# 3 1. Executive Summary

Thiamethoxam is a systemic insecticide registered for use on numerous crops such as grain cereals, vegetables, oilseeds, fruits, turf, soybean, and ornamentals for the control of commercially relevant sucking and piercin g insects that feed on the v ascular tissue of crop plants. The proposed action is to register thiamethoxam as a seed treatment for use on dry bulb onions at the rate of 0.18 lb a.i./acre and peanuts at a rate of 0.08 lb a.i./acre . In addition, this

assessm ent characterizes potential risks associated with i ncrease d rates and/or application of thiamethoxam as a seed treatment rather than a fol iar spray on crops including carrots, leafy vegetables, and brassica (cole) leafy vegetables. Finally, corn is also in cluded in this assessment as it does not appear to have been assessed by EFED at any application rate or method previously

.

A number of risk assessments have been conducted on thiamethoxam. Previous assessments have identified potential risks primarily t o terrestrial and aquatic invertebrates, although potential for risk also exist s for birds and mammals. Because thiamethoxam is systemic and persistent, particular concern for non

- target beneficial arthropods, including pollinators

, has been identified (D P 357206

, May 18, 2009 ). Additionally, potential risks to aquatic invertebrates due to exposure to the degradate CGA

- 322704 (clothianidin) ha ve been identified

. Taxonomic groups for which concern levels were exceeded for the assessed uses are summarized in T able 1

. Use Characterization

The registrant has proposed to register thiamethoxam as seed treatments on dry bulb onions at the rat e of 0.18 lb a.i./acre (Cruiser 70WS) and peanuts at the rate of 0.08 lb a.i./acre (Cruiser 5FS and Cruiser PD)

. Application is assumed to be limited to ground as treated seed must be incorporated to a depth of at least one inch. Table 2 summarizes the pr oposed new uses , which are denoted by a single asterisk

. Table 2 also includes uses on the submitted labels that have been previously registered but do not appear to have been assessed by EFED or not assessed at the current rate and/or application method

. T hese uses included in the quantitative portion of this risk assessment are denoted by a double asterisk

.

# 4 Uses listed in Table 2 that are not denoted by either a single or double asterisk are not included in this assessment . However, these uses may nee d to be re

- evaluated after the current labels are revised to provide crop

- specific application rates.

Cruiser 70WS is a wettable powder that is tank

- mixed with water . It is packaged in water

- soluble bags, which are added, unopened, to the mixing tank . Cruiser 5FS is a water

- based slurry that is diluted with water and applied to the seed using standard slurry seed treatment equipment. Cruiser PD is a wettable powder that was developed for dry application to peanut seed. The Cruiser PD label does not st ate that a seed sticker must be used. Use of a seed sticker would presumably reduce the amount of thiamethoxam that may leave the seed in dust particles during planting

# The California crop profile indicates that, typically, 4

- 5 lb onion seed are planted per acre. The registrant assumes that 3 lb onion seed/acre are planted (406,000 seeds/acre ÷ 136,000 seeds/lb). The estimated rate was obtained as follows: 0.18 lb a.i./acre ÷ 3 lb seed/acre * 5 lb seed/acre = 0.30 lb a.i./acre.



# 2.1. Scope of Assessment

This assessment considers thiamethoxam and one degradate of concern (clot hianidin) for aquatic animals. Clothianidin is of simila r or less toxicity to terrestrial animals compared to thiamethoxam ; therefore, potential risks were not quantified for terrestrial animals resulting from exposure to this degradate

. This assessment follows an abbreviated format because a full assessment was complete d recently (DP357206, May 18, 2009)

, and risk conclusions are similar to previous assessments . Two new studies have been reviewed

, and the results are presented in Section 4 ; how e ver , neither study produced toxicity values that could be used quantitatively in this risk assessment.

