The synthetic chemical components test of sunscreen, such as benzophenone, are harmful to marine environments. It has been proven that plant oils (olive, jojoba, carrot seed, aloe, avocado, grapeseed and coconut) have the characteristics of ultraviolet absorption. The oils were mixed with the commonly used physical sunscreen materials (titanium dioxide and zinc oxide powder) to develop a self-made sunscreen. It has been proven that the sunscreen produced can achieve satisfying sun screening effect and can serve as substitute sunscreen formula of the current chemical-based sunscreen to reduce the chemical additive pollution of the marine ecosystems.
The aim of the research is removal of metals from contaminated groundwater via chemical reaction between the aquifer rocks and oxalic acid injected in the water. The research consisted of laboratory experiments demonstrating that the concentration of lead, zinc, nickel, barium in the water could be decreased. Further experiments are needed to better understand the appropriate conditions for the success of the method for various metals, and for conditions prevailing in groundwater.
Oil spills can cause serious damage to the resources of the fishing sector and the aquaculture through physical contamination, toxic effects on fish and shellfish populations and by interruption of business activities. In some cases, the application of effective protection measures and cleaning can prevent or minimize damage. As a result of this, ideas arise to seek possible solutions. This is how our research tries to contribute to the ecosystem, capturing the hydrocarbons present in the Coasts of Caldera, with the use of human hair filters (FCH) in artisanal fishing vessels.
The amalgamation of both hydro-electricity and microplastic filtration is an area that is currently unexplored. Our project provides a new alternative ultimately making sustainable energy even more environmentally friendly. Both concepts combined, meet several of the UN’s sustainable development goals. We have optimised our target market to appeal to both LIC’s (Lower income countries), where clean energy will elevate living conditions, and to the HIC’s (Higher income countries), who are the largest production point of microplastics. With minimal prevention of contamination of bodies of water for both locations from household wastewater, our product will tackle this due to its promise of clean energy in a world currently prioritising sustainable energy and the prevention of plastic pollution.
This innovation was developed to improve biochemical properties of biochar as adsorbent called Magnetic Fluid Biochar (MFB) for removal of heavy metal, microplastics and dyes from wastewater. MFB can absorb more than 83% of all types microplastics, 95% of all heavy metals and 90% of all dyes. The result of water treatment in natural water, found that MFB can absorb contaminants more than 90%, which the pH, TSS, TDS and turbidity had been improved up to Surface Water Quality Standards. Therefore, MFB is a high absorbent of contaminants from wastewater with low price 0.02 $/g/L of wastewater. It is an eco-friendly absorbent due to the best synthesized method. It can be reused up to 22 times and recycled to supercapacitor.
The objective of this study was to find out whether microplastic particles can be found at 8 locations in the Upper Engadine with different population densities, types of land use, and distances to the source of the river Inn at Lake Lunghin, a remote location in a major European watershed.
A wooden, low-cost, light, easily transportable self-constructed LADI-trawl was used for sampling. Plastic residues were detected in all locations, and the found particles were assigned to 22 different types of plastics, showing that seemingly remote regions and sparsely populated areas are affected by microplastic pollution. The findings of this research are of key importance for alpine regions, as evidence of plastic was found at over 2400 meters above sea level.
Water is an inevitable aspect of not only humans but all living beings. On the other hand, contamination of water results in many acute and chronic illnesses in humans, and environmental pollution. In this study, the iron oxide particles were synthesized in a simple aqueous-based technique using the seed extract of Syzygium cumini as the source of both reducing and capping agent. These particles show the magnetic character therefore, an external magnetic field was applied to separate the particle from the solution. The kinetic study showed that particles removed 92% of Cd ion in 30 minutes from wastewater. Moreover, this research revealed that the synthesized particles could be a very promising material to remove Cd ion from the wastewater.
Heavy metal pollution from wastewater poses a significant health risk. Conventional methods of heavy metal removal from wastewater use a coagulant to attract metal ions into sludge. The treatment is long, costly and results in large water loss, and is harmful to the environment. In this study, a novel metal filtration system for wastewater using alginate, an algae-derived polysaccharide which forms a hydrogel with metal ions and traps them in place, is introduced. Using the motion of electrophoresis, the metal cations are moved through a compartmentalized alginate liquid filter and is separated based on their affinity toward alginate, making recycling more viable. The practicality of this method is that the resulting material is more eco-friendly and less water and metal are disposed.
