“…Apart from EROD, oxidoreductases such as catalase, dehydrogenase and polyphenol oxidase and urease soil enzymes have also been exposed to 10 µg/g TBBPA and BDE-209 (Yu et al, 2017).…”

“…The same behaviour was observed for polyphenol oxidase, where mixtures of compounds produced enzyme inhibition but, independently, CAT activity was slightly induced. The authors concluded that BDE-209 exhibited higher eco-toxicological potential for soil enzymes than TBBPA and demonstrated that inhibition was promoted by BDE-209, TBBPA, Cd and Pb (Yu et al, 2017).…”

Halogenated organic compounds are a particular group of contaminants consisting of a large number of substances, and of great concern due to their persistence in the environment, potential for bioaccumulation and toxicity. Some of these compounds have been classified as persistent organic pollutants (POPs) under The Stockholm Convention and many toxicity assessments have been conducted on them previously. In this work we provide an overview of enzymatic assays used in these studies to establish toxic effects and dose-response relationships. Studies in vivo and in vitro have been considered with a particular emphasis on the impact of halogenated compounds on the activity of relevant enzymes to the humans and the environment. Most information available in the literature focuses on chlorinated compounds, but brominated and fluorinated molecules are also the target of increasing numbers of studies. The enzymes identified can be classified as enzymes: i) the activities of which are affected by the presence of halogenated organic compounds, and ii) those involved in their metabolisation/detoxification resulting in increased activities. In both cases the halogen substituent seems to have an important role in the effects observed. Finally, the use of these enzymes in biosensing tools for monitoring of halogenated compounds is described.

“…Moreover, enzymes are considered to be significant indicators of biochemical processes and the metabolic status of microorganisms in soil [82]. Many studies have studied the effects of amendments and pollutants on soil quality [83]. Urease, phosphatase and catalase activity are the most commonly used indicators to evaluate heavy metal-contaminated soils [84].…”

Effect of Modified Illite on Cd Immobilization and Fertility Enhancement of Acidic Soils

Cadmium pollution in the soil induces significant hazards to agricultural growth and public health. Therefore, new routes are needed to develop low-cost soil amendments that can effectively stabilize cadmium and improve soil fertility. This study introduces modified illite (MIT) with the enhanced ability to stabilize heavy metal Cd through the mixing of illite with calcium carbonate, silicate and sulfate in specific proportions by using the well-known calcination-hydrothermal process. The characterization findings revealed that the modified MIT is predominantly composed of gehlenite and akermanite, with greatly improved specific surface area, pore structure and cation exchange capacity. The main purpose of the present study is to unravel a plausible mechanism on how MIT can stabilize Cd(II) in the soil and to investigate the effect of MIT on the fertility of the contaminated soil. Experiments on soil remediation revealed that MIT has a more profound stabilizing impact on Cd(II) compared to natural illite, resulting in a 22.84% reduction in acid-soluble Cd of the soil when MIT was dosed at 0.5%. The potential mechanism of Cd(II) immobilization by MIT involves the ionic exchange of Cd2+ with the exchangeable Ca2+ and Mg2+. In addition, the hydrolysis products of gehlenite and akermanite are prone to form silicate precipitates with free Cd, leading to soil pH increment. The pot experiments showed that MIT significantly reduces the cadmium content of soil and improves the growth of water spinach organs. Meanwhile, enhancement of the indicators in rhizosphere soil further proved that MIT effectively increases the nutrient content, improves the soil structure and promotes microorganism growth.