2.2 Nature of the Chemical Str essor

Thiamethoxam is very soluble (4100 mg/L) in water. The vapor pressure (4.95 x 10 - 11 

# mm Hg) and Henry's Law Constant (4.65 x 10 - 15 

# atm m 3 

# /mol) indicate that the compound is relatively

non

- volatile under field conditions. The compound does not dissoci ate within the range of pH 2 to 12. All fate data requirements for thiamethoxam are fulfilled except for the bioaccumulation

# 6 fish study (165

- 4) for which a waiver has been requested (U.S. EPA, 2006). However, the n

octanol water partition coefficient (Log K ow 

# =

- 0.13) for thiamethoxam indicates a low potential for bioaccumulation.

The principal routes of dissipation for thiamethoxam are photodegradation in water, alkaline

catalyzed hydrolysis, and leaching. Other probable routes of dissipation are aerobic aquatic metabolism and foliar absorption. Aerobic aquatic metabolism is considered a probable route of dissipation based on the different rates of degradation of thiamethoxam in terrestrial and aquatic environments; thiamethoxam had substantially lower ha lf

- lives (13.8 to16.8 days) in aerobic aquatic environments as compared to aerobic soil environments (112 to 408 days). This apparent difference in the persistence of thiamethoxam in terrestrial and aquatic environments is likely to be due to hydrolysis un der alkaline pH conditions in the aerobic aquatic metabolism study. Additionally, root uptake, leaching, and foliar absorption are expected to be a probable route of dissipation because thiamethoxam is a systemic insecticide with an extremely low partitio ning coefficient.

Additional environmental fate data can be found in the earlier assessment ( DP357206, May 18, 2009).

# 7 3

. Exposure Summary

3 .1. Terrestrial Exposures

T

- REX v1.4.1 was used to estimate potential exposures to birds and mammals. Estimate d concentrations of thiamethoxam to which birds and mammals could be exposed via consumption of treated seed are in Table 3 . Additionally, Table 3 includes an estimate of available active ingredient per square foot to which birds and mammals could be expos ed. EECs used to calculate risk quotients for birds and mammals that may consume treated seeds are based on the concentration of thiamethoxam on treated seeds. These EECs are limited by the fact that the labels indicate the amount of a.i. to be applied (in mg) per seed

. There is a large range of seed sizes as well as differences in optimal seeding rates ; therefore, the concentration of thiamethoxam on seeds may vary depending on the size of the seed

, and the application rate (lb a.i/ a cre) may vary considera bly depending on the seeding rate used. Therefore, there are uncertainties as to the actual dose s that would be available to terrestrial animal s via consumption of treated seed s

. Due to these uncertainties, EECs could over

- or under

- estimate exposures and risks. However, inputs resulting in high

- end exposures were used for this assessment. For example, if a label specifies the mg a.i. to be applied per seed and the maximum lb a.i. to be applied per acre, the number of seeds planted per acre would remain con stant. A minimum seeding rate (in terms of lb seed to be planted per acre) would increase exposure because only the size (weight) of the seed varies. A greater number of small seeds would have to be consumed to satisfy dietary requirements of birds and mam mals in comparison to large seeds, thus increasin g the amount of a.i. consumed ( e.g., 5 large seeds * 0.29 mg a.i./seed = 1.45 mg a.i. consumed vs. 10 small seeds * 0.29 mg a.i./seed = 2.90 mg a.i. consumed). If labels were to specify the application rate in terms of lb a.i. to be applied to 100 lb seed, maximum seeding rates (lb seed to be planted per acre) would provide maximum exposures ( e.g., 2 lb a.i./100 lb seed planted at a rate of 100 lb seed/acre = 2 lb a.i./acre vs. 2 lb a.i./100 lb seed planted a t a rate of 80 lb seed/acre = 1.6 lb a.i./acre).

