The unparalleled use of neonicotinoids in various sectors including agriculture has currently reintroduced them as emerging pollutants/hazards due to their endocrine-disrupting nature. High water solubility, low volatility, and persistent nature have resulted in their accumulation in the environment. Thus, investigating efficient and sustainable methods for the remediation of contaminated environments due to this pollutant is imperative.</p><h3>Recent Findings.</h3><p>Bioremediation provides a cost-effective and environment-friendly option over conventional physicochemical techniques that produce toxic byproducts. The microbial route for degradation has the potential to completely mineralize neonicotinoids by virtue of their adaptive and diverse metabolic machinery. Potent microbes such as <i>Ensifer</i>, <i>Phanerochaete</i>, <i>Bacillus</i>, <i>Ochrobactrum</i>, <i>Trametes</i>, <i>Rhodococcus</i>, <i>Sphingobacterium</i>, and <i>Pseudomonas</i> have been isolated and screened for their immense degradation potential, and the metabolites, degradative enzymes, and transformation pathways have been elucidated.

The gills had higher levels of most MEs than the liver and muscle. Only a few MEs in the tissues of both fish species demonstrated significant associations with fish length or weight. There were no significant differences between male and female fish in terms of the levels of most metals in tissues. The estimated daily intake (EDI) values of metals were below the reference doses.

Because the gills and liver are metabolically active organs, they had higher levels of MEs than the muscle. The relationships between the levels of MEs in the tissues and fish size were both unclear and inconsistent. The results indicated that ME accumulation in tissues of individuals within the same species was not significantly influenced by gender. The THQ, HI, CR, and EDI values indicated that no adverse health consequences are expected for consumers. It was established that daily consumption of less than 50 g of <i>C. tinca</i> or 80 g of <i>S. pursakensis</i> would not be harmful to consumers’ health. Nutritional evaluation results indicated that both fish species are good sources of essential MEs.

Some significant accumulation of microplastics occurred in local reaches of rivers, lakes, and reservoirs, which was influenced by different environment factors. Though petroleum-based plastics were defined as non-degradable plastics, physical, chemical, and biological degradation pathways of microplastics were constantly verified to occur widely in surface waters. More and more microplastics-degrading microbes, including bacteria, fungi, and even virus, were identified or speculated to directly or indirectly take part in the biodegradation of microplastics. Synergistic degradation processes of microplastics were continuously found in some natural waters, and the mechanisms were explored.</p><h3>Summary</h3><p>Multiple sinks of microplastics occurred in the sediments of surface water, such as urban rivers, the mouth of the lake, and reservoirs. The diversity of microplastics-degrading microbes may be much more than what we know previously. This review highlights that there are two scales of synergistic degradation of microplastics, which couple different microbes in the plastispheres and couple biophysical chemical actions in surface water separately.

Since the structural characteristics of biochar have a great impact on Fe⁰ loading, a comprehensive review of the structural characteristics of biochar is needed to explain its influence on ZVI formation during preparation.
