Quick Approaches for Assessing Ocular Toxicity with Zebrafish
The presence of contaminants in the environment has increased, and studies have demonstrated that these contaminants have the ability to penetrate the blood–retinal barrier and directly affect the visual systems of organisms. Zebrafish are recognized as an ideal model for human eye diseases due to their anatomical and functional similarities to the human eye, making them an efficient and versatile organism for studying ocular toxicity caused by environmental contaminants in the field of environmental toxicology. Meanwhile, zebrafish exhibit a diverse repertoire of visually mediated behaviors, and their visual system undergoes complex changes in behavioral responses when exposed to environmental contaminants, enabling rapid assessment of the ocular toxicity induced by such pollutants.

ROS and Antioxidants in Halophytes
Reactive oxygen species (ROS) are excited or partially reduced forms of atmospheric oxygen, which are continuously produced during aerobic metabolism like many physiochemical processes operating throughout seed life. Previously, it was believed that ROS are merely cytotoxic molecules, however, now it has been established that they perform numerous beneficial functions in plants including many critical roles in seed physiology. ROS facilitate seed germination via cell wall loosening, endosperm weakening, signaling, and decreasing abscisic acid (ABA) levels. Most of the existing knowledge about ROS homeostasis and functions is based on the seeds of common plants or model ones.

Applied Soil Remediation Strategies in Coal Mining Areas
Coal remains a very important source of energy for the global economy. Surface and underground coal mining are the two major methods of coal extraction, and both have benefits and drawbacks. Surface coal mining can have a variety of environmental impacts including ecosystem losses, landscape alteration, soil destruction, and changes to surface and groundwater quality and quantity. In addition, toxic compounds such as heavy metals, radioactive elements, polycyclic aromatic hydrocarbons (PAHs), and other organic contaminants are released in the environment, ultimately affecting the health of ecosystems and the general population. Underground mining has large impacts on underground water supplies and water quality, but generally has less visual surface impacts such as leaving waste and tailings on the surface and subsidence problems. In response to the concern about these environmental issues, many strategies have been developed by scientists and practitioners to minimize land degradation and soil pollution due to mining.

Nanoparticles and Their Role in Heavy Metal Bioremediation
Physical and chemical techniques are used to remove heavy metals (HMs) from contaminated soil. Microbial-metal interaction, a novel but underutilized strategy, might be used to lessen the stress caused by metals on plants. For reclaiming areas with high levels of heavy metal contamination, bioremediation is effective and environmentally friendly. Nanotechnology greatly improves the process of bioremediation, and its application in heavy metal bioremediation.

Freshwater Invertebrates in Biomonitoring
Invertebrates are excluded from ethical consideration in the procedures of environmental protection, which results in the killing of many more individuals during sampling than necessary. Biomonitoring is used as a routine method for environmental protection that results in the cruel death of even millions of aquatic animals annually.

The Impact of Bitcoin on the Environment
While blockchain and distributed ledger technology offer immense potential for applications in transparency, security, efficiency, censorship resistance, and more, they have been criticized due to the energy-intensive nature of the proof of work consensus algorithm, particularly in the context of Bitcoin mining. Bitcoin’s environmental impact has been portrayed in comparison to countries (Netherlands, Ireland, Argentina) and to industries (steel, aluminum, gold, banking, Christmas lights, aviation, tumble dryers, and even the global monetary system). The former is usually preferred by critics, as it gives a sense of the scale of Bitcoin energy consumption. In contrast, the latter is usually preferred by advocates, who highlight that many industries surpass individual countries in energy consumption and this is not usually seen as a problem. Bitcoin’s environmental impact are not confined to GHG emissions but also encompass issues such as e-waste and noise pollution.

Mercury Interactions with Natural Phytoplankton
The biogeochemical cycling of mercury in aquatic environments is a complex process driven by various factors, such as ambient temperature, seasonal variations, methylating bacteria activity, dissolved oxygen levels, and Hg interaction with dissolved organic matter (DOM). As a consequence, part of the Hg contamination from anthropogenic activity that was buried in sediments is reinserted into water columns mainly in highly toxic organic Hg forms (methylmercury, dimethylmercury, etc.). This is especially prominent in the coastal shallow waters of industrial regions worldwide.

Low-Carbon Logistics Capability
It is crucial to figure out how to achieve sustainable economic growth while fostering the growth of the logistics sector and the economy by expanding low-carbon logistics capability. The term "low-carbon logistics capacity" refers to a logistics operation's capacity to achieve sustainable development in the context of the needs of the low-carbon economy. Research and development capacity, economic development, energy consumption, and other considerations, have an impact on low-carbon logistics capability. Enhancing low-carbon logistics capability does not imply that the logistics sector should cut energy use and pursue a zealous reduction in carbon emissions; rather, it aims to improve the sector's energy use efficiency.
