 Loading and unloading activities in harbours contribute to noise pollution in sea traffic.

The level of steady noise is measured in decibels (dB).

A variety of old and used articles from various sources. The term "solid waste" refers to a broad range of discarded materials, including old and used articles from various sources such as households, businesses, industries, and institutions. This can include items like paper, cardboard, plastics, glass, metals, food waste, and other materials that are no longer needed or useful and are disposed of as waste. Solid waste encompasses a diverse array of materials and is generated from numerous sources within communities.

Acid rain is mainly caused by sulfur dioxide (SO₂) emissions reacting with water vapor in the atmosphere, forming sulfuric acid.

While iron can be found in water sources, it is not typically considered a heavy metal associated with water pollution.

Trees are not sources of noise pollution. They can actually help reduce noise pollution by acting as natural sound barriers.

Using air purifiers with HEPA filters can help reduce indoor air pollution by capturing particles such as dust, pollen, and pet dander. 

Overcrowding, congestion, and poor sanitary conditions. Urban areas are typically characterized by high population density, leading to overcrowding and congestion. These areas often face challenges related to inadequate infrastructure, such as poor sanitation facilities, which can result in unsanitary conditions. These characteristics are common in urban environments due to the concentration of people and activities within limited spaces.

It has become significant due to the large quantity of waste generated. Solid waste pollution in urban areas has become significant due to the large quantity of waste generated by urban populations. Rapid urbanization and population growth contribute to increased waste production, leading to challenges in waste management and disposal. This pollution can have detrimental effects on the environment, public health, and quality of life in urban areas if not properly managed. Therefore, addressing solid waste pollution is crucial for sustainable urban development.

Land degradation leads to a decline in land productivity, as it affects the soil's ability to support plant growth and agricultural activities.
