SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Primary eye irritation - slight iritis and conjunctival irritation; Primary dermal irritation - slight erythema; Dermal Sensitization - not a sensitizer.

Gossyplure is the sex pheromone of pink bollworm, Pectinophora gossypiella(1).

Gossyplure's isolation may result in its release to the environment through various waste streams; its use as an insect attractant(1) will result in its direct release to the environment(SRC). Specifically, the compound is employed as a mating disruptant of pink bollworm in cotton(2).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2.5X10+4(SRC), determined from a structure estimation method(2), indicates that gossyplure is expected to be immobile in soil(SRC). Volatilization of gossyplure from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure of 8.25X10-5 mm Hg(3) and water solubility of 0.2 mg/L(3). Gossyplure is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 8.2X10-5 mm Hg(3). Biodegradation data were not available(SRC, 2018).|TERRESTRIAL FATE: Gossyplure soil persistence was analyzed using 10 mg test compound added to flooded Lufkin fine sandy loam exposed to continuous fluorescent light in an environmental chamber held at 32 °C for up to 14 days(1). Only traces remained at the end of the test period; a half-life of approximately 24 hours was calculated with loss being attributed to volatilization(1). A half-life in soil of 1 day has also been reported(2).|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2.5X10+4(SRC), determined from a structure estimation method(2), indicates that gossyplure is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 1.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure of 8.25X10-5 mm Hg(4) and water solubility of 0.2 mg/L(4). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 15 hours and 10 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 19 months if adsorption is considered(5). According to a classification scheme(6), an estimated BCF of 2400(SRC), from an estimated log Kow of 7.31(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is very high, provided the compound is not metabolized by the organism(SRC). Hydrolysis is not expected to be an important environmental fate process based on a base-catalyzed second-order hydrolysis half-lives of 9 years and 180 days at pH values of 7 and 8, respectively(2). Biodegradation data were not available(SRC, 2018).|AQUATIC FATE: Gossyplure soil persistence was analyzed using 10 mg test compound in aqueous solution exposed to continuous fluorescent light in an environmental chamber held at 32 °C for up to 14 days(1). Less than 10% remained at the end of the test period; a half-life of approximately 14 days was calculated with loss being attributed to volatilization(1). A half-life in water of 7 days has also been reported(2).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), gossyplure, which has a vapor pressure of 8.25X10-5 mm Hg at 25 °C(2), is expected to exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase gossyplure is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air by the cis-isomer is estimated to be 3 hours(SRC), calculated from its rate constant of 1.3X10-10 cu cm/molecule-sec at 25 °C (1.4X10-10 cu cm/molecule-sec at 25 °C, half-life of about 1 hour for the trans-isomer)(SRC) that was derived using a structure estimation method(3). Particulate-phase gossyplure may be removed from the air by wet or dry deposition(SRC). Gossyplure directly exposed to sunlight for up to 24 hours did not photodegrade(4) and, therefore, it is not expected to be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of cis-gossyplure with photochemically-produced hydroxyl radicals has been estimated as 1.3X10-10 cu cm/molecule-sec at 25 °C (1.4X10-10 cu cm/molecule-sec at 25 °C for the trans-isomer)(SRC) using a structure estimation method(1). These values correspond to an atmospheric half-life of about three hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of cis-gossyplure with ozone has been estimated as 2.6X10-16 cu cm/molecule-sec at 25 °C (4.0X10-16 cu cm/molecule-sec at 25 °C for the trans-isomer)(SRC) that was derived using a structure estimation method(1). These values correspond to an atmospheric half-life of about one hour at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). A base-catalyzed second-order hydrolysis rate constant of 4.6X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(2); this corresponds to half-lives of 9 years and 175 days at pH values of 7 and 8, respectively(3). Gossyplure applied to slides and directly exposed to sunlight for up to 24 hours did not photodegrade, with loss being attributed to volatilization(4); therefore, gossyplure is not expected to be susceptible to direct photolysis by sunlight(SRC).

An estimated BCF of 2400 was calculated in fish for gossyplure(SRC), using an estimated log Kow of 7.31(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of gossyplure can be estimated to be 2.5X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that gossyplure is expected to be immobile in soil. In a soil column study of fine sandy loam, gossyplure, applied at 50 mg gossyplure, was not detected in the eluates following washing with 5 liters of distilled water(3).

The Henry's Law constant for gossyplure is estimated as 1.5X10-4 atm-cu m/mole(SRC), derived from its vapor pressure of 8.25X10-5 mm Hg(1) and water solubility of 0.2 mg/L(1). This Henry's Law constant indicates that gossyplure is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 15 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 10 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is 19 months when adsorption is considered(3). Gossyplure's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Gossyplure is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Occupational exposure to gossyplure may occur through inhalation and dermal contact with this compound at workplaces where gossyplure is produced or used. Use data indicate that the general public is not likely to be exposed to gossyplure. (SRC)
