            |  Reducing Hazardous Chemicals in Consumer Products: Proactive Company Strategies |  Source: Journal of Cleaner Production, December 20, 2012 Author: Caroline E. Scruggs
 Laws governing chemical manufacture and use have historically been weak.  Consequently, many argue that humans and the environment are not  adequately protected from chemicals that could pose a risk to their  health. In this environment of regulatory deficits, some proactive  consumer product companies are voluntarily going beyond regulatory  requirements to minimize use of currently unregulated, but potentially  hazardous, chemicals in their products. These companies generally do not  advertise their chemicals management efforts. Interviews with  environmental managers from 20 multinational consumer product companies  revealed ten common elements of proactive chemicals management  strategies that were relevant and used across sectors. For instance,  companies developed restricted substance lists of regulated and  unregulated chemicals that were banned from their products; worked to  find safer substitutes for chemicals of concern, sometimes through green  chemistry initiatives; created tools to enhance communication through  their supply chains; and required suppliers to provide full materials  disclosure so that they understood the chemical content of their  products. These findings document the best practices for chemicals  management among proactive consumer product companies in the absence of  effective chemicals regulations, and the 20 companies' chemicals  management strategies revealed insights about the gaps in chemicals  regulations and what consumer product companies across sectors need to  fill those gaps. This information may be useful to business and industry  representatives who are interested in minimizing product risks and to  policy makers who may be unfamiliar with companies' challenges in making  safer consumer products or how laws could be strengthened to support  their efforts. The results could also help inform the design of  modernized laws that promote chemicals management in all supply chains  to better protect human and environmental health from hazardous  chemicals.

        |  Counting the cost of mercury pollution |  Source: Environmental Health, January 7, 2013
 Cleaning up mercury pollution and reducing prenatal exposure to the  neurotoxin methylmercury (MeHg) could save the European Union €10,000  million per year, finds a new study published in BioMed Central's open  access journal Environmental Health. New estimates suggest that  between 1.5 and 2 million children in the EU are born each year with  MeHg exposures above the safe limit of 0.58µg/g and 200,000 above the  WHO recommended maximum of 2.5µg/g.   While some mercury occurs naturally in the environment for example  from volcanic eruptions or forest fires, most is generated by burning  fossil fuels. Marine and fresh water species bioconcentrate MeHg;  consequently the main source of exposure for humans is from eating fish.   Read more...    Read article in Environmental Health: "Economic benefits of methylmercury exposure control in Europe: Monetary value of neurotoxicity prevention."       |  
  Study Finds Flame Retardant Pollutants at Far-Flung Locations
  |  Source: Indiana University, January 8, 2013
  BLOOMINGTON, Ind. -- Chemicals used as flame retardants are present  as environmental pollutants at locations around the globe, including  remote sites in Indonesia, Nepal and Tasmania, according to a study by  researchers from the Indiana University School of Public and  Environmental Affairs.
 
 The study, published this month in the journal Environmental Science and Technology,  makes use of a novel but highly effective sampling technique: measuring  concentrations of the chemicals in the bark of trees, which absorbs  compounds in both vapor and particle phases.   Read more...    Read article in Environmental Science and Technology: "Brominated and Chlorinated Flame Retardants in Tree Bark from Around the Globe."     Also in ES&T: "Tribromophenoxy Flame Retardants in the Great Lakes Atmosphere."    |  
 |  Natural Products for Materials Protection: Corrosion and Microbial Growth Inhibition Using Capsicum frutescens Biomass Extracts |  Source: ACS Sustainable Chemistry & Engineering, December 17, 2012 Authors: Emeka E. Oguzie, Kanayo L. Oguzie, Chris O. Akalezi, Irene O. Udeze, Jude N. Ogbulie, and Victor O. Njoku
  Extracts of the fruit of Capsicum frutescens (CF) were assessed  for anticorrosion and antimicrobial activity. The anticorrosion effect  of the ethanol extract on low carbon steel in acidic media was studied  experimentally using gravimetric, impedance, and polarization  techniques, while the antimicrobial efficacy of ethanol, methanol,  water, and petroleum spirit extracts respectively against the  corrosion-associated sulfate reducing bacteria (SRB), Desulfotomaculum species, was assessed using the agar disc diffusion method. CF extract  effectively inhibited both corrosion and SRB growth due to the action of  the phytochemical constituents present therein, including alkaloids  (8.8%), tannins (0.4%), and saponins (39.2%). The corrosion process was  inhibited by adsorption of the extract organic matter on the steel  surface, whereas the antimicrobial effect results from disruption of the  growth and essential metabolic functions of the SRB. Molecular dynamics  (MD) simulations were performed to theoretically illustrate the  electronic structure and adsorption behavior of the active alkaloidal  constituents of CF extract, capsaicin and dihydrocapsaicin, and afforded  molecular level insights on their individual contributions to the  corrosion inhibiting action of the extract.

  Evaluating Green Projects: Modeling Improves Economic Benefits
  |  Source: Chemical Engineering, July 1, 2012 Authors: Allen Williams and Ken Dunwoody
  The ability to model a process to see if it meets project requirements  and is economically viable can help to enhance its conceptual design and  management approval. Modeling allows engineers to identify promising  processes and to weed out less-promising ones. This article walks the  reader through the use of modeling to evaluate an environmentally  oriented (green) engineering project...
