Legal and Economic Chemical Data (thermo.law)¶
- thermo.law.economic_status(CASRN, method=None, get_methods=False)[source]¶
Look up the economic status of a chemical.
This API is considered experimental, and is expected to be removed in a future release in favor of a more complete object-oriented interface.
>>> economic_status(CASRN='98-00-0') ["US public: {'Manufactured': 0.0, 'Imported': 10272.711, 'Exported': 184.127}", '10,000 - 100,000 tonnes per annum', 'OECD HPV Chemicals']
>>> economic_status(CASRN='13775-50-3') # SODIUM SESQUISULPHATE [] >>> economic_status(CASRN='98-00-0', method='OECD high production volume chemicals') 'OECD HPV Chemicals' >>> economic_status(CASRN='98-01-1', method='European Chemicals Agency Total Tonnage Bands') ['10,000 - 100,000 tonnes per annum']
- thermo.law.legal_status(CASRN, method=None, get_methods=False, CASi=None)[source]¶
Looks up the legal status of a chemical according to either a specifc method or with all methods.
Returns either the status as a string for a specified method, or the status of the chemical in all available data sources, in the format {source: status}.
- Parameters
- CASRN
str
CASRN [-]
- CASRN
- Returns
- Other Parameters
- method
str
,optional
A string for the method name to use, as defined by constants in legal_status_methods
- get_methodsbool,
optional
If True, function will determine which methods can be used to obtain the legal status for the desired chemical, and will return methods instead of the status
- CASi
int
,optional
CASRN as an integer, used internally [-]
- method
Notes
Supported methods are:
DSL: Canada Domestic Substance List, [1]. As extracted on Feb 11, 2015 from a html list. This list is updated continuously, so this version will always be somewhat old. Strictly speaking, there are multiple lists but they are all bundled together here. A chemical may be ‘Listed’, or be on the ‘Non-Domestic Substances List (NDSL)’, or be on the list of substances with ‘Significant New Activity (SNAc)’, or be on the DSL but with a ‘Ministerial Condition pertaining to this substance’, or have been removed from the DSL, or have had a Ministerial prohibition for the substance.
TSCA: USA EPA Toxic Substances Control Act Chemical Inventory, [2]. This list is as extracted on 2016-01. It is believed this list is updated on a periodic basis (> 6 month). A chemical may simply be ‘Listed’, or may have certain flags attached to it. All these flags are described in the dict TSCA_flags.
EINECS: European INventory of Existing Commercial chemical Substances, [3]. As extracted from a spreadsheet dynamically generated at [1]. This list was obtained March 2015; a more recent revision already exists.
NLP: No Longer Polymers, a list of chemicals with special regulatory exemptions in EINECS. Also described at [3].
SPIN: Substances Prepared in Nordic Countries. Also a boolean data type. Retrieved 2015-03 from [4].
Other methods which could be added are:
Australia: AICS Australian Inventory of Chemical Substances
China: Inventory of Existing Chemical Substances Produced or Imported in China (IECSC)
Europe: REACH List of Registered Substances
India: List of Hazardous Chemicals
Japan: ENCS: Inventory of existing and new chemical substances
Korea: Existing Chemicals Inventory (KECI)
Mexico: INSQ National Inventory of Chemical Substances in Mexico
New Zealand: Inventory of Chemicals (NZIoC)
Philippines: PICCS Philippines Inventory of Chemicals and Chemical Substances
