SGS is pleased to launch its Zero Discharge Holistic Solution, using an assertive approach supported by a diverse range of technical solutions to assist textile and footwear brands and retailers to move a step closer to their zero discharge goal. GENEVA, 26-May-2017 — /EuropaWire/ — The manufacturing of textiles, footwear and leather are intensive in their chemical and water consumption. On a global basis, vast supply chains cross continents and the potential environmental impacts that derive from their chemical usage can be significant. This becomes particularly apparent considering that approximately 9.3 million tonnes of chemicals are consumed annually to manufacture these textile products, and around 25% of chemicals made worldwide go directly or indirectly into the textile industry. Environmental or related product compliance issues can result from inappropriate or overuse of chemicals which may have arisen from a lack of traceability along the value chain. In addition, technical gaps in areas such as upstream chemical management, understanding of chemistry, risk identification and chemical inventories preclude the industry from progressing to chemically and environmentally responsible production. While industry stakeholders have invested much effort in chemical and environmental responsible production, many of these challenges continue to persist. SGS clearly understands each step of the manufacturing process and its associated challenges. Using a holistic approach and its unique global supply chain diagnosis tools, SGS can offer expert advice on ways to effectively manage chemicals at the upstream level and mitigate many of the issues both during production and at the downstream level. With the SGS Zero Discharge Holistic Solution, a vast array of turn-key and customized solutions under the trio approach are available to support the industry to take appropriate actions towards environmentally responsible production. While there is no one-size-fits-all solution, a combination of these highly specialist services can be built and crafted to suit the unique supply chain model and business goal of a specific brand or a retailer to ensure achievable and measureable improvements can be made. Under our trio approach SGS offers: Training & Knowledge Management to upskill industry professionals’ technical knowledge Chemical Risk Assessment to benchmark suppliers’ current chemical and environmental performance Best Practice & System Implementation to identify root causes and to make appropriate recommendations for future improvements SGS has been partnering with many international brands and retailers in support of their zero discharge commitments. Contact your sales representatives to see how we can support your supply chain.

Exposure reconstruction for substances of interest to human health is a process that has been used, with various levels of sophistication, as far back as the 1930s. The importance of robust and high-quality exposure reconstruction has been recognized by many researchers. It has been noted that misclassification of reconstructed exposures is relatively common and can result in potentially significant effects on the conclusions of a human health risk assessment or epidemiology study. In this analysis, a review of the key exposure reconstruction approaches described in over 400 papers in the peer-reviewed literature is presented. These approaches have been critically evaluated and classified according to quantitative, semiquantitative, and qualitative approaches. Our analysis indicates that much can still be done to improve the overall quality and consistency of exposure reconstructions and that a systematic framework would help to standardize the exposure reconstruction process in the future. The seven recommended steps in the exposure reconstruction process include identifying the goals of the reconstruction, organizing and ranking the available data, identifying key data gaps, selecting the best information sources and methodology for the reconstruction, incorporating probabilistic methods into the reconstruction, conducting an uncertainty analysis, and validating the results of the reconstruction. Influential emerging techniques, such as Bayesian data analysis, are highlighted. Important issues that will likely influence the conduct of exposure reconstruction into the future include improving statistical analysis methods, addressing the issue of chemical mixtures, evaluating aggregate exposures, and ensuring transparency with respect to variability and uncertainty in the reconstruction effort. © 2010 Informa Healthcare USA, Inc.

The unique combination of size, structure, morphology, and physical/chemical characteristics of nanomaterials presents challenges to understanding the potential hazards and health risks of engineered nanomaterials. A hierarchical risk ranking framework was developed for two nanomaterials, carbon black and carbon nanotubes, as a case study for industrial and consumer use settings. A numerical risk ranking scheme was derived from product and nanomaterial characteristics, use and exposure patterns, and toxicological information. Primary drivers of risk ranking estimates included releasability from the matrix or system, exposure pathway and intensity, bioavailability, biopersistence and severity of health effects. Evident differences in hazard ranking were observed between nanostructured materials of similar elemental composition but different morphologies. This framework offers a novel strategy to identify and prioritize the hazard and potential health risks of nanomaterials and associated products throughout their lifecycle.

Soluble cobalt (Co) supplements with recommended daily doses up to 1000 μg Co/day are increasingly being marketed to consumers interested in healthy living practices. For example, some athletes may consider using Co supplements as blood doping agents, as Co is known to stimulate erythropoesis. However, the distribution and excretion kinetics of ingested Co are understood in a limited fashion. We used a Co-specific biokinetic model to estimate whole blood and urine Co levels resulting from oral exposure or ingestion of Co in amounts exceeding typical dietary intake rates. Following 10. days of Co supplementation at a rate of 400 to 1000 μg/day, predicted adult Co concentrations range from 1.7 to 10 μg/L in whole blood, and from 20 to 120 μg/L in urine. Chronic supplementation (≥1. year) at a rate of 1000 μg Co/day is predicted to result in blood levels of 5.7 to 13 μg/L, and in urine levels from 65 to 150 μg/L. The model predictions are within those measured in humans following ingestion of known doses. The methodology presented in this paper can be used to predict urinary or blood Co levels following acute or chronic occupational incidental ingestion, medicinal therapy, supplemental intake, or other non-occupational exposures. © 2012 Elsevier Ltd.
