I try not to use tap water if at all possible, even though I moved to Portland, OR where they supposedly don’t put fluoride in the water.

Scientists just announced they have created a membrane made from a waste by-product of vegetable oil manufacturing, which can filter out heavy metals from contaminated water.

They discovered that proteins derived from the by-products of peanut or sunflower oil production can attract heavy metal ions very effectively.

The study showed that this process of attraction, called adsorption, was able to purify contaminated water so it meets international drinking standards.

Common properties that are must haves in the turbine oil

Oxidation Stability: Oxidation stability is a chemical reaction that occurs with a combination of the lubricant and oxygen. The rate of oxidation is accelerated by high temperatures, water, acids, and catalysts such as copper. The service life of a lubricant reduces with an increase in temperature.

Viscosity Index: The viscosity index (VI) is an arbitrary, unit-less measure of a fluids change in viscosity relative to temperature change. It is mostly used to characterise the viscosity-temperature behaviour of lubricating oils. The higher the VI, the more stable the viscosity remains over temperature fluctuations.

Filterability: Capable of being filtered or separated by filtering.

Low Sludging Formation Tendency: Having low sludge formation tendency.

Heavy Metal Levels in Abandoned Mining Soil: Zamboanga City

Abstract

The study aimed to determine the extent of heavy metal contamination of Copper (Cu) and Lead (Pb) in the soil from the abandoned mining area in Zamboanga City, Philippines using the 2017 EMB Site Characterization Guidelines. Soil samples were randomly collected from 3 meridional blocks at 2 different soil depths, 0-5cm and 20-25cm. Pb and Cu concentrations, organic matter (OM) percentages, pH and Electrical Conductivity (EC) were analyzed using appropriate equipment across sampling sites. The study revealed that heavy metal content in Block 3 exceeded the maximum allowable concentrations based on WHO standard with an average mean of 3,351.00mgkg-1 Pb and 498.67mgkg-1 Cu at 20-25cm soil depth. Moreover, at 0-5cm soil depth, Block 3 had 4176.33mgkg-1 Pb and 494.67mgkg-1 Cu. Furthermore, soil pH was strongly acidic across all blocks with values of pH 5.0 at Block 1; pH 4.7 at Block 2 and pH 4.1 at Block 3. For EC and OM percentages, results ranged from 183.33 μS/cm to 286.67 μS/cm and 1.81% to 4.05%, respectively. Using Analysis of Variance at P < 0.05, this study further revealed that there is a significant difference of Pb and Cu concentrations in 3 meridional blocks at 0.001. This indicates that heavy metal concentrations present in the soil varies in the 3 blocks. However, in physico-chemical parameters, only organic matter has significant difference in all blocks at P ≤0.01. Based from the findings, it is recommended that counter measures be undertaken to minimize further retrogressive impacts of mine tailings left in the area specifically in Block 3.

Introduction

Abandoned mining sites are significant sources of metal pollution even after centuries due to presence of contaminants in the soil. Toxic metals that remain in the soil and tailing ponds have the potential to travel and contaminate environmental habitats such as soil, water, groundwater, and air. It has the potential to alter soil texture, deplete nutrients, penetrate the food chain, create harmful consequences, and destroy ecological habitat and biological variety, including plants (Conesa et al., 2006; Baker et al., 2010; Rashed, 2010).

Soil pollution by heavy metals is a global environmental issue. Heavy metal contaminants represent a health risk to humans through food chain transfer from soils to crops, prompting increased scientific and public awareness of the issue (Alloway 1995; Oliver 1997; Chen and Lee, 1995; Chen et al., 2000) particularly in the areas close to industrial sites and in the vicinity of mining and smelting plants (Pushenreiter et al., 2005). Heavy metal pollution of soils can also be caused by the parent material's high heavy metal content (Huang, 1962; Reeves, 2003). People living in the area may not be aware of the soil pollution, according to Navarrete and Asio (2011), who cautioned that the risk posed by polluted soils is caused by a lack of awareness of people living in the area, who may not be aware of the presence of these pollutants and their health effects.

