Bus,car and airplane run on fuels derived from petroleum and when they burn to generate power to drive vehicles they produce poisonous gases which cause air pollution 

The dramatic melting of the world’s mountain glaciers – from the Alps to the Himalayas – is mostly the result of man-made global warming rather than natural variability in the climate, a study has found.An assessment of about 200,000 glaciers in the world, some of which have been monitored since the mid 19th century, has found that about two thirds of the current rate of glacial melting is due to human influences on the climate

Natural gas is a versatile, clean-burning, and efficient fuel that is used in a wide variety of applications. It can be used in the form of compressed natural gas (CNG) or liquefied natural gas (LNG) to fuel cars and trucks.  Natural gas as a vehicle fuel is much cheaper and environmentally cleaner than petroleum products.

LPG or Liquefied Petroleum Gas is basically used in households as a fuel for cooking.

Wastewater effluent treatment is important way to control pollutants reaching in water bodies.

• Dissolved oxygen is the amount of free oxygen present in water which is not bound to any other element.
  
• If there is an increase in pollution rates dissolved oxygen rate drops drastically affecting aquatic life.
  

Acid rains: when the concentrations of oxides of nitrogen and sulphur increases in the air, rain water gets mixed up with these oxides to form acid rains.

Among the given options all are apt for the effects of acid rain except that it causes damage to the septic system.

It cannot cause damage to the septic system because most of the septic systems are underground and polluting such system with acids do not cause any adverse reaction to the environment.

Accelerated chemical weathering of building materials, damage to forests and crops, damage to aquatic organisms are the immediate effects of acid rains

A virus is a simple submicroscopic parasite of plants, animals, and bacteria in well water that can cause disease. It consists essentially of a core of RNA or DNA surrounded by a protein coat. Viruses are not living organisms and are unable to replicate without a host cell. Some viral infections often associated with drinking or bathing in contaminated water include:

Gastroeneritus – Causes diarrhea, nausea, vomiting, fever, and abdominal pain.

Cryptosporidiosis – Causes flu-like symptoms, diarrhea, weight loss, bloating, and nausea.

Water pollution can be defined as alteration in physical, chemical or biological characteristics of water, making it unsuitable for designated best use in its natural state.  

World Health Organization (WHO) has defined water pollution as inclusion of any foreign material either from natural or other sources into a water body, thereby changing the natural qualities of water and making it unusable for its intended purpose.

Industrial pollution contaminates many sources of drinking water, releases unwanted toxins into the air and reduces the quality of soil all over the world. Major environmental disasters have been caused due to industrial mishaps, which have yet to be brought under control. From the given options, electronics industry does not spread water pollution.

Radioactive pollution primarily impacts health, contributing to the rise of illnesses such as lung cancer, skin cancer and thyroid cancer, along with birth defects and cognitive disabilities. The type and severity of effects from radioactive pollution vary, depending on the quantity of pollution and amount of exposure. Long-term exposure might cause an increase in the number of genetic birth defects and mutations in a population, while acute exposure poses health risks, such as higher incidences of cancer within a population.

Noise is unwanted sound. A sound which has unpleasant effects and discomfort to ears is called as noise. Generally sound generated by vehicles, horns, loudspeakers, planes, construction etc. are reasons of noise pollution.

The effect caused by industries, railways, explosions, and commotion in the cities, aircraft, etc., can be felt on animals and birds. Noise emissions caused by supersonic aircraft, railway noise emissions etc may cause miscarriage in mammals, fishes, and birds.

Noise pollution affects both health and behavior. Unwanted sound (noise) can damage psychological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.

Sound becomes unwanted when it either interferes with normal activities such as sleeping, conversation, or disrupts or diminishes one's quality of life.
