Effects of D-Tetramethrin on Zebrafish Development and Immune System

D-tetramethrin is a common insecticide that is important for the control of mosquito-transmitted diseases such as malaria and dengue and, due to its widespread use, it is frequently detected in environmental systems. However, there is currently very little information on the influence of D-tetramethrin on non-target organisms. In this study, zebrafish embryos were exposed to various concentrations of D-tetramethrin (0, 3, 6, and 9 mg/L) from 6 to 72 h past fertilization (hpf) to ascertain the influence of D-tetramethrin on the zebrafish immune system and development. We found that D-tetramethrin exposure led to a significant decrease in heart rate, an increase in the yolk area and tail flick frequency, and a shortening of body length in zebrafish larvae, compared with the control group. The number of macrophages and neutrophils in the experimental group of zebrafish larvae decreased significantly and the oxidative stress levels increased compared with the control group. The malondialdehyde (MDA) content and reactive oxygen species (ROS) content increased significantly, while catalase (CAT) activity increased and superoxide dismutase (SOD) activity decreased in the experimental group. At the same time, apoptosis increased in the zebrafish embryo cells, and the expression of apoptosis-related genes such as p53, Bax, and Bcl-2 was abnormal. Moreover, the pro-inflammatory genes IL-8, IFN-γ, IL-6, and TNF-α were up-regulated, while the anti-inflammatory gene, IL-10, was down-regulated. Therefore, D-tetramethrin significantly affects the immune system and oxidative stress levels in zebrafish, inducing cell apoptosis and negatively affecting embryo development. These results provide novel data for the toxicity of D-tetramethrin and the potential adverse effects of environment residues. © 2025 Wiley Periodicals LLC.

With rapid global industrialization, environmental pollution has become one of the major problems of human society. Photocatalysis can be applied to solve environmental problem by using inexhaustible solar energy. As a novel two-dimensional material, graphite carbon nitride (g-C3N4) has been widely applied in many photocatalytic reactions. However, in terms of its practical applications, g-C3N4 still has limitations, including poor photoexcited charge separation, limited range of visible light absorption, and low surface areas. Hence, current research on g-C3N4 mainly focuses on improving its photocatalytic performance. In this review, we summarize various methods to improve g-C3N4’s light absorption and photo-induced charge transfer, including vacancy engineering, morphology control, heteroatom doping, and forming heterostructure. The applications of g-C3N4 and its derivatives in photodegradation of organic pollutants are also discussed in detail. Finally, the challenges and future research directions of g-C3N4 photocatalysts are summarized to promote their environmental applications.

The terrestrial ecosystem plays an important role in regulating the regional carbon balance, in particular for China, where ecological projects during past decades [1,2] have led to large increases in China's land carbon sinks, partially offsetting fossil fuel emissions. Therefore, accurate evaluation of land carbon fluxes in China is critical for improving our understanding of the magnitude of China's carbon budget, and projecting its future changes.

Biochar, a soil conditioner containing significant amounts of polycyclic aromatic hydrocarbons (PAHs), has gained widespread popularity in agricultural practices due to its advantages in improving soil fertility and carbon sequestration. While biochar may increase soil black carbon (BC) and PAH contents, the quantitative accumulation of BC and PAHs in different soil environments under varying biochar addition dosages remains poorly understood. Here, we investigated the content and composition of black carbon (evaluated using benzene polycarboxylic acids, BPCAs) and PAHs in soils treated with different biochar addition dosages from two long-term experimental farmlands in Ningxia (5-year) and Shandong (7- and 11-year), China. Results showed that increasing cumulative biochar dosage caused elevated contents of black carbon and PAHs, accompanied by decreases in their retention efficiencies. Contrasting retention was observed between sites, with the Shandong site characterized by higher retention efficiencies of BPCAs and lower retention efficiencies of PAHs, possibly owing to its higher temperature, more sandy soil texture, less irrigation, and lower sunlight intensity. Despite both black carbon and PAHs originating from biochar and sharing similar condensed aromatic structures, there was no significant correlation between the contents of black carbon and PAHs, indicating distinct behaviors and fates of these compounds. These findings emphasize the importance of optimizing biochar addition dosages and considering site-specific environmental factors for effective soil black carbon sequestration through biochar application.
