“…A major challenge for the agricultural sector today is to produce more and safe food for a growing global population. Meat and dairy products are parts of the livestock industry and the use of synthetic steroid hormones as growth promoters (Bartelt-Hunt et al, 2012), increasing the muscle mass (Biswas et al, 2013) are the mostly adopted practices in the developed countries.…”

“…After excretion in feces or urine, hormones and metabolites generally change forms through chemical and microbial transformation [11,12]. Both natural and synthetic hormones and their metabolites have been detected in manure, soil and wastewater of cattle feedlots [13][14][15][16].…”

h i g h l i g h t s• Hormones and metabolites were detected in runoff from test plots fertilized with cattle manure.• Composting can reduce the hormone concentration in manure compared to stockpiling.• About 10% of applied hormones can be lost through the dissolved phase of runoff. a r t i c l e i n f o a b s t r a c tRunoff generated from livestock manure amended row crop fields is one of the major pathways of hormone transport to the aquatic environment. The study determined the effects of manure handling, tillage methods, and rainfall timing on the occurrence and transport of steroid hormones in runoff from the row crop field. Stockpiled and composted manure from hormone treated and untreated animals were applied to test plots and subjected to two rainfall simulation events 30 days apart. During the two rainfall simulation events, detection of any steroid hormone or metabolites was identified in 8-86% of runoff samples from any tillage and manure treatment. The most commonly detected hormones were 17␤-estradiol, estrone, estriol, testosterone, and ␣-zearalenol at concentrations ranging up to 100-200 ng L −1 . Considering the maximum detected concentrations in runoff, no more than 10% of the applied hormone can be transported through the dissolved phase of runoff. Results from the study indicate that hormones can persist in soils receiving livestock manure over an extended period of time and the dissolved phase of hormone in runoff is not the preferred pathway of transport from the manure applied fields irrespective of tillage treatments and timing of rainfall.

“…Testosterone has been detected in groundwater (Wicks et al 2004;Swartz et al 2006;Arnon et al 2008), surface waters (Koplin et al 2002), soils (Finlay-Moore et al 2000), and sediments (Campbell et al 2006). Although sorption and degradation of testosterone in the environment have been extensively studied (Lee et al 2003;Casey et al 2004;Sangsupan et al 2006;Arnon et al 2008;Ma 2009), the current knowledge cannot fully explain the occurrence and persistence of testosterone in the environment (Bartlet-Hunt et al 2012;Biswas et al 2013a).…”

In this study, batch sorption and desorption experiments were conducted for testosterone using four agricultural soils and five clay minerals. Significant differences in sorption behavior were observed between abiotic and biotic systems. The Freundlich sorption coefficient K f ðμg=gÞ=ðμg=mLÞ n ranged from 8.53 to 74.46 for soils and from 35.28 to 1,243 for clays. The maximum sorption capacity (μg=g) of soils ranged from 25.25 to 440.61 for soils and from 168.46 to 499.84 for clays. Correlation of the sorption model parameters with the soil properties indicated that both clay content and soil organic matter are important variables in predicting testosterone sorption behavior. Observed testosterone desorption from agricultural soils ranged from approximately 14 to 100% after three desorption cycles, and the desorption percentage decreased as the initial testosterone concentration decreased. It was determined that the temperature, ionic strength, water/soil ratio, and soil depth influenced the sorption and desorption of testosterone. Desorption significantly increased with the soil depth (p < 0.05) and with the increase in the water/soil ratio. Temperature had an inverse effect on the sorption capacity of the soils tested. Thermodynamic calculations showed that the enthalpy change (ΔH 0 ) of the soils tested ranged from 12.9 to 20.7 kJ=mol, indicating a weak interaction between the testosterone and soil. The authors' results suggest that additional studies on how soil particles with different size fractions affect hormones' fate and transport are needed to determine the potential risk of testosterone leaching or runoff.
