It has been hypothesized that ingestion of microplastic increases exposure of aquatic organisms to hydrophobic contaminants. To date, most laboratory studies investigated chemical transfer from ingested microplastic without taking other exposure pathways into account. Therefore, we studied the effect of polyethylene (PE) microplastic in sediment on PCB uptake by Arenicola marina as a model spec...

Aim: Most studies on the effect of produced water are centred effects physicochemical parameters recipient environment, but not much has been conducted biogeochemical processes such as nitrogen cycle. This study aims to determine median lethal concentration (LC50) that would cause mortality 50% exposed population Nitrosomonas sp. (test organism) which is involved in ammonification step Nitrogen...

The testing and release of genetically modified organisms (GMOs)—in particular GM plants—is tightly regulated internationally to prevent any negative effects on the environment or human health. However, these regulations are based on transgenic organisms and do not discriminate between transgenic plants and cisgenic plants, although we believe that they are fundamentally different (see sidebar)...

Chronic undersampling of the marine environment, including both biological and physical components, has been and remains a major block to understanding how marine ecosystems function and how they respond to changes, whether natural or anthropogenic. Consequently, data-based models that accurately predict local variations in the abundance of plant and animal life in the sea are rare or do not ex...

1. Rabbits injected intravenously with a large dose of a virulent Type III Pneumococcus develop a bacteremia, and within an hour organisms may be cultivated from the thoracic duct lymph. The rapidity with which entrance into the lymph occurs appears to be correlated with the size of the dose injected. 2. The organisms may become more numerous in the lymph than in the blood. 3. If homologous or ...
