Illegal Mining on Yamuna Banks

Why in News?

In a joint raid against sand mining mafia the mining department and Loni administration seized earthmovers, trucks, and trolleys from the Yamuna banks in Loni’s Pachera.

Key Points

• A section of land spanning 15 kilometers in Loni along the Yamuna river, encompassing Pachaira, Badarpur, and Nauraspur villages, has been rented out for sand mining.
• The illegal sand mining was happening 1.5km away from the leased 48-acre land in Pachera, which has been rented for a 5-year term.
• To ensure sustainable river sand mining, it is vital to refill the mine pits created during sand extraction through the natural process of replenishment within an appropriate time frame.
  • Illegal deep excavations often occur in sensitive locations along the riverbank, resulting in the formation of deep pits.
• In 2023, flooding in the Loni area caused significant damage, partly due to the deep pits left by illegal sand mining activities along the Yamuna river.

Yamuna River

• About: The Yamuna River is one of the major tributaries of the Ganges in Northern India.
  • It forms an integral part of the Yamuna-Ganga Plain, one of the world's most extensive alluvial plains.

Ozone Levels Breached Safe Limit

Why in News?

According to the Haryana State Pollution Control Board (HSPCB), the ground-level ozone level has exceeded safe limits in certain areas of the city over the past 15 days.

Key Points

• Data from air monitoring stations in Manesar, Sector 51, and Gwalpahari indicate multiple instances of surpassing the 100 micrograms per cubic meter (ug/m3) eight-hour ozone limit.
• Experts have characterized the situation as concerning, noting that the existence of ground-level ozone indicates increased levels of other pollutants such as nitrogen oxide (NOx) and sulphur oxide (Sox).
• These pollutants interact with sunlight to produce ozone, with this phenomenon predominantly happening during the day in locations experiencing traffic congestion or where multiple industries are active.
• Tropospheric ozone exposure poses health risks and can worsen conditions like asthma and chronic obstructive pulmonary disease.
• Officials from HSPCB stated that they have instructed local authorities to take steps to reduce road dust and burning of garbage.

Ozone

• Ozone (composed of three atoms of oxygen) is a gas that occurs both in the Earth’s upper atmosphere and at ground level.
• Ozone can be “good” or “bad” for people’s health and the environment, depending on its location in the atmosphere.
