Article Abstract
Social economy in Huaihe River Basin had undergone enormous changes during 1990-2010. The grain yield had increased by 58%, from 64.14 million tons to 101.21 million tons, and the urbanization rate had increased by 22%, from 13% to 35%. Assessing the negative impacts of these high intensive human activities caused by rapid social development on terrestrial ecosystem would serve as a scientific basis for quantitative management of regional ecology. This paper estimated the spatial and temporal distribution of net anthropogenic nitrogen input (NANI) in Huaihe River Basin during 1990-2010. The results showed that there was an increasing trend in NANI in the period of 1990-2001, and after that this trend was slower. The NANI increased from approximately 17232 kg N · km(-2) · a(-1) in 1990 to a peak of 28771 kg N · km(-2) · a(-1) in 2003, and then declined to 26415 kg N · km(-2) · a(-1) in 2010. Chemical fertilizer and atmospheric deposition were the largest two sources of NANI, followed by food & feed import and biological nitrogen. Contributions from both chemical fertilizer and atmospheric deposition had been increasing continuously, respectively from 64% and 16% in 1990 to 77% and 19%. Our findings implied that the shift from fertilizer-supported agriculture and fossil fuel-supported industry to sci-tech lead economic development is urgently needed.

The increasing presence of nanoplastics (NPs) and synthetic antioxidants like 3-tert -Butyl-4-hydroxyanisole (3-BHA) in the environment has attracted widespread attention about their combined toxicological effects on human health, particularly on renal function. This study explored to the combined impacts of NPs and 3-BHA at environmentally relevant concentrations on sub-chronic kidney injury in mice. Firstly, our results confirmed that the accumulation of 80 nm NPs in renal tissues, leading to structural abnormalities such as reduced mitochondrial cristae and increased empty bubbles in mice by transmission electron microscope (TEM) analysis.

Background: Bisphenol A (BPA), a widespread environmental pollutant, has been extensively studied for its effects on bacteria and plant, but its impact on rhizosphere bacterial communities and plant root traits is less understood. At the same time, the role of bacteria in helping plants resist adversity is widely recognized, but the relationship between BPA-induced with rhizosphere bacterial changes and root development is still unclear. Therefore, this study investigated the effects of varying BPA concentrations (1.

Nitrite (NO), a natural component of the nitrogen cycle, poses significant risks to both ecosystems and human health when present as a pollutant. Hence, it is essential to develop detection methods with high selectivity, sensitivity, and rapid response for measuring nitrite levels in water. This study introduces a novel colorimetric fluorescent probe PQ-N, which specifically recognizes NO in diverse environments including water, soil, and food.

Lesion mimic mutants (LMMs) are invaluable for uncovering the molecular mechanisms of programmed cell death (PCD) and plant immunity and identifying more LMMs expands our understanding of these complex processes. In this study, we characterized a novel rice LMM, , identified through heavy-ion beam irradiation. The mutant exhibits reddish-brown lesions from the tillering stage, reduced plant height, grain size, and fertility.
