Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
A biofilter/bio-oxidation system is a fairly simple device to construct and operate and offers a cost-effective solution provided the pollutant is biodegradable within a moderate time frame (increasing residence time = increased size and capital costs), at reasonable concentrations (and lb/hr loading rates) and that the airstream is at an ...
Biological pollution (impacts or bio pollution) is the impact of humanity's actions on the quality of aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species, [ 1 ] otherwise known as Invasive Alien Species (IAS).
Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment. [1] Remediation may be required by regulations before development of land revitalization projects.
The biology department of the United Arab Emirates University investigated dust storm frequencies and strengths on a 5-year time period, between 2004 and 2009, and have ascertained that climate change effects could be the reason for the resultant of a noticeable shift in the characteristics of dust storms. "The range of mineral compositions of ...
[5] [6] Further problem areas are air and water pollution (including nutrient pollution), over-exploitation, invasive species [7] and climate change. [ 4 ] Many scientists, along with the Global Assessment Report on Biodiversity and Ecosystem Services , say that the main reason for biodiversity loss is a growing human population because this ...
Since the founding of Singapore in 1819, more than 95% of its estimated 590 square km of vegetation has been cleared. At first for short-term cash crops and later because of urbanization and industrialization. 61 of its original 91 bird species has been lost leading to many native forest plants not being able to reproduce because of loss of seed dispersal and pollination.
The FBISE was established under the FBISE Act 1975. [2] It is an autonomous body of working under the Ministry of Federal Education and Professional Training. [3] The official website of FBISE was launched on June 7, 2001, and was inaugurated by Mrs. Zobaida Jalal, the Minister for Education [4] The first-ever online result of FBISE was announced on 18 August 2001.
