The bottom-up traffic emission model EMISENS is used to calculate hourly black carbon (BC) and nitrogen oxides (NOx) emission rates on an average workday in Maribor (Slovenia), using emission factors that were previously determined with the on-road chasing measurements in Slovenia. From modeled NOx emission rates and in-situ NOx measurements we empirically determined the hourly dispersion of traffic emissions and applied it to model BC concentrations using BC emission rates.

Degrading air quality in metro cities is a matter of concern for public health. Massive tree plantation drives are often conducted in order to provide oxygen to choking cities.

NEW DELHI: Not just extreme heat, air pollution levels are also peaking in many parts of the city.

Soil N is an essential element for plant growth, but its mineral forms are subject to loss to the environment by leaching and gaseous emissions. Despite its importance for the soil-plant system, factors controlling soil mineral N concentrations over large spatial scales are not well understood. We used NH4+ and NO3− concentrations (0–30 cm depth) from 469 sites across Australia, and determined soil controls on their regional variation. Soil mineral N varied regionally but depended on the different land uses. In the agricultural region of Australia, NH4+ tended to be depleted (4.9 ± 4.8 vs.

Taking a cue from the pillar-based vertical gardens in Singapore and Mexico city, the Prime Minister’s Office (PMO) has asked the Ministry of Housing and Urban Affairs, and the Ministry of Environm

This move makes New Delhi the first city in the country to switch from BS-IV grade fuels to BS-VI (equivalent to fuel meeting Euro-VI emission norms).

Efforts have been made in recent years to improve knowledge about soil greenhouse gas (GHG) fluxes from subSaharan Africa. However, data on soil GHG emissions from smallholder coffee-dairy systems have not hitherto been measured experimentally. This study aimed to quantify soil GHG emissions at different spatial and temporal scales in smallholder coffee-dairy farms in Murang'a County, Central Kenya.

The Union Environment Ministry has set emission standards for industries where nitrogen and sulphur oxides are generated as these gases are leading to increase in air pollution and affecting human health.

By applying an inversion algorithm to NOx satellite observations from Ozone Monitoring Instrument, monthly NOx emissions for a 10 year period (2007 to 2016) over Chinese seas are presented for the first time. No effective regulations on NOx emissions have been implemented for ships in China, which is reflected in the trend analysis of maritime emissions. The maritime emissions display a continuous increase rate of about 20% per year until 2012 and slow down to 3% after that.

Total emissions from motor vehicles fell 12% from 2012 to 2016, according to the Office for National Statistics.