# EECs produced by T

- REX were multiplied by 0.01 to account for burying of seeds , which is required on the label

. T

- REX input determined as follows (in some cases, minimum seeding rates (lb seed/acre) were chosen to maximize potential exposure as labe ls specified application in terms of mg a.i./seed; an animal would have to eat more small seeds than large seeds to satisfy dietary requirements ) :

- The California crop profile indicates that, typically, 4

- 5 lb onion seed are planted per acre ( http://www.ipmcenters.org/CropProfiles/docs/caonions.pdf ) . The registrant assumes that 3 lb onion seed/acre are planted (406,000 seeds/acre ÷ 136,000 seeds/lb). The estimated rate was obtained as follows: 0.18 lb a.i./acre ÷ 3 lb seed/acre * 5 lb seed/acre = 0.30 lb a.i./acre. This higher rate was also modeled because it is not certain whether the 406,000 seeds/acre will be included on the seed bag label.

- The Alternative Field Crops Manual indica tes a typical peanut seeding rate of 90,000 seeds/acre in Minnesota and Wisconsin ( http://www.hort.purdue.edu/NEWCROP/AFCM/peanut.html ). Using the registrant provided seed weight maximum of 1397 seeds/lb, a seeding rate of 64 lb seed/acre was calculated for input into T

- REX.

- The California crop profile indicated a seeding rate of 6 lb seed/acre for leafy vegetables ( http://www.ipmcenters.org/CropProfiles/docs/calettuce

- iceberg.pdf )

.

- Texas A&M indicated a seeding rate of 1.5 lb seed/acre for c ole crop s (broccoli) 1.5 lb seed/acre ( http://aggie

horticulture.tamu.edu/extension/vegetable/cropguides/broccoli.html ).

- The Georgia crop profile indicated a seeding rate of 2 lb seed/acre for c arrots ( http://www.ipmcenters.org/CropProfiles/docs/GAcarrots.pdf ).

- The corn seeding rate of 5.45 lb seed/acre was calculated using the Alternative Field Crops Manual and the North Central Region crop profile ( http://www.hort.purdue.edu/newcrop/afcm/popcorn.html

# Two additional studies have been submitted and reviewe d since completion of the most rece nt previous assessment. A honey bee foliar residue toxicity study , which was classified as supplemental, has been reviewed ( OPPTS 850.3030, MRID 447275

- 01). Residues were not quantified in foliage from any treatment level

, and control foliage was only aged for 24 hours. M ortality at the highest application rate ranged from 80 to 89% between 24

- and 72

- hour residue age periods, never approaching the control mortality (1%); therefore, residue times to produce significant mor tality useful for risk assessment ( i.e., RT 25 

# values) could not be extrapolated from these data. Qualitatively, these data show that residues of CGA

- 293343 (thiamethoxam) from foliage exposed to 0.004 lb a.i./acre did not result in significant mortality (< 1 to 2%) of bees exposed to residues 24 to 72 hours after application, while significant mortality (89 to 80%) occurred for bees exposed to foliar residues applied at 0.088 lb a.i./acre. Although the decrease from 89 to 80% was not statistically significan t, these data follow a suggestive pattern of decreasing toxicity with increasing residue age.

A red swamp crayfish ( Procambarus clarkii ) study (OPPTS 850.1010, MRID 475581

- 06) has also been reviewed since the most recent previous assessment was conducted

. Based on death and immobilization, the EC 50 

# was 2.3 mg a.i. /L

. The lack of a linear dose

- dependent response in this study precluded a reliable statistical estimation of a 96

- hour LC 50 

# with narrow confidence

# 15 limits, but there were clear effects on mortali ty, ranging from 20

- 50% between the 1.3 and 11 mg a.i./L treatment levels; there was 50% mortality at the 2.6 mg a.i./L level. T he visually determined LC 50 

# was 2.3

- 2.6 mg a.i./L, categorizing thiamethoxam as moderately toxic to red swamp crayfish on an acu te toxicity basis. Altho ugh the LC 50 

# approximates the EC 50 

# , the EC 50 

# is a more appropriate estimate of toxicity because of the lack of a discernible difference between the immobilization and death endpoints. The NOAEC was 0.65 mg a.i./L. The study is class ified as supplemental as red swam p crayfish is not a test species indicated for use in the OPPTS 850.1010 guideline. However, the data produced are scientifically sound and provide valuable information for certain use patterns ( i.e., rice).

