To accurately assess the environmental risks, it is essential to separately investigate intracellular and extracellular ARGs (iARGs and eARGs) due to their distinct roles in resistance persistence and horizontal gene transfer. However, the impact of sulfadiazine (SDZ) on iARGs and eARGs, and the mechanisms involved in the composting process remain under further investigation. In this study, composts with SDZ concentrations of 5 and 50 mg/kg were constructed, and ARGs, microbial community composition and functional pathways were analyzed. The results showed that the abundance of iARGs varied significantly under SDZ selective pressure, while eARGs showed no significant differences. Specifically, i-<i>erm</i> decreased in the 50SDZ group, likely due to competition for ecological niches. The abundance of <i>erm</i>A, <i>erm</i>B and <i>erm</i>F decreased by approximately 97%, 85%, and 84%, respectively. i-<i>sul</i> increased by 127% to 156% in SDZ-added groups but not dose-dependently. <i>Bacillus</i>, <i>Paracoccus</i>, <i>Pseudomonas</i>, and <i>Caproiciproducens</i> were predominant in the SDZ-added groups.

Organismal behavioural biomonitoring enables facile broad-spectrum toxicity detection, with distinct strengths over traditional water-quality sensing. Bivalve molluscs make ideal biomonitors, using alterations within two behaviours, valve movements and cardiac activity. Commercial systems monitoring these are costly, and often inflexible, whilst published methods typically lack broad suitability or requisite detail, or necessitate expertise; widespread application can be hindered, especially in the Global South and remote locations, despite the benefits for water monitoring. Furthermore, integration of both behaviours in systems is uncommon, despite probable gains in informativeness and sensitivity. Therefore, in the current work, a novel prototype set-up to simultaneously monitor valve movements and cardiac activity in multiple specimens was designed, constructed, and demonstrated. Employing popular, sophisticated, and robust technological approaches, the system caters for many bivalves (sessile/mobile, freshwater/marine). Reproducible, inexpensive, and uncomplicated, the low-power system centres around a Raspberry Pi (3B+) microcontroller, compatible with manifold open-source software. Monitoring eight unfixed animals for approximately £200 (during 2020), the system is adaptable for specimen numbers, type/rate of data capture, and operational conditions/environment. It is also scalable; miniaturisation and economies of scale should reduce the size and cost of a single set-up, making wider deployment of multiple systems, and larger cohorts, increasingly feasible. In providing extensive detail, the current work encourages further application of such monitoring capability. Widespread deployment or biomonitoring networks could revolutionise water management, improving protection of aquatic ecosystems and human health.

Results showed that sediments effectively mitigated water quality deterioration when acting as a 'sink' for pollutants. After four and a half hours, the pollutant concentration at the outlet was reduced to 0.56 mg/L due to sediment adsorption, compared to 23.573 mg/L without sediment. When acting as a 'source,' sediments released pollutants into the water, resulting in elevated concentrations in shallower river sections that subsequently migrate downstream, leading to pollution levels exceeding Class IV water standards. During combined sewer overflow incidents, sediments shortened retention times of elevated pollutant concentrations and reduced overall levels. At selected cross-sections, the durations during which water quality exceeded standards were reduced by 5.0%, 23.4%, and 27.5%, respectively.
