Summary: The study investigated round goby growth in Lake Michigan and Lake Huron using a multi-model approach, finding that round gobies in Lake Michigan generally achieve larger sizes at the same age and grow faster than those in Lake Huron. The results suggest a substantial degree of uncertainty in model selection.

Summary: This study investigates the population trends of invasive dreissenid mussels in the upper Great Lakes. It shows that these mussels are expanding into deeper waters and have high biomass in Lake Michigan. The size-frequency distribution data indicates that they are reproducing in deep water areas, suggesting that their expansion is likely to continue.

Summary: Sucker species are common benthic invertebrates in North American waterbodies, but their diets in the Great Lakes are poorly understood. This study focused on the gut contents of white suckers and longnose suckers in Lake Michigan and Saginaw Bay, Lake Huron. Chironomidae and Amphipoda were major prey for white suckers, while Amphipoda and Isopoda dominated the gut contents of longnose suckers, indicating a preference for certain prey types.

Summary: This study reports the levels and distribution of polychlorinated biphenyls (PCBs) in residential soils in East Chicago, Indiana. The PCB concentrations were found to be relatively high and influenced by nearby contamination sites. The concentrations increased with the total organic carbon content and proximity to the contaminated area. Despite the higher concentrations compared to other locations, the samples were still below the current soil remediation goal.

Summary: Understanding water level fluctuation patterns in the Great Lakes is crucial for adaptive management practices. This study utilized continuous wavelet transformation to analyze monthly water levels in Lake Huron-Michigan, revealing various long-term periodicities. The analysis highlighted the role of runoff and evaporation in driving water level fluctuations.

Summary: This study reports the reductive dehalogenation of penta-BDEs and PCBs by Dehalococcoides mccartyi strain MB. The strain was able to efficiently debrominate penta-BDEs and dechlorinate PCBs through reductive dehalogenation. The research also revealed the involvement of MbrA in the dehalogenation process and explored the mechanism through proteomic profiling and transcriptional analysis.

Summary: This paper provides environmental information on the recovery of waste plastic in a certified factory in an industrial park in Eastern China. The study analyzes the emissions of particulate matters, heavy metals, PAHs, PCBs, and PBDEs during the production process. The results show that washing and crushing processes are the main sources of pollution, and management strategies are proposed to mitigate the environmental hazards caused by waste plastic recovery.

Summary: This study investigates the occurrence and spatial pattern of persistent organic pollutants (POPs) in soils from the Larsemann Hills, East Antarctica. The main contaminants identified were organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). The results indicate that OCPs in soils are primarily caused by long-distance atmospheric transport, while local sources can also contribute in areas heavily impacted by human activities. Different distribution patterns were observed for PCBs and PBDEs, indicating the possibility of multiple pollution sources.

Summary: Mercury-contaminated fish in the Great Lakes basin pose a serious threat to humans and wildlife. Measurements of total gaseous mercury (TGM) over Lake Superior and Lake Michigan show relatively low concentrations compared to other monitoring stations in Canada and the United States. The study also found significant correlations between TGM and other pollutants such as organic carbon, sulfate, nitrate, and ammonium over Lake Michigan.

Summary: The study investigated the associations between flame retardants (FRs) concentrations and changes in the hypothalamic-pituitary-thyroid (HPT) axis in northern fulmars, finding that PBDEs and other FRs were linked to alterations in thyroid status, affecting thyroid hormone levels and gene expression. The results suggested that exposure to moderate levels of FRs could lead to thyroid axis perturbation at the molecular/biochemical levels in seabird species in the North Atlantic.

Summary: A program aiming to reintroduce the Northern Aplomado falcon in south Texas and southwestern United States started in the late 1970s and has shown success with breeding pairs steadily increasing. Research has shown low levels of environmental contaminants in Aplomado falcon eggs, indicating positive progress in reducing pollution impact on the species.

Summary: The study reveals a hydraulic connection between a deflated parabolic dune east of Lake Michigan and Lake Michigan-Huron, influencing water levels in the wetlands/slack lying within the dune. Rising lake levels lead to higher water levels in the wetlands/slack and a transition in vegetation types.

Summary: This study investigated the potential health effects of organohalogen compounds (OHCs) on pet cats. The results showed that exposure to harmful substances leads to a decrease in serum thyroid hormone levels and chronic oxidative stress in pet cats. Parent compounds and phenolic compounds exhibit different mechanisms of action and biological effects.