4.2. Toxicity Data for the Degradate CGA

A summary of the most sensitive definitive toxicity data for CGA

- 322704 (clothianidin) used to calculate RQs is in Table 9

. Terrestrial animal toxicity data are not inclu ded because clothianidin has demonst rated similar or less toxicity in terrestrial organisms , including in honey bees, as compared to thiamethoxam

. Additional information, including qualitative

# 4.3. Incidents

EFED maintains an incident database system called the Ecological Incident Information System (EIIS) to track and evaluate accidental kills associated with pesticide use. Based on the information contained in the incident r eport, the likelihood of a particular pesticide causing the incident is classified as highly probable, probable, possible, or unlike ly. If there are incidents, the information will be reviewed and considered in conjunction with the degree to which the LOCs were exceeded, information on sales, local use practices, and monitored levels in the

# 16 environment to determine whether the predicted effect based on labeled use of the product is likely to occur or not.

A search of the EIIS database on May 17, 2010 did n ot identify any adverse ecological incidents involving thiamethoxam. Although incident reporting is required under FIFRA Section 6(a)(2), the absence of reports in EIIS does not indicate that the chemical has no effects on wildlife; rather, it is possible that incidents have gone unreported. A search of the EIIS database on May 15, 2009 for incidents involving other neonicotinoids, including clothianidin, imidacloprid, and dinotefuran, identified several incidents. These incidents involved large numbers of bees as well as birds, plants, crayfish, and fish and are currently under review.

Several incidents involving bee kills with other neonicotinoid insecticides in Europe have been reported. For example, a bee kill incident in Germany in May 2008 was likely caused by use of clothianidin as a seed treatment for corn 1



# 5

. Ecological Risks Summary . A seed sticker was not used for the dust treatment, and seeds were planted using upward rather than downward venting equipment, which caused clothianidin dust particles to drift. In addition, h e avy rain caused the corn seed to be planted later than normal when neighboring canola fields were already in bloom

. Similar incidents have occurred in France, Italy, and Slovenia

, causing the need for regulatory action

. A thorough review of all incidents i s currently underway.

5. 1. Potential Risks of Thiamethoxam Exposure to Terrestrial Organisms

This assessment assumes that birds and mammals consume 100% of their diet as treated seeds, and 1% of seed s are available to be cons umed as labels specify incorporation of treated seed to a depth of at least one inch.

5.1.1. Birds

Thiamethoxam is classified as practically n on

- toxic to birds on a dietary basis and slightly toxic on an acute oral dos e basis. R isk quotients were not calculat ed to estimate risks to birds on a dietary basis because no lethal effects were observed at the limit concentration for avian dietary toxicity studies. Dose

- based acute and chronic RQs for birds are shown in Table 10

.

For small birds, all three acute LO Cs were exceeded for birds consuming treated dry bulb onion, brassica (cole) leafy vegetable, and carrot seed using method 1 (mg a.i./kg

- bw/day/LD 50 

# ) . The acute restricted use LOC and acute listed species LOC were exceeded for small birds consuming treated corn and leafy vegetable seed s using method 1 (mg a.i./kg

- bw/day/LD 50 

# ). Using method 2 (mg a.i./ft 2 

# /(LD 50 

# *bw), none of the RQs exceeded any of the LOCs

. C hronic LOC exceedances were observed for corn, dry bulb onions, leafy vegetables, brassica (cole) lea fy vegetables, and

carrots . RQs ranged from 0.04 to 4.89. The peanut seed treatment did not produce chronic LOC exceedances. Chronic effects observed at the LOAEC for birds included weight loss in parental mal es for mallards (LOAEC = 900 mg/kg

- diet ) and r educed egg size for bobwhite quails (LOAEC > 900 mg/kg

- diet ).

