2018-04-06

The Measures for Management of Soil Environment in Agricultural Land (Trial, Nov. 01, 2017, China) recently came into effect and highlighted the proper management of contaminated croplands to lower risks of exceedances of contaminants, especially toxic trace ...

Tetracycline resistance gene tet(M) of a marine bacterial strain is not accumulated in bivalves from seawater in clam tank experiment and mussel monitoring

10.1016/j.scitotenv.2018.03.305

2018-04-05

Antibiotic resistance genes (ARGs) are found in marine as well as terrestrial bacteria. Bivalves are known to accumulate chemical pollutants and pathogenic microbes, however, the fate of ARGs in bivalves after the intake of ARG-possessing bacteria is not know...

Comment on: “Synchronizing biological cycles as key to survival under a scenario of global change: The Common quail (Coturnix coturnix) strategy” by Nadal, J., Ponz, C., Margalida, A.

10.1016/j.scitotenv.2018.03.322

2018-04-03

Nadal et al. (2018) recently reported on changes in the phenology of the Common quail (Coturnix coturnix) in seven cloudy regions of Spain in relation to climate change. The authors used a long-term ringing database (1961–2014) and calculated the mean date fo...

Mobile dynamic passive sampling of trace organic compounds: Evaluation of sampler performance in the Danube River

10.1016/j.scitotenv.2018.03.242

2018-03-30

A “dynamic” passive sampling (DPS) device, consisting of an electrically driven large volume water pumping device coupled to a passive sampler exposure cell, was designed to enhance the sampling rate of trace organic compounds. The purpose of enhancing the sa...

Application of a short term air quality action plan in Madrid (Spain) under a high-pollution episode - Part I: Diagnostic and analysis from observations

10.1016/j.scitotenv.2018.03.149

2018-03-29

Exceedances of NO2 hourly limit value (200 μg·m−3) imply the need to implement short term action plans to avoid adverse effects on human health in urban areas. The Madrid City Council applied the stage 3 of the NO2 protocol during a high-pollution episode und...

Nitrite ion mitigates the formation of N-nitrosodimethylamine (NDMA) during chloramination of ranitidine

10.1016/j.scitotenv.2018.03.181

2018-03-28

Ranitidine (RNT) has been an important tertiary amine precursor of N-nitrosodimethylamine (NDMA) in chlorine-based water treatment, due to reaction with monochloramine (NH2Cl) with exceptionally high molar yields up to 90%. This study examined the effects of ...

Use of an improved high-throughput absolute abundance quantification method to characterize soil bacterial community and dynamics

10.1016/j.scitotenv.2018.03.201

2018-03-28

High-throughput sequencing has dramatically expanded our understanding of bacterial communities based on the information of the species types and their relative abundances. Recently, researchers have also become aware of a deficiency in not considering the ab...

Nitrogen balances of innovative cropping systems for feedstock production to future biorefineries ☆

10.1016/j.scitotenv.2018.03.155

2018-03-28

Future biorefineries will prefer crops with high biomass yields, thus may precipitate fundamental changes to the agricultural landscape and the biomass production systems. Understanding the fate of nitrogen (N) in novel agricultural land uses is vital for pro...

Refractory organic matter in coastal salt marshes-effect on C sequestration calculations

10.1016/j.scitotenv.2018.03.120

2018-03-28

The age and ability of salt marshes to accumulate and sequester carbon is often assessed using the carbon isotopic signatures (Δ14C and δ13C) of sedimentary organic matter. However, transfers of allochthonous refractory carbon (CRF) from the watershed to mars...

Determination of tylosin excretion from sheep to assess tylosin spread to agricultural fields by manure application

10.1016/j.scitotenv.2018.03.216

2018-03-28

Antibiotics administered to livestock are partly excreted with urine and feces. As livestock excrement is used as manure on agricultural fields, soil may be contaminated by excreted antibiotics, potentially resulting in the development of antibiotic-resistant...
