This study was carried out using indoor controlled experiments to study the arsenic uptake, biotransformation, and release behaviors of freshwater algae under growth stress. Three freshwater algae, Microcystis aeruginosa, Anabaena flosaquae, and Chlorella sp.,Two types of inhibitors, Cu²⁺ and isothiazolinone, inhibit the growth of the algae. The algae were cultivated to a logarithmic stage in growth media containing0.1 mg/L P; then,0.8 mg/LAs in the form of arsenate (iAs^V) was added,while both inhibitors were simultaneously added at dosages of 0.1 and 0.3 mg/LAfter 2 days of exposure, the average growth rate was measured to represent the growth rates of the algae cells; the extra- and intracellular monomethyl arsenic, and di-Me arsenic, were also measured,Without inhibitors,M.aeruginosa significantly higher than that of the other two algae.However, when Cu²⁺ was added as an external inhibitor, the order of the average growth rate for the three algae became partially reversed.The great reduction in M. aeruginosa growth rate was accompanied by increases in extracellular iAs^V and iAs^III and intracellular iAs concentrations The biol.productivity of As by the three algae followed the order of M.aeruginosa, Chlorella sp.,and A.flosaquae,generally consistent with the As transformation and release in conditions with and without inhibitors, suggesting that the As behavior in the algae that was related to growth stress largely differed among algae species. In the experiment, the researchers used many compounds, for example, Isothiazol-3(2H)-one (cas: 1003-07-2Quality Control of Isothiazol-3(2H)-one).

Electro-kinetic washing of a soil contaminated with quinclorac and subsequent electro-oxidation of wash water was written by Vidal, J.;Baez, Maria E.;Salazar, R.. And the article was included in Science of the Total Environment in 2021.Related Products of 1003-07-2 This article mentions the following:

This work deals with the remediation of a soil that has been enriched with Quinclorac (QNC), one of the herbicides most used in Chile for weed control in rice fields. Quinclorac damages the microflora and macrofauna of soils and is toxic to some susceptible crops, which results in economic loses during crop rotation. Furthermore, Quinclorac a potential contaminant of water resources and soils, given its high mobility and persistence. This has created the need to lower its concentrations in soils intensively cultivated. In this study, an electro-kinetic soil washing system (EKSW) for mobilizing this pesticide in the soil was explored. The performance of this technol. was compared by assessing the effect of direct (DP) and reverse (RP) polarity during 15 days under potentiostatic conditions and applying an elec. field of 1 V cm-1 between electrodes. Among the main results, the highest removal of QNC was obtained through the EKSW-RP process, which also contributed to the prevention of acidity and alk. fronts in the soil, compared to the EKSW-DP system. In both cases, the highest accumulation of QNC occurred in the cathodic well by mobilizing the non-ionized contaminant through the electroosmotic flow (EOF) from anode to cathode. After the treatment with EKSW, the wash water accumulated in the anodic and cathodic wells, which contained an important concentration of pesticide, was subjected to electro-oxidation (EO) by applying different current densities (j). The high generation of •OH on the surface of a boron-doped diamond electrode (BDD) allowed for the complete degradation and mineralization of QNC and its major intermediate compounds to CO₂. The results of this study show that the application of both coupled stages in this type of remediation technologies would enable the removal of QNC from the soil without altering its chem. and phys. properties, constituting an environmentally friendly process. In the experiment, the researchers used many compounds, for example, Isothiazol-3(2H)-one (cas: 1003-07-2Related Products of 1003-07-2).

Isothiazol-3(2H)-one (cas: 1003-07-2) belongs to isothiazole derivatives.

Long-lasting isothiazolinone-based biocide obtained by encapsulation in micron-sized mesoporous matrices was written by Mardones, Lucas E.;Legnoverde, Maria S.;Pereyra, Andrea M.;Basaldella, Elena I.. And the article was included in Progress in Organic Coatings in 2018.Product Details of 1003-07-2 This article mentions the following:

The physicochem. properties of the silicas (structure, textural properties) were evaluated by SEM, TEM, XRD and adsorption/desorption of N₂ in order to determine their ability to encapsulate, stabilize and subsequently release a com. biocide used for latex preservation (CMIT/MIT). CMIT/MIT consists of an aqueous solution of the active ingredients CMIT (5-chloro-2-methyl-4-isothiazolin-3-one) and MIT (2-methyl-4-isothiazolin-3-one), present in a CMIT/MIT: 3/1 wt ratio. MCF has less hindered diffusion caused by a short channel length, which facilitates the biocide access to the pores of the matrix. The long pore length of SBA-15 makes the diffusion of CMIT/MIT mixture more difficult. Biocide release tests in aqueous media indicated that the CMIT/MIT concentration in the leaching solution depends on the matrix nature, the smaller values being obtained when the ordered matrix was used. Addnl., biocide delivery could be delayed by increasing the working pH from 7 to 9. Results showed that biocide encapsulation allows maintaining a long-lasting release, even under alk. conditions (pH 9), at which the hydrolysis of non-supported CMIT occur. Several release tests at different temperature (318, 323 and 328 K), were carried out for 20 days at pH 7. The biocide loading after the tests was reflected in the IR spectra, and it has been corroborated that biocide encapsulation allows retarding the fast thermal decomposition of CMIT. In the experiment, the researchers used many compounds, for example, Isothiazol-3(2H)-one (cas: 1003-07-2Product Details of 1003-07-2).

Modeling mould growth on coated modified and unmodified wood substrates exposed outdoors was written by Gobakken, Lone Ross;Lebow, Patricia K.. And the article was included in Wood Science and Technology in 2010.Product Details of 1003-07-2 This article mentions the following:

Mold growth on coated wood is today a genuine challenge for house owners. Environmentally sound wooden facades with long service lives and acceptable appearance are desired. The objective in this study was to investigate the accumulated mold growth on 13 different wood substrates with 3 surface coating systems by identifying the factors that contribute to the variation and to predict future performance. A generalized linear mixed model was fit to the data with the anal. showing that coating and exposure time both had highly significant influences on mold growth. Further, wood substrate was significant, but comparatively less than coating and exposure time. A smaller coefficient for mold coverage in the beginning of the exposure period gave the panels with one of the coating systems, BAP, a delay in mold growth, and the extrapolated values for years 6-12 indicate a longer aesthetic service life than panels with the two other coating systems. Coated heartwood as wood type was less susceptible to mold growth than coated mixed wood and coated sapwood. Acetylated pine as wood substrate and aspen as wood species had lower resistance to mold growth than the other wood substrates and wood species, resp.

Isothiazolinone has been widely used in circulating cooling water system as an effective broad-spectrum fungicide. Due to the instability of isothiazolinone itself in the application, magnesium salt as stabilizer is usually added in I type products (14%). Application of isothiazolinone with magnesium salt as stabilizer in the closed water system can affect the total hardness of the water system. So bromine compound organic compounds as stabilizer have been developed, and the application of isothiazolinone with bromine compound organic compounds as stabilizer has no significant influence on the water quality parameters of the system, which is beneficial to the stable operation of the system.
