Joan Mitchell paints a symphony
It's 1983, and American artist Joan Mitchell is in her studio outside Paris, transforming her emotions and memories into a symphony of colors and shapes. Inspired by her friend's description of an idyllic hidden valley in France, Mitchell creates 21 massive paintings--her Grande Vallée series--bursting with vibrant, energizing hues. But she doesn't paint the valley's flowers and meadows. She paints a feeling about them, creating a harmonious blend of drips, splashes, and brushstrokes in rainbow colors. When the paint dries, it's time to share her valley with the world. This picture book about an influential yet lesser-known American artist provides a snapshot of a creator who deserves as much acclaim as fellow abstract expressionists Jackson Pollock or Willem de Kooning. Author Lisa Rogers shares both the despair and delight Mitchell experienced throughout her career, while illustrator Stacy Innerst's artwork captures the movement and energy of Mitchell's work.

Physico-Chemical Analysis of Wastewater Discharge from Selected Paint Industries in Lagos, Nigeria
Effluents from the paint industry have been a major source of environmental pollution. There is a need to investigate the compliance of wastewater discharged from paint industries with regulatory standards. In response, this study evaluates the physicochemical parameters of both raw and treated wastewater, the wastewater treatment plants (WWTPs) efficiencies as well as the compliance level of five selected paint manufacturing companies in Lagos, Nigeria with some regulatory standards: Federal Ministry of Environment (FME) in Nigeria, World Health Organization (WHO) and Department of Water Affairs (DWA) in South Africa. All parameters investigated were analysed using standard methods. The values of pH, electrical conductivity (EC) and total dissolved solids (TDS) levels were in the range of 4–12.2, 149.1–881.3 mS/m and 1100–6510 mg/L, respectively. The range of other parameters include total suspended solids (TSS); 0–2470 mg/L, TS; 1920–6510 mg/L, chloride; 63.8–733.8 mg/L, dissolved oxygen (DO); 0–6.7 mg/L, oil and grease (O & G); 44–100 mg/L, biochemical oxygen demand (BOD); 162.8–974.7 mg/L, chemical oxygen demand (COD); 543–1231 mg/L, nitrates;12.89–211.2 mg/L, phosphate; below detection limit (bdl)–0.02 mg/L, sulphate; 195–1434 mg/L, nickel; bdl–1.9 mg/L while copper, lead and chromium were below detection limits. The results indicated that the WWTPs of the studied paint companies were ineffective in reducing the TS, TSS, BOD, COD and (O & G) to acceptable limits. Routine monitoring of wastewater from paint industries is therefore recommended to prevent the risk of contamination to the receiving watershed which many communities rely on as source for domestic water.

Poly(Vinyl Acetate) Paints: A Literature Review of Material Properties, Ageing Characteristics, and Conservation Challenges
Since their development in the 1950s, poly(vinyl acetate) [PVAc] paints (also known as vinyl) have been used by many artists, most notably in countries such as Spain, Portugal, and the United Kingdom; they are also used globally as a common binder for house paints. However, only a relatively limited number of heritage scientific studies have focused on vinyl paints. Consequently, many critical aspects of this material, such as the degradation processes, variations in paint formulations, and responses to conservation treatments, remain largely understudied. This article aims to summarise the available relevant information on poly(vinyl acetate) paints from both the scientific and the conservation practice perspectives. The article provides a brief overview of the development of poly(vinyl acetate) paints as artist-grade and household products and the known differences in their formulations. It also focuses on poly(vinyl acetate) ageing behaviour, the physicochemical properties, the recent scientific research on poly(vinyl acetate) material characterisation and degradation, and the main conservation issues regarding these paints, such as those relating to cleaning treatments.

Towards Portable One-Drop Voltammetry with Doped Screen-Printed Electrodes to Control Preservatives: A New Tool for Diuron and Isoproturon in the Paint Industry
The use of preservatives such as diuron and isoproturon in the paint industry is essential to protect products against microbial attack. However, these compounds are subject to strict regulation due to the harmful effects they have on the environment and human health. Therefore, analytical strategies to control the production process at paint plants are fundamental to ensure suitable products. In the present work, a low-cost portable square-wave voltammetry device with commercial screen-printed electrodes was proposed to control the starting products and to determine isoproturon and diuron levels in manufactured paint products. Under the optimized conditions (electrolyte HClO4 0.18 M, nickel oxide-doped carbon electrodes, ESW = 0.02 V, Estep = 0.0015 V, and ƒ = 15 Hz), the results indicated satisfactory analytical performance, with detection limits of 3.5 and 3.0 mg L−1 for isoproturon and diuron, respectively, and precision lower than 7.5% for both biocides. The analytical strategy employed to achieve satisfactory selectivity involved taking advantage of the specific interaction of cysteine with 1,2-benzisothiazol-3(2H)-one (BIT) as a potential interferent in some commercial products and the use of matrix match calibration. A recovery study provided values in the range of 92–104% for accuracy validation. A sample pretreatment step was needed due to the paint composition, and a miniaturized method was proposed here. The novelty of this method lies in the use of a portable voltammetry device in real-world industrial applications to control the paint production process using a cost-effective, time-saving, sustainable, and green protocol. The HEXAGON tool is used for assessing greenness and sustainability. The choice of reagents like HClO4 and the minimization of waste from the small volumes used align with the principles of using safer solvents, a key concern in green and sustainable chemistry.

