Not all pollutants in water are inherently toxic; their effects depend on factors such as concentration, exposure duration, and the specific type of pollutant. Some substances may be harmful at high levels but safe at lower concentrations, while others may be benign. Additionally, the sensitivity of aquatic life and human health to different pollutants varies, influencing the overall toxicity of contaminated water. Therefore, assessment of water quality requires careful analysis of both the pollutants present and their potential effects.
Whenever harmful substances such as sewage, toxic chemicals, silt, etc.., get mixed with the water, the water becomes polluted. The substances that pollute water are called Water Pollutants
Pollutants, toxic materials and chemicals
The Clean Water Act regulates pollutants such as oil and grease, toxic metals, pesticides, and industrial chemicals. These pollutants can come from various sources such as industrial discharges, agriculture runoff, and municipal sewage. The Act sets limits on the amount of these pollutants that can be discharged into water bodies to protect water quality and aquatic life.
because man still makes pollutants

1. Industrialisation has led to the discharge of pollutants and toxic materials in water bodies through drainage into rivers and underground water table. 2.Urbanisation has led to discharge of pollutants like human/animal waste material ,chemicals and toxic materials as sewage discharge into rivers and water bodies. 3. Rural human population and animal waste including chemicals used in pesticides and fertilisers have polluted water sources.
Water pollutants can be categorized into various types, including chemicals, nutrients, pathogens, and sediments. These pollutants can harm aquatic ecosystems by causing water quality degradation, harming aquatic life, and posing risks to human health. Chemical pollutants can be toxic to aquatic organisms, while excess nutrients can lead to algal blooms and oxygen depletion. Pathogens can cause waterborne diseases, and sediments can smother aquatic habitats and disrupt ecosystems. Overall, water pollutants can have detrimental effects on the environment, leading to ecosystem imbalances and reduced water quality.

Oil spills, toxic wastes, and plastics are primarily classified as environmental pollutants. They contaminate air, water, and soil, posing significant risks to ecosystems and human health. These pollutants can disrupt marine and terrestrial habitats, leading to long-term ecological damage and affecting biodiversity. Additionally, they can accumulate in the food chain, posing further risks to wildlife and human populations.
They will always remain toxic. A toxic chemical is a toxic chemical. Cyanide will always have the ability to kill you and will never, not be deadly.
