12.2 Persistence and degradability
AEROBIC: Using a Zahn-Wellens test(2), which requires a 0.2 - 1.0 g/L dry inolculum and 50-400 dissolved organic carbon/L test concentration(1), analogous methylparaben degraded 100% after 6 days with a 2 day acclimation period in a sludge inoculum(2), suggesting that propylparaben may be subject to biodegradation(SRC). Average concentrations of 2.9, 0.21, 0.72 and 0.11 ng/L were reported for propylparaben in gray water from 32 residences and associated effluent from aerobic, anaerobic and anaerobic+aerobic biological treatment systems, respectively. Testing was done in August, 2008 in Sneek, The Netherlands. Propylparaben removal was postulated to be a combination of adsorption and biodegradation, with a 92.8% removal observed using aerobic treatment(3). Propylparaben, present at an average concentration of 1400 ng/L, exhibited half-lives of 2.7 days and 20.3 hours using an activated sludge batch test and a real wastewater treatment plant test, respectively; sampling was conducted during April and May 2010 in a metropolitan area of northwest Spain(4).
12.3 Bioaccumulative potential
An estimated BCF of 50 was calculated for propylparaben(SRC), using a log Kow of 3.04(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of propylparaben can be estimated to be 290(SRC). According to a classification scheme(2), this estimated Koc value suggests that propylparaben is expected to have moderate mobility in soil. The estimated pKa of propylparaben is 8.5(3), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
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.
Contaminated packaging
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.
