edi tor ’s note: NEHA strives to provide up-to-date and relevant information on environmental health and to build partnerships in the profession. In pursuit of these goals, we feature a column from the Environmental Health Services Branch (EHSB) of the Centers for Disease Control and Prevention (CDC) in every issue of the Journal. In this column, EHSB and guest authors from across CDC will high...

EPA Region 5 expects to post in August 2014 a full and open solicitation for environmental dredging in Great Lakes' rivers and harbors and handling of dredged sediments, NAICS code 562910. EPA anticipates 5-year, multiple-award, indefinite-delivery, indefinite-quantity type contracts with firm-fixed-price task orders, at an estimated value of $300 million per contract. GLNPO executes a budget o...

or consisting of one story, but well elevated and flued, and inhabited by the Europeans, is a flat spot of ground, intersected with ditches, and containing much jungle, along with indigo and paddy fields, reaching close upon the premises surrounding the habitations. On the north side is an inconsiderable branch of the Ganges, having little communication with the parent river, and which, except ...

Water resource problems currently are much more important in proper planning especially for arid regions, such as Gansu in China. For agricultural and industrial activities, prediction of groundwater status is critical. As a main branch of neural network, shallow artificial neural network models have been deployed in prediction areas such as groundwater and rainfall since late 1980s. In this pa...

Historical DNA of museum specimens is paramount importance in elucidation complex nomenclature issues and a priceless source material gathered during preceding centuries hardly accessible today sites. Here we report the results genotyping type Lemmus obensis bungei Vinogradov, 1925 from collection Zoological Institute RAS lemmings upper streams Omolon River, identified as L. amurensis Systemati...

During the Southern Great Plains experiment, the synthetic aperture radiometer, ESTAR, mapped L-band brightness temperature over a swath about 50 km wide and about 300 km long extending west from Oklahoma City to El Reno and north from the Little Washita River watershed to the Kansas border. ESTAR flew on the NASA P-3B Orion aircraft at an altitude of 7.6 km and maps were made on 7 days between...

In this study, atmospheric moisture source regions and transport pathways, which substantially affect extreme summer precipitation events in the region of Yellow River (SRYR) China were investigated using Lagrangian Flexible Particle Dispersion Model (FLEXPART). Based on 24-hour cumulative data from Meteorological Data Service Center, 2012 2015 selected to represent wet dry years during period ...

We investigated the distribution of HBCD in the Japanese river sediment and compared them with the estimated concentration. High concentrations of HBCD were detected in the Japanese river, which receives the textile wastewater at concentrations of 134-2061 ng/g. This contrasts with the results from the Japanese urban river, where HBCD concentrations (0.8-4.8 ng/g) were comparable to those in th...
