
We evaluated the occurrence of 154 organic contaminants from multiple chemical/use classes in San Francisco Bay watersheds during storm events, revealing complex mixtures and high concentrations transported to receiving waters.
While the antimicrobial ingredient triclosan has been widely monitored in environment, much less is known about occurrence and toxicity of its major transformation product, methyl triclosan. An improved method was developed validated to effectively extract quantify both contaminants fish tissue used characterize concentrations small prey areas San Francisco Bay where exposure via municipal wastewater discharges expected be highest. Concentrations (0.44-57 ng/g wet wt, median 1.9 wt) (1.1-200...