This study evaluated the concentrations of heavy metals in soil from abandoned mining area in Barangay Baluno, Zamboanga City. Soils in the surrounding mining areas are probably polluted by heavy metals which could possibly pose high health risks to the adjacent community (Li, 2014). The study area has been abandoned for a decade and this study would like to assess the possible contamination of heavy metals in the soil in the present. It was hypothesized that the soils from the abandoned mining area are highly concentrated with heavy metals. The main goal of this study was to determine the concentration of copper and lead in the soils from the abandoned mining area.

Effective Bioremediation Techniques: A Sustainable Solution for Environmental Cleanup

Bioremediation is a sustainable and cost-effective solution to environmental pollution, using living organisms such as bacteria and fungi to degrade pollutants into harmless compounds. There are various bioremediation techniques, including in situ (at the site of pollution) and ex situ (removing contaminants to treat elsewhere). Other methods include bioventing, biosparging, and use of bioreactors to promote the natural degradation of pollutants.

These techniques can handle a wide array of pollution types including petroleum, heavy metal, pesticide contamination, industrial waste, and landfill leachate. Benefits of bioremediation include its sustainability, cost-effectiveness, versatility, and non-invasiveness.

One company leading the way in bioremediation is Delta Remediation, based in Alberta, Canada. They specialize in applying these techniques to sites polluted with hydrocarbons, pesticides, and industrial waste, and have expanded their operations to Nigeria and Kenya.

Bioremediation thus offers a promising method for environmental cleanup, being both eco-friendly and adaptable to diverse environments. Companies like Delta Remediation are pioneering in this sector, making significant contributions to environmental health.

Landfarm Remediation: The Ancient Art of Healing the Earth

Landfarm remediation is a practice that involves using natural systems and microorganisms to break down and transform harmful substances in contaminated soil and water. This approach seeks to restore the balance of natural systems and promote healing and growth in the environment, while also creating a more sustainable future for human society.

Landfarm remediation is based on the principles of sustainable agriculture and draws upon the ancient art of working with the earth to promote healing and growth. It recognizes the interconnectedness of the health of the land and the health of all living beings, and seeks to work with nature, rather than against it.

To remediate contaminated soil, specific strains of microorganisms are introduced to break down the contaminants and transform them into harmless compounds. This process typically involves soil testing and analysis, tilling and aerating the soil, and adding organic materials such as compost and manure to provide food and energy for the microorganisms.

Landfarm remediation is a complex process that requires careful planning and management, as well as an understanding of the natural systems and microorganisms involved. However, the rewards are significant, including the restoration of the health of contaminated land and the creation of new opportunities for sustainable agriculture and land use.

Ultimately, landfarm remediation is a powerful tool for healing the earth and creating a more sustainable future by combining ancient wisdom with modern scientific knowledge and techniques. It can help us create a world that is healthier, more resilient, and more connected to the natural systems that sustain us.

I know it’s a funny statement and that’s why it became a meme but when you hear “isopods remove heavy metals from soil” it’s not like they’re mining it and putting the contaminants in piles. it goes into their bodies and makes them very sick, and can lead to toxic metal buildup in animals that eat them

have yall ever gotten lead poisoning from all that

Nope. Large Bastard had to get a ton of blood tests, including a heavy metals test, before the transplant and there was nothing elevated - we asked about it specifically and everything was normal; I have lower lead exposure than he does so we haven't done a blood test for me.

The thing is that big chunks of lead is a much lower exposure risk than working with particulate lead, so it's a lot scarier to deal with stuff like lead paint than it is a pot with a gallon of hot liquid lead in it. The people who clean up the bullet blocking material at indoor shooting ranges are dealing with much nastier stuff than people who are loading bullets.

It's a good idea to wear gloves and minimize skin contact when you're working with any lead, and to wear respirators in certain conditions. You certainly shouldn't handle lead if you're not familiar with how to do so safely, and you should definitely be concerned about recalls associated with lead paint or lead contamination in makeup or food products.

A big chunk of lead sitting in your hand for a minute or two once in a while is unlikely to be a problem; lead powder in makeup that you put on your skin or in paint on plates or toys is a big, big problem.
