"…surprisingly, solar energy can be trapped and stored for long periods in salt water - in a structure known as a solar pond - and this energy can be used to generate electricity via a methylene chloride-powered turbine. This approach has potential to supply power to remote rural areas…"

Novel applications have been reported for chloroform and trichloroethylene molecules in development of an interesting new area of IT: quantum computers. These perform calculations using atoms instead of the computer chips used in conventional computers…"  

"…Enough chlorinated solvent perchloroethylene (PER) to clean 120 million garments in a modern machine helped an American chemist become one of three Physics Nobel Prize winners in 2002. Almost 400,000 litres of PER, which is widely used by dry cleaners, was utilised by Raymond Davis Jr. to conduct a radiochemical experiment in a tank installed down a South Dakota gold mine.

The tank was placed 1,500 metres below the earth's surface to isolate it from cosmic rays that could interfere with detection and measurement of solar neutrinos.

The Davis experiment ran almost continuously for 24 years (1970-94) during which it is calculated 2,200 argon atoms were produced in the tank, of which 776 were estimated to be produced by solar neutrinos…"

Montreal Protocol Meeting - ECSA & HSIA side event

November 2017

DCM & the ozone layer
24 November 2017 – 13hrs – Montréal

During this side event, we will provide you with scientific facts and figures on the worldwide production, emissions of the VSLS Dichloromethane (DCM) and its negligible contribution to ozone depletion.
We will consider the following criteria: global production by industry and emissions, global natural production, behavior and effect on the atmosphere, regulatory overview for DCM.

 

IOELVs for DCM, CTC and PER published

February 2017

Indicative Occupational Exposure Limit Values (IOELVs) for DCM, CTC and PER have been published by the EU Commission (cf. DIRECTIVE (EU) 2017/164 of 31.1.2017), which are in line with the REACH DNEL(inhalation) for workers. 
These IOELVs have to be considered by member states for setting national exposure limits (OELs), which they have to accomplish by 21. August 2018. Only national OELs are legally binding for occupational safety, whereas the IOELVs have to be considered by users in case no OELs is set, yet.  The relevant OELs are provided with the SDS of the solvents suppliers (cf. chapter 8.1). 

 

IARC monograph on DCM

January 2017

DCM has been re-classified by IARC (IARC website) from Group 2B (Possibly carcinogenic to humans) to the next higher Group 2A (Probably carcinogenic to humans). This reclassification from 2014 has been published recently (Dichloromethane).In the opinion of ECSA the reclassification is not scientifically justified. IARC Monograph classifications are also questioned by other associations such as the American Chemical Council (ACC). However the IARC classification is of no regulatory relevance in EU as European legislation is triggered by classification according to the CLP (GHS) regulation (EC 1272/2008).  

 

New Study on DCM

October 2016

Together with HSIA, ECSA supported a study to clarify the mode of action of cancer formation for methylene chloride (DCM). A publication is expected soon in a peer reviewed scientific journal. The outcome of the study shows that below a threshold there is no risk on cancer formation related to DCM.