# 17 5.1.2. Mammals

Thiamethoxam is classified as slightly toxic to mammals on an acute oral basis . N o ne of the acute RQs exceeded concern levels ( Table 1 0 )

. The chronic LOC i s exceeded for small mammals consuming treated corn, dry bulb onion, leafy vegetable, brassica (cole) leafy vegetables, and carrot seed. RQs ranged from 0.06 to 7.33. The peanut seed treatment did not produce chronic LOC exceedances. Chronic effects observed at the LOAEL (30 mg/kg

- bw /day) for mammals included increased incidence and severity of tubular atrophy in the testes of male

rats.

# 5.1.3. Terrestrial Plants

Data were not submitted to assess the toxicity of thiamethoxam to terrestrial plants. Therefore,

r isks to t errestrial and semi

- aquatic plants are presumed

.

5.1.4. Terre strial Invertebrates

Currently, EFED does not quantify potential risks of pesticides to non

- listed terrestrial non

- target arthropods . However, based on the data submitted on honey bee toxicity, thiamethoxam is highly toxic to honey bees ( LD 50 

# = 0.024 and 0.005 μg /bee on an acute contact and oral exposure basis, respectively). It is possible that terrestrial invertebrates, especially pollinators such as bees, would be exposed to thiamethoxam, as it is a systemic , persistent insecticide . U ncertainties remain regarding the effects to non

- target arthropod s through exposure to translocated residues (the parent thiamethoxam and the degradate clothianidin) in nectar and pollen. While the degree to which thiamethoxam is metabolized to clothianidin within the plant is unknown and ma y vary

# 18 by crop, clothianidin has similar toxicity to thiamethoxam , which is demonstrated by acute contact and oral honey bee data. Pollinator field study data have been requested to evaluate potential effects through these possible routes of exposure ; some data have been received and are currently under review

. In addition, residue data in the open literature has recently been identified as well as data produced for the California Department of Pesticide Regulation. These data will be revie wed and included in future assessments as appropriate.

Due to the incidents associated with other neonicotinoids in Europe (see Section 4.3 ) and

c onsidering the a vailable data

, potential for risks to pollinators and other non

- target beneficial arthropods resulting from the proposed and existing applications of thiamethoxam exists

. These risks were not quantified. A practice to m itigate risks to non

- target arthropods, which may provide commercially important pollination and other ecological services, inclu de s, but is not limited to

, establishing and maintaining alternative untreated habitat and forage in areas surrounding agricultural fields 2



# A summary of risk quotients based on acute exposure of freshwater midge and estuarine/marine mysid to thiamethoxam is presented in Table 1 1

, below

. With risk quotients ranging from 0.01

– 0.33 for freshwater midge, the a cute listed species and restricted use LOCs a re exceeded for freshwater invertebrates for most of the scenarios

. Only four scenarios assessed (two for dry bulb onions

, one for peanuts , and one for corn ) did not produce RQs that exceeded LOCs. Every

as sessed use exceeded the restricted use and listed species LOC except for peanuts , which did not result in any LOC exceedances

. R Q s for estuarine/marine spe cies were <0.01 ; acute risks to .

5 .2. Potential Risks of Thiamethoxam Exposure to Aquatic Organisms

5.2.1. Fish

A definitive LC 50 

# was not establi shed for thiamethoxam for both freshwater and estuarine/marine fish. As a result, acute risk quotients were not calculated for fish. However, a comparison of the established NOAEC values of 100,000 μg/L for rainbow trout, 114,000 μg/L for bluegill sunfish, and 111,000 μg/L for sheepshead minnow from acute exposure studies with the estimated peak surface water concentrations of thiamethoxam, which ranged from 0.45 to 11.47 μg/L , suggest that estimated peak exposure concentrations are well below the concentra tions shown to result in

no adverse effects to both freshwater and estuarine/marine fish. Therefore, potential risks do not trigger concerns at this time for either freshwater or estuarine/marine fish on the acute exposure basis.

