“…The extraction purity of chloroform was approximately 99.2%, thereby highlighting the impressive adsorption selectivity of the 4L1-Zn@NR film toward chloroform (Figure 6c). The concentration of chloroform solution was monitored over time using 1 H nuclear magnetic resonance (NMR) spectroscopy, revealing a significant decrease in the chloroform concen- tration from 0.075 to 0.00036 g/L, indicating an efficient extraction of chloroform by the sql-4L1-Zn@NR film (Figures S3 and S4 of the Supporting Information). Furthermore, the low intensity of the 1 H NMR signal when the chloroform− water mixture was passed through the pure NR film underscores the inherently low extraction capacity of NR toward chloroform (Figures S5 of the Supporting Information).…”

“…Chloroform is a commonly used organic solvent in pharmaceuticals, synthetic raw materials, and other industrial applications. − However, the use of chlorine for disinfection can result in the formation of chloroform, which is a volatile organic contaminant that is only slightly soluble in water . Chloroform can also be transformed into hazardous and toxic substances, such as phosgene and hydrogen chloride .…”

Chloroform is a volatile organic solvent and a contaminant that is slightly soluble in water, making the reversible separation of chloroform from water a critical and challenging task within the chemical and environmental industries. In this study, we present a newly developed coordination framework, [Zn(4-pmntd)(opa)] [4-pmntd, N,N′-bis(4pyridylmethyl)naphthalene diimide; opa, o-phthalic acid], which demonstrates a high adsorption capacity for chloroform (2.5 mmol/g) and an excellent ability to separate chloroform from water. The effectiveness of chloroform extraction by Zn(4-pmntd)(opa) was confirmed through vapor sorption, grand canonical Monte Carlo simulation, and 1 H nuclear magnetic resonance spectroscopy. The porous framework was also utilized to create a filtration film using natural rubber, which successfully separated chloroform from water with a minimum test concentration of approximately 1 × 10 −6 mol/L and a chloroform purity of 99.2%. [Zn(4-pmntd)(opa)] therefore has significant potential for lowenergy separation and recycling of chloroform from water under ambient conditions.

“…Chloroform (trichloromethane, CHCl 3 ) has been observed in the environment over many years; in air [1], water [2] and soil pores [3]. It is also presented in treated potable water [4][5][6], indeed misinterpretation of the significance of this chloroform content led one government health authority to stop treating drinking water with disastrous consequences [7].…”

“…In the course of this, the effects of the chloroform flux induced by human activity should be placed into the context of the overall ecotoxicological and human health effects arising from the total flux. Significant use has been made of the comprehensive prior assessments of Zok et al [2] and an expanded version of this paper, containing details of all the determinations used, has been reported by Euro Chlor [8].…”

A novel nanocomposite bioadsorbent rectorite/chitosan was prepared by controlling different mass ratios of chitosan to rectorite using the water phase intercalation technique. The structure of the bioadsorbent was characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM), Transmission electron microscopy (TEM), respectively. The results showed that the chitosan had been inserted into the rectorite layer successfully. The adsorption properties of the nanocomposite adsorbent toward CHCl 3 from aqueous solution were investigated. Adsorption results showed that both nanocomposite adsorbents with weight ratio of rectorite to chitosan of 3:1 and 5:1 exhibited higher adsorption capacities.

Bisphenol A (BPA) is a high production volume compound primarily used to produce epoxy resins and polycarbonate plastic. Exposure to low concentrations of BPA occurs in freshwater and marine systems, primarily from wastewater treatment plant discharges. The dataset for chronic toxicity of BPA to freshwater organisms includes studies on fish, amphibians, invertebrates, algae, and aquatic plants. To broaden the dataset, a 1.5-generation test with sheepshead minnow (Cyprinodon variegatus) and a full life-cycle test with mysid shrimp (Americamysis bahia) were conducted. Testing focused on apical endpoints of survival, growth and development, and reproduction. The respective no-observed-effect concentration (NOEC) and lowest-observed-effect concentration (LOEC) values of 170 and 370 mg/L for mysid and 66 and 130 mg/L for sheepshead were based on reduced fecundity. The hazardous concentrations for 5% of the species (HC5) values of 18 mg/L were calculated from species sensitivity distributions (SSDs) with freshwater-only data and combined freshwater and marine data. Inclusion of marine data resulted in no apparent difference in SSD shape, R 2 values for the distributions, or HC5 values. Upper-bound 95th percentile concentrations of BPA measured in marine waters of North America and Europe (0.024 and 0.15 mg/L, respectively) are below the HC5 value of 18 mg/L. These results suggest that marine and freshwater species are of generally similar sensitivity and that chronic studies using a diverse set of species can be combined to assess the aquatic toxicity of BPA.
