Integrating toxicity reduction strategies for materials and components into product design: A case study on utility meters
Using RIO Tronics utility meter products as an industrial case study, the numeric Fraunhofer Toxic Potential Indicator (TPI) assessment tool is employed to determine high impact materials with the aim of reducing the content of inherently toxic substances in these products. However, because product re‐design with alternative materials affects entire components, overall component toxicity ...

PAHs, nitro‐PAHs, hopanes and steranes in lake trout from the Lake Michigan
This study examines concentrations and risks of polycyclic aromatic hydrocarbons (PAHs), nitro‐PAHs (NPAHs), steranes and hopanes in lake trout collected in Lake Michigan. A total of 74 fish were collected in two seasons at three offshore sites. Σ9PAH concentrations in whole fish ranged from 223 to 1,704 pg/g wet weight (ww), and PAH concentrations and profiles were similar across season, site ...

Furthering the derivation of predictive wildlife toxicity reference values for use in soil cleanup decisions
The development of media‐specific ecological values for risk assessment includes the derivation of acceptable levels of exposure for terrestrial wildlife (e.g., birds, mammals, reptiles, and amphibians). Though the derivation and subsequent application of these values can be used for screening purposes, there is a need to identify toxicological effects thresholds specifically for making ...

Halogenated carbazoles induce cardiotoxicity in developing zebrafish embryos (Danio rerio)
Halogenated carbazoles are increasingly identified as a novel class of environmental contaminants. However, no in vivo acute toxicity information of those compounds was available. In the current study, an in vivo zebrafish embryonic model (Danio Rerio) was used to investigate the developmental toxicity of those halogenated carbazoles. The results suggested that acute toxicity was ...

Magnetite nanoparticles influence the ammonium-oxidizing bacteria activity during nitritation process
With nanotechnology dissemination, nanomaterials' (NMs) release into the environment is inevitable and may adversely affect the wastewater treatment processes. Among the NMs, the iron oxide nanoparticles have a considerable commercial potential, mainly because their magnetic properties, high catalytic ability and antimicrobial activity. However, few studies have examined their potential ...

Prioritization of pharmaceuticals for potential environmental hazard through leveraging a large scale mammalian pharmacological dataset
The potential for pharmaceuticals in the environment to cause adverse ecological effects is of increasing concern. Given the thousands of active pharmaceutical ingredients (APIs) which can enter the aquatic environment through human and/or animal (e.g., livestock) waste, a current challenge in aquatic toxicology is identifying those that pose the greatest risk. Because empirical toxicity ...

International harmonization of models for selecting less toxic chemical alternatives: Effect of regulatory disparities in the US and Europe
The desire to reduce human exposure to toxic chemicals associated with consumer products that are marketed globally demands the creation of comparative toxicity assessment tools that are based on uniform thresholds of acceptable risks and guidelines for materials use across international boundaries. The Toxic Potential Indicator (TPI) is a quantitative model based on European Union (EU) ...

Two-year meeting schedule, initial chemicals for IRIS discussions announced By EPA
The Environmental Protection Agency released Aug. 9 a two-year schedule of public meetings for its Integrated Risk Information System program and the names of three chemicals for which it will release analytic materials prior to the first meeting (78 Fed. Reg. 48,674). The IRIS program reviews the human health hazards of chemicals and the dose-levels that could trigger harmful effects. EPA's ...

Passive samplers for chemical substance monitoring and associated toxicity assessment in water
The European legislation, and in particular the Water Framework Directive requires the development of cost efficient monitoring tools that can provide the required information for the assessment of water contamination. Passive sampling methods represent one of the novel tools that have a potential to be used in various regulatory monitoring programmes aimed at assessing the levels of chemical ...

EPA Revises Water Quality Criteria
Tens of thousands of members of the regulated community from industrial facilities with air emissions and wastewater discharges to municipal wastewater treatment plants, to hazardous waste site managers may be affected by changes to the WQC. US EPA Water Quality Criteria (WQC) which attempt to protect human health and the environment associated with the US waters, serve as the basis for most ...

Legal lookout: California to control chemicals of concern
Eighth-largest economy in the world drafts regulations to give itself power to control the chemical content of public products. California has a well-established reputation as a trendsetter, but the gargantuan state may have outdone itself with the June 23 draft regulation released from the California Department of Toxic Substances Control (DTSC) for safer consumer product alternatives. The ...

Washington: California is setting precedent
The California Department of Toxic Substances Control (DTSC) released on June 23, 2010, draft regulations implementing California’s precedent-setting and game-changing Green Chemistry Initiative. Manufacturers need to understand how this controversial regulatory program may operate, and why it will alter forever the way consumer products are designed and manufactured. Overview of Draft ...

Alberta Tier 1 Soil and Groundwater Remediation Guidelines
The Alberta Tier 1 Soil and Groundwater Remediation Guidelines are developed and updated by Alberta Environment and Parks through the legislative basis provided by the Water Act(Government of Alberta, 2000) and the Environmental Protection and Enhancement Act(Government of Alberta, 2006). The Tier 1 guidelines are generic and were created to protect sites that are found on the more sensitive side ...

VOCs in HAZMAT and the power of PID detection
An emergency response organisation will greatly increase its effectiveness and the level of protection it offers its employees (Responders) by deploying a photoionisation detector (PID). Incidents Involving VOCs Many Hazardous Materials incidents involve volatile organic compounds (VOCs), a vast chemical family that is primarily made up of hydrocarbons such as gasoline, alcohols, methane and ...

Monitoring the aquatic toxicity of mosquito vector control spray pesticides to freshwater receiving waters
Pesticides are applied to state and local waterways in California to control insects such as mosquitoes, which are known to serve as a vector for West Nile Virus infection of humans. The California State Water Resources Control Board adopted a National Pollutant Discharge Elimination System General Permit to address the discharge of pesticides to waters of the United States resulting from ...
