The researchers found that dichloromethane levels in the stratosphere have nearly doubled since 2004.
2
The reaction was less efficient in acetonitrile than in dichloromethane.
3
The procedure involves liquid-liquid extraction of human plasma with dichloromethane coupled with reversed-phase HPLC and UV detection.
4
For all compounds, we observe significantly more intense red-shifted fluorescence in the solid state compared to that in dichloromethane solutions.
5
Yields of dichloromethane fractions from plants collected in the autumn and spring occurred in a higher proportion than in other seasons.
6
Chloroform was evaporated and the residue was dissolved with dichloromethane which was then transferred for clean-up onto a silica 'Sep-Pak' cartridge.
7
Upon oxidation with antimony pentachloride in dichloromethane, charge transfer transitions between the platinum and ligand are observed for the three complexes.
8
Last year scientist also raised concerns over the level of dichloromethane in the stratosphere, a chemical not covered by the ozone rescue pact.
9
Conclusion: Our findings suggest that exposure to industrial dichloromethane releases may be a risk factor for childhood germ cell tumors, teratomas, and possibly AML.
10
Scientists have already raised concern about the potential ozone impact of man-made chemicals called "very short-lived substances" or VSLS, such as dichloromethane.
11
Although "currently modest, the impact of dichloromethane on ozone has increased markedly in recent years," a team reported in the journal Nature Communications.

The evaluation of the dichloromethane extract, and its major compounds for their anti-inflammatory and anti-oxidant potential was performed in macrophages J774A.1 and C6 astrocytes.
