Polluted Water And Cancer Of The Spleen: Is There A Link?

Several studies have found a link between polluted drinking water and cancer. Contaminants in water supplies include pesticides, fertilizers, and heavy metals such as arsenic, radium, and uranium. These contaminants have been linked to an increased risk of bladder, liver, lung, kidney, and colorectal cancer. While the specific effects of each contaminant vary, ingestion of polluted water has been associated with an overall higher risk of cancer. Non-Hodgkin's Lymphoma (NHL), a cancer affecting the lymphoid tissue and other organs of the immune system, has also been linked to contaminated drinking water, particularly in women and children.

This paragraph introduces the topic of the link between polluted water and cancer, with a specific focus on the potential for polluted water to cause cancer of the spleen. It provides an overview of the various contaminants found in water supplies and their associated health risks, as well as the demographic groups that may be particularly vulnerable to the development of cancer as a result of exposure to contaminated water.

Arsenic in drinking water is linked to spleen cancer

Arsenic is a naturally occurring element, so it is impossible to avoid it completely. It is a natural component of the earth's crust and is widely distributed throughout the environment in the air, water, and land. It is highly toxic in its inorganic form.

People are exposed to elevated levels of inorganic arsenic through drinking contaminated water, using contaminated water in food preparation and irrigation of food crops, industrial processes, eating contaminated food, and smoking tobacco. Long-term exposure to inorganic arsenic, mainly through drinking water and food, can lead to chronic arsenic poisoning and cancer. The International Agency for Research on Cancer (IARC) has classified arsenic and arsenic compounds as carcinogenic to humans.

The types and quantities of carcinogens present in drinking water at the point of consumption will differ depending on whether they result from contamination of the source water, arise as a consequence of treatment processes, or enter as the water is conveyed to the user. Source-water contaminants of concern include arsenic, asbestos, radon, agricultural chemicals, and hazardous waste. Of these, the strongest evidence for a cancer risk involves arsenic, which is linked to cancers of the liver, lung, bladder, and kidney.

While there is no direct evidence linking arsenic in drinking water to spleen cancer, long-term exposure to arsenic has been linked to multiple cancers, including bladder, liver, lung, and kidney cancer. Arsenic has also been associated with developmental effects, diabetes, pulmonary disease, and cardiovascular disease. In addition, exposure to arsenic in utero and early childhood has been linked to increased mortality in young adults due to multiple cancers, lung disease, heart attacks, and kidney failure.

Uranium and radium in water sources can increase cancer risk

Uranium and radium are among the radioactive elements found in the Earth's crust. Over time, these elements decay and produce "decay products" such as radium and polonium. This process releases energy in the form of gross alpha radiation, which can contaminate groundwater.

While gross alpha radiation cannot be seen, smelled, or tasted in water, it can pose significant health risks if consumed over a long period. Uranium, in particular, has been linked to an increased risk of kidney damage, while radium has been associated with a higher likelihood of bone cancer. These health concerns highlight the importance of regular testing for uranium, radium, and gross alpha radiation in drinking water, especially for those relying on well water or natural springs.

The potential presence of these contaminants in water supplies underscores the necessity of testing and monitoring to ensure safe drinking water. The Health Department in Vermont, for example, recommends that individuals test their well or spring water sources for uranium and gross alpha radiation every five years. Specialized kits are available for this purpose, allowing for the detection of these harmful elements and the subsequent implementation of necessary precautions to safeguard public health.

It is important to note that the effects of these contaminants are typically observed over extended periods and at high exposure levels. While immediate health risks may not be apparent, the cumulative impact of consuming water contaminated with uranium and radium can lead to an increased risk of cancer and other health issues. Therefore, proactive measures, such as regular testing and, if necessary, the implementation of treatment processes to remove or reduce these contaminants, are crucial to mitigate potential health hazards.

Chlorinated water may be linked to non-Hodgkin's lymphoma

Non-Hodgkin's lymphoma (NHL) is a cancer of the lymphoid tissue and other organs of the immune system. Both adults and children are susceptible to NHL, although treatments differ. Several studies have explored the link between polluted drinking water and the onset of non-Hodgkin's lymphoma, with some scientific experts suspecting that contaminated drinking water may be an underlying factor.

