What You'll Learn
Laundry detergents
Detergents are surface-active agents that produce stable and copious foams in rivers, forming a thick and dense layer over the water surface, extending over hundreds of meters. These foams are unhygienic and can be a source of domestic water contamination. The chemicals in detergents are often toxic and include heavy metals like cadmium, arsenic, and lead, which can cause serious health issues such as lung and heart disease and cancer. These toxic substances can contaminate drinking water, fish in rivers and ponds, and the air, posing risks to both human and wildlife health.
Phosphates, a common ingredient in detergents, can build up in waterways and lead to eutrophication. This causes large algal blooms that deplete oxygen levels, harming fish and other plant life. Additionally, the oxygen-reducing substances in detergents can cause severe damage to aquatic life, and the anthropogenic components, such as herbicides and pesticides, can further increase water toxicity.
The use of laundry detergents contributes to water pollution not only through the chemicals they contain but also due to their inability to completely biodegrade. This non-biodegradability leads to the contamination of water supplies, rivers, and oceans, posing ecological and human health risks.
To minimize the impact of laundry detergents on water pollution, it is essential to opt for environmentally friendly and biodegradable alternatives. These eco-friendly options can help reduce the presence of toxic substances in water bodies and mitigate the negative consequences for the environment and human health.

Cigarettes and cigarette lighters
Cigarette butts are the most frequently littered item in US beaches, waterways, roadways, and storm drains. In 2021, over 1 million cigarettes or cigarette filters were removed from American beaches and inland waterways, and it is estimated that 766,571 metric tons of cigarette butts are discarded into the environment annually. Cigarette butts are made of plastic filters that do not biodegrade, causing them to pile up on shorelines or at the bottom of bodies of water. These butts leach toxic chemicals, including nicotine, into the water, soil, and air, and are harmful to wildlife. The chemical byproducts of tobacco product use contaminate wastewater effluents, landfill leachates, and urban storm drains.
The waste from other smoking items, such as cigarette packages and lighters, further contributes to the problem. Single-use plastic lighters add to the plastic pollution associated with cigarettes, and their chemical release rates for water and air are not well-characterized.
E-cigarettes are also a growing problem, with their waste containing plastic, electronic, and chemical components. E-cigarette cartridges discarded on streets break down into microplastics and chemicals that flow into storm drains and pollute waterways and wildlife. The popularity of e-cigarettes is leading to an increase in electronic waste, with millions of devices being thrown away each year.
The tobacco industry's carbon footprint from production, processing, and transportation is significant, contributing to global warming. The environmental impact of the tobacco industry has been likened to that of the commercial airline industry, with tobacco products being the most littered item on the planet.

Vegetable oil
Water is a "universal solvent", meaning it can dissolve more substances than any other liquid on Earth. This makes it extremely vulnerable to pollution. Vegetable oil is one such pollutant, and it can have a detrimental impact on the environment when it is spilled or improperly disposed of.
When vegetable oil is spilled or improperly discharged into water systems, it can cause depletion of oxygen levels, leading to the suffocation of aquatic life. It is considered a noxious liquid substance, and its discharge is hazardous to both marine resources and human health. The International Convention for the Prevention of Pollution from Ships (MARPOL) includes vegetable oils under Category Y, recognising the potential harm they can cause to marine life and human health.
Scientific research and experience with actual spills have shown that spills of vegetable oil can have devastating impacts on the aquatic environment, similar to those of petroleum oil spills. Vegetable oil spills can kill or injure wildlife, leading to hypothermia, dehydration, diarrhoea, or starvation. The coating of oil on aquatic animals can also cause them to suffocate due to oxygen depletion in the water.
Additionally, vegetable oil waste can contaminate soil and affect plant growth. Studies have shown that even low concentrations of vegetable oil waste can inhibit root elongation in plants, impacting their ability to absorb water and nutrients from the soil. This contamination can have far-reaching consequences for agriculture and ecosystems that depend on healthy soil and plant life.
To mitigate the environmental impact of vegetable oil pollution, proper disposal and spill prevention are crucial. Regulations such as the Clean Water Act 1973 and Oil Pollution Act 1990 in the US aim to prevent and control vegetable oil spill incidents. By following these regulations and disposing of vegetable oil waste responsibly, we can minimise the harmful effects of this pollutant on our water systems and the environment as a whole.

Phosphorus in soaps
Phosphorus is one of the primary nutrients for plant growth. It is also an essential nutrient in aquatic ecosystems, where it supports the growth of algae and aquatic plants, which provide food and habitat for fish and other organisms.
Before 1993, phosphates were commonly used in laundry detergents as "builders" to support detergent action by softening the water (removing calcium and magnesium). The wastewater carried the phosphorus to rivers, lakes, streams, and ponds, leading to massive and harmful algae blooms—a condition known as "eutrophication." The algae depleted the water of oxygen, resulting in the deaths of large numbers of fish and other organisms.
Due to the environmental impact of phosphates, there has been a push for Americans to switch to phosphate-free detergents, soaps, and household cleaners. By 2010, 17 states banned the sale of dishwasher detergents containing high levels of phosphates, and many industries are now reformulating their products with phosphate alternatives.

Pet waste
To prevent water pollution from pet waste, proper disposal is essential. Pet owners should be responsible for picking up their pet's waste and disposing of it in designated receptacles or through appropriate waste management systems. Some local governments have implemented innovative solutions, such as environmentally friendly pet waste disposal systems in parks, which act as miniature septic tanks, turning dog waste into a harmless, ground-absorbed liquid.
It is worth noting that pet waste is not the only household contributor to water pollution. Household chemicals, such as those found in laundry, dish, and car washing soaps, can contain phosphates and other pollutants that are carried into the water system through drains. Additionally, the use of electricity in homes contributes to excess nitrogen in the atmosphere, further exacerbating nutrient pollution.
Overall, pet waste is a significant but preventable cause of water pollution. By properly disposing of pet waste and being mindful of other household sources of pollution, individuals can play a crucial role in protecting water quality and preserving the health of aquatic ecosystems.