Investigation of the Release Rate of Biocide and Corrosion Resistance of Vinyl-, Acrylic-, and Epoxy-Based Antifouling Paints on Steel in Marine Infrastructures
This study comprehensively assesses the release rate of biocides, corrosion effects related to antifouling, and the physical properties of different paint types. Tests were conducted to measure thickness, viscosity, hardness, bending, adhesion, gloss, impact resistance, abrasion resistance, scratch resistance, polarization, and salt spray. The paints evaluated include resin-based, acrylic-based, epoxy-based, and vinyl-based formulations. The study investigates the influence of biocide content, biocide particle size, and immersion time on release rate using a lab-scale setup. Results showed that acrylic-based paints had a higher biocide release rate due to faster hydrolysis, while smaller biocide particle sizes led to higher release rates in resin-based paints. Optimal total biocide contents were determined to be 30% for acrylic-based, 60% for epoxy-based, and 50% for vinyl-based paints. Antifouling corrosion analysis demonstrated that sample with an optimal release rate effectively prevent algae growth and fouling. Acrylic-based paint with 30 wt.% biocide content exhibited superior adhesion with a dolly separation force of 4.12 MPa. Evaluating the impact of synthesized polyaniline on 30 wt.% epoxy-based paint, a sample coated with 10 wt.% polyaniline represented a low corrosion rate of 0.35 µm/year and a high impedance value of approximately 37,000 Ohm·cm−2.

Restoring Massachusetts' 1930 Tercentenary Signs
Most, however, marked the site of an alleged and seemingly unprovoked attack or other atrocity inflicted upon innocent colonists. [...]instead of creating an opportunity to re-envision the past, the MassDOT decided to refurbish these signs, giving these historical distortions a new lease on life. The final cost of the restoration was apprximately$10,000 per sign. Because each sign required such fastidious hand-detail to restore, labor costs were the primary expenditure. According to Maurice Cassidy, founder and owner of Cassidy Bros. blacksmith shop, the cost to crreate new cast iron molds for new signs could be upwards of $ 20,000 per sign.

Stochastic health risk profiling of potentially toxic elements in Iranian ornamental construction paints: assessing and Monte Carlo simulation
Paints consist of intricate combinations of solvents, additives, and pigments that provide the desired color, coverage, and durability, and pose a human health risk due to potentially toxic elements (PTEs), including lead (Pb), chromium (Cr), and cadmium (Cd), which accumulate in biological systems. This research innovatively assessed the non-carcinogenic and carcinogenic health risks posed by PTEs in Iranian decorative (ornamental) paints and emphasized the need for awareness raising and the development of control regulations. The PTEs concentrations were determined through wet acid digestion and analyzed through ICP-OES. The findings indicated that Pb concentrations ranged from 689.4 to 858.6 mg/kg, Cr concentrations from 698 to 946.4 mg/kg, and Cd concentrations between 0.24 and 0.37 mg/kg, revealing that Pb and Cr values exceeded the permissible limits. The findings suggest that children exhibit a heightened susceptibility to these pollutants due to their unique behaviors and physiological traits. The ingestion route represented the primary contribution to the total hazard quotient, accounting for 96.8% in children and 58.4% in adults. The adults’ hazard index (HI) for Pb and Cd was below the safe threshold of 1, whereas Cr surpassed this limit concerning non-carcinogenic risk. In children, the HI for both Pb and Cr surpassed the acceptable limit. Total Lifetime cancer risk (TLCR) values for both groups in Cr were higher than the acceptable range established by the USEPA, with relatively higher values observed in children. Among the three metals analyzed, Cr exhibited the most significant potential health risk, followed by Pb and Cd. Ingestion was identified as the primary route of exposure, while inhalation and dermal routes were less significant. To enhance the accuracy of exposure risk assessments for PTEs, a Monte Carlo simulation was utilized as a probabilistic algorithm to minimize uncertainties.
