Glycol ethers (Ge) are a family of substances with a growing use in industrial and domestic products for the two last decades. Ge (group 1 and 2) are experimentally toxic for reproduction and development, at various levels. That begins to be found in humans. Epidemiological studies confirm toxicokinetic data showing humans are more sensitive than animals, because of a low excretion rate of the toxic metabolites. Occupational and consumer exposures are frequently higher than reference concentrations deducted from animal data. They may be involved in the growing number of genital reproductive system and reproduction anomaly, observed in most developed countries. Genetic toxicity is suspected from experimental data, but further investigations are needed.

Preparation of a novel RAM-MIP for selective solid-phase extraction and gas chromatography determination of heptachlor, endosulfan and their metabolite residues in pork.
Anal Methods
November 2017
College of Environmental and Chemical Engineering, Nanchang Hangkong University, Nanchang 330063, China.
A novel method was established using a restricted access material combined with a molecularly imprinted polymer (RAM-MIP) as the sorbent material in solid phase extraction (SPE) for clean-up of α-endosulfan, β-endosulfan, endosulfate, endosulfan-ether, endosulfan lactone, heptachlor, heptachlor--epoxide, and heptachlor--epoxide in pork and gas chromatography (GC) for determination. The RAM-MIP was prepared by precipitation polymerization by using endosulfan as the template, methacrylic acid (MAA) as the monomer, glycidyl methacrylate (GMA) as the pro-hydrophilic co-monomer, ethylene glycol dimethacrylate (EGDMA) as the crosslinker, azobisisobutyronitrile (AIBN) as the initiator, and toluene as the porogen. Ultraviolet spectroscopy (UV) and H-nuclear magnetic resonance (H-NMR) analysis verified that MAA interacted specifically with endosulfan in a ratio of 1 : 1 in the pre-polymerization solution.

Department of Pharmacology and Toxicology, Center for Human Toxicology, University of Utah, 30 S. 2000 E., Room 201 Skaggs Hall, Salt Lake City, UT, 84112, USA.
Background: Climate change and human activities have caused the drying of marine environments around the world. An example is the Great Salt Lake in Utah, USA which is at a near record low water level. Adverse health effects have been associated with exposure to windblown dust originating from dried lakebed sediments, but mechanistic studies evaluating the health effects of these dusts are limited.

ACS Appl Mater Interfaces

Universite de Pau et des Pays de l'Adour, E2S UPPA, CNRS, IPREM, 64053, Pau, France.
The photopolymerization-induced microphase separation (photo-PIMS) process involving a reactive polymer block was implemented to fabricate nanostructured quasi-solid polymer electrolytes (QSPEs) for use in lithium metal batteries (LMBs). This innovative one-pot fabrication enhances interfacial properties in LMBs by enabling nanostructuring of QSPE directly onto the electrodes. This process also allows for customization of QSPE structural dimensions by tweaking the architecture and molar mass of poly[(oligo ethylene glycol) methyl ether methacrylate--styrene] (P(OEGMA--S)) macromolecular chain transfer agent.

Osseointegration is a crucial property of biomaterials used for bone defect repair. While titanium is the gold standard in craniofacial surgeries, various polymeric biomaterials are being explored as alternatives. However, polymeric materials can be bioinert, hindering integration with surrounding tissues.

The bacterial reverse mutation test is essential for identifying the mutagenic potential of chemicals. The solubility of the test substance is vital for achieving the recommended assay concentration. Preferred solvents like dimethyl sulfoxide and water are chosen for their compatibility and historical data.
