Microplastic pollution, a major global environmental issue, is gaining heightened attention worldwide. Marginal seas are particularly susceptible to microplastic contamination, yet data on microplastics in marine sediments remain scarce, especially in the Beibu Gulf. This study presents a large-scale investigation of microplastics in the surface sediments of the Beibu Gulf to deciphering their distribution, sources and risk to marginal seas ecosystems.

Daunomycin is a chemotherapeutic agent widely used for the treatment of leukemia, but its toxicity toward healthy dividing cells limits its clinical use and its production by fermentation. Herein, we describe the development of a specialized cultivation medium for daunomycin production, including a shift to oil rather than sugar as the primary carbon source. This achieved an almost threefold increase in daunomycin yields, reaching 5.

Excessive concentrations of toxic metals are a global threat to aquatic systems. Taking a typical tributary (Zijiang River, ZR) of the midstream of the Yangtze River as the research area, the concentration distribution and chemical fractions occurrence characteristics of five toxic metals (Cd, Cr, Cu, Pb, and Zn) were analyzed, their potential sources were explored, and their contamination and ecological risk was assessed. In the surface waters and sediments, there were high concentrations of Zn, a low concentration of Cd, and small spatial differences in concentration among the upstream, midstream, and downstream.

Urban rivers are one of the main water sources for local residents. However, the rapid industrialization and urbanization caused serious heavy metals pollution in urban rivers, which posed harmful impact on human health and ecosystem. In this study, 134 sediment samples were collected from urban rivers in a typical Economic and Technological Development Zone (ETDZ) to evaluate the contamination status, ecological risk, biotoxicity, and potential source of 8 heavy metals including arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), plumbum (Pb), and zinc (Zn).

Electronic address:
The pervasive and escalating issue of toxic metal pollution has gathered global attention, necessitating the exploration of innovative ecological strategies like phytoremediation. This study explored the extent of potentially toxic metal contamination status and the effectiveness of three planted mangrove species (Avicennia marina, Bruguiera gymnorhiza,and Excoecaria agallocha) in phytoremediation efforts to reduce pollution level. The results indicated that the mean concentrations of elements in the sediment of the area followed a descending sequence: Fe (27,136.
