Their presence in the environment is largely due to in situ generation from physical and chemical weathering of larger plastics, and thus has left environmental community concerned in the post-banned era of microbead use in personal care products through the passage of Microbead-Free Waters Act in the United States. To improve understanding of secondary microplastic formation, accelerated weathering has been conducted on four materials (high-density polyethylene, high impact polystyrene, nylon 6, and polypropylene) under ultraviolet radiation (equivalent to 44 days in full sun) in simulated seawater. Physical and chemical characterization of the plastics were completed following ultraviolet exposure. This simulated weathering generated microfibers from high-density polyethylene and nylon 6, while high impact polystyrene and polypropylene did not physically degrade. The techniques used were applied to sediment samples containing plastic pellets collected from Cox Creek in Port Comfort, TX (near a large plastics manufacturer), which were purified for analysis and were found to contain microplastics composed of polypropylene and polyethylene. These findings can be used to determine degradation pathways and plastic source tracking, which can facilitate risk assessment and environmental management.Seafood is one of the leading imported products implicated in foodborne outbreaks worldwide. Coastal marine environments are being increasingly subjected to reduced water quality from urbanization and leading to contamination of important fishery species. Given the importance of seafood exchanged as a global protein source, it is imperative to maintain seafood safety worldwide. To illustrate the potential health risks associated with urbanization in a coastal environment, we use next-generation high-throughput amplicon sequencing of the 16S ribosomal RNA gene combined with infrared spectroscopy to characterize and quantify a vast range of potential human bacterial pathogens and microdebris contaminants in seawater, sediment and an important oyster fishery along the Mergui Archipelago in Myanmar. Through the quantification of >1.25 million high-quality bacterial operational taxonomic unit (OTU) reads, we detected 5459 potential human bacterial pathogens belonging to 87 species that are commonly associated with gut microbiota and an indication of terrestrial runoff of human and agricultural waste. INCB084550 Oyster tissues contained 51% of all sequenced bacterial pathogens that are considered to be both detrimental and of emerging concern to human health. Using infrared spectroscopy, we examined a total of 1225 individual microdebris particles, from which we detected 78 different types of contaminant materials. The predominant microdebris contaminants recovered from oyster tissues included polymers (48%), followed by non-native minerals (20%), oils (14%) and milk supplement powders (14%). Emerging technologies provide novel insights into the impacts of coastal development on food security and risks to human and environmental health.To reduce health inequalities requires interventions that address the social determinants of health. The responsibilities, at the ministerial level, for these determinants are mainly situated outside the ministry of health. Accordingly, interventions to reduce health inequalities require coordination between the ministry of health and other ministries. Yet, a large literature in public administration has demonstrated that cross-sectoral cooperation is hard to achieve. The goal of this paper was to examine whether inter-ministerial cooperation relating to the reduction of health inequalities is occurring in practice. Semi-structured interviews were performed with senior officials at 26 ministries in Finland, Norway, and Sweden. The interviews were analyzed both qualitatively and quantitatively. The point of departure was a question if the ministries had initiated substantial measures, such as reforms, regulations, funding, or fiscal strategies, aiming to promote health equity in the population and, if so, if this was done in cooperation with other ministries. The informants reported 80 measures intended to promote health equity and stated inter-ministerial cooperation for 65 of these measures. Many informants described that cooperation between the ministries was routine and well-functioning. Thus, there was no recorded lack of inter-ministerial cooperation. However, the measures that were reported, seemed to be insufficient to reduce health inequalities, both due to lack of extent and lack of effectiveness. This might be due to insufficient political commitment to tackle health inequalities. If so, the WHO Health in All Policies approach might not be effective.Soil treatment units (STUs) receiving effluent from on-site wastewater treatment systems (OWTSs) rely on the gradual development of a microbial biomat/biozone at the infiltrative surface for optimal effluent distribution and pollutant attenuation. Here, we present the first direct measurement of gradual biomat development in the field in STU trenches receiving either primary (PE) or secondary treated effluent (SE) under identical environmental, hydrological and subsoil conditions. Two domestic OWTSs were constructed in Ireland and monitored over a period of >2 years using an automated, three-dimensional network of buried soil water content sensors tracking water flow and retention within the soil underneath the infiltrative surface. While trenches receiving PE expressed signs of biomat formation along the entire length of STU trenches, biomats in trenches receiving SE were significantly muted and did not extend further than 10 m from the inlet at the end of the study. The presence of a mature biomat helped to retain soil moisture above background levels and made the system more resilient towards drought events and desiccation stress but led, in one case, to effluent ponding within the trenches. A growth-limited non-linear model fit revealed that biomats in SE trenches are expected to remain considerably shorter and will not spread along the entire trench design length, even after 10 years of operation, which is contrary to prevalent design assumptions. Muted biomat growth, on the contrary, might lead to localized hydraulic and pollutant overloading and has been shown previously to negatively affect the ability to attenuate pollutants effectively within the soil profile before the effluent reaches the groundwater.
