The Interstate Technology and Regulatory Council published its Vapor Intrusion Toolkit in January 2026. The Toolkit consolidates three earlier ITRC documents into one resource: the 2007 VI-1 guidance, the 2014 PVI-1 petroleum guidance, and the 2021 VIM-1 mitigation ...

Intrinsyx planted 300 hybrid poplar trees as 12-inch cuttings. Within a year, the benefits of using our PDN3 bacterial endophyte to inoculate trees were visible, exhibiting a TCE tolerance phenotype. By using phyto-forensics sampling of tree cores, we showed that the inoculated trees had a thousand-fold less TCE ...
Tree bark samples were collected from 15 sites across Western China in 2013, and the polybrominated diphenyl ether (PBDE) and new polybrominated flame retardant (NBFR) concentrations in the samples were determined. ...
The result was tremendous stress on forests as trees already troubled by insects and disease struggled to hold water. ...

Willow tree bark samples from urban and rural sites in Inner Mongolia, Ningxia Province, and Gansu Province, in the Yellow River basin, were analyzed for polybrominated diphenyl ethers (PBDEs), dechlorane plus (DP), and dioxin‐like polychlorinated biphenyls (DL‐PCBs) to compare their relative levels in air in these areas (i.e., treating bark as a passive air ...
The authors measured soil and litterfall Hg at 15 forest sites (northern hardwood to mixed hardwood/conifer) throughout Vermont, USA, to examine variation among tree species, forest type, and soils. Differences were found among the 12 tree species sampled from at least two sites, with Acer pensylvanicum having significantly greater litterfall ...
Monitoring these elements is important in order to observe and document the damage on plants caused by environmental pollution. The samples consist of leaves and needles collected from different types of trees. ...
The present study focused on the use of cypress tree bark as an environmental indicator of heavy metal deposition in Fuheis City, Jordan, and the evaluation of the impact of emissions from the cement industry in the adjacent environment. Tree bark samples were collected from four directions (north, south, east and west) in the vicinity of the ...
Estimates of peak summer groundwater transpiration rates for the poplar grove range from 12 to 21 gallons per day per tree (gal/day–1/tree-1) (45 to 80 L/day–1/tree-1) based on sap flow measurements and later substantiated by meteorological data and groundwater modeling analyses. The poplar trees induce upward gradients towards ...
