Buyer’s Guide: What is Arsenic?
In literal terms, arsenic is a semimetallic, brittle element with a vibrant grey color found abundantly under Earth’s surface. Arsenic tends to sublimate at standard atmospheric pressure, i.e., it changes its state from solid to gas directly. Arsenic is used for agricultural and industrial purposes and is a byproduct of copper mining, coal burning, and copper smelting.
Effects of Arsenic on Human health
The health effects of arsenic in drinking water are not unfounded. Consuming high levels of arsenic through any means, such as drinking arsenic water, can be detrimental to human health as it affects a wide range of organs and body systems. Short-term and long-term effects of ingesting arsenic compounds or drinking arsenic water are harmful to human beings.
According to the World Health Organization, short and long term exposure to drinking arsenic water causes:
Short-term subjection to arsenic compounds or drinking arsenic water can lead to the following symptoms:
- Vomiting
- Abdominal pain
- Nausea
- Diarrhea, dehydration, and shock
- In extreme cases, it can cause muscle cramping and death.
Long-term subjection to arsenic compounds or drinking arsenic water can lead to:
- Pigmentation in the skin
- Skin legions
- Hard patches on the palm and sole of the feet
- Skin cancer
- Diabetes
- Pulmonary diseases
- Cardiovascular diseases
- Endocrine disruption
Other than the above-stated effects, high arsenic level in drinking water is also known to cause adverse pregnancy consequences such as:
- High mortality rates in young adults who have been exposed to arsenic in early childhood
- Stunted growth of cognitive development, intelligence, and memory in children and young adult
Types of Arsenic
According to IARC (International Agency for Research on Cancer), arsenic can be categorized into three major groups:
- Inorganic arsenic compounds
- Organic arsenic compounds
- Arsine gas
Until the 1970s, inorganic arsenic compounds were utilized to treat leukemia, chronic bronchial asthma, and organic arsenic compounds were utilized in making antibiotics to treat protozoal diseases.
Organic compounds of arsenic are currently utilized in making pesticides for agricultural purposes. Other than this, both of the arsenic compounds are used for:
- To manufacture alloys with copper and lead
- To make semiconductors and electronic appliances
- Arsine is utilized as a doping agent to make crystals for fiber optics and computers.
- To manufacture wood and leather preservatives, pigments, and dyes.
Where does arsenic come from in drinking water?
The health effects of arsenic in drinking water are serious and fatal. Every public water source has to be tested for the maximum arsenic contaminant level as outlined by WHO. But let’s look at the occurrences of arsenic and its compound in the environment:
- Natural Occurrence: Arsenic occurs in mineral species such as sedimentary iron and manganese. The abundance varies from 5mg/kg to 2900mg/kg.
- In Water: The amount of arsenic in surface water sources is less than 10microg/L but can reach up to 5g/L. In groundwater sources, the concentration of arsenic is high due to sulfide deposits, but in the regions like China, Bangladesh, and Taiwan, the groundwater is highly contaminated with arsenic due to consistent coal mining and copper smelting.
- Fertilizers: According to the Centers for Disease Control and Prevention, High arsenic levels in drinking water or private wells may be due to fertilizers, herbicides containing arsenic, or industrial waste used in the past.
- Dietary exposure: The highest concentration of arsenic is found in seafood. Other than fish and mussels, arsenic is also found in dairy products, cereals, and vegetables.
How to detect arsenic in water?
According to WHO guidelines, arsenic maximum contaminant level in drinking water should not exceed 10 μg L−1. If arsenic maximum contaminant level exceeds 10micro L-1, it needs to be removed and filtered out using an arsenic purifier. Currently, to detect arsenic in drinking water, a small-scale arsenic water test kit is utilized. The arsenic water test kit is used as follow:
- Every arsenic water test kit requires a different sample size and reagents to halt the interference of other substances such as hydrogen sulfide ions.
- A plastic bottle reaction vessel is used to collect the reagents.
- A test strip is used and placed above the reaction vessel in a specific cap.
- Arsenic converts into arsine gas and comes in contact with the strip.
- Now, the mercuric bromide indicator changes color. If arsenic is present, the color change will be from white to shades of brown and yellow.
- Lastly, the strip color change is compared against a comparator charge to determine the quantity of arsenic present in the drinking water.
Best technology to remove arsenic at home
Many water filters that remove arsenic are available in today’s market but here are the best technologies, which are inexpensive, easy ways to filter arsenic from water
- OXIDATION: it involves the conversion of arsenite or arsenate. Oxidation is a crucial step for arsenic water treatment in the ground. This arsenate can be oxidized by atmospheric oxygen, but this is a slow process. Catalysts such as bacteria can be useful in arsenic removal from drinking water.
- COAGULATION: coagulation involves treating arsenic levels in drinking water by adding CaO, that is, lime. Calcium hydroxide acts as a flocculant for arsenic and helps in arsenic removal from drinking water.
- MEMBRANE TECHNIQUES: one of the techniques for arsenic water treatment is reverse osmosis that requires a membrane. These membranes are semi-permeable and can remove maximum arsenic in drinking water by force. The other membranes can decrease the arsenic maximum contaminant level by ultrafiltration and microfiltration.
Ultimate Guide: To buy the best water filter for Arsenic removal from the drinking water.
The considerations that need to be kept in mind while buying water filters that remove arsenic are detailed below for your convenience:
Water source/removal of contaminants
One of the most important considerations to keep in mind is whether your water filter removes the contaminants you specifically want to eliminate. To lower the arsenic in drinking water, you need to consider the water filters that remove arsenic with special arsenic water filter cartridges.
For example, the FrizzLife SK99 water filter is highly precise with a 0.5-micron filter, efficiently removing lead, chlorine, chloramine, fluoride, and other harmful substances.
Pre and post-filtration
Water filters that remove arsenic have pre and post-filtration systems to ensure efficiently clean and fresh water. These are important to purify drinking water to the maximum level.
Installation
A pivotal point while choosing water filters that remove arsenic is that the filters have an easy installation. If not, then it becomes costly and burdensome to do so.
Flow rate and water pressure
Another important factor to look for before choosing the best water filter for yourself is the flow rate and water pressure. Most of the time, the best filters with multiple-stage filtration have a decreased flow rate and pressure, which could be a nuisance.
The greater the water pressure, the faster the flow rate will be. Consider one of the best water filters that remove arsenic and other contaminants with a better flow rate and maximum pressure to meet the needs of households.
Production and wastage rate
Production and wastage rate has to be considered when buying one of the water filters that remove arsenic. Some systems waste a lot of water compared to their production. To prevent wastage and ensure maximum water production, choosing a system with mechanisms and storage tanks is important to minimize water waste.
Replacement of filters
You need to have select one from the water filters that remover arsenic that easily replaces filter cartridges and long-term durability. If this is not the case, then the sustenance of the filter system becomes costly.
Environment friendly
When it comes to buying products, it is your responsibility to make informed choices that do not harm the environment. The most suitable countertop water filters that remove arsenic, purify drinking water should have a better taste, be crispy, and be more delicious than bottled water.
Cost-effective
Cost-effectiveness is another key factor to consider when shopping for water filters that remove arsenic. A longer filter life significantly lessens the time needed to invest in the maintenance of the arsenic removal systems.