Although no chronic eff ects on reproduction were noted, a comparison of the highest dose tested in the study (20,000 μg/L ) for freshwater rainbow trout with the 60

- day average EECs ( 0.27 to 7.58 μg/L ) indicated that exposure estimates are well below concern levels for potential chronic risks to freshwater fish. Although chronic data were not submitted for estuarine/marine fish, chronic risks would similarly fall below concern levels as acute freshwater and estuarine/marine fish data do not suggest a difference in sensitivity acro ss media.

# Based on t he acute to chronic ratio ( ACR )

- derived midge NOAEC (NOAEC <16.51 μg/L , see Section 4.1.2 of the previous assessment ; DP357 206 , May 18, 2009 )

, it is possible for chronic LOCs to be exceeded because chronic EECs ranged from 0.39 to 9.85 μg/L . C hronic risk to freshwater invertebrates cannot be ruled out until acceptable chronic mid ge data (satisfied by the 850.1 735 guideline) providing a definitive NOAEC is submitted to the Agency. Since the ACR

derived midge NOAEC is non

- definitive (<16.51 μg/L ), chronic risks to freshwater invertebrates

were assumed to exceed LOCs for all uses. Additionally, either the chronic midge data or a chronic estuarine/marine study is needed to evaluate risks to estuarine/marine invertebrates. In the absence of this data, chronic risks to estuarine/marine invertebrates were assumed for listed species.

5.2.3. Aquatic Plant s

Potential risks to aquatic plants from the proposed new uses of thiamethoxam were evaluated using the toxicity data for a vascular plant ( Lemna gibba ) and a non

- vascular plant ( Pseudokirchneriella subcapitata ) . Toxicity values for these two aquatic plan ts were non

definitive (> than the highest concentration tested); therefore, risks for the above species were

# 21 ascertained based on the comparisons of estimated peak thiamethoxam concentrations in surface water and the non

- definitive toxicity values. T he mo st conservative peak EEC (11.47 μg/L for treated leafy vegetable seed) is more than three orders of magnitude lower than the non

definitive toxicity values for vascular (EC 50 

# >90,000 μg/L ) and non

- vascular (EC 50 

# >97,000 μg/L ) plants ; therefore , risks to aq uatic plants are presumably less than concern levels.

5.3. Potential Risks of Major Degradate CGA

- 322704 (Clothianidin) Exposure to Aquatic Organisms

. Data Gaps and Uncertainties

1. Whole Sediment Acute Toxicity Test for Freshwater Invertebrates (850.1735): This 28

- day study measures survival, growth, and emergence of Chironomus riparius that has been exposed to pesticide

- spik ed sediment and overlying water

. EFED recommends that a request be made for this acute sediment toxicity test , which also measures chronic effects, because thiamethoxam is very highly toxic to midge and is persistent in the environment. The previously subm itted study on midge (MRID 447149

- 18) larvae exposed to thiamethoxam

spiked water solution and is 48 hours in duration. Therefore, chronic risks to sediment

- dwelling midge could not be comprehensively assessed using this study. Prior to initiation of this study, a protocol should be submitted to EFED for approval.

2. Field Test for Pollinators (850.3040) 3 

# Because thiamethoxam is highly toxic to honey bees on an acute exposure basis and is a persistent, mobile, and systemic insecticide, pollinators have a high potential of being exposed to and affected by residues of thiamethoxam and its degradation products (clothianidin) in pollen and nectar of plants. EFED recommends that the registrant conduct field studies at maximum proposed la bel rates using crop s t hat are attractive to bees ( e.g., pears or apples) for seed treatment, foliar, and soil applications. These three studies should be conducted in consultation with EFED and should examine the e xposure and effects to adults and brood. The studies should :

# EFED acknowledges recent receipt of a pollinator field study (MRID 480533

- 01). This study is currently under review to determine if it satisfies data requirements. In addition, the California Department of Pesticide Regulation has requested residue monitor ing data. This data, along with relevant open literature, may be used by EFED as appropriate.

