The quality of water in the Hindon River in Ghaziabad has improved due to heavy monsoon rains and recent flooding, resulting in higher levels of dissolved oxygen. However, downstream locations still show low levels of dissolved oxygen. The increase in dissolved oxygen is seen as a positive development but its sustainability remains uncertain. The absence of dissolved oxygen in upstream areas may be due to oxygenation as the water flows downstream.
The National Green Tribunal has ordered the Uttar Pradesh Pollution Control Board to submit a detailed report on establishments operating without environmental clearance in Ghaziabad district. The tribunal warned that the UPPCB could be liable for environmental compensation and the officers responsible could be prosecuted for abetting pollution. The UPPCB had previously issued show-cause notices to 20 establishments for operating without consent. However, the NGT found the report submitted by the UPPCB to be unsatisfactory.

Scientists at Dana-Farber Cancer Institute and the Centers for Disease Control and Prevention have uncovered new evidence of the potential health risks of chemicals in tobacco and marijuana smoke.
In a study published online today by
EClinicalMedicine, the researchers report that people who smoked only marijuana had several smoke-related toxic chemicals in their blood and urine, but at lower levels than those who smoked both tobacco and marijuana or tobacco only. Two of those chemicals, acrylonitrile and acrylamide, are known to be toxic at high levels. The investigators also found that exposure to acrolein, a chemical produced by the combustion of a variety of materials, increases with tobacco smoking but not marijuana smoking and contributes to cardiovascular disease in tobacco smokers.
