a b s t r a c tBroiler husbandry is a significant source of ammonia (NH 3 ), nitrous oxide (N 2 O), carbon dioxide (CO 2 ) and methane (CH 4 ) emissions but scarce studies have been made under Mediterranean conditions. The aim of this study was to evaluate the NH 3 , N 2 O, CO 2 and CH 4 emissions on commercial broiler houses under Portuguese winter conditions. The study was made on a commercial broiler farm located in central Portugal. Three tunnel ventilated broiler houses with similar equipment and production practices were selected. The outdoor and indoor environmental conditions, gas concentrations and ventilation rates of each broiler house were measured during 42 days of growing cycle. Results showed that the maximum concentrations of NH 3 , N 2 O, CO 2 and CH 4 did not exceed the threshold values recommended to maintain indoor air quality on broiler houses. The average emission rates from broiler houses under winter conditions were 0.13 ± 0.04, 0.041 ± 0.002, 96.2 ± 8.8 and 0.226 ± 0.013 g day À1 bird À1 (22.0 ± 7.3, 6.7 ± 0.3, 16,028 ± 1465 and 37.7 ± 2.1 g day À1 LU À1) for NH 3 , N 2 O, CO 2 and CH 4 , respectively. Furthermore, NH 3 and N 2 O emission rates of this study are in the same range than measurements from most European countries, but CH 4 emission rate seems higher to those reported for Mediterranean countries.

“…The largest uncontrolled emission of ammonia to the environment comes from livestock breeding, manure management, and fertilizer application. In case of insufficient ventilation of the breeding rooms, respiratory diseases appear in the animals, which results in a decrease in the production of milk, meat, and eggs (Alberdi et al 2016;Henry and Aherne 2014). Currently used techniques of removing ammonia from water and wastewater are biological method using activated sludge to remove nitrogen compounds in sewage treatment plants, division in the air stream, and ion exchange carried out in columns with zeolite filling, chemical precipitation, ion exchange, membrane separation (Zhang et al 2009;Jorgensen and Weatherley 2003;Shalini and Joseph 2012;Huang et al 2015).…”

The study investigated the sorption capacity of biosorbent-raphia sp. against ammonia. Raphia fibers were used without and with the modification of its surface with NaCl, NaNO 3 , and K 2 SO 4 . The data was analyzed in the state of equilibrium using four isotherm models such as Langmuir, Freudlich, Temkin, and Dubinin-Radushkevich. The equilibrium of ammonia sorption for all studied systems was best described by the Freudlich isotherm model. On its basis, it can be assumed that the studied process is of chemical nature, which results from the value of the coefficient 1/n < 1. In order to confirm the sorption mechanism, analysis of the kinetics of the ammonia sorption process on raphia fibers was performed. Four kinetic models of sorption were calculated: pseudo-first-order model, pseudosecond-order model, Elovich model, and Webber-Morris intermolecular diffusion model. The sorption kinetics of the modeled ammonia waste were carried out using unmodified palm fibers and all kinds of surface modification. This process was best described by the pseudo-second-order sorption model, which can be considered as a confirmation of the chemical nature of ammonia sorption on raphia sp. fibers.

The article investigates the scientific literature regarding N 2 O emissions according to housing and manure management in poultry and pig buildings. The majority of the N 2 O is emitted from manure storages and housing space, with small amounts emitted from the surface of passages. Many factors must be considered in successful emission evaluation, including season of the year, amount and depth of the bedding, animal density, type and floor space, feeding and watering practices, ventilation, temperature, and relative humidity. The liquid manure from poultry housing systems produces greater emissions of N 2 O than natural and force-dried manure. The influencing factors appeared to be manure removal frequency and the dry matter content of the manure. There are more housing types in pig barns, which differ in bedding, floor, and manure deposition. The highest N 2 O emissions were found in the sawdust bedding, and N 2 O production in slatted floor housing is lowest. This paper reports on technical options for mitigating emissions from poultry and swine contributions. The actual rate of N 2 O emission is highly dependent on the management strategies implemented on a farm. Consequently, improvements in management practices will affect future N 2 O emissions. Finally, emission factors are listed in a table.