In 1979, the National Institute of Environmental Health Sciences published findings from several studies in Woburn, Massachusetts, that indicated a strong link between chlorinated volatile compounds in drinking water and the instance of cancer, especially leukaemia and non-Hodgkin's lymphoma, in children. Similarly, research has increasingly drawn connections between non-Hodgkin's lymphoma and the water supply at Camp Lejeune, a U.S. Marine Corps base in North Carolina. From 1953 to 1987, military personnel, their families, and civilian staff unknowingly drank water tainted with hazardous chemicals, with one of the resulting grave health concerns being non-Hodgkin's lymphoma.

The use of chlorine for water treatment to reduce the risk of infectious disease may account for a substantial portion of the cancer risk associated with drinking water. The by-products of chlorination are associated with an increased risk of bladder and rectal cancer, possibly accounting for 5000 cases of bladder cancer and 8000 cases of rectal cancer per year in the United States. However, the effects of raised nitrate and nitrite levels in drinking water are currently unclear, with some studies finding a positive association with the risk of non-Hodgkin's lymphoma, while others found no association after adjusting for pesticide use.

Water treatment processes can introduce carcinogens

The use of chlorine for water treatment to reduce the risk of infectious diseases may account for a significant portion of the cancer risk associated with drinking water. Chlorination by-products are associated with an increased risk of bladder and rectal cancer, potentially causing 5,000 and 8,000 cases per year in the United States.

In addition to chlorination by-products, other carcinogens may be introduced during water treatment, including arsenic, asbestos, radon, agricultural chemicals, and hazardous waste. Arsenic, for example, is linked to cancers of the liver, lung, bladder, and kidney.

While most water systems in the United States operate within government standards, the legal limits for contaminants have not been updated in decades. This means that even acceptable levels of contaminants may pose health risks, particularly over the long term.

Furthermore, the presence of disinfection by-products (DBPs) in drinking water has been linked to an increased risk of bladder cancer. DBPs are formed when disinfectants, such as chlorine, react with organic matter in the water. This suggests that the treatment process itself can introduce carcinogens into the water supply.

Therefore, it is important to recognize that water treatment processes can indeed introduce carcinogens, and ongoing research and updated standards are necessary to mitigate potential health risks.

Heavy metals in water can cause acute and chronic toxicity

Water pollution is a pressing issue that affects people worldwide. Heavy metals in water are a significant contributor to this problem and can have detrimental effects on human health, causing both acute and chronic toxicity. These metals enter water bodies through various human activities, including industrial production, mining, agriculture, and transportation. Some common sources of metal pollution are fossil fuel burning, smelting, municipal waste, fertilizers, pesticides, and sewage.

Heavy metals, such as arsenic, cadmium, and chromium, can accumulate in water sources over time, posing severe health risks to those who consume the contaminated water. Long-term exposure to these metals has been linked to various cancers, including skin, lung, bladder, liver, kidney, and colorectal cancer. Additionally, heavy metals can cause acute and chronic toxicity, leading to a range of adverse health effects, such as neurological damage, renal injuries, cardiovascular disorders, and an increased risk of diabetes.

The toxicity of heavy metals in the human body can manifest in multiple ways. They can reduce energy levels, disrupt brain functioning, and damage various organs, including the brain, lungs, liver, and kidneys. Heavy metals can also hinder blood composition and physical, neurological, and muscular functioning. Continued exposure to these metals can increase the risk of developing diseases like multiple sclerosis, Parkinson's disease, muscular dystrophy, and Alzheimer's disease.

The effects of heavy metal contamination are not limited to humans. Aquatic ecosystems are also vulnerable to the harmful impacts of these pollutants. Heavy metals can cause growth inhibition in fish larvae, leading to smaller sizes and reduced competitiveness for food and habitat. Additionally, a decrease in water pH due to acid rain or other acidic incidents can further exacerbate the toxicity of heavy metals, causing aquatic biota to become poisonous.

To address the health risks posed by heavy metals in water, continuous monitoring and regular assessments of metal levels in the environment and human populations are necessary. It is crucial to adhere to the recommended drinking water standards set by regulatory bodies to minimize the potential adverse health effects of heavy metal exposure.
