Effects of Tetrabromobisphenol A on enzyme activity in soil

2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011
Tetrabromobisphenol A (TBBPA) is widely used throughout the world as flame retardant for electronic equipment or building materials, and is detected in air at the dismantling plant, sewage sludge, sediment or human serum samples. In the present study, we examined the effects of TBBPA on soil polyphenol oxidase, catalase and dehydrogenase activity by ...

GENES CODIFYING ENZYMES AND ENZYME ACTIVITIES IN SOIL

2011
The discussion of links between genes codifying enzymes and enzyme activities of soil involves two different philosophical approaches since the classical soil enzymology is based on the holistic approach whereas the molecular approach is based on a detailed knowledge of enzymes involved in the measured enzyme activity.

The Effect of Roxarsone on Soil Enzyme Activities

Applied Mechanics and Materials, 2012
An indoor simulation experiment has been carried out to study the effects of Roxarsone on the soil neutral phosphatase, catalase and urease activity. The result showed that the enzyme activities were reduced by the Roxarsone, and the effect degree was aggravated with the increasing consistency.

Enzyme activities in a limed agricultural soil

Biology and Fertility of Soils, 2000
This study assessed the effect of eight lime application rates, with four field replications, on the activities of 14 enzymes involved in C, N, P, and S cycling in soils. The enzymes were assayed at their optimal pH values. The soil used was a Kenyon loam located at the Northeast Research Center in Nashua, Iowa.

Characterization of soil samples by enzyme activity

Journal of Biological Education, 1977
The presence of extracellular enzymes in soils offers a very sensitive method for matching, or distinguishing between, soil samples. Simple colorimetric methods were used to compare enzyme levels in soils from different sites. It was found that each soil tested had its own spectrum of enzyme activity, by which it could be characterized and thereby ...

[Effects of furadan on soil enzyme activity].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
By using simulation method, this paper studied the effects of furadan on the activities of soil urease, invertase and alkaline phosphatase, with the affecting factors investigated. The results showed that after adding furadan into soil, soil urease activity was decreased first but increased then, indicating that the ecotoxicity of furadan was reduced ...

ENZYME ACTIVITY IN DEVELOPED PEAT SOILS

Multifunctional adaptive fodder production
The article presents the results of a study of the activity of some enzymes from the class of oxidoreductases in the developed peat soils of the Tagan swamp. It was found that the entire profile of the studied soils is biochemically active, which ensures their potential fertility.

[Effects of Hg on soil enzyme activity].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
With simulation test, this paper studied the effects of Hg on the activities of urease, invertase and neutral phosphotase in four soils. The results showed that Hg inhibited soil urease and invertase activities markedly, but its inhibitory effect differed with test soils.
