16. Code groups¶
The IQAASL project used the item codes and descriptions from the Marine Strategy Framework (MSFD) master list [Han13]. Item identification follows the protocols from the MSFD Technical Subgroup on Marine Litter. The master list was developed based on the categories of items used in a series of programs and is one of the most detailed, representing established EU protocols. There are 217 identification codes to classify all objects collected from a survey. The item codes begin with G1 and end with G217.
16.1. Accounting for regional objects¶
There are items identified regularly in Switzerland that do not appear in the master list. To account for this 43 codes were added to the master list under the parent code G124. These codes begin with G900 and end with G999.
Some MSFD codes such as G124 other plastic/polystyrene items, identifiable allows for quantification of unlisted identifiable plastic items. An added item such as G913 pacifier can be quantified independently and linked to the MSFD code G124. This work is done at the server and the data can be analyzed using either form.
Identifiable plastic objects were either attributed to an additional code such as G913, or if no other code described the item then G124 was used. Some codes were included to capture pandemic related items such as:
G901 Mask medical, synthetic (Parent code (G124) other plastic/polystyrene items identifiable)
G902 Mask medical, cloth (Parent code (G145) other textiles)
Codes and parent codes: accounting for regional differences. G902 is linked to G145 by the value in the column parent_code. G937 is linked to G124 by the parent code.

16.1.1. Modification of items by size and material descriptions¶
Several important size and material modifications were made specifically to the fragmented plastic and foamed plastic categories. Other modifications include expansion or narrowing of item descriptions.
G96 sanitary towels, panty liners modified to include plastic tampon applicators.
G211 adhesive bandages modified from unclassified material to plastic.
To best identify and quantify micro plastics for this project 3 codes were modified by size from the master list.
Codes modified to account for objects less than 5mm:
G75 Plastic/polystyrene pieces 0 - 2.5 cm modified to 0.5 cm - 2.5 cm
G78 Plastic pieces 0 - 2.5cm modified to 0.5cm - 2.5cm
G81 Polystyrene pieces 0 - 2.5cm modified to 0.5 cm - 2.5 cm
Various sizes of plastic pieces

16.1.2. Foamed plastics: Gfoams¶
Expanded polystyrene G81, G82, G83 grouped as Gfoam, are light, friable, often white foamed plastics used for packaging or insulation. Foamed plastic items commonly used for take out food G10, sponge foams G73 and denser insulation foams G74 are categorized separately and not included in the expanded polystyrene group.
The foam packaging/insulation/polyurethane G74 was expanded in this study to include extruded polystyrenes (XPS) that are commonly used as insulation and conversely narrowed for G81, G82, and G83 polystyrene pieces to expanded polystyrene (EPS) larger than 0.5cm. These modification were to differentiate insulation foams from packaging foams although both are used for a variety of applications. The material modifications to the foamed plastics is grouped to the parent code for analysis and recorded separately. A detailed inventory of the type and size of foam is provided with each report.
Note
Polystyrene beads less than 5mm, brand name Styrofoam® are grouped with micro plastics (G117) styrofoam < 5mm.

16.1.3. Not applicable or omitted items¶
Of the 217 MSFD codes available 176 of the items were identified in the 2020-2021 surveys. Several items are not applicable to Swiss waters as they pertain to marine aquaculture production:
G207 octopus pots
G163 crab/lobster pots
G215 food waste/galley waste*
All naturally biodegradable food waste as well as feces collection and quantification was omitted from this project.
16.2. Objects grouped by use¶
Individual item codes have been grouped to best describe usage and possible sources. It is acknowledged that some items in a group contribute to a percentage rather than the whole sum. Code grouping is a broad analysis method to evaluate the discarded materials found in water systems by economic sectors or physical properties. Items are also analyzed independently in this report. The grouping is derived from field observations and research to determine possible sources of various pollutants.
wastewater: items released from water treatment plants includes items likely toilet flushed
micro plastics (< 5mm): foams, plastic fragments and pre-production resins
infrastructure: items related to construction and maintenance of all buildings, roads and water/power supplies
food/drink: primarily single use plastic items related to consuming food and drinks outdoors
agriculture: mainly industrial sheeting for: mulch, row covers, greenhouses, soil fumigation and bale wraps includes hard plastics: agricultural fencing, plastic flower pots etc.
tobacco: predominately cigarette filters, includes all smoking related material
recreation: fishing, hunting, boating and beach related objects, excludes food, drink and tobacco
packaging non food/drink: packaging or wrapping material not identifiable as food, drink nor tobacco related
plastic pieces: plastic or foam/plastic composite pieces greater than 0.5 cm
personal items: personal use related; accessories, hygiene and clothing
Unclassified: ungrouped item codes
Material grouping examples
16.2.1. Wastewater treatment¶
Wastewater treatment codes includes toilet flushed plastic items such as cotton swabs and direct use items such as biomass holders.
Note
G98 includes diapers and wipes. Diapers are rarely found in Swiss water systems the quantities should be attributed to personal hygiene wipes.

