AEROBIC: An addition of fly ash up to 0.5% in a sandy clay loam results in increased degradation of atrazine by 13.3% on the average; the same amount of fly ash in clay soil increases atrazine degradation by 9.0%(1). The half-life of atrazine at 25 deg C in wet (and dry) Colorado loam soil, New York sandy loam soil, and Mississippi silt loam was determined to be 30 (90), 28 (55), and 35 (78) days respectively(2). The percent atrazine remaining from rhizosphere and edaphosphere (non-vegetated) soil samples collected at an agrochemicals dealership in Iowa was determined to be approximately 55% in the rhizosphere and 75% in the edaphosphere, suggesting that the microbial activity of Kochia sp in the rhizosphere soil increased atrazine degradation(3). Atrazine was found to exhibit a half-life of about 30 days in soil samples collected from the top surface (10 cm) from the Ebro delta, Tarragona, Spain between 1989 and 1991; deethyl atrazine was the major degradate formed, with deisopropylatrazine detected in one sample(4). Degradation studies of atrazine in subsoils from an Atlantic coastal plain watershed revealed 13.3 to 25.0% carbon dioxide evolution from sandy loam soils, indicating that atrazine was not appreciably mineralized in the soils(5). Atrazine had half-lives in the range of 20-360 days, observed in laboratory studies conducted with loamy soil from a corn field in Bologna, Italy(6). The shortest half-lives were observed for soils inoculated at temperatures of 35 deg C, while the longest half-lives observed occurred at 5 deg C(6). Experiments with s-triazine-adapted Colorado soil (35.2% sand, 28% silt, 36.8% clay, 19 g C/kg organic matter and pH 7.9) had atrazine degradation half-lives of 2.0 to 28.2 days(7). Experiments with s-triazine-adapted Mississippi soil (15.8% sand, 47.2% silt, 36.7% clay, 13 g C/Kg organic matter and pH 6.67) had atrazine degradation half-lives of 0.8 to 5.6 days(7).

The BCF of atrazine in various aquatic organisms is: bluegill sunfish, <2.1-12; whitefish fry, 4-5; brook trout, <0.27; fathead minnows, 0.9-2.1; mottled sculpin, 2.0; golden ide, 1.0; black bullhead, 0.3; fish, 11; annelids, 4; freshwater snail, 4-5; mayfly nymphs, 480; snails, 7.5; daphnids, 2.2-4.4; algae, 76; soil fungi and bacteria, 87-132(1). Experimental log BCF values of 2.0, 1.0, 0.9, 0.5 and 0.3 have been reported for atrazine in Cottus bairdi (mottled sculpin)(2), Leuciscus idus melanotos (golden ide)(3), Pimephales promelas (fathead minnow)(4), Coregonus fera (whitefish)(5) and Ictaluras melas (catfish)(6), respectively. In vivo sampling of juvenile rainbow trout (Oncorhynchus mykiss) resulted in BCF of 0.49 in muscle and 4.94 in adipose tissue(7). According to a classification scheme(8), these BCF values suggest bioconcentration in aquatic organisms is low to moderate(SRC). The BCF of atrazine in Daphnia magna ranged from 2.4 to 3.0 in natural European waters (13 rivers, 1 humic lake)(9).

The Koc of atrazine in loamy soil, calcareous clay, and high clay was determined to be 109.9, 80.0, and 88.9, respectively(1). The Koc values for atrazine in four Hawaii soils ranged from 54 to 150 mL/g(2). The Koc for a Zimmerman fine sand, a Verndale sandy loam, and a Waukegan silt loam, each with 9.6% water content, was determined to be 1164, 775, and 936, respectively(3). The Koc range for atrazine in salt marsh sediment was 64 to 546, indicating that atrazine undergoes negligible adsorption onto suspended sediments(4). The Koc of atrazine in Norfolk soil, Rion soil, Cape Fear soil, and Webster soil was determined to be 150-200, 84, 202, and 166, respectively(5). Atrazine had a reported mean Koc of 126.9 (range of 26 to 821) in 101 allophanic and non-allophanic surface soil samples collected throughout New Zealand(6). Koc values for three regions of Argentina were reported as 77 to 161(7). Koc values of two soils from Reunion Island, France were reported as 97 and 117(8). Atrazine had measured Koc values of 88 in vegetated filter strip soil (37.9% sand, 31.9% silt, 30.2% clay, 4.2% organic carbon, pH 7.6) and 92 in cultivated soil (36.8% sand, 29.5% silt, 33.7% clay, 2.5% organic carbon, pH 7.6)(9). According to a classification scheme(10), these Koc values suggest that atrazine is expected to have very high to slight mobility in soil, depending upon soil type(SRC). The rate constant for sorption and desorption of atrazine by organic soil at 25 deg C was determined to be 5.02X10-2/day (half-life = 13.8 days) for sorption and 0.1507/day (half-life = 4.6 days) for desorption(11). Atrazine sorption half-life ranged from 3.6 to 735 days and desorption half-life ranged from 1 to 11 days in slurries of a mineralized soil(12).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
