The pig industry is the most crucial animal industry in Taiwan; 10.7 million pigs were reared for consumption in 1996. A foot and mouth disease (FMD) epidemic broke out on 19 March 1997, and 3,850,536 pigs were culled before July in the same year. The major disposal method of pig carcasses from the FMD outbreak was burial, followed by burning and incineration. To investigate groundwater quality...

Heavy metal contamination around the National Iranian Lead and Zinc Company (NILZ) in Zanjan province was evaluated in this paper. Collected data were used to appraise the degree of soil contamination and also the source of pollution in the study area based on geoaccumulation index (Igeo), and enrichment factor (EF). The levels of Fe, Zn, Cd and Pb in the samples exceed those reported in litera...

Oil leakage causes soil contamination and induces changes in the physical and mechanical properties of soils. In areas contaminated with oil products such as gasoline, the implementation of civilian operations requires determination and prediction of soil behavior in the existing conditions. In this research work, the effect of oil contamination by gasoline obtained from the National Oil Compan...

Background: Soil structure is mainly composed of sand, silt, clay, and organic materials. Organisms can live in the soil. The large number of stray cats in the cities of Iran is a major environmental and health problem. Toxoplasma oocysts are shed with the feces of cats, so soil is known as a potential source of transmission of toxoplasmosis. The aim of this study was to determine the soil cont...

The major reasons for environmental contamination are population explosion, increase in industrial and other urban activities. One of the consequent effect of these activities is heavy metal pollution. It is one of the serious issue to be discussed by the scientists and academicians that how to solve this problem to protect the environment. As heavy metals are non-biodegradable so they require ...

the objective of the study was to determine the effect of the process of natural bioremediation, and bioremediation supported by zb-01 microbiological preparation on the occurrence of collembola and araneae in conditions of soil contaminated by petroleum-derived substances. the studies were conducted in 2010-2012, in the area of the experiment station of the university of agriculture, near krak...

PREMISE OF THE STUDY Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important driver of population dynamics in sagebrush steppe ecosystems, has been altered by exotic annual grass invasion. Soil seed banks may play an activ...
