Environmental and health risk assessment is a crucial process in identifying and evaluating the potential hazards that may arise from exposure to various pollutants in the environment. One of the major sources of environmental contamination is the self-burning waste pile, which can have significant impacts on soil quality, air quality, and human health. Self-burning waste piles are often associated with uncontrolled landfill sites, where organic waste materials, such as plastics, rubber, and other waste materials, are disposed of and are set on fire by natural or artificial causes. This paper focuses on the environmental and health risk assessment of soil adjacent to a self-burning waste pile.

Seaweeds are aquatic plants that are found in various coastal and oceanic environments. They are used in various food, pharmaceutical, and cosmetic products due to their high nutrient content and medicinal properties. However, seaweeds have been found to accumulate heavy metals in their tissues, which can have adverse effects on human health. Heavy metal contamination of seaweed can occur due to various anthropogenic and natural sources, such as industrial effluents, sewage, agricultural runoff, and volcanic activity. Therefore, it is essential to monitor the levels of heavy metals in seaweed species to ensure their safety for consumption.

By reducing yields and thereby food availability, the significant effects of global warming projected on crops will ultimately have an impact on not only food security but also feed and food safety, with mycotoxins being one of the most significant food safety risks impacted by climate change. Future shifts in temperature, precipitation, and atmospheric CO₂ concentration are anticipated to increase the risk of mycotoxin contamination of cereal crops in the field and may have an effect on where specific cereals, mycotoxigenic fungi, and their mycotoxins are distributed.

The Montreal Protocol outlawed halogenated hydrocarbons with high ozone depletion potential because of their negative effects on the ozone layer, which protects the planet from ultraviolet radiation. Modern refrigeration, air conditioning, and heat pump systems use greenhouse gases that are subject to the Kyoto Protocol's time-barred permission period. Both the Paris Climate Accord and European Union legislation place a strong emphasis on the gradual phase-out of the use of harmful synthetic refrigerants in order to lessen ozone depletion and reverse the effects of climate change. The use of natural refrigerants has no discernible impact on the amount of Greenhouse Gases (GHG) in the atmosphere. Extensive research is being conducted globally to retrofit and modify existing cooling and heating systems using natural refrigerants.
