Answer» The sources and effects of domestic and industrial pollutants. | Pollutants | Sources | Effects | | Domestic | | Sodium sulphates and phosphates | Detergents | In humans they cause developmental, reproductive and neuro toxicity and endocrine disruption.

This leads to a decrease in animal and plant diversity. | | Plastic fibres and microbeads | Plastic clothing and hair, beauty and skin products | These end up in water bodies such as lakes ,rivers and the ocean.

It accumulates in the food chain and impacts the top predators the most. | | Nitrates and Phosphates | Fertilisers | Bacteria and algae grow faster and they use up all the dissolved oxygen and this leads to a decrease in animal and plant diversity. | | Industrial | | Lead, Mercury, Cadmium Chromium and Arsenic | Chemical, textile and leather industries and leachate from open dumping of solid waste | Toxic to animals, plants and bacteria in the water.
