What Happens to Your Body After Breathing Polluted Air for 24 Hours? Imagine you're walking out the door on a hectic morning. The streets are busy, factories are running nonstop, and a thin layer of haze hangs over the city's skyline. You might not realize it right away, but every time you breathe, small amounts of pollution get into your body. Indeed, these elements can start affecting your health just a few hours after exposure. Air pollution has become one of the biggest environmental problems around the world. Health experts say that being around polluted air for a long time can cause serious health problems. But even after just one day of breathing in polluted air, your body can start changing in big ways inside. So, let's look at what happens right from the time polluted air gets into your lungs and how it might affect your whole body. What Is Polluted Air? Contaminated air comprises detrimental substances including: Fine particulate matter (PM2.5 and PM10) Carbon mon...
The Defence Institute of Advanced Technology (DIAT), located in Pune, has received a notice from the Maharashtra Pollution Control Board (MPCB) for allegedly releasing untreated sewage into a nallah that empties into the Khadakwasla Dam. This is a worrying trend. As pollution levels rise, the dam—a crucial source of water for Pune—has come under examination, alarming local authorities and environmentalists.
The Allegations and Findings
The problem was discovered when the irrigation department complained about the dam's water contamination in January 2025. After that, on February 3, 2025, MPCB representatives inspected the area and took water samples from the nallah close to DIAT. The samples' blackish hue, septic condition, and offensive odor were determined to be unmistakable signs of untreated sewage discharge.
According to additional research, DIAT produces about 606 cubic meters of sewage each day, but it lacks a working sewage treatment plant (STP) to handle this waste. Environmental laws, such as the Air (Prevention and Control of Pollution) Act of 1981 and the Water (Prevention and Control of Pollution) Act of 1974, are being directly broken by this. DIAT's location in a designated "Pollution Prevention Area" makes its non-compliance even more concerning.
MPCB's Reaction
The infractions have been duly noted by the MPCB, which has sent DIAT a formal notice. Before more legal action is taken, the institute has been called to an in-person hearing to defend its activities. The MPCB Pune Regional Officer, JS Salunkhe, underlined that DIAT must establish a suitable STP in accordance with environmental standards.Khadakwasla Dam: An Issue With Pollution More Widely
Although DIAT's purported discharge has garnered attention, Khadakwasla Dam's contamination is caused by a number of sources. There have been reports that the dam's catchment region also receives untreated sewage from neighboring communities, hotels, farmhouses, and other establishments. One of Pune's most significant reservoirs has seen its water quality decline as a result of this cumulative contamination.
Concerns about the dam's condition and potential effects on public health have been raised by locals. Agricultural operations that rely on clean water from the dam are also at risk due to the contamination, in addition to drinking water sources.

Action Is Needed Now
The notice sent to DIAT emphasizes how urgently environmental laws surrounding Khadakwasla Dam must be strictly enforced for all establishments and enterprises. Experts recommend a number of actions to deal with the problem:
Installation of STPs: In order to keep untreated wastewater out of water bodies, all facilities producing large volumes of wastewater are required to install sewage treatment plants.
Frequent Monitoring: To find pollution sources, authorities should regularly inspect and check the water quality in the dam's catchment area.
Community Involvement: Through awareness campaigns and participatory monitoring initiatives, local populations should be involved in efforts to safeguard water supplies.
Collaborative Solutions: To create all-encompassing pollution management plans, government organizations, non-governmental organizations, and regional stakeholders must cooperate.