16.2.2. Micro plastics¶
Micro codes are all micro plastics and foams from the master list items G103-G123. Not all codes have been identified in our data. The objective of this project was to quantify observable litter which tends to be greater than 0.5 cm but the lower limit of natural visible detection when surveying a shore line is around 2 - 5mm. Over the course of a survey, visible micro items are collected with the lager material and composition is generally identifiable. The IQAASL project did not include methods to specifically target items less than 5mm but all visible micro plastics collected during a survey were quantified, weighed and categorized using 20 codes available to classify plastics less than 5mm.

16.2.3. Infrastructure¶
Infrastructure relates to all forms of construction, renovations and maintenance of public and private structures including roads, bridges and ports as well as power and water supplies. Important quanties of construction plastics and especially foamed plastics were identified along all lakes of study. See survey results 2020-2021 All surveys areas
The most common construction plastics are pieces of piping, flexible and rigid hosings and cable protectors as well as associated connectors, fittings and covers. Also common are plastics used in concrete forming such as dowels, anchors and spacers. Some items associated with plastic construction have unique codes such as G93: cable ties or G17: injection gun containers.
Other items in the infrastrucutre group have a more general use case:
G186 Industrial scrap
G194 Metal cables
16.2.3.1. Infrastrucutre: foamed plastics¶
All foamed plastics associated with insulation applications are attributed to the infrastructure group. Extruded foams are relatively dense multi colored foam boards and spray foams greater than 0.5 cm. Expanded polystyrene is included as infrastructure related due to the common use as an exterior insulator for above ground applications. Additional codes were created to quantify size variations of foams, G909 - G912. The modifications were to differentiate construction insulation foams from packaging foams although both are used for a variety of applications. The material modifications to the foamed plastics is grouped to the parent code for analysis and recorded separately. A detailed inventory of the type and size of foam is provided with each report.
Various sizes of foamed plastics; XPS, EPS, and spray foams SPF along Swiss shorelines

16.2.5. Agriculture¶
Several codes were added to identify items pertaining to agriculture such as G937: plastic pheromone baits commonly used in vineyards and G943: plastic fencing associated with seasonal animal pasturing. The specific sheeting code G936: greenhouse films and silage wrap was added for a particular type of product where the agriculture use is identifiable.
Industrial sheeting (G67) is a broad category that includes plastic sheets and films that are flat pieces of plastic formed to a precise thickness for use in specific applications. Products differ in terms of materials, properties, and dimensions [ogsapfpss]. Isolating agricultural plastic sheeting use is difficult as the same plastics are utilized extensively in the packaging and construction sectors. Predominately along Swiss shorelines plastic sheeting and films are extremely weathered and fragmented making definitive use and origin difficult to determine.
Industrial sheeting is attributed to the agriculture group due to continious exposure to physical elements and use in close proximity to rivers, streams and canals. Industrial sheeting is also attributed to agriculture due to the continuously increasing use of plastic materials in agricultural applications commonly referred to as plasticulture. Plasticulture includes irrigation tubing, plastic nursery pots, and an extensive use of sheeting, wraps and films for horticultural, grain crops and dairy sectors [Orz17].

16.2.11. Unclassified items¶
The non grouped codes are predominately items that are ambiguous in origin, rarely identified, or do not pertain to shoreline surveillance of Swiss water systems. Many of the non grouped items have a total value of 0 for all survey data included in this report.
Notable exceptions are G20 and G23 plastic caps/lids unidentified which are found in significant quantities but use and origin are unknown.
Glass or ceramic fragments >2.5cm G208 is also unclassified in this report. Predominately ceramic pieces of unknown use or origin are identified frequently and in relatively high concentrations. The occurrence of ceramic fragments may be related to the sources of material for beach replenishing practices as well as natural transport and deposition processes rather than food and drink or other beach related activities. Identifiable glass drink bottles and pieces are classified as (G200) bottles and includes pieces, they are grouped with food and drink.