# 23 meas ure the amount of thiamethoxam translocated to the nectar and pollen of the target crop and rotational crops and potential adverse effects, including sublethal effects.

3 . Terrestrial Plant Toxicity, Tier I (seedling emergence) (850.4100): Testing of a ty pical end

- use product (TE P) is required for all pesticides having outdoor uses at the proposed maximum application rate. Because thiamethoxam is an insecticide, Tier II studies are not required unless Tier I studies indicate a ≥ 25% effect to various grow th parameters relative to the control. Currently, the lack of these data results in a presumption of indirect effect s to all listed species based on potential habitat modification.

4 . Terrestrial Plant Toxicity, Tier I (vegetative vigor) (850.4150): Test i ng of a TEP is required for all pesticides having outdoor uses at the proposed maximum application rate. Because thiamethoxam is an insecticide, Tier II studies are not required unless Tier I studies indicate a ≥ 25% effect to various growth parameters relative to the control. Currently, the lack of these data results in a presumption of indirect effect s to all listed species based on potential habitat modification

.

5 . Avian Acute Oral Toxicity Test (850.2100): Data are required for one passerine species and either one waterfow l species or one upland game bird species for terrestrial, aquatic, forestry, and residential outdoor uses. The current method of calculating a weight

- adjusted LD 50 

# using bobwhite quail or mallard duck data may over

- or under

- estimate risks to passerines because these birds may metabolize the chemical differently. Because the 850.2100 guideline has not yet been finalized, protocols for the study of passerine species should be submitted to EPA for approval prior to study initiation.

Additionally, the follo wing uncertainties were identified for this risk assessment:

**•** Studies are not available to document the toxic effects of thiamethoxam on chronic exposure basis to both estuarine/marine fish and invertebrates. However, the acute studies for both freshwater fish and estuarine/marine fish do not suggest a great difference in toxicity across media; effects are expected to be similar for both freshwater and estuarine/marine fish. Currently, risks are assumed to estuarine/marine invertebrates on a chronic basis; if a definitive chronic freshwater midge study (850.1735; see data gap #1) is received, the acute

- to

- chronic ratio method can also be used to extrapolate risks to estuarine/marine invertebrates as follows: Chronic toxicity mysid shrimp 

# = Acute toxicity mysid shrimp 

# x Chronic toxicity midge 

# / Acute toxicity midge



# . However, the acute

- to

- chron ic ratio adds uncertainty to the risk estimation because the actual toxicity value and the resulting risk quotients may be over

- or under

- estimated.

**•** This risk assessment only considered the most sensitive of the species evaluated in the registrant

- submit ted studies. The position of the tested species relative to the distribution of all species’ sensitivities to thiamethoxam is unknown. Extrapolating the risk conclusions from the most sensitive tested species to non

- tested species may either underestimate or overestimate the potential risks to those species. T he acute toxicity of thiamethoxam to midge (EC 50 

# = 35 μg/L ) and water flea (EC 50 

# >106,000 μg/L ) highlights this point.

# 24 7. Listed Species

This assessment identified potential direct effects to terrest rial and aquatic invertebrates, birds (surrogate for reptiles and terrestrial amphibians), and mammals, Also, potential risks to listed terrestrial plants were assumed to exceed concern levels due to the absence of toxicity data for terrestrial plants. LO C exceedances for listed species are summarized in Table 1 4

# The Agency’s Level of Concern was exceeded for freshwater invertebrates ( a cute), birds (acute and chronic ), and mammals (chronic); risks to terrestrial plants and chronic risks to all aquatic invertebrates were assumed due to the absence of data, and there is potential for risks to terrestrial invertebrates even though a method for risk quantification is not in practice.

# Indirect effects to a listed species occur when its prey base is reduced or habitat is modified. Indirect effects to all taxa are assumed due to lack of terrestrial plant data.
