SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Personal protection: protective gloves and particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

TERRESTRIAL FATE: Based on a recommended regression classification scheme(1), an estimated Koc value of 1800 (SRC), determined from a measured water solubility of 5 mg/l(2) and a recommended regression-derived equation(3), indicates that C.I. Fluorescent Brightener will have low mobility in soil(SRC). In one experiment, clean water was percolated through sludge containing fluorescent whitening agents. After 68 days the total amount leached from the original 216 mg C.I. Fluorescent Brightener 260 in 20 kg sludge was only 0.02%(6). As C.I. Fluorescent Brightener 3 is an ionic compound at environmental pHs, volatilization of this compound will not be important from moist soil surfaces(4,SRC). Based on limited data, C.I. Fluorescent Brightener 260 is expected to be resistant to aerobic biodegradation(SRC); C.I. Fluorescent Brightener 260 was not biodegraded in a standard 5 day BOD test(5).

AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 1800(SRC), determined from a measured water solubility(3) and a recommended regression-derived equation(2), indicates that C.I. Fluorescent Brightener 260 may adsorb to suspended solids and sediment in water(SRC). However, due to the ionic nature of C.I. Fluorescent Brightener, the retention of the brightener by ion-exchange processes(4,SRC), particularly on clay surfaces, and adsorption at mineral surfaces such as geothite(5,SRC), may lead to increased adsorption on some sediment and particulate surfaces(SRC). As C.I. Fluorescent Brightener 260 is an ionic compound, volatilization from water surfaces is not expected(4,SRC). According to a classification scheme(6), a BCF range of 1.4 to 28 in carp(3) suggests that bioconcentration in aquatic organisms is low(SRC). Based on limited data, C.I. Fluorescent Brightener 260 is expected to be resistant to aerobic biodegradation in water(SRC); C.I. Fluorescent Brightener 260 was not biodegraded in a standard 5 day BOD test(7). In a river die-away test at which carbon dioxide production was measured in solutions of maximum 1000 ppb over a period of 35 days, no biodegradability was found(7).

ATMOSPHERIC FATE: The ionic state of C.I. Fluorescent Brightener 260 makes this compound essentially non-volatile(1,SRC), therefore this compound will only exist in the particulate phase in the ambient atmosphere. Particulate-phase C.I. Fluorescent Brightener 260 may be physically removed from the air by wet and dry deposition(SRC).

The Koc of C.I. Fluorescent Brightener 260 is estimated as approximately 1800(SRC), using a water solubility of 5 mg/l(1) and a regression-derived equation(2,SRC). According to a classification scheme(3), this estimated Koc value suggests that C.I. Fluorescent Brightener 260 is expected to have low mobility in soil(SRC). Due to the ionic nature of the brightener, the retention of C.I. Fluorescent Brightener 260 by ion-exchange processes(4,SRC), particularly on clay surfaces and adsorption at mineral surfaces such as geothite(5,SRC), may slow down or prevent leaching(SRC). In one experiment, clean water was percolated through sludge containing fluorescent whitening agents. After 68 days the total amount leached from the original 216 mg C.I. Fluorescent Brightener 260 in 20 kg sludge was only 0.02%(6).

Laboratory experiments showed that fluorescent whitening agents used in detergents are not readily biodegradable. Tests which used the oxygen consumption over 5 days as a measure of the ability of fluorescent agents to serve a substrate for bacterial growth gave no evidence of biodegradation; C.I. Fluorescent Brightener 260 had a BOD5 of zero. In a river die-away test at which carbon dioxide production was measured in solutions of maximum 1000 ppb over a period of 35 days, no biodegradability was found(1).

Fluorescent whitening agents are strongly adsorbed to soil. In one experiment, clean water was percolated through sludge containing fluorescent whitening agents. After 68 days the total amount leached from the original 216 mg C.I. Fluorescent Brightener 260 in 20 kg sludge was only 0.02%. The sludge had been exposed to natural weather and non-agricultural conditions(1).

C.I. Fluorescent Brightener 260 is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(1). Fluorescent whitening agents, which includes C.I. Fluorescent Brightener 260, have an UV absorption maximum between 340 to 360 nm in water and transform UV energy almost quantitatively into blue fluorescent light(2).
