Particulate and gaseous air pollutants exceed WHO guideline values and have the potential to damage human health in Faisalabad, Metropolitan, Pakistan.

First-ever measurements of particulate matter (PM, PM, and TSP) along with gaseous pollutants (CO, NO, and SO) were performed from June 2019 to April 2020 in Faisalabad, Metropolitan, Pakistan, to assess their seasonal variations; Summer 2019, Autumn 2019, Winter 2019-2020, and Spring 2020. Pollutant measurements were carried out at 30 locations with a 3-km grid distance from the Sitara Chemical Industry in District Faisalabad to Bhianwala, Sargodha Road, Tehsil Lalian, District Chiniot.

The land use impacts of forestry and agricultural systems relative to natural vegetation; a fundamental energy dissipation approach.

In agriculture and forestry the land use impacts that occur during production are important; including as necessary inputs for life cycle assessments. There are major differences in land use impacts between different forest management approaches and, in future, those forestry systems which deliver ecosystem services while having lower adverse land use impacts will be of greater value. Here we examine the land use impacts of seven contrasting forest management approaches and agricultural cropping systems at five locations in Europe.

The sustainable management and protection of forests: analysis of the current position globally.

The loss of forest area globally due to change of land use, the importance of forests in the conservation of biodiversity and in carbon and other biogeochemical cycles, together with the threat to forests from pollution and from the impacts of climate change, place forestry policy and practice at the center of global environmental and sustainability strategy. Forests provide important economic, environmental, social, and cultural benefits, so that in forestry, as in other areas of environmental policy and management, there are tensions between economic development and environmental protection. In this article we review the current information on global forest cover and condition, examine the international processes that relate to forest protection and to sustainable forest management, and look at the main forest certification schemes.

Elevated CO protects poplar (Populus trichocarpa × P. deltoides) from damage induced by O: identification of mechanisms.

CO concentrations in the Earth's atmosphere will rise to between 550 and 700 μL L by 2100 (IPCC 2001). In much of the world, ozone (O) is the air pollutant most likely to be having adverse effects on the growth of plants. Here we describe the impacts of CO and O episodes (rising to 100 nL L), singly and in mixtures on the growth and physiology of an interamerican hybrid poplar (Populus trichocarpa L.
