Field dissipation and plant uptake of benzotriazole ultraviolet stabilizers in biosolid-amended soils

Abstract

a Benzotriazole ultraviolet stabilizers (BUVSs) have been commonly used in industrial and household product formulations, and have been detected in biosolids from wastewater treatment plants. However, little is known about their occurrence and dissipation behavior in the soil environment associated with biosolid application. This study investigated the occurrence and dissipation of five typical BUVSs (UV-326, UV-327, UV-328, UV-329 and UV-P) in biosolid-amended soils, and the uptake of these biocides by plants.The field trial includes two treatment groups: old groups with biosolid application at rates of 5, 10, 20 and 40 t ha À1 every year within 5 years, and new groups with only one biosolid application. The resultsshowed that the five BUVSs could be detected in most biosolid-amended soils at a few to tens of ng g Environmental impactBenzotriazole ultraviolet stabilizers (BUVSs) are widely used as additives in paints, coatings, adhesives, polymeric surfaces, food packing lms and construction materials. They have been detected in biosolids from wastewater treatment plants. With application of biosolid to agricultural land, these chemicals may contaminate the agricultural soils and thus affecting the terrestrial ecosystem and human health. BUVSs (UV-326, UV-327, UV-328, UV-329 and UV-P) could be detected in the biosolid-amended soils at a few to tens of ng g À1 levels. This one year monitoring study demonstrated slow dissipation of the BUVSs in soil environments.

Syntheses, Structures, and Fluorescent Properties of ­Lanthanide Complexes Based on the Ligand Benzotriazole‐5‐carboxylic Acid

“…It shows that complex 2 gives no fluorescent emissions, while complexes 1 and 3 give characteristic emissions of Eu III and Tb III ions, respectively. As shown in Figure 4, there are two emission peaks of 591 and 615 nm in complex 1, which can be distributed to 5 [28,29] and can be used to sensitize the fluorescent property of Eu complex. The quantum yield was measured in an absolute photoluminescence quantum yield spectrometer.…”

“…[1][2][3] Derivatives of benzotriazole are important ultraviolet absorbing compounds. [4][5][6] Furthermore, there are at least three nitrogen atoms in these compounds, which are potential coordination sites and can coordinate to metal ions in versatile modes. Benzotriazole-5-carboxylic acid (H 2 btca) is the simplest derivative of benzotriazole.…”

Benzotriazole UV Stabilizers (BUVSs) in the Environment: Much More than an Emerging Contaminant of Concern

“…BUVs enter the environment through a variety of pathways. Some of them include: i) through wastewater treatment plant (WWTP) e uents; ii) plastic debris and or via weathering of outdoor plastics and products coated with BUVs; iii) personal care products (PCPs) containing BZTs as an additive (Lai et al, 2014a;Braush and Rand, 2011). The rst occurrence of phenolic BZTs compounds was reported in the 1980s by Jungclaus et al, (1978) and Avila and Hites, (1980).…”

The “Periodic Table” of 1-methylbenzotriazole: Zinc(II) Complexes

“…Benzotriazoles are central "players" in organic [2,3,6], medicinal [7,8], environmental [9], physical and theoretical [4,[10][11][12][13][14], and materials [15][16][17][18][19][20][21][22] chemistry from both the basic research and applications viewpoints. For example, in materials chemistry: (a) polar benzotriazoles (including BtaH) are used as corrosion inhibitors for metals (especially Cu) and their alloys, in antifreeze liquids, household detergents, aircraft de-icing fluids, and in the treatment of artifacts of historical and archaeological importance [15][16][17]; (b) BtaH and its amino-, azido-, and nitro-derivatives are being tested as energetic materials [18][19][20]; (c) orthohydroxyphenyl benzotriazoles find extensive use as UV absorbers (stabilizers) in plastic materials, personal care products, and biosolids [21,22]; and (d) benzotriazole-decorated grapheme oxide is a very efficient material for removal of the uranyl ion from nuclear waste water [23]. Benzotriazole-and benzotriazolate-based ligands are also important in inorganic chemistry [24,25].…”
