Summary: Lichens are symbiotic associations consisting of a photobiont and a mycobiont, and their biosynthetic gene clusters play a crucial role in biotechnological applications. In this study, we compared the biosynthetic gene clusters of three lichen mycobionts and extracted a mycobiont bin containing 214 gene clusters from a high-quality metagenome. Most of these gene clusters were associated with T1PKSs, NRPSs, and terpenes. Our findings contribute to the understanding of PKS diversity in lichenized fungi and provide a foundation for further exploration in biotechnology and molecular evolution.

Summary: This article presents the current knowledge on Canadian PAC emission sources, with forest fires dominating the emissions nationally. Non-industrial sources are estimated to be the second largest contributor, showing moderate decreases in recent decades. Industrial point sources have seen considerable reductions, while fugitive emissions from other industrial sources remain a gap in our understanding. Overall, there is uncertainty in emissions data and regional/local scale examination is needed to determine the sources contributing most to human and ecosystem exposure.

Summary: An improved understanding of the historical variation in the emissions and sources of black carbon and polycyclic aromatic compounds may help assess the environmental effects of the Atmospheric Brown Cloud in SE Asia. The study found that soot fluxes have been increasing in recent times, but at a lower rate than previously estimated, possibly due to a decreasing biomass burning contribution. High- and low-molecular-weight PAHs, OPAHs, and azaarenes all sharply increased after 1980, indicating a shift from biomass burning to fossil fuel combustion emissions.

Summary: Extensive research conducted over 30 years examines the leachability and runoff of asphalt in global settings. The widespread usage of asphalt in construction materials highlights the need to understand its environmental impact. This study investigates the influence of sunlight exposure on water quality, particularly the release of hazardous organic compounds. Results show that exposing thin films of asphalt binder underwater to solar simulation leads to significant water-soluble species. However, simulating real-world conditions by exposing the binder to sunlight before water immersion reduces compound formation.

Summary: Wildland fire activity and particulate matter emissions have been increasing in the United States over the past two decades due to factors like increased temperature, drought, and high forest fuel loading. Monitoring networks are mainly concentrated in populous areas, leading to a lack of data in smaller towns affected by wildland fire smoke. Evaluation of small form factor PM2.5 samplers showed that only the ARA Instruments N-FRM Sampler met federal reference method guidelines for accuracy in both ambient and simulated wildland fire conditions.

Summary: Particulate matter (PM) from wildland fires poses health risks to individuals living in affected areas, and limiting exposure is crucial for protecting public health. However, monitoring PM concentrations in smoke impacted environments is challenging due to measurement interferences and sampling conditions. This study evaluates the accuracy of the Teledyne-API Model T640 PM Mass monitor compared to the filter-based federal reference method (FRM) for measuring PM2.5 in laboratory-based studies. The T640 has gained popularity for monitoring PM2.5 in the US, but the study finds both positive and negative measurement artifacts associated with PM concentration and smoke aerosol properties. Overall, this study highlights the importance of accurate PM monitoring during wildland fire events.
